static getCallableIdentifier ( callable  $variable )

static

Generates an unique identifier to a callable

Parameters

callable

$variable

Returns

string

static getIP (   $force = false )

static

Gets the External IP using an external service, it is cached

Parameters

bool

$force

default false, force IP check even when cached

Returns

string

static getMachineUniqueId (   $extra = "" )

static

Gets this machine / server instance unique ID Returns a hash, the first 32 characters (or 16 if raw) will be an identifier that won't change frequently. The rest of the hash will change depending on other factors.

Parameters

string

$extra

optional, additional data to identify the machine

Returns

UUID

static getOS (   $recalculate = false )

static

Returns the current Operating System Windows => win MacOS => mac iOS => ios Android => android Linux => Linux BSD => bsd Other => other

Returns

string

static getRandomBytes (   $length = 16,   $secure = true,   $raw = true,   $startEntropy = "", &  $rounds = 0, &  $drop = 0  )

static

This function tries to get all the entropy available in PHP, and distills it to get a good RNG.

Parameters

int	$length	default 16, Number of bytes to generate
bool	$secure	default true, Generate secure distilled bytes, slower
bool	$raw	default true, returns a binary string if true, or an hexadecimal one
string	$startEntropy	default null, adds more initial entropy
int	&$rounds	Will be set to the number of rounds taken
int	&$drop	Will be set to the amount of dropped bytes

Returns

string

static getURL (   $page,   $timeout = 10, array  $extraHeaders = []  )

static

GETs an URL using cURL

Parameters

	$page
int	$timeout	default 10
array	$extraHeaders

Returns

bool|mixed

static hexdump (   $bin )

static

Returns a prettified hexdump

Parameters

string

$bin

Returns

string

static postURL (   $page,   $args,   $timeout = 10, array  $extraHeaders = []  )

static

POSTs data to an URL

Parameters

	$page
array | string	$args
int	$timeout
array	$extraHeaders

Returns

bool|mixed

static printable (   $str )

static

Returns a string that can be printed, replaces non-printable characters

Parameters
