php - 2个带有数组的foreach循环

问题描述

我想要做的是让我的“$ages”数组按数组的顺序为每个玩家显示一个值。但是每次我用该数组添加额外的 for 循环时，它都会复制每个玩家 20 次，每次数组值一次。我想要 20 个玩家，每个数组有 20 个不同的值。

这是当前的输出，即复制每个玩家 20 次。 http://freerdarts.com/test.php

这是代码

解决方案

问题是你foreach()的显示部分有一个内部......

foreach($ages as $age) {

这似乎与您正在显示的数据没有任何关系，因为数据中似乎没有年龄。

您还应该收到一些警告

$ages = array(one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve,thirteen,fourteen,fifteen,sixteen,seventeen,eighteen,nineteen,twenty);

将会呈现

警告：使用未定义的常量一 - 假定为“一”（这将在 PHP 的未来版本中引发错误）您应该在值周围加上引号...

$ages = array('one',...

如果你只想列出对应年龄的球员，你首先需要改变

foreach($combined as $key => $row) {
// Remove next foreach
// foreach($ages as $age) {

然后显示年龄，使用 $keyforeach()来索引$ages数组...

<span class="age"><?=$ages[$key];?></span>
