base_convert()

Wikimedia\base_convert	(		$input,
			$sourceBase,
			$destBase,
			$pad = 1,
			$lowercase = true,
			$engine = 'auto' )

Convert an arbitrarily-long string from one numeric base to another, optionally zero-padding to a minimum column width.

Supports base 2 through 36; digit values 10-36 are represented as lowercase letters a-z. Input is case-insensitive.

Parameters

string	$input	Input number
int	$sourceBase	Base of the input number
int	$destBase	Desired base of the output
int	$pad	Minimum number of digits in the output (pad with zeroes)
bool	$lowercase	Whether to output in lowercase or uppercase
string	$engine	Either "gmp", "bcmath", "php" or "auto" (default). In the case of "auto", the other engines ("gmp" and "bcmath") are used in the listed order in terms of preference if that PHP extension is actually loaded.

Returns

string|false The output number as a string, or false on error
