#50423 [Opn->Bgs]: Numerical keys casted as strings in arrays, when converting from object

ID: 50423 Updated by: jani@php.net Reported By: anton at zebooka dot com -Status: Open +Status: Bogus Bug Type: Arrays related Operating System: Ubuntu 9.10 PHP Version: 5.2.11 New Comment: "If an object is converted to an array , the result is an array whose elements are the object 's properties. The keys are the member variable names, with a few notable exceptions: integer properties are unaccessible;" And this is exactly what happens. No bug here. Previous Comments: ------------------------------------------------------------------------ [2009-12-09 09:47:48] johannes@php.net sorry misread it ------------------------------------------------------------------------ [2009-12-09 09:45:17] anton at zebooka dot com Yes, I can't. But I have!!! Look closer. Expected result is, when I convert object with numerially named properties, to get array with int keys. But instead I get an array with string numerical keys ------------------------------------------------------------------------ [2009-12-09 09:41:15] johannes@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php You can\'t have array keys with numeric strings as key. ------------------------------------------------------------------------ [2009-12-09 09:36:10] anton at zebooka dot com Again, if you then do echo $a[0]; you'll get 123 instead of 456. Even if you call arsort($a); the result will be the same - 123. ------------------------------------------------------------------------ [2009-12-09 09:33:43] anton at zebooka dot com Description: ------------ As mentioned in documentation, array items can have either string or int. However keys that are numerical strings are converted to int. This is how to create an array with item, which key is string, while it is a number. Reproduce code: --------------- $a = array(123); $o = (object) $a; $o->{0} = 456; $a = (array) $o; var_dump($a); Expected result: ---------------- array(2) { [0]=> int(456) } Actual result: -------------- array(2) { [0]=> int(123) ["0"]=> int(456) } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50423&edit=1
