如何在php中将数组项放到最后？

Question

how to put an array item to the end in php?
I want to put some item of array to the last position , when I loop and output the $arr to html, this will keep the 'other' item always at the end. what is the best and easy way to do it?

<?php
$arr=array(
    'a'=>'hello',
    'game'=>'boy',
    'other'=>'good',
    'name'=>'jimmy',
    //...
);


// how to resort $arr to put other item to then end of $arr
$arr=array(
    'a'=>'hello',
    'game'=>'boy',
    'name'=>'jimmy',
    //...
    'other'=>'good'
);
?>

Answer 1

Assuming you're not simply asking to sort the array based on the alphabetical property of the keys, given your array:

$arr=array(
    'a'=>'hello',
    'game'=>'boy',
    'other'=>'good',
    'name'=>'jimmy',
);

You have to take the old key out first, while saving its value:

$old = $arr['other'];
unset($arr['other']);

Then, append it to the array like this:

$arr += array('other' => $old);
