From: greevex at gmail dot com Operating system: Scientific Linux 6.5 PHP version: 5.5.11 Package: Scripting Engine problem Bug Type: Bug Bug description:Array copy and reference problem in pecl module. Description: ------------ php-pecl-mongo version 1.4.5 I don't really think that it's problem in mongo pecl module, because this is problem of an inside PHP Engine (optimizations for passing variables by reference before it's changed). Test script: --------------- function prepare() { return [ 'key' => 'test1', 'create' => time(), 'update' => 0, 'value' => 0 ]; } function save($array2) { $db = (new Mongo('localhost'))->selectDB('test'); $collection = $db->selectCollection('test'); // array2: new field _id would be added, insert requesting param by reference $collection->insert($array2); // some field only in array1, but _id field in both arrays return $array2; } $array1 = prepare(); $array2 = save($array1); // array1: add some field to array1 $array1['some'] = true; var_dump(isset($array1['_id']), isset($array2['_id']), isset($array1['some']), isset($array2['some'])); Expected result: ---------------- bool(false) bool(true) bool(true) bool(false) Actual result: -------------- bool(true) bool(true) bool(true) bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=67100&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=67100&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=67100&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=67100&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=67100&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=67100&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=67100&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=67100&r=needscript Try newer version: https://bugs.php.net/fix.php?id=67100&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=67100&r=support Expected behavior: https://bugs.php.net/fix.php?id=67100&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=67100&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=67100&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=67100&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=67100&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=67100&r=dst IIS Stability: https://bugs.php.net/fix.php?id=67100&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=67100&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=67100&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=67100&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=67100&r=mysqlcfg
