Apache2 PHP5 LoadModule problem: Apache won't start

Most of the PHP programmers get this error when installing PHP and Apache:

Apache2 PHP5 LoadModule problem: Apache won't start

The reason why they get this error because they might be using Apache 2.2.x and they added this in their httpd.conf:

LoadModule php5_module C:/php/php5apache2.dll

If you're using Apache 2.2.x, this is the right line to be added in httpd.conf (please take note of the bold font below):

LoadModule php5_module C:/php/php5apache2_2.dll
