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"
)

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);
}
其他回答
我用了很简单的方法,
$list_years = array();
$object = new stdClass();
$object->year_id = 1 ;
$object->year_name = 2001 ;
$list_years[] = $object;
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;
}
}
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($ArrToObject);
结果将是一个包含数组的对象:
对象(stdClass)#1048(2){[128]=>数组(1){ ["地位"]= > 字符串(87)“图a: Facebook的水平滚动条显示在1024x768分辨率的屏幕上。”} [129]=>数组(1){ ["地位"]= > 字符串(44)“前几天上班,我有一些空闲时间”}}
这个方法对我很管用
function array_to_obj($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;
}
你也可以使用ArrayObject,例如:
<?php
$arr = array("test",
array("one"=>1,"two"=>2,"three"=>3),
array("one"=>1,"two"=>2,"three"=>3)
);
$o = new ArrayObject($arr);
echo $o->offsetGet(2)["two"],"\n";
foreach ($o as $key=>$val){
if (is_array($val)) {
foreach($val as $k => $v) {
echo $k . ' => ' . $v,"\n";
}
}
else
{
echo $val,"\n";
}
}
?>
//Output:
2
test
one => 1
two => 2
three => 3
one => 1
two => 2
three => 3
