I have two strings:
我有两个字符串：
email-info and info/email

This is pretty trivial for regular expressions. That is to say you could use something else (i.e. string functions).
这对于正则表达式来说非常简单。也就是说你可以使用别的东西（即字符串函数）。
Nonetheless, here's an example using preg_split():
尽管如此，这是使用preg_split（）的示例：
$parts = preg_split('/[-\/]/', $string);

Jason's right. Here's a way to do it with string functions:
杰森是对的。这是使用字符串函数执行此操作的方法：
$str1 = "email-info";
$result = substr($str1, 0, strlen($str1) - strpos('-'));

You can use PHP's split method
您可以使用PHP的split方法
$StringYouWant = split($StringNeedsSplitting, '(-|/)')[0]
