如何使用php和mysql成功转义撇号[复制]

I know this has been asked many times before but I'm still stumped. I'm obviously missing something but I have been unable to figure out how to successfully escape the apostrophe when sending a mysql query from php. Why does this not work when everything I have read says it should.

<?php
$title = "havin' fun";
$con=mysqli_connect($server,$username,$password,$database);
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
 $title = mysqli_real_escape_string($title); 
 $result = mysqli_query($con,"SELECT id,artist,title FROM songs WHERE title     = '$title'");
if($result) {
    while($row = mysqli_fetch_assoc($result)) {
    $id = $row['id'];   
    $artist = $row['artist'];
    $title = $row['title'];
    echo $id.' - '.$artist.' - '.$title.'<br>';
    }
}else echo 'No Results';
mysqli_close($mysqli);
?>

</div>

 $title = mysqli_real_escape_string($title);// add another parameter for connection 

For example:

  $title = mysqli_real_escape_string($conn, $title)
