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"
    )

当前回答

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;
}

其他回答

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;
        }
        }
}

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);

使用我创建的这个函数:

function buildObject($class,$data){
    $object = new $class;
    foreach($data as $key=>$value){
        if(property_exists($class,$key)){
            $object->{'set'.ucfirst($key)}($value);
        }
    }
    return $object;
}

用法:

$myObject = buildObject('MyClassName',$myArray);

简单的方法是

$object = (object)$array;

但这不是你想要的。如果你想要对象,你想要实现一些东西,但这在这个问题中是缺失的。仅仅为了使用对象而使用对象是没有意义的。

function object_to_array($data)
{
    if (is_array($data) || is_object($data))
    {
        $result = array();
        foreach ($data as $key => $value)
        {
            $result[$key] = object_to_array($value);
        }
        return $result;
    }
    return $data;
}

function array_to_object($data)
{
    if (is_array($data) || is_object($data))
    {
        $result= new stdClass();
        foreach ($data as $key => $value)
        {
            $result->$key = array_to_object($value);
        }
        return $result;
    }
    return $data;
}
