title: MySQL-Querys aren't working? (PHP)
body: <p>So, in my MySQL-Database in "Posts" I have "ID" and "Likes".
  In the line where the value of ID is 3, the value of Likes is 6.</p>
  
  <p>When I do:</p>
  
  <pre><code>$postId = 3;
  $connection = mysql_connect(...);
  $query = "SELECT * FROM Posts Where ID=".$postID;
  $result = mysql_query($query);
  $row = mysqli_fetch_array($result);
  $likes = $row['Likes'];
  echo $likes;
  </code></pre>
  
  <p>But this just returns nothing. When I try to print_r the $row, it also return nothing,
  but the connections etc. is right. What's my mistake I made?</p>
