这是我的建议，如果你的对象中有私有成员的对象:

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;
}

这里发布的所有其他答案都只使用公共属性。下面是一个使用反射和getter处理类javabean对象的解决方案:

function entity2array($entity, $recursionDepth = 2) {
    $result = array();
    $class = new ReflectionClass(get_class($entity));
    foreach ($class->getMethods(ReflectionMethod::IS_PUBLIC) as $method) {
        $methodName = $method->name;
        if (strpos($methodName, "get") === 0 && strlen($methodName) > 3) {
            $propertyName = lcfirst(substr($methodName, 3));
            $value = $method->invoke($entity);

            if (is_object($value)) {
                if ($recursionDepth > 0) {
                    $result[$propertyName] = $this->entity2array($value, $recursionDepth - 1);
                }
                else {
                    $result[$propertyName] = "***";  // Stop recursion
                }
            }
            else {
                $result[$propertyName] = $value;
            }
        }
    }
    return $result;
}

对“众所周知的”代码的一些改进

/*** mixed Obj2Array(mixed Obj)***************************************/ 
static public function Obj2Array($_Obj) {
    if (is_object($_Obj))
        $_Obj = get_object_vars($_Obj);
    return(is_array($_Obj) ? array_map(__METHOD__, $_Obj) : $_Obj);   
} // BW_Conv::Obj2Array

注意，如果函数是类的成员(如上所述)，必须将__FUNCTION__更改为__METHOD__

要将对象转换为数组，只需显式强制转换:

$name_of_array = (array) $name_of_object;

我使用这个(需要递归解决适当的关键字):

    /**
     * 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;
    }

用法示例，代码如下:

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)

将打印这个:

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

这不是一个新的解决方案，但是在可用时包含了toArray方法转换

function objectToArray($r)
{
  if (is_object($r)) {
    if (method_exists($r, 'toArray')) {
      return $r->toArray(); // returns result directly
    } else {
      $r = get_object_vars($r);
    }
  }

  if (is_array($r)) {
    $r = array_map(__FUNCTION__, $r); // recursive function call
  }

  return $r;
}
