php array key sorting with strings & numbers

本文关键字：字符串数字排序数组 PHP | 更新日期: 2023-09-27

<?php
$rate=array ( "M100B1000" => "40.00", "M1000B20000" => "80.00", "M500B10000" => "50.00", "MUnlimitedBUnlimited" => "240.00", "M5000BUnlimited" => "120.00 ") ;
ksort($rate);
print_r($rate);
?>

它给出了排序率数组。

M1000B20000
M100B1000
M5000BUnlimited
M500B10000
MUnlimitedBUnlimited

我需要这种排序..

M100B1000
M500B10000
M1000B20000
M5000BUnlimited
MUnlimitedBUnlimited

给出一些想法...

看起来您想根据字符串的大小对其进行排序，如果是，请查看此示例

 function shortestFirst(key($str1), key($str2)) {
        return strlen(key($str1)) - strlen(key($str2));
     }
    $rate=array ( "M100B1000" => "40.00", "M1000B20000" => "80.00", "M500B10000" => "50.00", "MUnlimitedBUnlimited" => "240.00", "M5000BUnlimited" => "120.00 "); 

    uasort($data, 'shortestFirst');
        print_r($data);
        echo '</pre>';
