From: n-hatano at infiniteloop dot co dot jp Operating system: PHP version: 5.4.37 Package: Arrays related Bug Type: Bug Bug description:Fail to push to the empty array with the constant value defined in class scope Description: ------------ Failed to push to the empty array with the constant value zero defined in class scope. We were able to push any value using empty square bracket to the array which has initialized in class definition. However, if we use the php 5.4.34 - 5.4.37, 5.5.18 - 5.5.21, the following message has returned and the php fails to push the value. "Warning: Cannot add element to the array as the next element is already occupied in" Test script: --------------- <?php class c1 { const ZERO = 0; const ONE = 1; public static $a1 = array(self::ONE => 'one'); public static $a2 = array(self::ZERO => 'zero'); } $v1 = c1::$a1; $v2 = c1::$a2; $v1[] = 1; $v2[] = 1; var_dump($v1); var_dump($v2); Expected result: ---------------- array(2) { [1]=> string(3) "one" [2]=> int(1) } array(2) { [0]=> string(4) "zero" [1]=> int(1) } Actual result: -------------- array(2) { [1]=> string(3) "one" [0]=> int(1) } array(1) { [0]=> string(4) "zero" } -- Edit bug report at https://bugs.php.net/bug.php?id=69017&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69017&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69017&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69017&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69017&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69017&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69017&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69017&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69017&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69017&r=support Expected behavior: https://bugs.php.net/fix.php?id=69017&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69017&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69017&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69017&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69017&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69017&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69017&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69017&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69017&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69017&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69017&r=mysqlcfg
