OAuthProvider::generateToken

Generate a random token

Beschreibung

final public static string OAuthProvider::generateToken ( int $size [, bool $strong = false ] )

Generates a string of pseudo-random bytes.

Parameter-Liste

size

The desired token length, in terms of bytes.

strong

Setting to TRUE means /dev/random will be used for entropy, as otherwise the non-blocking /dev/urandom is used. This parameter is ignored on Windows.

Rückgabewerte

The generated token, as a string of bytes.

Fehler/Exceptions

If the strong parameter is TRUE, then an E_WARNING level error will be emitted when the fallback rand implementation is used to fill the remaining random bytes (e.g., when not enough random data was found, initially).

Beispiele

Beispiel #1 OAuthProvider::generateToken example

<?php
$p = new OAuthProvider();

$t = $p->generateToken(4);

echo strlen($t),  PHP_EOL;
echo bin2hex($t), PHP_EOL;

?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

4
b6a82c27

Anmerkungen

Hinweis:

When not enough random data is available to the system, this function will fill the remaining random bytes using the internal PHP rand implementation.
