A patch is here: http://marcus-boerger.de/php/ext/ze2/ze2-ifsetor-20040416-4.diff.txt Syntax: ifsetor( <var> [, <exp> ]) Semantic: check whether variable <var> exists and return it. If it not exists evaluate expression <exp> which defaults to NULL and return that value instead. Comment: <var> may also be an array subscription of any depth. ------------------------------------------------------------------------ [2004-04-26 15:18:52] info at gramba dot tv Description: ------------ $a = 'asdf'; echo is_array($a['foo']['asdf']); is completly invalid, unfortunatly many applications deal with the fact that some offsets simply "may" not exist. workaround would be if (isset($a['foo']['asdf']) && is_array($a['foo']['asdf']) { .... but this would bloat the code a lot Reproduce code: --------------- // /* E_ERROR Invalid offset */ $a = 'asdf'; echo is_array($a['foo']['asdf']); Expected result: ---------------- an E_WARNING instead of E_ERROR which is suppressable Actual result: -------------- E_ERROR ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=28156&edit=1
