从字符串中删除第一个和最后一个字符 [英] Remove first and last char from string

问题描述

我有这个:

$dataList = "*one*two*three*";
$list = explode("*", $dataList);
echo"<pre>";print_r($list);echo"</pre>";

输出:

> Array (
>     [0] => 
>     [1] => one
>     [2] => two
>     [3] => three
>     [4] =>  )

如何在爆炸前去掉字符串中的第一个和最后一个 *?

How do I strip the fist and last * in the string before exploding?

推荐答案

Using trim:

Using trim:

trim($dataList, '*');

这将删除字符串末尾和开头的所有 * 字符(即使有多个！).

This will remove all * characters (even if there are more than one!) from the end and the beginning of the string.
