$_POST

(PHP 4 >= 4.1.0, PHP 5, PHP 7, PHP 8)

$_POST — Form data from HTTP POST requests

Descrizione

An associative array of variables passed to the current script via the HTTP POST method when using application/x-www-form-urlencoded or multipart/form-data as the HTTP Content-Type in the request.

Esempi

Example #1 $_POST example

<?php
echo 'Hello ' . htmlspecialchars($_POST["name"]) . '!';
?>

Assuming the user sent a POST request with name=Hannes in the body.

Il precedente esempio visualizzerà qualcosa simile a:

Hello Hannes!

Note

Nota:

Questa è una variabile 'superglobale', o automaticamente global. Ciò semplicemente significa che è visibile in tutti gli ambiti in uno script. Non è necessario dichiararla come global $variable; per accedervi da funzioni o metodi.

Nota: To read POST data sent with other content types (e.g. application/json or application/xml) php://input must be used. Unlike $_POST, which only works with application/x-www-form-urlencoded and multipart/form-data, php://input provides direct access to the raw data from the body of the request.
