(PECL OAuth >= 1.0.0)
OAuthProvider::generateToken — Generate a random token
Generates a string of pseudo-random bytes.
The desired token length, in terms of bytes.
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).
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
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.
