move元素，带有白色阵列中的键到阵列末端的键[重复]

Question

我有以下数组，并且会不时改变。

Array
(
    [For Sale] => For Sale
    [Sold] => Sold
    [To Let] => To Let
    [Let] => Let
    [Under Offer] => Under Offer
    [Exchanged] => Exchanged
    [Withdrawn] => Withdrawn
    [Acquired] => Acquired
)

不管最初的序列是什么，但是当页面加载时，它应该看起来像

Array
    (
        [For Sale] => For Sale       
        [Under Offer] => Under Offer
        [Exchanged] => Exchanged
        [Withdrawn] => Withdrawn
        [Acquired] => Acquired
        [Sold] => Sold
        [To Let] => To Let
        [Let] => Let
    )

基本上，这三个要素应该留在数组的底部。

[Sold] => Sold
[To Let] => To Let
[Let] => Let

在此处，我已经使用

Answer 1

将键与给定的键匹配，然后从

'Sold','To Let','Let'

数组中解开该键，然后将该键值推到数组中。

$input这将输出：

<?php
$input = array(
    'For Sale' => 'For Sale',
    'Sold' => 'Sold',
    'To Let' => ' To Let',
    'Let' => 'Let',
    'Under Offe' => 'Under Offer',
    'Exchanged' => 'Exchanged',
    'Withdrawn' => 'Withdrawn',
    'Acquired' => 'Acquired'
);

foreach ($input as $key => $val) {
    if (in_array($key, array('Sold', 'To Let', 'Let'))) {
        unset($input[$key]);
        $input[$key] = $val;
    }
}

echo "<pre>";
print_r($input);
?>

llet您的数组名称为

Array
(
    [For Sale] => For Sale
    [Under Offe] => Under Offer
    [Exchanged] => Exchanged
    [Withdrawn] => Withdrawn
    [Acquired] => Acquired
    [Sold] => Sold
    [To Let] =>  To Let
    [Let] => Let
)

。 首先将值存储在变量中，然后将它们放置，然后使用

$arr

将它们存储在数组的最后一个。

Answer 2

您必须使用foreach格式化数据。

$sold = $arr['Sold'];
unset($arr['Sold']);

$to_let = $arr['To Let']; 
unset($arr['To Let']);

$let = $arr['Let']; 
unset($arr['Let']);

array_push($arr, $sold, $to_let, $let);

使用“自定义顺序”（几个维度排序）使用

Answer 3

函数的有效解决方案：

array_multisort输出：

Answer 4

// $arr is your initial array
$custom_order = ['F'=> 0,'S' => 5,'T' => 6,'L' =>7,'U' => 1,'E' => 2,'W' => 3,'A' => 4];
array_multisort($custom_order, SORT_ASC, $arr);

print_r($arr);

使用

Array
(
    [For Sale] => For Sale
    [Under Offer] => Under Offer
    [Exchanged] => Exchanged
    [Withdrawn] => Withdrawn
    [Acquired] => Acquired
    [Sold] => Sold
    [To Let] => To Let
    [Let] => Let
)

和

uksort

函数或另一种（甚至更好）的方法：

array_search
