Méthodes protégées

Méthode Description
getMinimalBitMask ( integer $toRepresent ) : integer Returns the smallest bit mask of all 1s such that ($toRepresent & mask) = $toRepresent

Method Details

compareStrings() public static méthode

Compare strings
Deprecation:
public static compareStrings ( string $a, string $b ) : boolean
$a string String 1
$b string String 2
Résultat boolean Equal?

getMinimalBitMask() protected static méthode

Returns the smallest bit mask of all 1s such that ($toRepresent & mask) = $toRepresent
protected static getMinimalBitMask ( integer $toRepresent ) : integer
$toRepresent integer must be an integer greater than or equal to 1
Résultat integer

hash() public static méthode

Generate keccak hash for string with salt
Deprecation:
public static hash ( string $str, string $salt = '', boolean $plain = false ) : string
$str string Data
$salt string Salt
$plain boolean Is plain text?
Résultat string

randomBytes() public static méthode

Returns string of pseudo random bytes
public static randomBytes ( integer $len, callable $cb, integer $pri, boolean $hang = false ) : integer
$len integer Length of desired string
$cb callable Callback
$pri integer Priority of EIO operation
$hang boolean If true, we shall use /dev/random instead of /dev/urandom and it may cause a delay
Résultat integer

randomInts() public static méthode

Returns array of pseudo random integers of machine-dependent size
public static randomInts ( integer $numInts, callable $cb, integer $pri, boolean $hang = false ) : integer
$numInts integer Number of integers
$cb callable Callback
$pri integer Priority of EIO operation
$hang boolean If true, we shall use /dev/random instead of /dev/urandom and it may cause a delay
Résultat integer

randomInts32() public static méthode

$pri integer Priority of EIO operation
$hang boolean If true, we shall use /dev/random instead of /dev/urandom and it may cause a delay
Résultat integer

randomString() public static méthode

Returns string of pseudo random characters
public static randomString ( integer $len = null, string $chars = null, callable $cb = null, integer $pri, boolean $hang = false ) : string
$len integer Length of desired string
$chars string String of allowed characters
$cb callable Callback
$pri integer Priority of EIO operation
$hang boolean If true, we shall use /dev/random instead of /dev/urandom and it may cause a delay
Résultat string
