$_GET

$HTTP_GET_VARS [obsoleta]

$_GET -- $HTTP_GET_VARS [obsoleta] — Variables HTTP GET

Descripción

Una matriz asociativa de variables pasadas al script actual a través del método HTTP GET.

$HTTP_GET_VARS contiene la misma información inicial, pero no es una superglobal. (Note que $HTTP_GET_VARS y $_GET son variables diferentes y que PHP las trata como tal)

Registro de cambios

Versión	Descripción
4.1.0	Se introdujo `$_GET`, haciendo `$HTTP_GET_VARS` obsoleta.

Ejemplos

Example #1 Ejemplo de $_GET


<?php
echo '¡Hola ' . htmlspecialchars($_GET["nombre"]) . '!';
?>

Asumiendo que el usuario ha visitado una dirección del tipo http://example.com/?nombre=Juan

El resultado del ejemplo seria algo similar a:

¡Hola Juan!

Notes

Note: This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. There is no need to do global $variable; to access it within functions or methods.

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.
