`62`	`64`	The ``nextBytes()`` method returns a binary string which may contain the
`63`		- ``\0`` character. This can causetroubles inlots of common scenarios, such
	`65`	+ ``\0`` character. This can causetrouble inseveral common scenarios, such
`64`	`66`	`as storing this value in a database or including it as part of the URL. The`
`65`	`67`	solution is to hash the value returned by ``nextBytes()`` (to do that, you
`66`	`68`	can use a simple ``md5()`` PHP function).
