final public static OAuthProvider::generateToken(int $size
, bool $strong
= false
): string
Parameter-Liste

size
-
The desired token length, in terms of bytes.
-

Setting to true
means /dev/random

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).

implementation.
