Member Function Documentation

custom()

ILIAS\Refinery\String\Levenshtein::custom	(	string	$str,
		int	$maximum_distance,
		float	$cost_insertion,
		float	$cost_replacement,
		float	$cost_deletion
	)

Creates an object of the Levenshtein class This class calculates the levenshtein distance with custom parameters for insert, delete, replacement.

Parameters

string	$str	string for distance calculation
int	$maximum_distance	maximum allowed distance, limits the calculation of the Levenshtein distance. A maximum distance of 0 disables the function
float	$cost_insertion	cost for insertion default 1.0
float	$cost_replacement	cost for replacement default 1.0
float	$cost_deletion	cost for deletion default 1.0
