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

问题描述

所以，我用PHP工作的第一次，我试图来检索和显示数组的值。很多谷歌搜索后，唯一的方法我可以找到这个是的print_r ，的var_dump 或 var_export 。然而，所有这些方法返回的东西，看起来像这样：

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

我无法弄清楚如何风格这个outout。我需要抛开 [A] =＆GT; 部分并添加逗号。我知道这一定是pretty简单的过程，但我一直无法追查演示如何做的文档。

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 循环在PHP。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;
}

如果您只是想值之间添加逗号，请考虑使用破灭

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

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