I wanted to install php on my dedicated Apache Server version 2.2 on Linux System.
So please suggest me some link where I found accurate documentation or steps for installation with all configuration and setting.
Depending on the Linux-Distribution you use, you can use apt-get as package manager. Then all you have to do is to install you php-package with it.
Example for Debian
sudo apt-get install php5
(if you are logged in as root, you don't need sudo)
You also found such information on php.net:
http://www.php.net/manual/en/install.unix.debian.php
You need to add the following lines to httpd.conf
ScriptAlias /php/" c:/path-to-php-dir/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php.exe"
Then restart Apache and it should interpret php files correctly.
For more information on installing Apache with php look at the following manual page: http://www.php.net/manual/en/install.apache.php
