Edit report at https://bugs.php.net/bug.php?id=65942&edit=1 ID: 65942 Updated by: bwoebi@php.net Reported by: gontijo dot douglas at gmail dot com Summary: PHP Notice is fired if the specified $index does not exists -Status: Not a bug +Status: Open Type: Documentation Problem Package: Documentation problem PHP Version: Irrelevant Block user comment: N Private report: N New Comment: That actually is a documentation problem: the docs don't state that (new ArrayObject([…]))->offsetGet('undefinedIndex'); can raise a notice upon not found index. Previous Comments: ------------------------------------------------------------------------ [2013-10-22 08:32:23] krakjoe@php.net This is expected behaviour; isset/offsetExists does not request a read of the element requested, only checks for it's presence. It would not be useful for isset/offsetExists to raise a warning; it is however expected that if you read from a non-existent element a warning will be raised, because you have not checked for the presence of the element but requested the elements data, which doesn't exist. ------------------------------------------------------------------------ [2013-10-22 01:11:16] gontijo dot douglas at gmail dot com Description: ------------ --- From manual page: http://www.php.net/arrayobject.offsetget#refsect1-arrayobject.offsetget-returnvalues --- It'll fire a PHP Notice if the specified $index does not exists Test script: --------------- <?php // from http://www.php.net/manual/en/arrayobject.offsetget.php#example-3971 $arrayobj = new ArrayObject(array('zero', 7, 'example'=>'e.g.')); var_dump($arrayobj->offsetGet(1)); var_dump($arrayobj->offsetGet('example')); var_dump($arrayobj->offsetExists('notfound')); // added by me var_dump($arrayobj->offsetGet('notfound')); //shouldn't return null silently? Expected result: ---------------- int(7) string(4) "e.g." bool(false) NULL Actual result: -------------- int(7) string(4) "e.g." bool(false) Notice: Undefined index: notfound in test.php on line 8 NULL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65942&edit=1
