Bug #70778 [NEW]: Type hinting for objects

From: flavius Operating system: ArchLinux PHP version: 7.0.0RC5 Package: Scripting Engine problem Bug Type: Bug Bug description:Type hinting for objects Description: ------------ There is no way of making sure that a parameter is an object. Since there is a type hint for many is_*() functions, there should be one for objects too - maybe just \stdClass? Test script: --------------- <?php function acceptsObject(\stdClass $o) {} $anonymousObject = new class() {}; acceptsObject(new DOMDocument()); acceptsObject($anonymousObject); Actual result: -------------- PHP Fatal error: Uncaught TypeError: Argument 1 passed to acceptsObject() must be an instance of stdClass, instance of DOMDocument given, called in /tmp/test.php on line 5 and defined in /tmp/test.php:2 Stack trace: #0 /tmp/test.php(5): acceptsObject(Object(DOMDocument)) #1 {main} thrown in /tmp/test.php on line 2 Fatal error: Uncaught TypeError: Argument 1 passed to acceptsObject() must be an instance of stdClass, instance of DOMDocument given, called in /tmp/test.php on line 5 and defined in /tmp/test.php:2 Stack trace: #0 /tmp/test.php(5): acceptsObject(Object(DOMDocument)) #1 {main} thrown in /tmp/test.php on line 2 -- Edit bug report at https://bugs.php.net/bug.php?id=70778&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70778&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70778&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70778&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70778&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70778&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70778&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70778&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70778&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70778&r=support Expected behavior: https://bugs.php.net/fix.php?id=70778&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70778&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70778&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70778&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70778&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70778&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70778&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70778&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70778&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70778&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70778&r=mysqlcfg
