How to Manually Install PHP 7.4 for Windows Server 2019

Motivation:

To understand how PHP works with IIS in order to be able to update PHP to any version to address compatibility or security issues.

Using a tool to install PHP for IIS, for example Microsoft Web Platform Installer 5.0 https://www.microsoft.com/web/downloads/platform.aspx, restricts us from using only versions supported by the tool.

Solution:

  • Install CGI for IIS.
  • Download VC15 x86 Non Thread Safe package here or under PHP 7.4 section from http://windows.php.net/download/
  • Extract the ZIP file to the C:\Program Files (x86)\php-7.4.9-nts-Win32-vc15-x86 folder.
  • Rename the php-.ini-development file to php.ini.
  • Open the php.ini file and add the following line at the end of the file.
extension=php_wincache.dll
  • Uncomment the following lines
fastcgi.impersonate = 1;

cgi.fix_pathinfo=1;
cgi.force_redirect = 1 (and change the value to 0, i.e. cgi.force_redirect = 0)

extension_dir = "C:\Program Files (x86)\php-7.4.9-nts-Win32-vc15-x86\ext"

extension=php_curl.dll
extension=php_fileinfo.dll
extension=php_mbstring.dll
extension=php_exif.dll
extension=php_mysqli.dll
extension=php_pdo_mysql.dll
extension=php_openssl.dll

error_log = "C:\Program Files (x86)\php-7.4.9-nts-Win32-vc15-x86\php_errors.log"

error_log = syslog
  • A sample php.ini file can be download here.
  • Add C:\Program Files (x86)\php-7.4.9-nts-Win32-vc15-x86 to System Path.
  • Download x86 package of WinCache 2.0 for PHP 7.4 here or from https://sourceforge.net/projects/wincache/.
  • Extract and copy the php_wincache.dll file to C:\Program Files (x86)\php-7.4.9-nts-Win32-vc15-x86\ext
    folder.
  • Open IIS, click on Server name, double click on Handler Mappings, click on Add Module Mapping, and enter below information
Request path = *.php
Module = FastCgiModule
Executable = "C:\Program Files (x86)\php-7.4.9-nts-Win32-vc15-x86\php-cgi.exe"
Name = PHP 7.4
Request Restrictions = File or folder

Open a Command Prompt, execute below command and ensure that NO WARNINGS APPEAR.

php -version
  • Create phpinfo.php file with below content in the website folder and test the result.
<?php
phpinfo();
?>
