Usage
$Text_MappedDiff = new Text_MappedDiff(); $Text_MappedDiff->__construct($from_lines, $to_lines,;
- $from_lines(array) (required)
- An array of strings.
- $to_lines(array) (required)
- An array of strings.
- $mapped_from_lines(array) (required)
- 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) (required)
- This array should have the same number of elements as $to_lines.
