How To Change What Version of PHP Apache2 Uses?

Question

Ubuntu 10.04, MySQL 5.1, Apache 2.2, and PHP 5.2/5.3:

I just discovered that I am using the wrong version of PHP for a CRM application. Once I figured out how to make a simple phpinfo() script to tell me what Apache2 is using, I tried changing the php.ini such that my webserver would use the PHP I want. Well, this is my problem. Not sure how to do that.

I compiled the version of PHP I want to /etc here:

/etc/php-5.2.8/

Inside this, there was a php.ini-recommended file that I made some changes to and renamed to php.ini so PHP would use it. But when I opened my browser and cleared my history and went to the http://localhost<CRM dir>/install.php address, the wizard still says I'm not usign the correct version of PHP.

Based on this post what do I have to do to change the version of PHP that shows up after I run my test.php script? In other words, phpinfo() says I'm running PHP 5.3.2, but I want to change it to my compiled 5.2.8 version located in /etc.

Answer 1

depending on your server, you should be looking in apache, not php.

(For RHEL/CentOS) look in : /etc/httpd/conf.d/php.ini

  1 #
  2 # PHP is an HTML-embedded scripting language which attempts to make it
  3 # easy for developers to write dynamically generated webpages.
  4 #
  5
  6 LoadModule php5_module modules/libphp5.so
  7
  8 #
  9 # Cause the PHP interpreter to handle files with a .php extension.
 10 #
 11 AddHandler php5-script .php
 12 AddType text/html .php

You'll see that your PHP module is modules/libphp5.so.

AddHandler php5-script .php tells apache to run PHP on any file with the extension .php.

If your using a RPM based OS its probably easier to uninstall (assuming you can do that) the current verison of PHP, and reinstall the verison you are looking for.

rpm -qa | grep php

will show you what verison of PHP is currently installed.
