Hi guys

I am gonna make next version 2.0

• The current one is 1.3 will be keep going improve and fix bugs. I will not remove current version on future, and I will keep develop it as one file / one static class for who is using it.
• The version 2.0 will on schedule working, and will be publish together with current version.

Reason to plan to 2.0 are:

• One Class can't handle everything. It makes it
  painful to add a new backend (redis, apcu, tokyotyrant, mongodb, ...) or
  modify an existing one.
• Need responsability in case you want to keep the possibility to have multiple
  backends.
• Factory method instead, maybe a singleton method if necessary

In design for phpFastCache in my head right now:

• Not use static any more;
• phpfastcache_get(); phpfastcache_set();
• phpfastcache.php
• phpfastcache_class/apc.php ; wincache.php ; xcache.php .. etc

It easy to add new class, upgrading, bugs, and easy to save memory when u don't need other class loading.

Any ideas reply at this topic.

If you have any questions or you need my help, just create a topic here.

I will take care it on couple hours.

You can also skype me: khoaofgod

*** PLEASE do not reply this topic, just create new one ^_^ Thanks, dude.

Warning: readdir() expects parameter 1 to be resource, string given in phpfastcache.php line 148

I'm not quite sure what this means but here is my script:
$cache = phpFastCache();
$full_product_list = $cache->get("products");
if ($full_product_list == null)
{
$full_product_list = $dbh->fetch_rows($query_products);
$cache->set("products",$full_product_list, 5); // 600
}

Hallo Khoafgod...

I am trying phpfascache but I get error "Please re-upload the caching file caching.0777 and chmod it 0777 or Writable permission!"

I am using Mac with Mamp Pro and I have change attribut the caching.0777 writable...
Do you know what exactly my problem?

Thanks

When requesting stats() from the cache object, it returns a error that the table caching does not exist.

(line 303 in sqlite.php)

If I comment those line 303 - 307 the stats() keeps returning 0 for each value in the array.

Helo Khoafgod...

I want to ask about Cache PATH, I have set cache path to another path but it's still in current directory, how to fixed it?
Example :
phpFastCache::$path = SRV_ROOT.CACHE;// absolute path

I look at Line 162 self::$path = dirname(FILE);
how about if dirname(FILE) change to user defined parameter?

if php_fast_cache.php in my folder directory like library/php_fast_cache.php
so it will create in library folder not in SRV_ROOT.CACHE; (user defined)

Thanks...

Feature-Request: A Packagist-Entry for PhpFastCache.

https://packagist.org/

I couldn't cache mysql queries. Can you show an example pls?

Apache 2.4 PHP 5.4 (Windows Server 2008 x86)

Warning: unlink(C:\...//sqlite/indexing): Permission denied in C:\...drivers\sqlite.php on line 328

I usually see that kind of error when there is a process not releasing the handle of those files.

Step to reproduce

<?php
require_once 'C:\xampp\htdocs\www.test.it\phpfastcache\trunk\phpfastcache_v2.1_release\phpfastcache\phpfastcache.php';

class MyCache extends phpFastCache
{
    private static $istance;
    Private $obCache;

    function __construct()
    {
                $option = array('securityKey' => 'aCache', 'path' => dirname(__FILE__));
        $this->obCache = parent::__construct('sqlite', $option);
    }

    public static function getIstance()
    {
        if( is_null(self::$istance) )
        {
            self::$istance = new self();
        }

        return self::$istance;
    }
}

if( $CacheData = MyCache::getIstance()->get('aKeyword') )
{
    die($CacheData);
}

MyCache::getIstance()->set('aKeyword','aValue', 60*60*24);

MyCache::getIstance()->clean();

echo 'No cache'; 
?>

If I tried to get data from Cache file

$somedata = phpFastCache::get("myCacheVar");
if($somedata == null)
{
$somedata = "";
phpFastCache::set("myCacheVar",$somedata,60);
}
echo $somedata;

Because $somedata is an empty string it echo what between brackets (N;) or (s:0:"";)
It should echo an empty string

the website codehelper.io is not accessible since several days. Inside the files there is a relation with this website, the add on does'nt wok now.

Hello Khoa,

Phpfastcache with detect_visitor_location does'nt work. codehelper.io is down, Have a delay to fix it or what I can do to resolve this problem ?
Thank you.

i see your are using a function to send bug errors via email. this section must be more configurable via public properties such as destination email, using SMTP (some hosting has blocked local smtp to prevent spam attack) i think you could integrate directly to php mailer line $mail = new PHPMailer();... and so on.. user must have phpMailer class in their server. and you should let user to set the path of php mailer class and "include_once" into the function (include files only if needed).

sorry for my bad english.

Hallo
I have a issued about pdo cache.

I created a modul for cron job, in cron job need to create a folder
cache/f011sdfasddsd8efed7as420323c793/ exampled. In these folder will be consist two files they are :
pdo.caching and config.41065cf4fd8asdf 7d52bedfda24a32adf75b1fe0.cache.ini

And I am considering for chmod it 0777 or Writable permission, I am afraid if some body can download these file via browser. I have test and it can be downloaded.

Other modul I set automatically, other module created cache APC, so I look cron job module and others moduls have created different cache, they are still in one application.

How to set chmod not to 0777 but still created pdo cache.

Thanks

hello,
i have downloaded phpfastcache from github..i am not getting the proper way to use it.
i have included
include("php_fast_cache.php");
phpFastCache::$storage = "auto";

i am not understanding few terms being used further like "product_page" and "identity_keyword"

Hello Khoaofgod...

I want to ask about time of cache..

What do you mean 600 seconds = 5 minutes?

We know that 300 seconds = 5 minutes?

600 seconds = 10 minutes

I think it can make confuse in documentation and uses.

Maybe you have reasons, could you tell me?

Thanks...

Hallo Khoafgod...

I have get error when update phpfashcache, the error is "Don't have this Cache xcache In your System! Please double check!"

I think I have xcache installation in my Mamp OS X SL

How to fixed it?

Thanks

Sorry if this is answered elsewhere, but I do not see any specific support planned for Redis. Do you plan to have support for it in the future?

X-Cache have supported.

phpFastCache::$storage = "xcache";

All bugs about x-cache please report here.

AUTO Mode Priority: APC, XCache, MemCached, MemCache, WinCache, PDO, Files

* phpFastCache::$useTmpCache = true; // default is FALSE
// faster checking cache for LOOP Only. If you don't use LOOP, don't spend more memory.
* Example:
* WHILE() {
*   $cache = phpFastCache::get("name");
* }
* LOOP() {
*   $cache = phpFastCache::get("name");
* }
*    --> THE NAME maybe duplicated some times, if you set $useTmpCache it will check from $Tmp first before IT connect to Cache Memory or Open Files to check.
*        Will be faster a little bit if you know what you are doing.

As another topic about auto clean up files cache.
The core right now added auto clean up files cache every 1 hour for "files" cache only.
You can do custom config by:

phpFastCache::$files_cleanup_after = 1; // hours(s)

Let me know if any bugs & issues OR This topic will be close at end of this month.

HI,

I just downloaded the script and tested it, but i am getting this error when testing.php

Caching = auto
SET 1 -->
Fatal error: Call to a member function prepare() on a non-object in /public_html/phpfastcache/php_fast_cache.php on line 1665

I also get this error when trying the script with "auto" selected, works only when set o PDO.

Fatal error: Call to a member function prepare() on a non-object in /public_html/phpfastcache/php_fast_cache.php on line 1575

Hi, i testing performace for cache aaand
first ist APC (best performace) +- 70ms
sqlite +- 320ms
files +- 70ms

then order is wrong... second sqlite si very slow

Dear Khoaofgod, suddenly in one of my projects, a fatal error displayed, and it cause some sections to be die.
This is the error message:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 5 database is locked' in /home/estqlal/public_html/includes/phpfastcache/drivers/sqlite.php:272 Stack trace: #0 /home/estqlal/public_html/includes/phpfastcache/drivers/sqlite.php(272): PDOStatement->execute(Array) #1 /home/estqlal/public_html/includes/phpfastcache/drivers/sqlite.php(244): phpfastcache_sqlite->deleteRow(Array) #2 /home/estqlal/public_html/includes/phpfastcache/phpfastcache.php(98): phpfastcache_sqlite->driver_get('SidebarArticles', Array) #3 /home/estqlal/public_html/sidebar.php(20): phpFastCache->get('SidebarArticles') #4 /home/estqlal/public_html/index.php(161): require_once('/home/estqlal/p...') #5 {main} thrown in /home/estqlal/public_html/includes/phpfastcache/drivers/sqlite.php on line 272

I think it will be a more great project:)

i want to write a simple file cache,find some ideals from your code,thanks

Does the fallback concept work? It doesn't for me. I just get an exception that says "Can't use this driver for your website!" when I try to use memcached with a fallback of files.

Here's my code.

$options = array(
    'fallback' => array(
        'memcached' => 'files'
    )
);
$cache = $cache = new phpFastCache('memcached', $options);

But looking through the phpfastcache code, I don't see any exception catching. Searching for the word fallback seems to result in almost nothing. It doesn't look like it could work.

how can i solve this code problem?

I'm trying to download the project with the use of the composer but I always get an error.

I'm using the command:
php composer.phar require "phpfastcache/phpfastcache":*

and I get:
Your requirements could not be resolved to an installable set of packages.

Problem 1
- The requested package phpfastcache/phpfastcache could not be found in any version, there may be a typo in the package name.

Potential causes:

• A typo in the package name
• The package is not available in a stable-enough version according to your minimum-stability setting
  see https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion for more details.

Read http://getcomposer.org/doc/articles/troubleshooting.md for further common problems.

Installation failed, reverting ./composer.json to its original content.

Is this method supported ?

Do you plan to implement REDIS ? :) is faster than memcache and APC :)

If I want to set the cache never expire, how do I do? Set the time to 0?
Thank you khoaofgod.

Dear phpfastcache developers,

With the announcement of the end of support of APC within PHP 5.5.x and its replacement by OPcache, is there any plan to update the library to support OPcache ?

Thanks a lot and best regards,

Alexandre 8)

I have a "Call to a member function prepare() on a non-object in /php_fast_cache.php on line 1536" Fatal error when trying to: $recentArticles = phpFastCache::get("recentArticles");

This problem disappears when I add a 'phpFastCache::$sys['method'] = "pdo";' line to the code. Why is it so?

Due to heavy visitors traffic & my periodic dynamic content, the cache file is growing up to fast, what logic should I use to dynamically delete old cache.

My Regards

Hallo Khoaofgod...

I using cronjob to run php script, but in log error i got this

[04-Jan-2014 12:09:01 Asia/Jakarta] PHP Warning: xcache_get() [function.xcache-get]: XCache var cache was not initialized properly. Check php log for actual reason in /home/xxx/public_html/new/libraries/php_fast_cache.php on line 1114

[04-Jan-2014 12:09:01 Asia/Jakarta] PHP Warning: xcache_set() [function.xcache-set]: XCache var cache was not initialized properly. Check php log for actual reason in /home/xxx/public_html/new/libraries/php_fast_cache.php on line 1105

How to fix it? I am using phpfastcache Revision 620

I just started messing around with this. Works great so far. I was wondering if it's possible to manually delete cache files when you are using filesystem storage as the caching type? I don't see where the cache files are stored on the file system.

There are some cases where I need to manually delete the cache and let my webpage rebuild the cache because a DB query was modified and I can't wait until the cache expires. Is the only way to delete the cache to call $cache->delete()?

For me xcache_cleanup gets this error:

Warning: xcache_clear_cache() expects exactly 2 parameters, 1 given in /PATH/TO/FILE/php_fast_cache.php

so i've modified the function like this:

private static function xcache_cleanup($option = array()) {
$cnt = xcache_count(XC_TYPE_VAR);
for ($i=0; $i < $cnt; $i++) {
xcache_clear_cache(XC_TYPE_VAR, $i);
}
return true;
}

and all works file when i call: phpFastCache::cleanup();

Hello,

I use your phpfastcache and have a question:

how do I disable phpfastcache temporarily.

many greetings

Richy

$cache2->setMulti(array("key1","value1", 300),
array("key2","value2", 600),
array("key3","value3", 1800),
);

Maybe the last comma is redundant?

Hi,

Using the master phpfastcache_v2.1_release/phpfastcache/phpfastcache.php

I get a warning about $_SERVER['HTTP_HOST'] not existing when I use phpfastcache in a command-line php script which I have to fix with:

if (empty($_SERVER['HTTP_HOST'])) { // patch for phpfastcache referencing this
$_SERVER['HTTP_HOST'] = 'localhost';
}

Please could you remove such references or enable them to be set?

Hi Khoaofgod
Sometimes the website is down and receive this error message "Please re-upload the caching file pdo.caching and chmod it 0777 or Writable permission!", how to solve it

Thanks

Supported APC, Memcached, Wincache, and Files
We are working on this one.

As my schedules, this task will be finish before July 2013.

If I want to add some additional options for memcached, like compression it is hard to do because memcached_addserver method is private not protected.

Is it possible to add phpDoc compatibile syntax to each function (public are more important than the others).

Release 2.4 will be release on next Monday Feb 02.

What's new

• Redis supported
  "pecl install redis"
• Cookie Driver
  Fun for who want to store cache on visitor's browser.
• Non-Expring Cache for Object
  Example: set("keyword", $data); will be non-expire until you do delete("keyword");
• Temporary Disabled phpFastCache
  use: phpFastCache::$disabled = true;
  After this line, all get("keyword") will return NULL;
• Improved Files Cache for Busy Disk
  Busy Disk will skip caching object and continue without error_log problems.
• Composers will be added
• Improve fallback
  If specific driver that you set is not available then system will use "files" driver

Then March 03 will be release 2.5:
-- Planned for MongoDB
-- External Server Caching
-- and phpFastSQL.com will be release together.

I was adding a Redis driver when I spotted this:

$object being returned from

   function get($keyword, $option = array()) {
        if($this->is_driver == true) {
            $object = $this->driver_get($keyword,$option);
        } else {
            $object = $this->driver->driver_get($keyword,$option);
        }

        if($object == null) {
            return null;
        }
        return $object['value'];
    }

is not the entire array and only the 'value' so:

    function increment($keyword, $step = 1 , $option = array()) {
        $object = $this->get($keyword);
        if($object == null) {
            return false;
        } else {
            $value = (Int)$object['value'] + (Int)$step;
            $time = $object['expired_time'] - @date("U");
            $this->set($keyword,$value, $time, $option);
            return true;
        }
    }

    function decrement($keyword, $step = 1 , $option = array()) {
        $object = $this->get($keyword);
        if($object == null) {
            return false;
        } else {
            $value = (Int)$object['value'] - (Int)$step;
            $time = $object['expired_time'] - @date("U");
            $this->set($keyword,$value, $time, $option);
            return true;
        }
    }

    function touch($keyword, $time = 300, $option = array()) {
        $object = $this->get($keyword);
        if($object == null) {
            return false;
        } else {
            $value = $object['value'];
            $time = $object['expired_time'] - @date("U") + $time;
            $this->set($keyword, $value,$time, $option);
            return true;
        }
    }

will not work and will also mess up the cached values.

I'm fixing it by passing an option to the get method so it returns the entire array.

Will send a Pull request for both this issue and the Redis driver once resolved and tested.

It's not a bug or error, but I would like also to cache CSS & JS files to speed loading those files.
Is it supported ?

The file cache is deleted on server restart. I would like it to remain and honour the expiry I have set which in my case is 28 days.

I'd like to clear a section of my cache. Say for example that I store data by prefixing it with a namespace. Perhaps I cache some twitter data, facebook data, etc. I might store them as twitter.myvalue1, twitter.myvalue2, and facebook.myvalue1, facebook.myvalue2. How could I delete the cache entries for twitter? And I don't know all the names of the values. It's not necessary myvalue1/2/3/etc, I just know it starts with twitter.

Hello,
Introduction of tags will be?

I will clean up the issues soon, because I am opening a forum to do support & continue develop other plugins for wordpress , carts , forum use phpFastCache.

This box gonna do issues only.

Skype me: If you have any problem or need fast support.
