如何提取字符串中“@"字符前面的所有文本 [英] How to extract all text in front of the '@' character in a string

问题描述

如何删除以@"开头的字符串?

how to remove a string starting from '@'?

例如[e-mail]，我想删除以@ 开头的字符串，使其仅成为admin".就像在 twitter..我读过 str 替换和修剪，但我认为还有其他方法可以做到吗?

for example [e-mail], i want to remove the string starting from @ so it becomes 'admin' only. just like in twitter..i read about str replace and trim but i think theres other way to do it?

$email = '[e-mail]';

echo substr_replace($email, ?, ?) ; this i cant do

推荐答案

余数不需要替换，只要剪掉搜索到的字符即可.在这种情况下，使用 strtok 非常容易:

You don't need to replace the remainder, you can just cut out until the searched character. In this case it's very easy with strtok:

 $name = strtok($email, "@");
