note 37664 added to function.usort

I have a class with a bunch of functions that work with an SQL database. I am working with calendar dates that occur more than once (like once a week for 2 months), so I have to generate the date in php after the SQL. But I wanted to sort the events based on the date, so I tried using usort, but was unable to get it to work, because it didn't think that my sorting function was defined (even though it was in the same class). I have a separate class to store the data, that has a variable called Start which is a PHP date object. So here is how I got it to work. First I created a temporary function, that returned the value of a string comparison of the timestamps for the dates. Then I used that temporary function for the usort. Enjoy. $tempfunction = create_function('$event1,$event2', 'return strcmp($event1->Start[0],$event2->Start[0]);'); usort($data,$tempfunction); ---- Manual Page -- http://www.php.net/manual/en/function.usort.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+37664 Delete -- http://master.php.net/manage/user-notes.php?action=delete+37664&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+37664&report=yes Search -- http://master.php.net/manage/user-notes.php
