这里有三种方法:

Fake a real object: class convert { public $varible; public function __construct($array) { $this = $array; } public static function toObject($array) { $array = new convert($array); return $array; } } Convert the array into an object by casting it to an object: $array = array( // ... ); $object = (object) $array; Manually convert the array into an object: $object = object; foreach ($arr as $key => $value) { $object->{$key} = $value; }

使用json_encode是有问题的，因为它处理非UTF-8数据的方式。值得注意的是，json_encode/json_encode方法也将非关联数组作为数组。这可能是你想要的，也可能不是。我最近需要重新创建这个解决方案的功能，但没有使用json_ functions。这是我想到的:

/**
 * Returns true if the array has only integer keys
 */
function isArrayAssociative(array $array) {
    return (bool)count(array_filter(array_keys($array), 'is_string'));
}

/**
 * Converts an array to an object, but leaves non-associative arrays as arrays. 
 * This is the same logic that `json_decode(json_encode($arr), false)` uses.
 */
function arrayToObject(array $array, $maxDepth = 10) {
    if($maxDepth == 0) {
        return $array;
    }

    if(isArrayAssociative($array)) {
        $newObject = new \stdClass;
        foreach ($array as $key => $value) {
            if(is_array($value)) {
                $newObject->{$key} = arrayToObject($value, $maxDepth - 1);
            } else {
                $newObject->{$key} = $value;
            }
        }
        return $newObject;
    } else {

        $newArray = array();
        foreach ($array as $value) {
            if(is_array($value)) {
                $newArray[] = arrayToObject($value, $maxDepth - 1);
            } else {
                $newArray[] = $value;
            }                
        }
        return $newArray;
    }
}

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,))

快速攻击:

// assuming $var is a multidimensional array
$obj = json_decode (json_encode ($var), FALSE);

不漂亮，但很好用。

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);

你可以使用反射:

<?php

$array = ['name'=>'maria','age'=>33];

class Person {

    public $name;
    public $age;

    public function __construct(string $name, string $age){
        $this->name  = $name;
        $this->age = $age;
    }
}

function arrayToObject(array $array, string $class_name){

    $r = new ReflectionClass($class_name);
    $object = $r->newInstanceWithoutConstructor();
    $list = $r->getProperties();
    foreach($list as $prop){
      $prop->setAccessible(true);
      if(isset($array[$prop->name]))
        $prop->setValue($object, $array[$prop->name]);
    } 

    return $object;

}

$pessoa1 = arrayToObject($array, 'Person');
var_dump($pessoa1);
