title: How do I count query result rows?
body: <p>What should I replace 'CODE TO VERIFY IF QUERY RESULT ROW IS = 1' for?<br>
  I've tried many ways using num_rows but it won't work.
  <br><br> My PHP code:
      
  
  <pre><code>    $con=mysqli_connect("localhost","mbrconsu_un394x","y1cz9,rd+hf6","mbrconsu_mmx");
  
      if (mysqli_connect_errno($con))
      {
          echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }
  
      $usuario = $con-&gt;real_escape_string($_GET['usuario']);
      $senha = $con-&gt;real_escape_string($_GET['senha']);
  
          $query = mysqli_query($con, "SELECT * FROM 'login' WHERE usuario = '$usuario' AND senha='$senha'");
  
          if(CODE TO VERIFY IF QUERY RESULT ROW IS = 1){
              while($row = mysqli_fetch_assoc($query)){
                  $db_username = $row['usuario'];
                  $db_password = $row['senha'];
              }
              if($usuario == $db_username &amp;&amp; $senha == $db_password){
                  return true;
              }
              } else {
              return false;
          }
  
      mysqli_close($con);
  ?&gt;
  </code></pre>
