The following instructions will help you install a PHP module for the Apache web server included in MacOS X using the MacOS GUI. This version includes MySQL, PostgreSQL, and iODBC database support, cURL, GD, PDFLib, LDAP, and more. These instructions are graciously provided by » Marc Liyanage.
Be sure you know what you're doing before advancing beyond this point! You can cause irreparable harm to your Apache installation otherwise.
Note:
These instructions will only work with the original Apache web server as shipped by Apple. If you re-built or upgraded your Apache, you will have to build your own PHP module.
To install:
http://www2.entropy.ch/download/entropy-php-5.2.4-1.tar.gz
wget
http://www2.entropy.ch/download/entropy-php-5.2.4-1-apache2.tar.gz
That's all! PHP should now be up and running. You can test it by dropping a file named test.php into your Sites folder in your home directory. Into that file, write this line: <?php phpinfo() ?>.
Now open up 127.0.0.1/~your_username/test.php in your web browser. You should see a status table with information about the PHP module.
