$len=strlen($string);

$num=0; for($i=0;$i<$len;$i++) { if(in_array($string[$i],$vowels)) { $num++; } } echo "Number of vowels: $num
"; $len=$len-1; echo "Number of characters: $len
"; $word=str_word_count($string); echo "Number of words: $word
"; $line=substr_count($_POST['str'],"\n"); echo "Number of lines: $line"; } ?>

4. Develop a simple calculator web application that takes 2 numbers and an operator (+,-,, /,%) from an HTML page and returns the result.*

Username:

{ echo "Failed to connect with the server"; exit(); } else { $uname=$_POST['uname']; $pass=$_POST['pass']; $q="select Message from users where Username='$uname' and Password='$pass'"; $result=$conn->query($q); if($result->num_rows>0) { $row=$result->fetch_assoc(); echo "Message ".$row['Message']; } else { echo "Either username or password is wrong"; } } } ?>
