Reorder the elements in an array using php

I have the following array and it is changeable from time to time. 

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    [Withdrawn] =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 Withdrawn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

No matter what's the initial sequence was but when the page loads it should look like 

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        [Withdrawn] =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 Withdrawn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

Basically these three elements should stay at the bottom of the array.

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

Any help is highly appreciated. Thanks in advance.

Here I've used in_array() to match the key with the given keys 'Sold','To Let','Let', then unset that key from $input array and push that key value to the array.

<?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    'Withdrawn' =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 'Withdrawn',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);
?>

This will Output : 

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    [Withdrawn] =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 Withdrawn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

Short and effective solution using array_multisort function with "custom order"(few dimensions sorting):

// $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);

The output:

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    [Withdrawn] =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 Withdrawn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

Or another(even better) approach using uksort and array_search functions:

$custom_order = ['For Sale','Under Offer','Exchanged','Withdrawn','Acquired','Sold','To Let','Let'];
uksort($arr, function($a, $b) use($custom_order){
    return array_search($a,$custom_order) - array_search($b,$custom_order);
});

You must format your data using foreach.

$data = [
 'For Sale' => For Sale
 'Sold' => Sold
 'To Let' => To Let
 'Let' => Let
 'Under Offer' => Under Offer
 'Exchanged' => Exchanged
 'Withdrawn' => Withdrawn
 'Acquired' => Acquired
];

$newData = [];

foreach($data as $key => $val) {
   $newData[] = [
       'For Sale' => $val['For Sale'],
       'Under Offer' => $val['Under Offer'],
       'Exchanged' => $val['Exchanged'],
       'Withdrawn' => $val['Withdrawn'],
       'Acquired' => $val['Acquired'],
       'Sold' => $val['Sold'],
       'To Let' => $val['To Let'],
       'Let' => $val['Let']
   ]
}

print_r($newData);

Let you array name is $arr. First store the values in a variable and then unset them, after that use array_push to store them at the last of the array.

$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);
