$_get Variable

The predefined $_get variables are used to collect values from the form method= "GET".

Information sent from a form with a GET method is visible to anyone (displayed in the browser's address bar) and has a limit on the amount of information sent.

Let's take a visual look at the Fig diagram and see how this demo is implemented:

The first step:

Client.html (only one line of code):

<a href= "Server.php?name=iwanghang&age=18" >server</a>

Step Two:

server.php:

<?php    var_dump ($_get);//Print Result: Array (2) {["Name"]=> string (9) "Iwanghang" ["Age"]=> string (2) "}"}    echo "<br>";    echo $_get[' name ']. " <br> "; Print Result: Iwanghang    echo $_get[' age ']. " <br> "; Printed results: 18

Form submission:

server.php:

<!--<a href= "server.php?name=iwanghang&age=18" >server</a>--><!--form form--><form action= "server.php" method= "get" >    username:<input type= "text" name= "name" ><br>    age:< Input type= "text" name= "age" ><br>    <input type= "Submit" value= "Commit" ></form>
