$_GET

$HTTP_GET_VARS [Obsolète]

$_GET -- $HTTP_GET_VARS [Obsolète]Variables HTTP GET

Description

Un tableau associatif des valeurs passées au script courant via le protocole HTTP et la méthode GET.

$HTTP_GET_VARS contient les mêmes informations, mais n'est pas superglobale. (Notez que $HTTP_GET_VARS et $_GET sont des variables différentes et que PHP les traite comme telles.)

Historique

Version Description
4.1.0 Introduction de $_GET, rendant obsolète $HTTP_GET_VARS.

Exemples

Exemple #1 Exemple avec $_GET

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

En assumant que l'utilisateur a entré http://example.com/?name=Yannick

L'exemple ci-dessus va afficher quelque chose de similaire à :

Bonjour Yannick !

Notes

Note: Ceci est une 'superglobale', ou variable globale automatique. Cela signifie simplement que cette variable est disponible dans tous les contextes du script. Il n'est pas nécessaire de faire global $variable; pour y accéder dans les fonctions ou les méthodes.

This code is really useful for reproducing the values in the $_GET variable, and attaching that to a $_SERVER['PHP_SELF'] value when building the action value of a form tag, so that you don't lose any other values that could have been passed:

foreach ($_GET as $key => $value) {
            if ($key != "C") {  // ignore this particular $_GET value
                $querystring .= $key."=".$value;
            }
}

Use this code if you want to retrieve your queries no matter what method is used. Hope it helps.

<?php

$name = trim ((!empty($_POST['name'])) ? $_POST['name'] : $_GET['name'] );

if (
strlen ($name) < 1)
{
    echo
"Please enter your name";
} else {
   
printf ("Hello <b>%s</b><br>", $name);
   
printf ("Bonjour <b>%s</b><br>", $name);
   
printf ("Hallo <b>%s</b><br>", $name);
   
printf ("Ciao <b>%s</b><br>", $name);
   
printf ("Hola <b>%s</b><br>", $name);
}

Note that named anchors are not part of the query string and are never submitted by the browser to the server.

Eg.
http://www.xyz-abc.kz/index.php?title=apocalypse.php#doom

echo $_GET['title'];

// returns "apocalypse.php" and NOT "apocalypse.php#doom"

you would be better off treating the named anchor as another query string variable like so:
http://www.xyz-abc.kz/index.php?title=apocalypse.php&na=doom

...and then retrieve it using something like this:
$url = $_GET['title']."#".$_GET['na'];

Hope this helps someone...

Note:
If nothing is set in the address bar, the value of $_GET['n'] will be NULL, not ""(empty string) or false.
