OAuthProvider::generateToken — Generate a random token
$size
[, bool $strong = FALSE
] ) : stringGenerates a string of pseudo-random bytes.
sizeThe 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.
The generated token, as a string of bytes.
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).
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
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.
