GET Array in PHP

The $_GET Array in PHP

Before learning this array you might want to learn the HTTP GET and POST methods in the HTML section of this website.

The forms or any parameter passed to a PHP page with GET method can be retrieved in the PHP page using the inbuilt array $_GET[]. You can retrieve the array values using by using the names of the parameters.Hence $_GET Arrays are associative in nature.

The following is the syntax of a get array.

$user = $_GET["userid"];

An example has been given in the next section which displays a webform with two fields. The form is submitted to the same page. The script displays the parameters submitted using the GET method. A form is submitted using the GET method when the "method" attribute of the form is set to GET or this attribute has not been set at all.
