Question

Got this script partially working, but if there are 3 tags on 1 video, and I type all 3 tags, the video comes back 3 times, not sure how to rectify this.

$search = sanitize($_GET['search']);
$array = explode(" ", $search);
foreach($array as $mySearch)
{
  $query = mysql_query("SELECT * FROM `videos`");
  while($mad = mysql_fetch_array($query))
  {
    if(strpos($mad['tags'], $mySearch))
    {
      // show results
      echo "<div class='comment_1'>$mad[title]</div>";
    }
  }
}

Any help is always greatly appreciated.

Got this script partially working

Well that’s fine, however, scripts are like being pregnant: There is no partially. A system either works or not, not much between the lines.

You have a logical problem here, resulting from a wrong order of processing with your control structures.

The normal procedure is:

1. Validate and process the input data.
2. Work with the data, transform it. In your case, use it to fetch data from the database.
3. Output the data fetched from the store.

In your script you mix all these three things into each other instead of doing one part after the other:

$tags_array = get_tags_array_from_input();

$result = mysql_query_result_based_on_tags_array($tags_array);

display_results($result);

/**
 * exemplary only
 */
function mysql_query_result_based_on_tags_array(array $tags)
{
    $mask = "SELECT * FROM videos WHERE tags REGEXP '%s'";
    $sql  = sprintf($mask, implode('|', $tags));

    return mysql_query($sql);
}
