PHP：基于其他字符串

Question

我想获得分割零件的值从字符串爆炸的数据。

我的代码是：

<?php 
$password = "03,10,05,07,17,23"; 

$string = "::3:8:1::5::2:9::::6:::4::::::0:"; 

$string = explode(':', $string); 

如何通过$密码

$字符串[03]，$字符串[10]，$字符串[05]，$字符串的顺序执行打印$字符串[07]，$字符串[17]，$字符串[23]

结果极品：391540

在这里，你去Live demo

$password = "03,10,05,07,17,23"; 

$string = "::3:8:1::5::2:9::::6:::4::::::0:"; 

$pass = explode(',', $password); 
$code = explode(':', $string); 

$result = ''; 
foreach ($pass as $pos) { 
    $pos = ((int)$pos)-1; 
    $result .= $code[$pos]; 
} 

echo $result;
