Why am I getting errors when starting Apache server to load PHP as a module with php5apache2.dll?

httpd.exe: Syntax error on line 116 of C:/Program Files
/Apache Software Foundation/Apache2.2/conf/httpd.conf:
Cannot load C:/Program Files/php-5.2.0-Win32
/php5apache2.dll into server: The specified module could
not be found.

This tutorial explains why and helps you to resolve the issue.

1. Go to the PHP installation directory: C:/Program Files/php-5.2.0-Win32. You will see two files:

11/02/2006  12:41 PM   36,925 php5apache2.dll
11/02/2006  12:41 PM   36,927 php5apache2_2.dll

2. PHP installation guide tells you to use php5apache2.dll. But that's wrong. php5apache2.dll is not compatible with Apache 2.2 on Microsoft Windows. You should use php5apache2_2.dll.

3. Open Apache server configuration file again and change the LoadModule statement as:

LoadModule php5_module "C:/Program Files/php-5.2.0-Win32/php5apache2_2.dll"
PHPIniDir "C:/Program Files/php-5.2.0-Win32"
...
<IfModule mime_module>
...    
    AddType application/x-httpd-php .php 
</IfModule>

4. Start Apache server again. You will no problem now.
