Bug #66482

Updated by Christian Kuhn about 6 years ago

 The extbase persistence layer (actually the object container) creates empty objects, by-passing the constructor, by unserializing a faked serialized empty object. 
 This no longer works in PHP 5.6. The @unserialize()@ call fails fatally ("Erroneous data format"). 

 Version      Description 
 5.6.0        *Manipulating the serialised data by replacing C: with O: to force object instantiation without calling the constructor will now fail.* 

 Instead of @unserialize()@, @public object ReflectionClass::newInstanceWithoutConstructor ( void )@ must be used: http://php.net/manual/de/reflectionclass.newinstancewithoutconstructor.php (PHP >= 5.4) 

 TYPO3 6.2 was declared to be compatible with PHP <= 5.5, until 2 days ago, when I reported https://forge.typo3.org/issues/66468.  
 Now, TYPO3 6.2 is officially declared as compatible to PHP 5.3.7-5.6.x (http://typo3.org/download/). Therefore I regard this a high priority issue, as extbase is factually broken on PHP 5.6. 

 The error occurs in this line: https://github.com/TYPO3/TYPO3.CMS/blob/TYPO3_6-2/typo3/sysext/extbase/Classes/Object/Container/Container.php#L121 

 PHP 5.3 will still need the unserialize() call. PHP 5.4-5.6 can use @ReflectionClass::newInstanceWithoutConstructor()@.
