(PECL OAuth >= 1.0.0)
OAuthProvider::generateToken — Generate a random token
설명
final public static string OAuthProvider::generateToken
( int $size
[, bool $strong = false
] )
인수
-
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.
반환값
The generated token, as a string of bytes.
오류/예외
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).
예제
Example #1 OAuthProvider::generateToken() example
<?php
$p = new OAuthProvider();
$t = $p->generateToken(4);
echo strlen($t), PHP_EOL;
echo bin2hex($t), PHP_EOL;
?>
주의
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.
