Update an array
提问by James
$varis an array:
$var是一个数组：
Array (
[0] => stdClass Object ( [ID] => 113 [title] => text )
[1] => stdClass Object ( [ID] => 114 [title] => text text text )
[2] => stdClass Object ( [ID] => 115 [title] => text text )
[3] => stdClass Object ( [ID] => 116 [title] => text )
)
Want to update it in two steps:
想分两步更新：
- Get
[ID]of each object and throw its value to position counter (I mean[0], [1], [2], [3]) - Remove
[ID]after throwing
- 获取
[ID]每个对象并将其值抛出到位置计数器（我的意思是[0], [1], [2], [3]） [ID]投掷后移除
Finally, updated array ($new_var) should look like:
最后，更新后的数组 ( $new_var) 应如下所示：
Array (
[113] => stdClass Object ( [title] => text )
[114] => stdClass Object ( [title] => text text text )
[115] => stdClass Object ( [title] => text text )
[116] => stdClass Object ( [title] => text )
)
How to do this?
这该怎么做？
Thanks.
谢谢。

$new_array = array();
foreach ($var as $object)
{
$temp_object = clone $object;
unset($temp_object->id);
$new_array[$object->id] = $temp_object;
}
I'm making the assumption that there is more in your objects and you just want to remove ID. If you just want the title, you don't need to clone to the object and can just set $new_array[$object->id] = $object->title.
我假设您的对象中有更多内容，而您只想删除 ID。如果您只想要标题，则无需克隆到对象，只需设置$new_array[$object->id] = $object->title.

I'd have thought this would work (have no interpreter access, so it might require tweaking):
我原以为这会起作用（没有解释器访问权限，因此可能需要调整）：
<?php
class TestObject {
public $id;
public $title;
public function __construct($id, $title) {
$this->id = $id;
$this->title = $title;
return true;
}
}
$var = array(new TestObject(11, 'Text 1'),
new TestObject(12, 'Text 2'),
new TestObject(13, 'Text 3'));
$new_var = array();
foreach($var as $element) {
$new_var[$element->id] = array('title' => $element->title);
}
print_r($new_var);
?>
Incidentally, you might want to update your variable naming conventions to something more meaningful. :-)
顺便说一句，您可能希望将变量命名约定更新为更有意义的内容。:-)
