An E_NOTICE will also be thrown if attempting to access a non-existent numerical key in a string, but not if attempting to access a non-existent non-numerical key. If an E_NOTICE is displayed under one circumstance for an index not existing it seems that it should be displayed under all circumstances when an index doesn't exist. Reproduce code: --------------- error_reporting(E_ALL | E_STRICT); $dummyArray = array(); // this will throw an E_NOTICE $error = $dummyArray['doesNotExist']; $dummyArray = true; // this will not throw an E_NOTICE $noError = $dummyArray['doesNotExist']; $dummyArray = 'string'; // this will not throw an E_NOTICE $noError = $dummyArray['doesNotExist']; // but this will throw an E_NOTICE $error = $dummaryArray['100']; Expected result: ---------------- Notice: Undefined index: doesNotExist Notice: Undefined index: doesNotExist Notice: Undefined index: doesNotExist Notice: Uninitialized string offset: 100 Actual result: -------------- Notice: Undefined index: doesNotExist < nothing when attempting to access a non-existent key of a bool > < nothing when attempting to access a non-existent key of a string > Notice: Uninitialized string offset: 100 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=45290&edit=1
