How to convert an stdClass to an array?

I have a problem to convert an object stdClass to array.

I have tried in this way:

return (array) $booking;

or

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

or

return (array) json_decode($booking);

The array before the cast is full with one record, after my try to cast it is empty. How to cast / convert it without delete its rows?

array before cast:

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

after cast is empty NULL if I try to make a var_dump($booking);

I have also tried this function but always empty:

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;
        }
    }

Here's how I use it in Laravel without Eloquent.

function getUsers(){ 

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

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

Here is the best Object to Array function I have - works recursively:

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);

Use the built in type cast functionality, simply type

$realArray = (array)$stdClass;

The following code will read all emails & print the Subject, Body & Date.

<?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);
?>

This outputs the following:

$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

Having struggled with various suggestions I have used trial & error to come up with this solution. Hope it helps.

The lazy one-liner method

You can do this in a one liner using the JSON methods if you're willing to lose a tiny bit of performance (though some have reported it being faster than iterating through the objects recursively - most likely because PHP is slow at calling functions). "But I already did this" you say. Not exactly - you used json_decode on the array, but you need to encode it with json_encode first.

Requirements

The json_encode and json_decode methods. These are automatically bundled in PHP 5.2.0 and up. If you use any older version there's also a PECL library (that said, in that case you should really update your PHP installation. Support for 5.1 stopped in 2006.)

Converting an array/stdClass -> stdClass

$stdClass = json_decode(json_encode($booking));

Converting an array/stdClass -> array

The manual specifies the second argument of json_decode as:

assoc
When TRUE, returned objects will be converted into associative arrays.

Hence the following line will convert your entire object into an array:

$array = json_decode(json_encode($booking), true);

Here is a version of Carlo's answer that can be used in a class:

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;
    }
}

This function worked for me: 

function cvf_convert_object_to_array($data) {

    if (is_object($data)) {
        $data = get_object_vars($data);
    }

    if (is_array($data)) {
        return array_map(__FUNCTION__, $data);
    }
    else {
        return $data;
    }
}

Just googled it, and found here a handy function that is useful for converting stdClass object to array recursively.

<?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;
 }
}
?>

EDIT: I updated this answer with content from linked source (which is also changed now), thanks to mason81 for suggesting me.

Since it's an array before you cast it, casting it makes no sense.

You may want a recursive cast, which would look something like this:

function arrayCastRecursive($array)
{
    if (is_array($array)) {
        foreach ($array as $key => $value) {
            if (is_array($value)) {
                $array[$key] = arrayCastRecursive($value);
            }
            if ($value instanceof stdClass) {
                $array[$key] = arrayCastRecursive((array)$value);
            }
        }
    }
    if ($array instanceof stdClass) {
        return arrayCastRecursive((array)$array);
    }
    return $array;
}

Usage:

$obj = new stdClass;
$obj->aaa = 'asdf';
$obj->bbb = 'adsf43';
$arr = array('asdf', array($obj, 3));

var_dump($arr);
$arr = arrayCastRecursive($arr);
var_dump($arr);

Result before:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        object(stdClass)[1]
          public 'aaa' => string 'asdf' (length = 4)
          public 'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Result after:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        array
          'aaa' => string 'asdf' (length = 4)
          'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Note:

Tested and working with complex arrays where a stdClass object can contain other stdClass objects.

use this function to get a standard array back of the type you are after... 

return get_object_vars($booking);
