Can't store data to mySQL [duplicate]

Im trying to store form data on mySQL but for some reason, i'm getting an error on my 7th line of code which is Parse error: syntax error, unexpected 'if' (T_IF) in C:\xampp\htdocs\testdata\register.php on line 7

on if($_POST['first_name'] != "" && $_POST['last_name'] != "" && $_POST['email'] != "") {

I've done some research on the error, most people are mentioning that it's something got to do with a missing semicolon but i dont think a semicolon is missing in the code but would be great if someone can look at it also.

my entire code:

<?php     session_start();        include_once("db.php"); // includes the db file into this page.        if($_POST['first_name']) ($_POST['last_name'] ($_POST['email'])) {          if($_POST['first_name'] != "" && $_POST['last_name'] != "" && $_POST['email'] != "") {              $first = $_POST['first_name'];              $last = $_POST['last_name'];              $mail = $_POST['email'];              $sql_store = "INSERT into names (id, first, last, email) VALUES (NULL, '$first', '$last', '$mail' )";              $sql = mysqli_query($db, $sql_store) or die(mysql_error());          } else {              echo "You need to to enter data in the boxes. ";          }      } else {          echo "You need to to enter data in the boxes. ";      }  ?>
