$_REQUESTÂ is an HTTP Request global variable, which collects data after submitting the HTML form.
$_REQUEST is available in all scopes throughout a script.
$_REQUEST is an associative array.
$_REQUEST are provided to the script via the GET, POST, and COOKIE input mechanisms.
In PHP version 7.0 with the default settings.+, $_REQUEST array does not contain cookies.
For Example:-
<form method=”post” action=”<?php echo $_SERVER[‘PHP_SELF’];?>”>
Name: <input type=”text” name=”name”>
<input type=”submit” value=”Request Method”>
</form>
<?php
if ($_SERVER[“REQUEST_METHOD”] == “POST”) {
$name = $_REQUEST[‘name’];
echo $name;
}
}
?>
Similarly:-
<form method=”get” action=”<?php echo $_SERVER[‘PHP_SELF’];?>”>
Name: <input type=”text” name=”name”>
<input type=”submit” value=”Request Method”>
</form>
<?php
if ($_SERVER[“REQUEST_METHOD”] == “GET”) {
$name = $_REQUEST[‘name’];
echo $name;
}
}
?>
So, $_REQUEST will use $_Get if GET is written for the method and $_REQUEST will use $POST if POST is written in the method.
Hence, The PHP $_REQUEST variable can be used to get the result from form data sent with both the GET and POST methods.
