    LAMP is acronym for Linux , Apache , MySql , PHP/Perl/Python(CGI)..Its a solution stack of opensource programmes and its a platform Wherein each component plays a specific and important role..

    Components


    • Linux - Linux Provides the basic Operating System and Environments
    • Apache - Apache replies to HTTP Requests or passes them to PHP interpretter..
    • MySQL - It serves as a data storage functionality
    • PHP - PHP interpreter parses PHP Code and executes..

    How it works



    When user requests for a page like :-

    http://localhost/index.php

    The request is received by the Operating System I.e Linux and then the request is handed over to apache..

    Apache handling the request check if the url requested is a PHP or a CGI page.. If yes it hands over the request to the PHP interpreter.. Now it replies with the requested resource eg :- index.html etc..

    The PHP interpreter parses the requested file , executes the PHP Code .. If the code includes database queries the request is handed over to MySQL … Mysql deals with the requests received and executes them...

    Once the script interpreter has completed executing the program it returns the result to the browser..

    The figure below will give a better understanding :-

    Code:
    	 _______________
    	/ Client       /
           / Web-Browser  / 
          /______________/
               ||
    Initiates  || http://go4expert.com/index.php
    request	   ||
           __________			    ___________	               ________
          /		/  Hands over to apache	   /          / ------------->/       /
         / Linux   / =======================> /   Apache / PHP Parsing   /  PHP  /
        /_________/ <------------------------/__________/ <-------------/_______/
    	           HTTP RESPONSE				     ||
    								     ||SQL QUERY
    						                 _________
    								/        /
    							       / MySql  /
     							      /________/	
    Thats all for this article...Stay tuned for more..
