Php使用正则表达式查找字符串的一部分

Question

I want to get a the part of string of an email after @ using regular expression. For example, I have the string '[e-mail]' and i want to get 'gmail.com'. I wrote /^@./ but doesn't work- I wrote

preg_match('/^@./', $string, $output);
print($output);

How can i fix it?

Answer 1

Why regex for this kind of simple task? use strpos with the combination of substr or just used explode() with @ as first parameter as directed by other answers.

$email_string = "[e-mail]";    
$result = substr($email_string, strpos($email_string, "@") + 1);    
echo $result ;
