如何删除字符串中第一个特定字符之前的所有内容? [英] How to remove everything before the first specific character in a string?

问题描述

我的变量如下:

AAAAAAA，BB CCCCCCCC

AAAA，BBBBBB CCCCCC

我想删除","之前的所有内容，

I would like to remove everything before the ",",

因此结果应如下所示:

BB CCCCCCCC

BBBBBB CCCCCC

我已经解决了此问题，以便删除","之后的所有内容:

I have worked out this to remove everything AFTER the ",":

list($xxx) = explode(',', $yyyyy);

不幸的是，我不知道如何删除","之前的所有内容.

unfortunately I dont know how to get it to work to remove everything BEFORE the ",".

推荐答案

我不建议使用explode，因为如果有多个逗号，则会引起更多问题.

I wouldn't recommend using explode, as it causes more issues if there is more than one comma.

// removes everything before the first ,
$new_str = substr($str, ($pos = strpos($str, ',')) !== false ? $pos + 1 : 0);

if(($pos = strpos($str, ',')) !== false)
{
   $new_str = substr($str, $pos + 1);
}
else
{
   $new_str = get_last_word($str);
}
