通过使用(array)和(object)作为前缀，可以简单地将对象数组转换为标准数组，反之亦然

<?php
//defining an array
$a = array('a'=>'1','b'=>'2','c'=>'3','d'=>'4');

//defining an object array
$obj = new stdClass();
$obj->a = '1';
$obj->b = '2';
$obj->c = '3';
$obj->d = '4';

print_r($a);echo '<br>';
print_r($obj);echo '<br>';

//converting object array to array
$b = (array) $obj;
print_r($b);echo '<br>';

//converting array to object
$c = (object) $a;
print_r($c);echo '<br>';
?>

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

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; }

这需要PHP7，因为我选择使用lambda函数来锁定主函数中的'innerfunc'。lambda函数是递归调用的，因此需要:"use (&$innerfunc)"。你可以在PHP5中这样做，但不能隐藏innerfunc。

function convertArray2Object($defs) {
    $innerfunc = function ($a) use ( &$innerfunc ) {
       return (is_array($a)) ? (object) array_map($innerfunc, $a) : $a; 
    };
    return (object) array_map($innerfunc, $defs);
}

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;
    }
}

快速攻击:

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

不漂亮，但很好用。
