Req #79911 [NEW]: isset - error when using array acess on stdClass

From: gregorio at bonfante dot dev Operating system: PHP version: Irrelevant Package: Scripting Engine problem Bug Type: Feature/Change Request Bug description:isset - error when using array acess on stdClass Description: ------------ Similar to https://bugs.php.net/bug.php?id=55223 Not a bug, but still not what I expected. Using array access results in an error if the subject is an object without ArrayAccess. Not sure about the solution as I don't have familiarity with the PHP internals. I was able to adjust this behavior adding """ else if(!check_empty) { return 0; } """ to 'zend_std_has_dimension' on Zend/zend_object_handlers.c before the "else { zend_bad_array_access(ce); return 0; }" Test script: --------------- <?php $a = []; $o = new stdClass(); var_dump(isset($a->prop)); var_dump(isset($o[0])); Expected result: ---------------- bool(false) bool(false) Actual result: -------------- bool(false) Fatal error: Uncaught Error: Cannot use object of type stdClass as array in %s:%d Stack trace: #0 {main} thrown in %s on line %d -- Edit bug report at https://bugs.php.net/bug.php?id=79911&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79911&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79911&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79911&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79911&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79911&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79911&r=support Expected behavior: https://bugs.php.net/fix.php?id=79911&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79911&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79911&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79911&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79911&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79911&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79911&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79911&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79911&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79911&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79911&r=mysqlcfg
