Code

此函数的工作原理与json_decode(json_encode($arr)， false)相同。

function arrayToObject(array $arr)
{
    $flat = array_keys($arr) === range(0, count($arr) - 1);
    $out = $flat ? [] : new \stdClass();

    foreach ($arr as $key => $value) {
        $temp = is_array($value) ? $this->arrayToObject($value) : $value;

        if ($flat) {
            $out[] = $temp;
        } else {
            $out->{$key} = $temp;
        }
    }

    return $out;
}

测试

测试1:平面阵列

$arr = ["a", "b", "c"];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));

输出:

array(
    0 => 'a',
    1 => 'b',
    2 => 'c',
)
array(
    0 => 'a',
    1 => 'b',
    2 => 'c',
)

测试2:对象数组

$arr = [["a" => 1], ["a" => 1], ["a" => 1]];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));

输出:

array(
    0 => stdClass::__set_state(array('a' => 1,)),
    1 => stdClass::__set_state(array('a' => 1,)),
    2 => stdClass::__set_state(array('a' => 1,)),
)
array(
    0 => stdClass::__set_state(array('a' => 1,)),
    1 => stdClass::__set_state(array('a' => 1,)),
    2 => stdClass::__set_state(array('a' => 1,)),
)

测试3:对象

$arr = ["a" => 1];
var_export(json_decode($arr));
var_export($this->arrayToObject($arr));

输出:

stdClass::__set_state(array('a' => 1,))
stdClass::__set_state(array('a' => 1,))

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;
}

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;

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;
}

世界上最好的方法:)

function arrayToObject($conArray)
{
    if(is_array($conArray)){
        /*
        * Return array converted to object
        * Using __FUNCTION__ (Magic constant)
        * for recursive call
        */
        return (object) array_map(__FUNCTION__, $conArray);
    }else{
        // Return object
        return $conArray;
    }
}

如果使用不同的方法，就会出现问题。这是最好的方法。你所见过的。

它的方法很简单，这将为递归数组创建一个对象:

$object = json_decode(json_encode((object) $yourArray), FALSE);
