在 PHP 中显示数组值 [英] Display array values in PHP

问题描述

所以，我是第一次使用 PHP，我正在尝试检索和显示数组的值.经过大量的谷歌搜索，我能找到的唯一方法是 print_r、var_dump 或 var_export.但是，所有这些方法都返回如下所示的内容:

So, I'm working with PHP for the first time and I am trying to retrieve and display the values of an array. After a lot of googling, the only methods I can find for this are print_r, var_dump or var_export. However, all of these methods return something that looks like this:

[a] => apple
[b] => banana
[c] => orange

我不知道如何设计这个outout.我需要去掉 [a] => 部分并添加逗号.我知道这一定是一个非常简单的过程，但我无法找到任何演示如何执行此操作的文档.

I can't figure out how to style this outout. I need to strip away the [a] => part and add commas. I know this must be a pretty straightforward process but I haven't been able to track down any documentation that demonstrates how to do it.

推荐答案

有 php 中的 foreach 循环.你必须遍历数组.

There is foreach loop in php. You have to traverse the array.

foreach($array as $key => $value)
{
  echo $key." has the value". $value;
}

如果您只是想在值之间添加逗号，请考虑使用 implode

If you simply want to add commas between values, consider using implode

$string=implode(",",$array);
echo $string;
