$userapt = $user->getapartments()->getiterator();  while ($userapt->valid()) {   echo  ($userapt->key() . ' => ' . $userapt->current()) . "\n";      $userapt->next(); }  $useraptname = $user->getapartment()->getiterator();  while ($useraptname->valid()) {     ($useraptname->key() . ' => ' . var_dump($useraptname->current()) .

running this, following error:

catchable fatal error: object of class mybundle\entity\userapartment not converted string 500 internal server error - contexterrorexception

how can error fixed?
in advance!

you trying echo object

echo ($userapt->key() . ' => ' . $userapt->current()) . "\n";

you can solve implementing public function __tostring() {} method in userapartament class. in way when try echo $user->current() use __tostring() method show string value of object.

i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
