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"
)

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 $o;
}
其他回答
使用我创建的这个函数:
function buildObject($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);
我使用以下代码将Yaml文件关联数组解析为对象状态。
这将检查所有提供的数组中是否隐藏有对象,并将它们转换为对象。
/**
* Makes a config object from an array, making the first level keys properties a new object.
* Property values are converted to camelCase and are not set if one already exists.
* @param array $configArray Config array.
* @param boolean $strict To return an empty object if $configArray is not an array
* @return stdObject The config object
*/
public function makeConfigFromArray($configArray = [],$strict = true)
{
$object = new stdClass();
if (!is_array($configArray)) {
if(!$strict && !is_null($configArray)) {
return $configArray;
}
return $object;
}
foreach ($configArray as $name => $value) {
$_name = camel_case($name);
if(is_array($value)) {
$makeobject = true;
foreach($value as $key => $val) {
if(is_numeric(substr($key,0,1))) {
$makeobject = false;
}
if(is_array($val)) {
$value[$key] = $this->makeConfigFromArray($val,false);
}
}
if($makeobject) {
$object->{$name} = $object->{$_name} = $this->makeConfigFromArray($value,false);
}
else {
$object->{$name} = $object->{$_name} = $value;
}
}
else {
$object->{$name} = $object->{$_name} = $value;
}
}
return $object;
}
这将把yaml配置为
fields:
abc:
type: formfield
something:
- a
- b
- c
- d:
foo:
bar
到由以下数组组成的数组:
array:1 [
"fields" => array:1 [
"abc" => array:2 [
"type" => "formfield"
"something" => array:4 [
0 => "a"
1 => "b"
2 => "c"
3 => array:1 [
"d" => array:1 [
"foo" => "bar"
]
]
]
]
]
]
以…为目标:
{#325
+"fields": {#326
+"abc": {#324
+"type": "formfield"
+"something": array:4 [
0 => "a"
1 => "b"
2 => "c"
3 => {#328
+"d": {#327
+"foo": "bar"
}
}
]
}
}
}
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;
}
}
实际上,如果你想在多维数组中使用这个你就需要使用一些递归。
static public function array_to_object(array $array)
{
foreach($array as $key => $value)
{
if(is_array($value))
{
$array[$key] = self::array_to_object($value);
}
}
return (object)$array;
}
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;
}
