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

一个衬套

$object= json_decode(json_encode($result_array, JSON_FORCE_OBJECT));

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;
}

根据你需要的位置和访问对象的方式有不同的方法。

例如:只需对它进行类型转换

$object =  (object) $yourArray;

然而,最兼容的方法是使用一个实用程序方法(还不是PHP的一部分),它实现了基于指定类型的字符串的标准PHP强制转换(或者忽略它,只是去引用值):

/**
 * dereference a value and optionally setting its type
 *
 * @param mixed $mixed
 * @param null  $type (optional)
 *
 * @return mixed $mixed set as $type
 */
function rettype($mixed, $type = NULL) {
    $type === NULL || settype($mixed, $type);
    return $mixed;
}

您案例中的使用示例(在线演示):

$yourArray = Array('status' => 'Figure A. ...');

echo rettype($yourArray, 'object')->status; // prints "Figure A. ..."

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();

?>

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)。

您可以简单地使用类型强制转换将数组转换为对象。

// *convert array to object* Array([id]=> 321313[username]=>shahbaz)
$object = (object) $array_name;

//now it is converted to object and you can access it.
echo $object->username;
