From: anna at foolab dot ca Operating system: Debian 3.2.65 PHP version: master-Git-2015-05-22 (Git) Package: *General Issues Bug Type: Bug Bug description:BC: cannot use array element directly when calling a method Description: ------------ I found this issue when testing a Magento 1.9 application. Using array elements to call a method on an object doesn't work in php7, but used to work in php5. I made a simplified example in the test script below. Test script: --------------- <?php class Item { public function save() { echo 'saved'; } } $callback = [new Item(), 'save']; // This works on both php5 and php7 $method = $callback[1]; $callback[0]->$method(); // This works on php5 only $callback[0]->$callback[1](); Expected result: ---------------- Expected "savedsaved" output. Actual result: -------------- saved Notice: Array to string conversion in /var/www/test/array_function.php on line 15 Notice: Undefined property: Item::$Array in /var/www/test/array_function.php on line 15 Fatal error: Function name must be a string in /var/www/test/array_function.php on line 15 -- Edit bug report at https://bugs.php.net/bug.php?id=69694&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69694&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69694&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69694&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69694&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69694&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69694&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69694&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69694&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69694&r=support Expected behavior: https://bugs.php.net/fix.php?id=69694&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69694&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69694&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69694&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69694&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69694&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69694&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69694&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69694&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69694&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69694&r=mysqlcfg
