ID: 51015 User updated by: nat at search dot ch Reported By: nat at search dot ch Status: Bogus Bug Type: *General Issues Operating System: Linux #1 SMP 2009-08-15 17:53:59 PHP Version: 5.3.1 New Comment:
$choices is a variable of a new kind. It is no: - Boolean - Integer - Floating point number - String - Array - Object It is an inconsequence with the rest of php. I think this case should be considered in future versions. Previous Comments: ------------------------------------------------------------------------ [2010-02-12 16:45:44] [email protected] RTFM: http://php.net/array#language.types.array.casting "If an object is converted to an array, the result is an array whose elements are the object's properties. The keys are the member variable names, with a few notable exceptions: integer properties are unaccessible.." And you could also access those directly without casting anyway, like this: var_dump($model->choices->{1}); ------------------------------------------------------------------------ [2010-02-11 13:57:10] nat at search dot ch Description: ------------ In an associative array with number as text keys, the keys can not be used to get the values. "Foreach" works. var_dump($choices); // array(2) { ["1"]=> array(2) { [0]=> string(1) "0" [1]=> string(1) "1" } ["0"]=> array(2) { [0]=> string(1) "0" [1]=> string(1) "1" } } var_dump($choices['1']); // NULL var_dump($choices[1]); // NULL var_dump($choices["1"]); // NULL var_dump($choices->{1}); // NULL var_dump($choices->{'1'});//NULL var_dump($choices['0']); //NULL var_dump($choices[0]); //NULL foreach ($choices as $k => $v) { var_dump($k, $v); } // string(1) "1" array(2) { [0]=> string(1) "0" [1]=> string(1) "1" } // string(1) "0" array(2) { [0]=> string(1) "0" [1]=> string(1) "1" } Reproduce code: --------------- $db_data_model='{"events":{"1":"film","0":"avatar"},"times":{"0":"2010-10-09 08:00","2":"2010-10-09 11:00","3":"2010-09-09"},"choices":{"1":["0","1"],"0":["0","1"]}}'; $model = json_decode($db_data_model); $choices = (array)$model->choices; var_dump($choices); var_dump($choices['1']); // NULL var_dump($choices[1]); // NULL var_dump($choices->{1}); // NULL var_dump($choices->{'1'});//NULL foreach ($choices as $k => $v) { var_dump($k, $v); } Expected result: ---------------- var_dump($choices['1']); // array(2) { [0]=> string(1) "0" [1]=> string(1) "1" } var_dump($choices['0']); // array(2) { [0]=> string(1) "0" [1]=> string(1) "1" } Actual result: -------------- var_dump($choices['1']); // NULL var_dump($choices['0']); // NULL ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=51015&edit=1
