From: miloslav dot hula at gmail dot com Operating system: PHP version: Irrelevant Package: Scripting Engine problem Bug Type: Bug Bug description:Integer as object property. Malformed array. Description: ------------ When integer used as object's property name, conversion to array by (array) makes normally integer array keys as string. In result, isset() and array_key_exists() doesn't work on malformed array. Test script: --------------- <?php # available on http://3v4l.org/ambbi class ArrayHash extends \stdClass { public static function from(array $arr) { $obj = new static; foreach ($arr as $key => $value) { $obj->$key = $value; } return $obj; } } $one = array('abcdef' => 'xxx', '102787' => 'yyy'); $two = (array) ArrayHash::from($one); echo "# One\n"; var_dump($one); var_dump(isset($one['abcdef'])); var_dump(array_key_exists('abcdef', $one)); var_dump(isset($one[102787])); var_dump(array_key_exists(102787, $one)); var_dump(isset($one['102787'])); var_dump(array_key_exists('102787', $one)); echo "\n\n"; echo "# Two\n"; var_dump($two); var_dump(isset($two['abcdef'])); var_dump(array_key_exists('abcdef', $two)); var_dump(isset($two[102787])); var_dump(array_key_exists(102787, $two)); var_dump(isset($two['102787'])); var_dump(array_key_exists('102787', $two)); echo "\n\n"; Expected result: ---------------- # One array(2) { ["abcdef"]=> string(3) "xxx" [102787]=> string(3) "yyy" } bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) # Two array(2) { ["abcdef"]=> string(3) "xxx" ["102787"]=> string(3) "yyy" } bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) Actual result: -------------- # One array(2) { ["abcdef"]=> string(3) "xxx" [102787]=> string(3) "yyy" } bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) # Two array(2) { ["abcdef"]=> string(3) "xxx" ["102787"]=> string(3) "yyy" } bool(true) bool(true) bool(false) bool(false) bool(false) bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=69799&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69799&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69799&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69799&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69799&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69799&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69799&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69799&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69799&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69799&r=support Expected behavior: https://bugs.php.net/fix.php?id=69799&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69799&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69799&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69799&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69799&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69799&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69799&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69799&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69799&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69799&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69799&r=mysqlcfg
