note 45562 added to function.key

While this may go without saying for most of us, it is note-worthy that the value returned by key() when called upon an empty array evaluates equal to the empty string. That is, in the following example: $newArray = array(); if (key($newArray) == "") echo "True"; else echo "False"; "True" is output. Not rocket science, but omitted from the documentation above. ---- Manual Page -- http://www.php.net/manual/en/function.key.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+45562 Delete -- http://master.php.net/manage/user-notes.php?action=delete+45562&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+45562&report=yes Search -- http://master.php.net/manage/user-notes.php
