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__

这个答案只是这篇文章的不同答案的联合，但它是将具有简单值或数组的公有或私有属性的PHP对象转换为关联数组的解决方案…

function object_to_array($obj)
{
    if (is_object($obj))
        $obj = (array)$this->dismount($obj);
    if (is_array($obj)) {
        $new = array();
        foreach ($obj as $key => $val) {
            $new[$key] = $this->object_to_array($val);
        }
    }
    else
        $new = $obj;
    return $new;
}

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

$Menu = new Admin_Model_DbTable_Menu(); 
$row = $Menu->fetchRow($Menu->select()->where('id = ?', $id));
$Addmenu = new Admin_Form_Addmenu(); 
$Addmenu->populate($row->toArray());

@SpYk3HH的简短解决方案

function objectToArray($o)
{
    $a = array();
    foreach ($o as $k => $v)
        $a[$k] = (is_array($v) || is_object($v)) ? objectToArray($v): $v;

    return $a;
}

下面是一些代码:

function object_to_array($data) {
    if ((! is_array($data)) and (! is_object($data)))
        return 'xxx'; // $data;

    $result = array();

    $data = (array) $data;
    foreach ($data as $key => $value) {
        if (is_object($value))
            $value = (array) $value;
        if (is_array($value))
            $result[$key] = object_to_array($value);
        else
            $result[$key] = $value;
    }
    return $result;
}

通过依赖JSON编码/解码函数的行为，可以快速将深度嵌套的对象转换为关联数组:

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