How to run PHP as CGI with Suexec

Running PHP as CGI

  1. Jaishree
    PhP is a server side script that is loaded into a server and generates the pages. CGI is utilized by replacing a SSI directive tag in HTML. When a page is loaded in the browser the server reads that directive and run the script file, which is replaced by given tag. If you are running PHP as CGI it means that you are telling your server about the destination of your PHP file and server executes that file each time when this page is requested. When every time a page is delivered in the browser, PHP reads the php.ini and configure its settings. Running php as CGI is more secure than DOS, because server controls the access to the coded library.

    Steps to Run PHP as CGI:

    Step 1: If you want to run php as CGI you need to configure the httd.conf first.
