Doc #61507 [Com]: Incompatibilty when using isset() on a string with a string key as offset

Edit report at https://bugs.php.net/bug.php?id=61507&edit=1 ID: 61507 Comment by: mkwan at corp dot oodle dot com Reported by: joffery at ne2000 dot nl Summary: Incompatibilty when using isset() on a string with a string key as offset Status: Closed Type: Documentation Problem Package: Documentation problem Operating System: ANY PHP Version: 5.4.0 Assigned To: yohgaki Block user comment: N Private report: N New Comment: Is the implication that using a string key offset is undefined behavior, so it doesn't matter what PHP does? Because, if the _defined_ behavior is to return false, then it is inconsistent with other contexts. $ php -r '$str = "str"; var_dump(isset($str["x"]));' bool(false) $ php -r '$str = "str"; var_dump($str["x"]);' string(1) "s" How can something not be set but also have a value?

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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
