Bug #70925 [NEW]: json_decode-d object become inacccessible after converting to array

From: speller at yandex dot ru Operating system: PHP version: 5.6.15 Package: Scripting Engine problem Bug Type: Bug Bug description:json_decode-d object become inacccessible after converting to array Description: ------------ Bug converting json_decoded-d object to array. First seen in PHP 5.4. Confirmed in PHP 5.6.15. See the test script. We have a simple array $a. Next we convert it to JSON and back. But after transcoding we can not access the array's values and get NULL or "Notice: Undefined offset: 1". If replace the line "$a = (array)json_decode(json_encode($a));" with "$a = (array)((object)$a);" everything is OK, converted array's values are accessible. The test script output is: array(2) { [1] => string(7) "value 1" [2] => string(7) "value 2" } string(7) "value 1" string(7) "value 1" array(2) { '1' => string(7) "value 1" '2' => string(7) "value 2" } NULL NULL Test script: --------------- <? error_reporting(0); $a = ['1' => 'value 1', '2' => 'value 2']; var_dump($a); var_dump($a[1]); var_dump($a['1']); $a = (array)json_decode(json_encode($a)); var_dump($a); var_dump($a[1]); var_dump($a['1']); ?> Expected result: ---------------- The values of the converted array must be accessible Actual result: -------------- NULL or Notice: Undefined offset: 1 -- Edit bug report at https://bugs.php.net/bug.php?id=70925&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70925&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70925&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70925&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70925&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70925&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70925&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70925&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70925&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70925&r=support Expected behavior: https://bugs.php.net/fix.php?id=70925&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70925&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70925&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70925&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70925&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70925&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70925&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70925&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70925&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70925&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70925&r=mysqlcfg
