From: Operating system: Linux / Windows PHP version: 5.3.4 Package: SPL related Bug Type: Bug Bug description:property_exists incorrect on ArrayObject null and 0 values
Description: ------------ Calling property_exists() on an ArrayObject gives a false result on when the value is a false value. This is not in compliance with the description of property_exists(). I tried this on PHP 5.3.2 and 5.3.3 under both Linux + Apache and Windows + IIS. Test script: --------------- $a = array('a' => 1, 'b'=> true, 'c' => 0, 'd' => null, 'e' => false, 'f' => array()); $o = new ArrayObject($a, ArrayObject::ARRAY_AS_PROPS); foreach ($a as $key => $value) { echo $key . ': ' . (is_null($value) ? 'null' : $value) . ' array_key_exists: ' . (array_key_exists($key, $a) ? 'true' : 'false') . ' property_exists: ' . (property_exists($o, $key) ? 'true' : 'false'); } Expected result: ---------------- a: 1 array_key_exists: true property_exists: true b: 1 array_key_exists: true property_exists: true c: 0 array_key_exists: true property_exists: true d: null array_key_exists: true property_exists: true e: array_key_exists: true property_exists: true f: Array array_key_exists: true property_exists: true Actual result: -------------- a: 1 array_key_exists: true property_exists: true b: 1 array_key_exists: true property_exists: true c: 0 array_key_exists: true property_exists: false d: null array_key_exists: true property_exists: false e: array_key_exists: true property_exists: false f: Array array_key_exists: true property_exists: false -- Edit bug report at http://bugs.php.net/bug.php?id=53515&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53515&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53515&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53515&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53515&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53515&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53515&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53515&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53515&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53515&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53515&r=support Expected behavior: http://bugs.php.net/fix.php?id=53515&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53515&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53515&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53515&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53515&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53515&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53515&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53515&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53515&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53515&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53515&r=mysqlcfg
