Previous Comments: ------------------------------------------------------------------------ [2002-03-18 02:27:56] derick@php.net Works for me with 4.3.0-dev too. Derick ------------------------------------------------------------------------ [2002-03-17 22:50:51] philip@php.net This bug was fixed by Jeroen on Oct 5, 2001 as stated under bug #13567. Assigning to self for a little more testing, this change took place in 4.2.0 and will be documented as such. Good thing in PHP everyone uses == :)) <?php $return = array_search('sorry', array('foo','bar')); print '$return is type: '. gettype($return) ."\n"; if ($return === false) print "\$return === false\n"; if ($return === NULL) print "\$return === NULL\n"; /* X-Powered-By: PHP/4.2.1-dev (3-17) $return is type: boolean $return === false X-Powered-By: PHP/4.1.2 $return is type: NULL $return === NULL */ ?> ------------------------------------------------------------------------ [2002-03-17 21:08:16] mccarthy36@earthlink.net I am calling array_search. I expect it to return FALSE if the needle value is not in the haystack (as documented) -- it's not happening. I searched the bug database and found this bug (#13567) reported for v. 4.0.5 and marked as closed, but the bug is still present in 4.1.2. Script that demonstrates the problem: $result = array_search( "M", array( "A", "Z" ) ); if ( $result === false ) { echo "REALLY FALSE"; } else { echo "SOMETHING ELSE"; } I expect the script to output "REALLY FALSE", instead it outputs "SOMETHING ELSE". Thanks. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16130&edit=1
