HOW TO GET USER INPUT

Implementing using GET method – In page1.php change the method of the form as method=”get”. In page2.php edit $_POST as $_GET. On running the code you will get the output as shown below. Please check the url shown in the output. Values will be displayed in the url.


When to use method="post"? Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
