PHP 4.0 Bug #9645 Updated: usort, uasort, uksort fail every other time

ID: 9645 User Update by: busterb@mail.utexas.edu Status: Closed Bug Type: Arrays related Description: usort, uasort, uksort fail every other time I tried to produce a small, self-contained example of the problem with uasort, but I had already moved my code away from these routines in favor of an external sort. Sadly, I couldn't reproduce the problem in a smaller context, so it must have just been a bug in my code. If anything, the cmp function is probably wrong, since it returns 0 for the < case.

This is a snippet from a class that fails every other time it is called. var $sort_field; function cmp ($a, $b) { return ($a[$this -> sort_field] > $b[$this -> sort_field]); } function sort_records ($sort_field) { $this -> sort_field = $sort_field; uasort ($this -> record_data, array($this, "cmp")); } --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=9645
