$_GETHTTP GET variables


An associative array of variables passed to the current script via the URL parameters (aka. query string). Note that the array is not only populated for GET requests, but rather for all requests with a query string.


Example #1 $_GET example

echo 'Hello ' htmlspecialchars($_GET["name"]) . '!';

Assuming the user entered http://example.com/?name=Hannes

Il precedente esempio visualizzerà qualcosa simile a:

Hello Hannes!



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.


The GET variables are passed through urldecode().

// It is important to sanitize
// input! Otherwise, a bad actor
// could enter '<script src="evilscript.js"></script>'
// in a URL parameter. Assuming you echo it, this
// would inject scripts in an XSS attack.
// The solution:
$NAME = $_GET['NAME'];
// Bad:
echo $NAME;
// that one is vulnerable to XSS
// Good:
echo htmlspecialchars($NAME);
// Sanitizes input thoroughly.
