OAuthProvider::generateToken

(PECL OAuth >= 1.0.0)

OAuthProvider::generateTokenGenerate a random token

Description

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

Generates a string of pseudo-random bytes.

Parameters

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.

Return Values

The generated token, as a string of bytes.

Errors/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).

Examples

Example #1 OAuthProvider::generateToken() example

<?php
$p 
= new OAuthProvider();

$t $p->generateToken(4);

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

?>

The above example will output something similar to:

4
b6a82c27

Notes

Note:

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