How To: Install PHP to Apache web server

After install apache 2.2 on centos , there is no PHP Module built-in, You have to do the same thing like installing apache, Download the source file , compile and put the modules to the folder that will be picked up by apache. Here is the rough steps,

• Download and extract the tarball from php.net, http://us.php.net/get/php-5.3.5.tar.gz/from/this/mirror
• tar –zxvf php-5.3.5.tar.gz
• go into the uncompressed php folder and run the config
• ./configure –with-apxs2=/opt/apache/bin/apxs –-prefix=/opt/php
• if needed, yum install libevent-devel libxml2-devel
• Compile and Test
• make && make test
• Install the module to the modules folder
• make install
• this will automatically upate apache’s conf/httpd.conf with
  LoadModule php5_module        modules/libphp5.so
  Add the handler of php manully.
  AddType application/x-httpd-php .php
• restart the apache daemon

TO test, create a single line file to htdocs/test.php

<?php phpinfo();?>

when access that url , you will get the information of php settings, now you are good to go.
