title: Problem when trying to send a query consists of 2 command to Mysql database
body: <p>I get the following error when trying to DELETE from my tables:
  Error: DELETE FROM table1 WHERE ID='K0D4iJ0aEzHJh03'; DELETE FROM table2 WHERE ID='K0D4iJ0aEzHJh03'</p>
  
  <p>I've tried to put the query to workbench, and it's working flawless. If I try to send only 1 line 
  DELETE from table1 WHERE ID='K0D4iJ0aEzHJh03';
  OR
  DELETE from table2 WHERE ID='K0D4iJ0aEzHJh03';
  It's working flawless.</p>
  
  <pre><code>$sql="DELETE FROM table1 WHERE ID='$ID';
  DELETE FROM table2 WHERE ID='$ID'";
  }
  if ($con-&gt;query($sql) === TRUE) {
  echo "Your request has been succesfully made.";
  } else {
  echo "Error: " . $sql . "&lt;br&gt;" . $conn-&gt;error;
  }
  </code></pre>
