public 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-insensitive 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.
