If you have installed php before installing apache, access any php file and return the source code.
If I install apache first and then install php, configure
LoadModule php5_module/usr/local/Cellar/php53/5.3.29/libexec/apache2/libphp5.so

AddType application/x-httpd-php .phpAddType application/x-httpd-php-source .phps
   
        DirectoryIndex index.html index.php
   

You can happily run php.
What's going on ??
PS: after running, phpinfo displays Server API Apache 2.0 Handler
I don't know if it has anything to do with this ??
It feels amazing ~
