Edit report at https://bugs.php.net/bug.php?id=62680&edit=1 ID: 62680 Updated by: kriscraig@php.net Reported by: kriscraig@php.net Summary: Function isset() throws fatal error on set array if non-existent key depth >= 3 -Status: Verified +Status: Wont fix Type: Bug Package: Arrays related Operating System: Linux and Windows PHP Version: 5.3.15 -Assigned To: +Assigned To: kriscraig Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2012-08-25 07:19:48] kriscraig@php.net @Laruence Sorry for the delay; they're keeping me busy up here! Yeah I have no objection. It really sucks but I have to agree. Since it's fixed in 5.4, it really wouldn't be worth tearing into 5.3's guts just to correct this. I'll go ahead and mark it "won't fix" for ya (as I try to think happy thoughts). =) ------------------------------------------------------------------------ [2012-07-31 02:48:17] laruence@php.net I'd like mark this as won't fix for 5.3, fixing this will be a big work IMO, maybe introduce new issues, and 5.3 is quite stable version now. ------------------------------------------------------------------------ [2012-07-30 18:32:12] kriscraig@php.net Woops, drop the word "ternary" from the description/title. =) ------------------------------------------------------------------------ [2012-07-30 18:30:31] kriscraig@php.net Oh and here's the test case: --TEST-- Test for existence of ternary isset() bug in nested arrays. --DESCRIPTION-- Errors should not be thrown when passing non-set arguments to isset(). --CREDIT-- Kris Craig <kriscraig@php.net> --FILE-- <?php $arr = array( "key" => "", "key2" => array( "subkey" => array( "supersubkey" => array( "superdupersubkey" => "Hello." ) ) ), "key3" => array( "subkey" => array( "supersubkey" => "Hello." ) ) ); if ( isset( $arr["key"]["non_existant_key"] ) ) { print "Arroooo?"; } print "DEBUG #1.<br />\r\n"; $out = ( isset( $arr["key"]["non_existent_key"] ) ?

Is this a won't fix then since it's not in 5.4? Or is this still something we'd want to correct?
