Link: http://git.php.net/?p=php-src.git;a=commitdiff;h=aa0adce47d9b8ead59efede63a769e395e27bcd5 Log: Fix bug #64023 (__toString() & SplFileInfo) Defining a __toString() method was having no effect when concatenating the object. This was because the cast_object() handler would ignore __toString(). Using echo() directly would actually use __toString(), but this was a bug: the ECHO handler would try zend_std_cast_object_tostring() before cast_object(), but cast_object() should have priority as zend_std_cast_object_tostring() assumes an object with a zend_class_entry.
