在PHP中对包含单词和数字的数组进行排序

Question

I have an array in PHP containing word "Paying" and years like this:

Array
(
    [0] => 2014
    [1] => 'Paying'
    [2] => 2013
    [3] => 2015 
)

I want to short it so the "Paying" will always be the first following by descending order of years

Array
(
    [0] => 'Paying'
    [1] => 2015
    [2] => 2014
    [3] => 2013
)

What is the simple way to do it in php? Thanks.

Answer 1

This should work for you:

(Here i simple use rsort())

<?php

    $arr = array(2014, "Paying", 2013, 2015);

    print_r($arr);
    rsort($arr, SORT_STRING);
    print_r($arr);

?>

Output:

//Before
Array ( [0] => 2014 [1] => Paying [2] => 2013 [3] => 2015 )

//After
Array ( [0] => Paying [1] => 2015 [2] => 2014 [3] => 2013 )
