Basics of LAMP - How it Works?
 
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          ||
      __________                            ___________                      ________

                                                                _________
                                                                /        /
                                                              / MySql  /
                                                              /________/
