Class used internally by Diff to actually compute the diffs. The algorithm used here is mostly lifted from the perl module Algorithm::Diff (version 1.06) by Ned Konz, which is available at: http://www.perl.com/CPAN/authors/id/N/NE/NEDKONZ/Algorithm-Diff-1.06.zip More ideas are taken from: http://www.ics.uci.edu/~eppstein/161/960229.html Some ideas (and a bit of code) are from analyze.c, from GNU diffutils-2.7, which can be found at: ftp://gnudist.gnu.org/pub/gnu/diffutils/diffutils-2.7.tar.gz c

public static DiffArray::diffAssocRecursive(array $array1, array $array2) Recursively computes the difference of arrays with additional index check. This is a version of array_diff_assoc() that supports multidimensional arrays. Parameters array $array1: The array to compare from. array $array2: The array to compare to. Return value array Returns an array containing all the values from array1 that are not present in array2. File core/lib/Drupal/Component/Utility/DiffArray.php, line 27 Class
