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);
}

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"
          }
        }
      ]
    }
  }
}

我使用的一个(它是类成员):

const MAX_LEVEL = 5; // change it as needed

public function arrayToObject($a, $level=0)
{

    if(!is_array($a)) {
        throw new InvalidArgumentException(sprintf('Type %s cannot be cast, array expected', gettype($a)));
    }

    if($level > self::MAX_LEVEL) {
        throw new OverflowException(sprintf('%s stack overflow: %d exceeds max recursion level', __METHOD__, $level));
    }

    $o = new stdClass();
    foreach($a as $key => $value) {
        if(is_array($value)) { // convert value recursively
            $value = $this->arrayToObject($value, $level+1);
        }
        $o->{$key} = $value;
    }
    return $o;
}

我肯定会用这样一种干净的方式:

<?php

class Person {

  private $name;
  private $age;
  private $sexe;

  function __construct ($payload)
  {
     if (is_array($payload))
          $this->from_array($payload);
  }


  public function from_array($array)
  {
     foreach(get_object_vars($this) as $attrName => $attrValue)
        $this->{$attrName} = $array[$attrName];
  }

  public function say_hi ()
  {
     print "hi my name is {$this->name}";
  }
}

print_r($_POST);
$mike = new Person($_POST);
$mike->say_hi();

?>

如果你提交:

你会得到这个:

我发现这更符合逻辑的比较以上的答案从对象应该用于他们的目的(封装可爱的小对象)。

此外，使用get_object_vars确保在被操纵的对象中没有创建额外的属性(您不希望汽车有姓，也不希望人有4个轮子)。

受到所有这些代码的启发，我尝试创建一个增强版本，支持:特定的类名，避免构造函数方法，'beans'模式和严格模式(仅设置现有属性):

    class Util {

static function arrayToObject($array, $class = 'stdClass', $strict = false) {
        if (!is_array($array)) {
            return $array;
        }

        //create an instance of an class without calling class's constructor
        $object = unserialize(
                sprintf(
                        'O:%d:"%s":0:{}', strlen($class), $class
                )
        );

        if (is_array($array) && count($array) > 0) {
            foreach ($array as $name => $value) {
                $name = strtolower(trim($name));
                if (!empty($name)) {

                    if(method_exists($object, 'set'.$name)){
                        $object->{'set'.$name}(Util::arrayToObject($value));
                    }else{
                        if(($strict)){

                            if(property_exists($class, $name)){

                                $object->$name = Util::arrayToObject($value); 

                            }

                        }else{
                            $object->$name = Util::arrayToObject($value); 
                        }

                    }

                }
            }
            return $object;
        } else {
            return FALSE;
        }
        }
}

实际上，如果你想在多维数组中使用这个你就需要使用一些递归。

static public function array_to_object(array $array)
{
    foreach($array as $key => $value)
    {
        if(is_array($value))
        {
            $array[$key] = self::array_to_object($value);
        }
    }
    return (object)$array;
}
