Detailed Description

Constructor & Destructor Documentation

__construct()

MappedDiff::__construct	(		$from_lines,
			$to_lines,
			$mapped_from_lines,
			$mapped_to_lines
	)

Constructor.

Computes diff between sequences of strings.

This can be used to compute things like case-insensitve diffs, or diffs which ignore changes in white-space.

Parameters

$from_lines	array An array of strings. (Typically these are lines from a file.)
$to_lines	array An array of strings.
$mapped_from_lines	array This array should have the same size number of elements as $from_lines. The elements in $mapped_from_lines and $mapped_to_lines are what is actually compared when computing the diff.
$mapped_to_lines	array This array should have the same number of elements as $to_lines.
