Previous Comments: ------------------------------------------------------------------------ [2012-03-31 07:22:42] stas@php.net String offset must be a number. ------------------------------------------------------------------------ [2012-03-31 02:55:59] yohgaki@php.net Someone who remember the conclusion of var_dump(isset($str["x"]["x"]) could write comment? I'm not sure how $str['x'] is treated now. If it's doc problem, I'll fix the doc. ------------------------------------------------------------------------ [2012-03-31 02:08:46] yohgaki@php.net Changed bug type from "Doc" to "Bug". Changed Package from "string related" to "scripting engine problem". I think this should be fixed before 5.4.1. ------------------------------------------------------------------------ [2012-03-26 16:37:53] yohgaki@php.net It does. This should be addressed. ------------------------------------------------------------------------ [2012-03-26 10:18:34] joffery at ne2000 dot nl Description: ------------ Incompatibility when using isset() on a string with a string key as offset. Probably an effect of the change "Simplified string offset reading. $str[1][0] is now a legal construct.". Current implementation seems correct although this is an incompatibility in previous versions and should be documented. A previous bug (#37727) noted that behavior before 5.4 was incorrect but was filed as 'not a bug'. Test script: --------------- $ php -r '$str = "str"; var_dump(isset($str["x"]));' Expected result: ---------------- bool(false) Actual result: -------------- PHP 5.3.9: bool(true) PHP 5.4.0: bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61507&edit=1
