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"
    )

你也可以通过在变量的左边添加(object)来创建一个新对象。

<?php
$a = Array
    ( 'status' => " text" );
var_dump($a);
$b = (object)$a;
var_dump($b);
var_dump($b->status);

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;
}

这个方法对我很管用

  function array_to_obj($array, &$obj)
  {
    foreach ($array as $key => $value)
    {
      if (is_array($value))
      {
      $obj->$key = new stdClass();
      array_to_obj($value, $obj->$key);
      }
      else
      {
        $obj->$key = $value;
      }
    }
  return $obj;
  }

function arrayToObject($array)
{
 $object= new stdClass();
 return array_to_obj($array,$object);
}

用法:

$myobject = arrayToObject($array);
print_r($myobject);

返回:

    [127] => stdClass Object
        (
            [status] => Have you ever created a really great looking website design
        )

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

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

像往常一样,你可以这样循环:

foreach($myobject as $obj)
{
  echo $obj->status;
}

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. 

你也可以使用ArrayObject,例如:

<?php
    $arr = array("test",
                 array("one"=>1,"two"=>2,"three"=>3), 
                 array("one"=>1,"two"=>2,"three"=>3)
           );
    $o = new ArrayObject($arr);
    echo $o->offsetGet(2)["two"],"\n";
    foreach ($o as $key=>$val){
        if (is_array($val)) {
            foreach($val as $k => $v) {
               echo $k . ' => ' . $v,"\n";
            }
        }
        else
        {
               echo $val,"\n";
        }
    }
?>

//Output:
  2
  test
  one => 1
  two => 2
  three => 3
  one => 1
  two => 2
  three => 3

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)。
