I currently working on a game i am building...

Notice: Undefined offset: 1 in C:\Users\AJ\Downloads\USBWebserver v8.5\USBWebserver v8.5\8.5\root\global_reg.php on line 68

else
              {
              $email = explode("@", $_GET['string']);
              $check_for_the_dot = explode(".", $email[1]);
              if(substr_count($_GET['string'], "@") > '1')
              { 
                  echo "<font color='white'><b>No more than one \"@\".</b></font>";
                  exit(); 
              }
              if(!$check_for_the_dot[1])
              { 
                  echo "<font color='white'><b>Email address will be verified.</b></font>";
                  exit(); 
              }

 

Line 68 is : $check_for_the_dot = explode(".", $email[1]);

Line 74 is :if(!check_for_the_dot[1])

Would this work for Line 74

if (isset(!check_for_the_dot[1]))
 !check_for_the_dot = substr(!check_for_the_dot[1]);

or you can just use filter_var() or filter_input() which is a whole lot easier

You said it yourself - undefined offset.

If there is only 1 result, given arrays start at 0, you need $check_for_the_dot[0]

With that said, you could also just use a function that google could return using a search term like "php email validation"

now that you got that figured out you should validate correct characters

With false positives from filter_var?

With false positives from filter_var?

Not necessarily no. But with filter var that would have checked for the @ and the '.' he was seeking right? Now I'm sure you can do some other high tech regex pattern because the filter_validate_email type does allow a range of chars that you would not normally see in an email address or a super long prefix to the email domain.

so are you saying if(!isset(check_for_the_dot[0]))
