It look like reading a file with file_get_contents using a streamwrapper class destroys some part of the zend engine. After reading the file all sorts of odd problems occur. I tracked it down to undefined variables returned by stream_stat() in my stream wrapper class. Casting the values to an integer fixes it. Test script: --------------- class StreamWrapper { public function stream_stat() { return array( 'atime' => $this->notset, 'mtime' => $this->notset, 'ctime' => $this->notset, ); } } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53903&edit=1
