如何通过PHP从字符串中获取子字符串? [英] How to get a substring from string through PHP?

问题描述

您想将显示的用户名(例如[e-mail])更改为仅abcd. 所以为此，我应该剪切从@开始的部分.

Hi want to change the displayed username like [e-mail] to only abcd. so for this i should clip the part starting from @.

我可以通过Java或C#中的variablename.substring()函数非常轻松地完成此操作，但是我不了解PHP的语法. 所以帮我做到这一点.

I can do this very easily through variablename.substring() function in Java or C# , but I m not aware with the syntax of PHP. So help me do that .

假设我有类似的变量.

$username = "[e-mail]";
$username = some

字符串操作函数应该在这里调用； 以便 echo $ username; 只能产生abcd.

string manipultion functiona should get called here ; so that echo $username; can results in abcd only.

推荐答案

尝试一下:

$username = substr($username, 0, strpos($username, '@'));
