title: If statement or while loop failing on me in php
body: <p>I am fairly new to coding in php and have come accross a bit of a problem which I think is very simple. I am trying to capture the IP address of anybody that visits my website and stores that in my database. The code is as follows, I am not even sure the code will work but I do get the following error Parse error: syntax error, unexpected T_INC on line 29 which I will highlight in the code:</p>
  
  <pre><code>$ip = $_SERVER['HTTP_CLIENT_IP']; 
                  $query="SELECT * FROM ip";
                  $result = mysql_query($query);
                  $num = mysql_numrows($result);
                  $i = 1;
                  $found=false;
                  while(($i - 1) &lt; $num){
                      $selection = mysql_query("SELECT ip FROM ip WHERE id=$i");
                      $tip = mysql_fetch_assoc($selection);
                      if($tip == $ip){
                          $found = true;
                      }
                  i++; //This is line 29
                  }
                  if($found == false){
                      $sql = "INSERT INTO `rowley_blog`.`ip` (`ip`) VALUES ('$ip');";
                      mysql_query($sql);
                      mysql_close();
                  }
  </code></pre>
