1. Download and extract a release archive to directory of your choice

2. Create a base directory for PHP with the following structure:

   %phpDir%/
   ├── configurations/
   │   ├── 5.x.x.ini        # php.ini options for all 5.x.x versions
   │   ├── 5.3.x.ini        # php.ini options for all 5.3.x versions
   │   ├── 5.3.7.ini        # php.ini options specific for 5.3.7 version
   │   └── ...
   └── versions/
       ├── 5.3.7/
       │   ├── ext/
       │   ├── ...
       │   └── php.exe
       ├── 5.6.0-rc3/
       │   ├── ext/
       │   ├── ...
       │   └── php.exe
       └── ...
   

3. Create php.ini files in the configurations directory. In all php.ini files you can use %phpDir% variable. This is especially useful for zend_extension, e.g.

   zend_extension = "%phpDir%\ext\php_opcache.dll"
   zend_extension = "%phpDir%\ext\php_xdebug.dll"
   

4. The active PHP version is always symlinked to %phpDir%\active. You may want to add this directory to PATH.

5. Update phpDir option in PhpVersionSwitcher.json to contain path to the base PHP directory.

1. Add Apache service definition under services key:

   {
   	"services": [
   		{
   			"label": "Apache 2.4",
   			"name": "Apache2.4"
   		}
   	]
   }
   

2. Update Apache configuration to contain something like this:

   LoadModule php5_module "C:/web/php/active/php5apache2_4.dll"
   PHPIniDir "C:/web/php/active"
   AddHandler application/x-httpd-php .php
   

3. You can use PHP_VERSION_MAJOR variable in Apache configuration file. This is useful when you switch between PHP 5 and PHP 7 versions:

   LoadModule php${PHP_VERSION_MAJOR}_module "C:/web/php/active/php${PHP_VERSION_MAJOR}apache2_4.dll"
   

1. Add Nginx and PHP FastCGI definitions under executables key:

   {
   	"executables": [
   		{
   			"label": "Nginx 1.9",
   			"path": "C:\\web\\nginx\\nginx.exe"
   		},
   		{
   			"label": "PHP FastCGI",
   			"path": "C:\\web\\php\\active\\php-cgi.exe",
   			"multiple": [
   				{"args": "-b 127.0.0.1:9300", "label": "PHP FastCGI (9300)"},
   				{"args": "-b 127.0.0.1:9301", "label": "PHP FastCGI (9301)"},
   				{"args": "-b 127.0.0.1:9302", "label": "PHP FastCGI (9302)"},
   				{"args": "-b 127.0.0.1:9303", "label": "PHP FastCGI (9303)"},
   				{"args": "-b 127.0.0.1:9304", "label": "PHP FastCGI (9304)"},
   				{"args": "-b 127.0.0.1:9305", "label": "PHP FastCGI (9305)"},
   				{"args": "-b 127.0.0.1:9306", "label": "PHP FastCGI (9306)"},
   				{"args": "-b 127.0.0.1:9307", "label": "PHP FastCGI (9307)"},
   				{"args": "-b 127.0.0.1:9308", "label": "PHP FastCGI (9308)"},
   				{"args": "-b 127.0.0.1:9309", "label": "PHP FastCGI (9309)"}
   			]
   		},
   	]
   }
   

2. Update Nginx configuration to contain something like this:

   upstream php_farm {
   	server 127.0.0.1:9300 weight=1;
   	server 127.0.0.1:9301 weight=1;
   	server 127.0.0.1:9302 weight=1;
   	server 127.0.0.1:9303 weight=1;
   	server 127.0.0.1:9304 weight=1;
   	server 127.0.0.1:9305 weight=1;
   	server 127.0.0.1:9306 weight=1;
   	server 127.0.0.1:9307 weight=1;
   	server 127.0.0.1:9308 weight=1;
   	server 127.0.0.1:9309 weight=1;
   }
   
   location ~ \.php$ {
   	fastcgi_pass   php_farm;
   	fastcgi_index  index.php;
   	fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
   	include        fastcgi_params;
   }
   

1. Add definition under executables key:

   {
   	"executables": [
   		{
   			"label": "PHP built-in server",
   			"path": "C:\\web\\php\\active\\php.exe",
   			"args": "-S 127.0.0.1:9990 -t C:\\projects"
   		}
   	]
   }
