How To Use Query String In PHP

• Query string is a part of state management in web technologies.
• Query string is used to pass the same data between website pages through hyperlinks.
• Query string value is stored/passed in browser’s address bar or url bar. Later you can get and use these stored values in your PHP web page through $_GET[] super global array.

Example: index page

$site_name = "TutorialsTown";
  $site_url = "tutorialstown.com";
  $about = "programing tutorials";
  echo " Go to page-2 ";

Example: page-2

Page-2

Website name : echo $_GET['site_name']; 
Url : echo $_GET['site_url']; 
About : echo $_GET['about'];
