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"
)

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($pessoa1);
其他回答
显然,这只是对其他人答案的推断,但这里有一个递归函数,可以将任何多维数组转换为对象:
function convert_array_to_object($array){
$obj= new stdClass();
foreach ($array as $k=> $v) {
if (is_array($v)){
$v = convert_array_to_object($v);
}
$obj->{strtolower($k)} = $v;
}
return $obj;
}
记住,如果数组有数字键,它们仍然可以通过{}在结果对象中引用(例如:$obj->prop->{4}->prop)
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 $object;
}
这将把yaml配置为
fields:
abc:
type: formfield
something:
- a
- b
- c
- d:
foo:
bar
到由以下数组组成的数组:
array:1 [
"fields" => array:1 [
"abc" => array:2 [
"type" => "formfield"
"something" => array:4 [
0 => "a"
1 => "b"
2 => "c"
3 => array:1 [
"d" => array:1 [
"foo" => "bar"
]
]
]
]
]
]
以…为目标:
{#325
+"fields": {#326
+"abc": {#324
+"type": "formfield"
+"something": array:4 [
0 => "a"
1 => "b"
2 => "c"
3 => {#328
+"d": {#327
+"foo": "bar"
}
}
]
}
}
}
我使用的一个(它是类成员):
const MAX_LEVEL = 5; // change it as needed
public function arrayToObject($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;
}
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);
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; }
