如何将这样的数组转换为对象?

[128] => Array
    (
        [status] => "Figure A.
 Facebook's horizontal scrollbars showing up on a 1024x768 screen resolution."
    )

[129] => Array
    (
        [status] => "The other day at work, I had some spare time"
    )

如果你需要将一个数组强制转换为一个特定的类(在我的例子中,我需要对象类型为Google_Service_AndroidPublisher_Resource_Inappproducts),你可以像这样从stdClass中将类名str_replace为预期的类:

function castArrayToClass(array $array, string $className)
{
    //first cast the array to stdClass
    $subject = serialize((object)$array);
    //then change the class name
    $converted = str_replace(
        'O:8:"stdClass"',
        'O:'.strlen($className).':"'.$className.'"',
        $subject
    );
    unset($subject);

    return unserialize($converted);
}

使用json_encode是有问题的,因为它处理非UTF-8数据的方式。值得注意的是,json_encode/json_encode方法也将非关联数组作为数组。这可能是你想要的,也可能不是。我最近需要重新创建这个解决方案的功能,但没有使用json_ functions。这是我想到的:

/**
 * Returns true if the array has only integer keys
 */
function isArrayAssociative(array $array) {
    return (bool)count(array_filter(array_keys($array), 'is_string'));
}

/**
 * Converts an array to an object, but leaves non-associative arrays as arrays. 
 * This is the same logic that `json_decode(json_encode($arr), false)` uses.
 */
function arrayToObject(array $array, $maxDepth = 10) {
    if($maxDepth == 0) {
        return $array;
    }

    if(isArrayAssociative($array)) {
        $newObject = new \stdClass;
        foreach ($array as $key => $value) {
            if(is_array($value)) {
                $newObject->{$key} = arrayToObject($value, $maxDepth - 1);
            } else {
                $newObject->{$key} = $value;
            }
        }
        return $newObject;
    } else {

        $newArray = array();
        foreach ($array as $value) {
            if(is_array($value)) {
                $newArray[] = arrayToObject($value, $maxDepth - 1);
            } else {
                $newArray[] = $value;
            }                
        }
        return $newArray;
    }
}

可以使用(object)函数将数组转换为对象。

$arr= [128=> ['status'=>
                 'Figure A. Facebook \'s horizontal scrollbars showing up on a 1024x768 screen resolution.'],
                  129=>['status'=>'The other day at work, I had some spare time']];

            $ArrToObject=(object)$arr;
            var_dump($ArrToObject);

结果将是一个包含数组的对象:

对象(stdClass)#1048(2){[128]=>数组(1){ ["地位"]= > 字符串(87)“图a: Facebook的水平滚动条显示在1024x768分辨率的屏幕上。”} [129]=>数组(1){ ["地位"]= > 字符串(44)“前几天上班,我有一些空闲时间”}}

这里有三种方法:

Fake a real object: class convert { public $varible; public function __construct($array) { $this = $array; } public static function toObject($array) { $array = new convert($array); return $array; } } Convert the array into an object by casting it to an object: $array = array( // ... ); $object = (object) $array; Manually convert the array into an object: $object = object; foreach ($arr as $key => $value) { $object->{$key} = $value; }

递归是你的朋友:

function __toObject(Array $arr) {
    $obj = new stdClass();
    foreach($arr as $key=>$val) {
        if (is_array($val)) {
            $val = __toObject($val);
        }
        $obj->$key = $val;
    }

    return $obj;
}

显然,这只是对其他人答案的推断,但这里有一个递归函数,可以将任何多维数组转换为对象:

   function convert_array_to_object($array){
      $obj= new stdClass();
      foreach ($array as $k=> $v) {
         if (is_array($v)){
            $v = convert_array_to_object($v);   
         }
         $obj->{strtolower($k)} = $v;
      }
      return $obj;
   }

记住,如果数组有数字键,它们仍然可以通过{}在结果对象中引用(例如:$obj->prop->{4}->prop)
