ID: 54209 Updated by: ahar...@php.net Reported by: phristen at yahoo dot com Summary: Inconsistent array index behaviour -Status: Open +Status: Duplicate Type: Bug Package: Scripting Engine problem Operating System: * PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: Duplicate of numerous bugs, including bug #45959. In short, this is expected behaviour, and is unlikely to be changed, as doing so would cause performance issues within PHP. Previous Comments: ------------------------------------------------------------------------ [2011-03-09 22:25:57] phristen at yahoo dot com Description: ------------ It is well known that PHP casts numeric string indexes to integers, and it is normally impossible to force such indexes to remain strings. For example, the script below will output "integer": $test = array("123" => 1); echo gettype(key($test)); // integer However, it is possible to achieve this if we assign numeric string property to an object (by using the ->{} syntax), and then cast it to array. Not only will the index retain it's string type, but it will also be impossible to access that index with [], which can't be correct behaviour. See attached example. Test script: --------------- <?php $test = new stdClass(); $test->{"123"} = 1; $test = (array)$test; $key = key($test); echo gettype($key); echo "\n"; echo $test[$key]; ?> Expected result: ---------------- integer 1 Actual result: -------------- string PHP Notice: Undefined index: 123 in test.php on line 9 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54209&edit=1
