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"
    )

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;
}

其他回答

有点复杂,但很容易扩展的技术:

假设你有一个数组

$a = [
     'name' => 'ankit',
     'age' => '33',
     'dob' => '1984-04-12'
];

假设您有一个Person类,它可能有来自这个数组的或多或少的属性。例如

class Person 
{
    private $name;
    private $dob;
    private $age;
    private $company;
    private $city;
}

如果你还想把数组改成person对象。你可以使用ArrayIterator类。

$arrayIterator = new \ArrayIterator($a); // Pass your array in the argument.

现在你有了迭代器对象。

创建一个扩展FilterIterator class的类;你必须定义抽象方法accept。遵循示例

class PersonIterator extends \FilterIterator
{
    public function accept()
    {
        return property_exists('Person', parent::current());
    }
}

上面的实现只在类中存在该属性时才会绑定它。

在类PersonIterator中再添加一个方法

public function getObject(Person $object)
{
        foreach ($this as $key => $value)
        {
            $object->{'set' . underscoreToCamelCase($key)}($value);
        }
        return $object;
}

确保在类中定义了mutator。 现在,您可以在想要创建对象的地方调用这些函数。

$arrayiterator = new \ArrayIterator($a);
$personIterator = new \PersonIterator($arrayiterator);

$personIterator->getObject(); // this will return your Person Object. 

我使用以下代码将Yaml文件关联数组解析为对象状态。

这将检查所有提供的数组中是否隐藏有对象,并将它们转换为对象。

    /**
     * Makes a config object from an array, making the first level keys properties a new object.
     * Property values are converted to camelCase and are not set if one already exists.
     * @param array $configArray Config array.
     * @param boolean $strict To return an empty object if $configArray is not an array
     * @return stdObject The config object
     */
    public function makeConfigFromArray($configArray = [],$strict = true)
    {
        $object = new stdClass();

        if (!is_array($configArray)) {
            if(!$strict && !is_null($configArray)) {
                return $configArray;
            }
            return $object;
        }

        foreach ($configArray as $name => $value) {
            $_name = camel_case($name);
            if(is_array($value)) {
                $makeobject = true;
                foreach($value as $key => $val) {
                    if(is_numeric(substr($key,0,1))) {
                        $makeobject = false;
                    }
                    if(is_array($val)) {
                        $value[$key] = $this->makeConfigFromArray($val,false);
                    }
                }
                if($makeobject) {
                    $object->{$name} = $object->{$_name} = $this->makeConfigFromArray($value,false);
                }
                else {
                    $object->{$name} = $object->{$_name} = $value;
                }

            }
            else {
                $object->{$name} = $object->{$_name} = $value;
            }
        }

        return $object;
    }

这将把yaml配置为

fields:
    abc:
        type: formfield
        something:
            - a
            - b
            - c
            - d:
                foo: 
                   bar

到由以下数组组成的数组:

array:1 [
  "fields" => array:1 [
    "abc" => array:2 [
      "type" => "formfield"
      "something" => array:4 [
        0 => "a"
        1 => "b"
        2 => "c"
        3 => array:1 [
          "d" => array:1 [
            "foo" => "bar"
          ]
        ]
      ]
    ]
  ]
]

以…为目标:

{#325
  +"fields": {#326
    +"abc": {#324
      +"type": "formfield"
      +"something": array:4 [
        0 => "a"
        1 => "b"
        2 => "c"
        3 => {#328
          +"d": {#327
            +"foo": "bar"
          }
        }
      ]
    }
  }
}

多维数组转换为对象。此代码用于转换必应搜索API的尝试和捕获方法。

try {
        // Perform the Web request and get the JSON response
        $context = stream_context_create($options);
        $results = file_get_contents($url . "?cc=" . $country . "&category=" . $type, false, $context);
        $results = json_decode($results);
        return response()->json($results);
    } catch (\Exception $e) {
        $results = array('value' => array(
                (object) array(
                    "name" => "Unable to Retrive News",
                    "url" => "http://www.sample.com/",
                    "image" => (object) array("thumbnail" => (object) array("contentUrl" => "")),
                    "publishedAt" => "",
                    "description" => "")
            )
        );
        $results = (object) $results;
        return response()->json($results);
    }

这需要PHP7,因为我选择使用lambda函数来锁定主函数中的'innerfunc'。lambda函数是递归调用的,因此需要:"use (&$innerfunc)"。你可以在PHP5中这样做,但不能隐藏innerfunc。

function convertArray2Object($defs) {
    $innerfunc = function ($a) use ( &$innerfunc ) {
       return (is_array($a)) ? (object) array_map($innerfunc, $a) : $a; 
    };
    return (object) array_map($innerfunc, $defs);
}

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;
}
