Installing PHP FastCGI and Zend OPcache on XAMPP for Windows

Written by

Why install PHP + FastCGI?

Mod-PHP comes installed with XAMPP, and it is slow.

You also cannot utilise the Zend opcode cache, which is included with PHP itself since PHP 5.5.

Steps to install PHP + FastCGI

  1. Identify the version of Apache server that is running. Tips: visit on your browser. Search for the SERVER_SOFTWARE environment variable, which will indicate Apache version. (Example: Apache/2.4.4 (Win32) OpenSSL/1.0.1g PHP/5.4.16 ).
  2. Download mod_fcgid binaries for windows. Extract the files and copy “” into the apache modules folder. The default folder path will be “C:\xampp\apache\modules”.
  3. Download the latest PHP binaries for windows. (Link: Choose the non-thread-safe (nts) version for fastcgi usage. The default PHP installation in XAMPP is thread-safe (ts) and will be replaced later. Create a folder (eg: C:\Xampp\php5.5.12-nts) for your new php installation. Extract and copy all the files into the folder.
  4. Edit the Apache configuration file. Open the file “C:\Xampp\apache\conf\extra\httpd-xampp.conf” in a text editor such as Notepad++.
    • Look for the section PHP-Module setup. Disable mod_php by commenting out them as below:
      # PHP-Module setup
      #LoadFile "C:/xampp/php/php5ts.dll"
      #LoadModule php5_module "C:/xampp/php/php5apache2_4.dll"
      #<FilesMatch "\.php$">
      #    SetHandler application/x-httpd-php
      #<FilesMatch "\.phps$"">
      #    SetHandler application/x-httpd-php-source
    • Enable mod_fcgid by adding the following lines after the section:
      # PHP-FastCGI setup
      LoadModule fcgid_module modules/
      <IfModule fcgid_module>
      	FcgidInitialEnv PATH "C:/Xampp/php5.5.12-nts;C:/WINDOWS/system32;C:/WINDOWS;C:/WINDOWS/System32/Wbem;"
      	FcgidInitialEnv SystemRoot "C:/Windows"
      	FcgidInitialEnv SystemDrive "C:"
      	FcgidInitialEnv TEMP "C:/Xampp/tmp"
      	FcgidInitialEnv TMP "C:/Xampp/tmp"
      	FcgidInitialEnv windir "C:/WINDOWS"
      	FcgidIOTimeout 64
      	FcgidConnectTimeout 16
      	FcgidMaxRequestsPerProcess 1000 
      	FcgidMaxProcesses 3
      	FcgidMaxRequestLen 8131072
      	# Location php.ini:
      	FcgidInitialEnv PHPRC "C:/Xampp/php5.5.12-nts"
      	FcgidInitialEnv PHP_FCGI_MAX_REQUESTS 1000
      	<Files ~ "\.php$">
      		Options Indexes FollowSymLinks ExecCGI 
      		AddHandler fcgid-script .php
      		FcgidWrapper "C:/Xampp/php5.5.12-nts/php-cgi.exe" .php
      <IfModule mime_module>
          AddType application/x-httpd-php .php
          AddType application/x-httpd-php .php3
  5. Create a new php configuration file by copying the file at “C:\Xampp\php5.5.12-nts\php.ini-development” to “C:\Xampp\php5.5.12-nts\php.ini”.
  6. Finally, restart Apache server and PHP should be running in FastCGI mode. Visit and check that ServerAPI is CGI/FastCGI to confirm.

Steps to Enable Zend OPcache

  1. Edit the php configuration file at “C:\Xampp\php5.5.12-nts\php.ini”.
    • Locate the section [opcache].
    • Add this line before the section:
    • Uncomment the configuration lines in the section:
      ; Determines if Zend OPCache is enabled
      ; Determines if Zend OPCache is enabled for the CLI version of PHP
      ; The OPcache shared memory storage size.
      ; The amount of memory for interned strings in Mbytes.
      ; The maximum number of keys (scripts) in the OPcache hash table.
      ; Only numbers between 200 and 100000 are allowed.
      ; The maximum percentage of "wasted" memory until a restart is scheduled.
      ; When this directive is enabled, the OPcache appends the current working
      ; directory to the script key, thus eliminating possible collisions between
      ; files with the same name (basename). Disabling the directive improves
      ; performance, but may break existing applications.
      ; When disabled, you must reset the OPcache manually or restart the
      ; webserver for changes to the filesystem to take effect.
      ; How often (in seconds) to check file timestamps for changes to the shared
      ; memory storage allocation. ("1" means validate once per second, but only
      ; once per request. "0" means always validate)
      ; Enables or disables file search in include_path optimization
      ; If disabled, all PHPDoc comments are dropped from the code to reduce the
      ; size of the optimized code.
      ; If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments"
      ; may be always stored (save_comments=1), but not loaded by applications
      ; that don't need them anyway.
      ; If enabled, a fast shutdown sequence is used for the accelerated code
      ; Allow file existence override (file_exists, etc.) performance feature.
      ; A bitmask, where each bit enables or disables the appropriate OPcache
      ; passes
  2. Finally, restart Apache web server. Visit and search for Opcache. If it is found, then you have successfully enabled opcode caching!
