怎么处理stdClass::__set_state

function object2array_pre(&$object) {
if (is_object($object)) {
$arr = (array)($object);
} else {
$arr = &$object;
}
if (is_array($arr)) {
foreach($arr as $varName => $varValue){
$arr[$varName] = $this->object2array($varValue);
}
}
return $arr;
}
function object2array(&$object) {
$object =  json_decode( json_encode( $object),true);
return  $object;
}
