public getRandomBytes ( integer $length ) : string
$length	integer	Number of bytes needed
리턴	string	Random bytes

getRandomString() 공개 메소드

Uses supplied character list for generating the new string. If no character list provided - uses Base64 URL character set.

public getRandomString ( integer $length, string \| null $chars = null ) : string
$length	integer	Desired length of the string
$chars	string \| null	Characters to be chosen from randomly. If not given, the Base64 URL charset will be used.
리턴	string	The random string

strlen() 보호된 메소드

We cannot simply use strlen() for this, because it might be overwritten by the mbstring extension. In this case, strlen() will count the number of *characters* based on the internal encoding. A sequence of bytes might be regarded as a single multibyte character. Use elgg_strlen() to count UTF-characters instead of bytes.

protected strlen ( string $binary_string ) : integer
$binary_string	string	The input string
리턴	integer	The number of bytes From PasswordCompat\binary\_strlen
