foreach 循环中的两个数组 [英] Two arrays in foreach loop

问题描述

我想使用两个数组生成一个 selectbox，一个包含国家代码，另一个包含国家名称.

I want to generate a selectbox using two arrays, one containing the country codes and another containing the country names.

这是一个例子:

<?php
    $codes = array('tn','us','fr');
    $names = array('Tunisia','United States','France');

    foreach( $codes as $code and $names as $name ) {
        echo '<option value="' . $code . '">' . $name . '</option>';
    }
?>

这个方法对我不起作用.有什么建议吗?

This method didn't work for me. Any suggestions?

推荐答案

foreach( $codes as $code and $names as $name ) { }

这是无效的.

你可能想要这样的东西......

You probably want something like this...

foreach( $codes as $index => $code ) {
   echo '<option value="' . $code . '">' . $names[$index] . '</option>';
}

或者，将代码作为 $names 数组的键会容易得多...

Alternatively, it'd be much easier to make the codes the key of your $names array...

$names = array(
   'tn' => 'Tunisia',
   'us' => 'United States',
   ...
);
