PHP正则表达式以匹配模式\\\\ domain \\ username

Question

I'm trying to match a string in the format of \\domain\\username using PHP and I can't get it to return the matched pieces in an array.

$username = "\\domain\jason";    
$login = preg_match_all("/^\\\\[a-z0-9\-]+\\[a-z0-9\-]+$/i", $username, $found);
    var_dump($found);
    array
      0 => 
        array
          empty

I tested my regular expession with an online tester and it matched the string perfectly.

Answer 1

You can use this code:

$username = "\\domain\jason";
if (preg_match_all('~\\\\?(\w+)~', $username, $arr))
   print_r($arr[1]);

OUTPUT:

Array
(
    [0] => domain
    [1] => jason
)

Answer 2

If you know the fields are separated by a \\ just do this:

$username = '\\domain\jason';

$arr = explode('\\', $username);

echo $arr[1]; // domain
echo $arr[2]; // jason
