Convert a PHP object to an associative array

Question

I\'m integrating an API to my website which works with data stored in objects while my code is written using arrays.

I\'d like a quick-and-dirty function to convert

Answer 1

By using typecasting you can resolve your problem. Just add the following lines to your return object:

$arrObj = array(yourReturnedObject);

You can also add a new key and value pair to it by using:

$arrObj['key'] = value;

Answer 2

I use this (needed recursive solution with proper keys):

    /**
     * This method returns the array corresponding to an object, including non public members.
     *
     * If the deep flag is true, is will operate recursively, otherwise (if false) just at the first level.
     *
     * @param object $obj
     * @param bool $deep = true
     * @return array
     * @throws \Exception
     */
    public static function objectToArray(object $obj, bool $deep = true)
    {
        $reflectionClass = new \ReflectionClass(get_class($obj));
        $array = [];
        foreach ($reflectionClass->getProperties() as $property) {
            $property->setAccessible(true);
            $val = $property->getValue($obj);
            if (true === $deep && is_object($val)) {
                $val = self::objectToArray($val);
            }
            $array[$property->getName()] = $val;
            $property->setAccessible(false);
        }
        return $array;
    }

Example of usage, the following code:

class AA{
    public $bb = null;
    protected $one = 11;

}

class BB{
    protected $two = 22;
}


$a = new AA();
$b = new BB();
$a->bb = $b;

var_dump($a)

Will print this:

array(2) {
  ["bb"] => array(1) {
    ["two"] => int(22)
  }
  ["one"] => int(11)
}

Answer 3

You can quickly convert deeply nested objects to associative arrays by relying on the behavior of the JSON encode/decode functions:

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

Answer 4

You might want to do this when you obtain data as objects from databases:

// Suppose 'result' is the end product from some query $query

$result = $mysqli->query($query);
$result = db_result_to_array($result);

function db_result_to_array($result)
{
    $res_array = array();

    for ($count=0; $row = $result->fetch_assoc(); $count++)
        $res_array[$count] = $row;

    return $res_array;
}

Answer 5

There's my proposal, if you have objects in objects with even private members:

public function dismount($object) {
    $reflectionClass = new \ReflectionClass(get_class($object));
    $array = array();
    foreach ($reflectionClass->getProperties() as $property) {
        $property->setAccessible(true);
        if (is_object($property->getValue($object))) {
            $array[$property->getName()] = $this->dismount($property->getValue($object));
        } else {
            $array[$property->getName()] = $property->getValue($object);
        }
        $property->setAccessible(false);
    }
    return $array;
}

Answer 6

Type cast your object to an array.

$arr =  (array) $Obj;

It will solve your problem.
