how to check if php is installed on linux

Apr 22, 2010 | Linux

To check whether your linux-box has PHP installed or not:

  1. From the command-shell run: rpm -qa | grep -i php
  2. this should return something like this:
    php-cli-5.1.6-5.el5
    php-5.1.6-5.el5
    php-common-5.1.6-5.el5
    php-ldap-5.1.6-5.el5

Or, you could run a test.php file within the htdocs dir in Apache:

<HTML>
<HEAD>
<TITLE>PHP Test Page</TITLE>
</HEAD>
<BODY><?php phpinfo() ;?></BODY>
</HTML>

You can also look for the installed php dir and run the ‘info.php’ file.
