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"
)

有点复杂,但很容易扩展的技术:
假设你有一个数组
$a = [
'name' => 'ankit',
'age' => '33',
'dob' => '1984-04-12'
];
假设您有一个Person类,它可能有来自这个数组的或多或少的属性。例如
class Person
{
private $name;
private $dob;
private $age;
private $company;
private $city;
}
如果你还想把数组改成person对象。你可以使用ArrayIterator类。
$arrayIterator = new \ArrayIterator($a); // Pass your array in the argument.
现在你有了迭代器对象。
创建一个扩展FilterIterator class的类;你必须定义抽象方法accept。遵循示例
class PersonIterator extends \FilterIterator
{
public function accept()
{
return property_exists('Person', parent::current());
}
}
上面的实现只在类中存在该属性时才会绑定它。
在类PersonIterator中再添加一个方法
public function getObject(Person $object)
{
foreach ($this as $key => $value)
{
$object->{'set' . underscoreToCamelCase($key)}($value);
}
return $object;
}
确保在类中定义了mutator。 现在,您可以在想要创建对象的地方调用这些函数。
$arrayiterator = new \ArrayIterator($a);
$personIterator = new \PersonIterator($arrayiterator);
$personIterator->getObject(); // this will return your Person Object.
其他回答
据我所知,没有内置的方法可以做到这一点,但它就像一个简单的循环一样简单:
$obj= new stdClass();
foreach ($array as $k=> $v) {
$obj->{$k} = $v;
}
如果你需要递归地构建你的对象,你可以详细说明。
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);
可以使用(object)函数将数组转换为对象。
$arr= [128=> ['status'=>
'Figure A. Facebook \'s horizontal scrollbars showing up on a 1024x768 screen resolution.'],
129=>['status'=>'The other day at work, I had some spare time']];
$ArrToObject=(object)$arr;
var_dump($ArrToObject);
结果将是一个包含数组的对象:
对象(stdClass)#1048(2){[128]=>数组(1){ ["地位"]= > 字符串(87)“图a: Facebook的水平滚动条显示在1024x768分辨率的屏幕上。”} [129]=>数组(1){ ["地位"]= > 字符串(44)“前几天上班,我有一些空闲时间”}}
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"
}
}
]
}
}
}
如果你需要将一个数组强制转换为一个特定的类(在我的例子中,我需要对象类型为Google_Service_AndroidPublisher_Resource_Inappproducts),你可以像这样从stdClass中将类名str_replace为预期的类:
function castArrayToClass(array $array, string $className)
{
//first cast the array to stdClass
$subject = serialize((object)$array);
//then change the class name
$converted = str_replace(
'O:8:"stdClass"',
'O:'.strlen($className).':"'.$className.'"',
$subject
);
unset($subject);
return unserialize($converted);
}
