I'm fairly new to both Unity and PHP, and I am currently working on a project where I can parse data from a MySQL database to Unity, using PHP.

I initially wanted to try and enable a method where the user can perhaps change the php script and enable it to choose a different table of data, however I was advised that it may be safer to list all variables within the php script and call it from Unity accordingly;

Display.php
Code:
$table = mysql_real_escape_string($_GET['table'], $db);

if ($table == "shoes") { 
$query = "SELECT * FROM `shoes` ORDER by `price` ASC LIMIT 10";

elseif ($table == "sneakers") { 
$query = "SELECT * FROM `sneakers` ORDER by `price` ASC LIMIT 10";

$result = mysql_query($query) or die('Query failed: ' . mysql_error());
$num_results = mysql_num_rows($result);  

for($i = 0; $i < $num_results; $i++)
  {
       $row = mysql_fetch_array($result);
       echo $row['shopname'] . "\t" . $row['price'] . "\n";
  }
?>
I'm having trouble calling the php and choosing the table that I want to select, I am pretty new to this, so I apologise if this seems completely incompetent to you guys.

Here is the my Unity Script;

HSController.cs

Code:
void Start()
{
    StartCoroutine(GetScores());
}

// remember to use StartCoroutine when calling this function!
IEnumerator PostScores(string name, int score)
{


    string hash = Md5Sum(name + score + secretKey);

    string post_url = addScoreURL + "name=" + WWW.EscapeURL(name) + "&score=" + score +   "&hash=" + hash;

    WWW hs_post = new WWW(post_url);
    yield return hs_post; // Wait until the download is done

    if (hs_post.error != null)
    {
        print("There was an error posting the high score: " + hs_post.error);
    }
}


IEnumerator GetScores()
{
    gameObject.guiText.text = "Loading...";
    WWW hs_get = new WWW(highscoreURL);
    yield return hs_get;

    if (hs_get.error != null)
    {
        print("There was an error getting the high score: " + hs_get.error);
    }
    else
    {
        gameObject.guiText.text = hs_get.text; // this is a GUIText that will display the scores in game.
        }
    }

}
Any help or a point in the right direction would be great!

Kind Regards
