php stdClass数组

我有一个问题转换对象stdClass到数组。我是这样尝试的:

return (array) $booking;

return (array) json_decode($booking,true);

return (array) json_decode($booking);

在强制转换之前的数组充满了一条记录，在我尝试强制转换后它是空的。如何强制转换/不删除它的行?

转换前的数组:

array(1) {   [0]=>   object(stdClass)#23 (36) {     ["id"]=>     string(1) "2"     ["name"]=>     string(0) ""     ["code"]=>     string(5) "56/13"   } }

后cast是空NULL如果我尝试做一个var_dump($booking);

我也尝试过这个功能，但总是空的:

public function objectToArray($d) {
        if (is_object($d)) {
            // Gets the properties of the given object
            // with get_object_vars function
            $d = get_object_vars($d);
        }

        if (is_array($d)) {
            /*
            * Return array converted to object
            * Using __FUNCTION__ (Magic constant)
            * for recursive call
            */
            return array_map(__FUNCTION__, $d);
        }
        else {
            // Return array
            return $d;
        }
    }

下面的代码将读取所有电子邮件并打印主题，正文和日期。

<?php
  $imap=imap_open("Mailbox","Email Address","Password");
  if($imap){$fixMessages=1+imap_num_msg($imap);  //Check no.of.msgs
/*
By adding 1 to "imap_num_msg($imap)" & starting at $count=1
   the "Start" & "End" non-messages are ignored
*/
    for ($count=1; $count<$fixMessages; $count++){
      $objectOverview=imap_fetch_overview($imap,$count,0);
print '<br>$objectOverview: '; print_r($objectOverview);
print '<br>objectSubject ='.($objectOverview[0]->subject));
print '<br>objectDate ='.($objectOverview[0]->date);
      $bodyMessage=imap_fetchbody($imap,$count,1);
print '<br>bodyMessage ='.$bodyMessage.'<br><br>';
    }  //for ($count=1; $count<$fixMessages; $count++)
  }  //if($imap)
  imap_close($imap);
?>

输出如下:

$objectOverview: Array ( [0] => stdClass Object ( [subject] => Hello
[from] => Email Address [to] => Email Address [date] => Sun, 16 Jul 2017 20:23:18 +0100
[message_id] =>  [size] => 741 [uid] => 2 [msgno] => 2 [recent] => 0 [flagged] => 0 
[answered] => 0 [deleted] => 0 [seen] => 1 [draft] => 0 [udate] => 1500232998 ) )
objectSubject =Hello
objectDate =Sun, 16 Jul 2017 20:23:18 +0100
bodyMessage =Test

在与各种建议作斗争后，我使用反复试验的方法提出了这个解决方案。希望能有所帮助。

其他回答

以下是Carlo的回答，可以在课堂上使用:

class Formatter
{
    public function objectToArray($data)
    {
        if (is_object($data)) {
            $data = get_object_vars($data);
        }

        if (is_array($data)) {
            return array_map(array($this, 'objectToArray'), $data);
        }

        return $data;
    }
}

以下是我如何在Laravel中使用它而没有Eloquent。

function getUsers(){ 

   $users = DB::select('select * from users');       
   $data = json_decode(json_encode($users), true); // to array 

   return view('page')->with('data', $data);
}

这是我拥有的最好的对象到数组的函数-递归地工作:

function object_to_array($obj, &$arr){
    
    if(!is_object($obj) && !is_array($obj)){
        $arr = $obj;
        return $arr;
    }
    
    foreach ($obj as $key => $value) {
        if (!empty($value)) {
            $arr[$key] = array();
            object_to_array_v2($value, $arr[$key]);
        } else {
            $arr[$key] = $value;
        }
    }

    return $arr;
}

$clean_array = object_to_array($object_data_here);

刚刚谷歌了一下，在这里发现了一个方便的函数，用于递归地将stdClass对象转换为数组。

<?php
function object_to_array($object) {
 if (is_object($object)) {
  return array_map(__FUNCTION__, get_object_vars($object));
 } else if (is_array($object)) {
  return array_map(__FUNCTION__, $object);
 } else {
  return $object;
 }
}
?>
