What is $_REQUEST in PHP?
$_REQUEST
$_REQUEST is a superglobal variable in PHP that contains input from ＄_POST, ＄_GET, and ＄_COOKIE. These correspond to HTTP POST, GET, and Cookies.
Usage
The following example shows how \＄_REQUEST can be used:
<?php// Choosing input typeif ($_SERVER["REQUEST_METHOD"] == "POST") {// Getting data from input$shotname = htmlspecialchars($_REQUEST['shot']);echo $shotname}?>
This example shows how ＄_REQUEST can be used once a request has been made:
- The if statement checks whether it matches the required method. Here, it checks if it is a
POSTrequest. - Then, it gets the data using
＄_REQUEST['shot']. As can be seen,＄_REQUESTacts as an associative array as it uses a key to access data. - Once data is collected, it is converted to HTML, using
htmlspecialchars(), and displayed.
