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"
)

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>';
?>

这个方法对我很管用
function array_to_obj($array, &$obj)
{
foreach ($array as $key => $value)
{
if (is_array($value))
{
$obj->$key = new stdClass();
array_to_obj($value, $obj->$key);
}
else
{
$obj->$key = $value;
}
}
return $obj;
}
function arrayToObject($array)
{
$object= new stdClass();
return array_to_obj($array,$object);
}
用法:
$myobject = arrayToObject($array);
print_r($myobject);
返回:
[127] => stdClass Object
(
[status] => Have you ever created a really great looking website design
)
[128] => stdClass Object
(
[status] => Figure A.
Facebook's horizontal scrollbars showing up on a 1024x768 screen resolution.
)
[129] => stdClass Object
(
[status] => The other day at work, I had some spare time
)
像往常一样,你可以这样循环:
foreach($myobject as $obj)
{
echo $obj->status;
}

<?php
//defining an array

//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>';
?>
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;
}
根据你需要的位置和访问对象的方式有不同的方法。
例如:只需对它进行类型转换
$object = (object) $yourArray;
然而,最兼容的方法是使用一个实用程序方法(还不是PHP的一部分),它实现了基于指定类型的字符串的标准PHP强制转换(或者忽略它,只是去引用值):
/**
* dereference a value and optionally setting its type
*
* @param mixed $mixed
* @param null $type (optional)
*
* @return mixed $mixed set as $type
*/
function rettype($mixed, $type = NULL) {
$type === NULL || settype($mixed, $type);
return $mixed;
}
您案例中的使用示例(在线演示):
$yourArray = Array('status' => 'Figure A. ...');
echo rettype($yourArray, 'object')->status; // prints "Figure A. ..."
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。
