body: <p>I try to count the number of rows in my query, but I get the error message:</p>
  
  <p>Fatal error: Call to undefined function Â mysqli_num_rows() in </p>
  
  <p>My code is:</p>
  
  <pre><code>$query2 = "SELECT `vraag` FROM `log` WHERE `nam` = '3' AND `status` = '0' LIMIT 1"; 
  $sql2 = mysqli_query($con,$query2) or die("could not perform query");
  $record2 = mysqli_fetch_assoc($sql2);
  $aantal = mysqli_num_rows($sql2);
  </code></pre>
  
  <p>Does anybody know what is wrong in this code?
  Thanks in advance. </p>
