Hello
I found this function online and want to understand how it works.
I don't understand "/^" and "$/". I know that "^" beginning of the string but what is "/^".
Thanks
function validEmail($email)
{
return preg_match("/^([a-zA-Z0-9])+([.a-zA-Z0-9_-])*@([a-zA-Z0-9_-])+(.[a-zA-Z0-9_-]+)+[a-zA-Z0-9_-]$/",$email);
}
