Hi,

I noticed that some times the size of the image actually increases.
For ex an image 170 KB increase to 204 KB.

This happens rarely but it would be good if there was an inbuilt way to check if any image compression took place.

THe Png images loose there transparency

Web server: NGINX
PHP Version: 5.5.9-1ubuntu4.14

I am getting this error Final image URL is broken. The page looks like this

There should be 100 images displayed but it dies at the third.

It is returning this url
There should be a / between the mediapage.zips.me and core, however it is a local image so I don't see why it should even need the host name.

How I am doing this is,

On the top of each page I am calling another page which contains the setup of the class

<?php
    //Calls the php-image things
    include 'test.php';

?>

Inside test.php

<?php 
    require_once 'core/classes/ImageCache.php';
    $imagecache = new ImageCache();
?>

Image page

<?php 
    //Directory NON-CACHED images are stored in
    $dir    =   "i/";

    //Array of files in the Directory
    $files1 =   scandir($dir);
    //Used to limit results (100's of images)
    $count = 0;
    foreach ($files1 as $key) {
        //If the file name is longer than 3 chars and the count is less 
        //than the amount of images I want displayed.
        if (strlen($key) > 3 && $count <= 100){
            $count++;
            //dir2 is the directory/nameofFile.extension
            //Eg: i/testImage.png
            $dir2   =   $dir.''.$key;
            $info = new SplFileInfo($key);
            //Image Cache variable
            $cached_src = $imagecache->cache($dir2);
?>
    <tr>
        <td>
            <!-- Link for light box for full resolution image -->
            <a href="<?php echo $dir2;?>" data-popup="lightbox">
                <!-- src of cached image is outputted and the alt is the name of the uncached image. -->
                <img src="<?php echo $cached_src;?>" alt="<?php echo $key;?>" class="img-rounded img-preview">
            </a>
        </td>
        <!-- More table stuff... -->
    </tr>

<?php
        } //End If
    } //End for
?>

The docs located at:

http://nielse63.github.io/php-image-cache/

Do not match the functionality at all. For example:

$image = new ImageCache(
    $filebase = '', $dir = null, $create_dir = true, $opts = array()
);
/**
 * @param $filebase (string) - The base URL that will be included in the final output for the image source; primarily used if you want the image source to be an absolute URL; defaults to relative.
 * @param $dir (string/null) - The base directory that houses the image being compressed; defaults to the location of ImageCache.php.
 * @param $create_dir (bool) - Whether or not to create a new directory for the compressed images; defaults to "true"
 * @param $opts (array) - An array of available options that the user can include to the overwrite default settings.  Mostly just for forward-compatibility at the moment.
 */

In the code the constructor actually accepts 3 parameters, 2 of which will be deprecated soon!

Very confusing.

Error behaviour is also completely undocumented.

I am having trouble displaying the compressed Image on my local server(WAMP).
The image compression works perfectly, but when I try to echo out the image in tag, it displays a broken image.

Heres my folder structure:

sample (root folder)
-images (inside sample)
-cached (inside images, here's where the cached file goes)
-f3ccdd27d2000e3f9255a7e3e2c48800.jpg(cached image)
-1.jpg (Image to be compressed, inside images folder)
-ImageCache.php (inside sample)
-index.php (inside sample)

Thanks!

Hey,

I am experiencing an issue.
I can successfully shrink and cache the image but I am getting a blank page.

How can I fix this?

Update: Apparently this is caused by an error made by ImageCache.php: "Final image URL is broken".
I used this guide to solve it

I am trying to use PHP Image Cache. But have run into some issues. I have managed to get the script to somehow function (I think). But it seems that my images aren’t being cached correctly. The files are 0kb in size. I am developing on a local system running MAMP (not sure if this is the issue). Here is how i execute the script:

http://pastebin.com/EJJmkcvi
AND
http://pastebin.com/dStWtUGR

Path of my files:

top / images / letters / (here is all the images i am trying to cache)
top / images / letters / cached / (here is the 0kb sized images that is being somehow cached)
top / scripts / ImageCache.php
top / scripts / funcs.php

Can there be an option for the returned value of the cache function to be the cached image src and not a url version of it.

Hello, I download the latest version, then transfer to my server but when I run the demo I have two PHP error ?

Warning: Unexpected character in input: '' (ASCII = 92) state = 1 in / fximg/new/demo/index.php on line 16

Parse error: syntax error, unexpected T_STRING in / fximg/new/demo/index.php on line 16

What it comes from my version of PHP ? ... or something else!

help me please ;)

I think your script is not user friendly... just to configure your script we need more time... and there are soo many functions missing.... i really wanted to use your script.. but i keep getting errror message ...and these error error message can be answered only by you.. " Call to undefined function ImageCache\curl_init() in C:\wamp\www\icon\src\ImageCache\ImageCache.php " dont know why have you desghned this?? there is no documentation also.. serioously i wasted my time.. even stack experts could not find solutions for your script bugs...if you really want to make this as popular script.. please write a good documentation, each and every line on how to work on your script... forget about script updation, first let the basic things work...Sorry but that's what i found....

private function is404($source) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $main_url);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_exec($ch);
if (curl_getinfo($ch, CURLINFO_HTTP_CODE) == '404')
return $this->show404();
return false;
}

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: main_url

Line Number: 232

The documentation of PHP does not allow strtotime() empty.

Error:
strtotime() expects at least 1 parameter, 0 given

File: /src/ImageCache/ImageCache.php

Fix:
Add 'now' in strtotime(), or switch to time()

Hi,

Yesterday I used ImageCache class to cache some images on my website. I noticed, that when $_SERVER['DOCUMENT_ROOT'] = '/', then solution presented currently in ImageCache.php is going to replace all occurences of slash, which results in incorrect source string.

For example, if resulting string should be: /path/to/img , then after using makesource function, we've got: pathtoimg.

I've done some workaround for it, which works for me:

private function makesource( $dir ) {
        $cururl = strtolower( reset( explode( '/', $_SERVER['SERVER_PROTOCOL'] ) ) ) . '://' . $_SERVER['SERVER_NAME'];
        $base = $_SERVER['DOCUMENT_ROOT'];

        if($base == '/')
        {
            $localpath = substr($dir, 1);
        }else{
            $localpath = str_replace( $base, '', $dir );
        }

        return $cururl . $localpath;
}

Best regards,
Mike

I am trying your class with JPG file getting lot of errors

first was "The file you supplied isn't a valid image."

Then I commented the if condition just to check, then got "The image you supply must have a .gif, .jpg/.jpeg, or .png extension." Then I checked "$file_mime_as_ext" and it dump "octet-stream" for jpg file. I know it's some kind of mime problem. Any idea how to fix it?

Thanks in advance

Can the class refresh images so user's browsers download the new image every x minutes ?

../images must writable! is being displayed on the php page

This is the line of code which I believe is giving the problem

$cached_src_one = $imagecache->cache( '../images/background.jpg' );

I am running the php page from where the images folder is found.

I'm using Silverstripe (framework) hosted in a Linux server.
The framework default upload folder name contains a Uppercase Letter ("assets/Uploads").
When we call the method cache(), it uses 'strtolower' in the folder name turning it to "assets/uploads" which generates an error on trying to find the image since its address is wrong. It must keep the uppercase "U" in "Uploads".

Hello.
Based on this statement:

imagejpeg( $image, $newlocation, $this->opts['quality'] );

an image is always converted as a JPG image. Why it can't be saved as its previous format?

Warning: imagejpeg(C:\xampp\htdocs\php-image-cache-master\demo/images/cached/ccc2078020a3fec0056ed59b53a7bf2d.jpeg): failed to open stream: No such file or directory in C:\xampp\htdocs\php-image-cache-master\src\ImageCache\ImageCache.php on line 230
Could not copy image resource.

"It showing error like this how should i give input(Url) please suggest me"

This would allow a much proper use with Composer. Is it something you would be ok for a PR ?
