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"
)

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;
}

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.
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"
}
}
]
}
}
}
多维数组转换为对象。此代码用于转换必应搜索API的尝试和捕获方法。
try {
// Perform the Web request and get the JSON response
$context = stream_context_create($options);
$results = file_get_contents($url . "?cc=" . $country . "&category=" . $type, false, $context);
$results = json_decode($results);
return response()->json($results);
} catch (\Exception $e) {
$results = array('value' => array(
(object) array(
"name" => "Unable to Retrive News",
"url" => "http://www.sample.com/",
"image" => (object) array("thumbnail" => (object) array("contentUrl" => "")),
"publishedAt" => "",
"description" => "")
)
);
$results = (object) $results;
return response()->json($results);
}
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);
}
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;
}
