You can use WWW to open any url you want, including your typical get parameters (e.g. http://myserver.com/?action=getData) www.data will contain the received data as a string. So you can write you own php code, that will return the reqired data in a format that you can easily parse. To parse the returned data you can use the standard .net string features, or you return xml and use .net's xml parsing functions.

This is how i ended up doing it, hopefully it can serve as an example for somone else =)

function Start() 

{ // show the progress window showProgress=true;

var w = WWW(URL);
yield w; 
planetData = w.data; //here we return the data our PHP told us

var singlecoords = planetData.Split("\n"[0]); //line splitting php outut

curLine=0;
maxLines=singlecoords.Length;

for (line in singlecoords) 
{
    // advance progress indicator
    ++curLine;
    var coords = line.Split(","[0]); //taking xyz & other data from singlecoords
    if (line.Length >= 8) {
        // makes sure we only instantiate valid planet records and
        // not any blanks the PHP/web exchanger added to the end
        planetID = parseInt(coords[0]);
        planetName = coords[6];
        planetOwner = coords[4];
        planetSector = coords[5];
        objectType = parseInt(coords[7]);

        var pos = Vector3(parseInt(coords[1]),parseInt(coords[2]),parseInt(coords[3]));

        if (ObjectFactories.Length>objectType && ObjectFactories[objectType] != null) {
            var planetInstance = Instantiate(ObjectFactories[objectType], pos, Quaternion.identity);
            planetInstance.name = planetName;

        switch (objectType) {
            case 0: /* Planet */
                pInfo=planetInstance.GetComponent(PlanetClick);
                pInfo.planetName=planetName;
                pInfo.planetSector=planetSector;
                pInfo.planetOwner=planetOwner;
                pInfo.planetID=planetID;
                pInfo.objectType=objectType;
                break;

            case 1: /* Asteroid Belt */
            print(objectType);
                pInfo=planetInstance.GetComponent(PlanetClick);
                pInfo.planetName=planetName;
                pInfo.planetSector=planetSector;
                pInfo.planetOwner=planetOwner;
                pInfo.planetID=planetID;
                pInfo.objectType=objectType;
                break;

            default:
                print("No initializer for object type "+objectType);
        }

        } else {
            print("No prefab template in objectType slot "+objectType);
        }
    }
}

Question: Can i use this way to read fetched data from php/MYSQL Db.

code in my unity .js file.

var hs_get : WWW = new WWW (url); yield hs_get; var newdata = hs_data.data; . . .

does this mean , "newdata" has all the attributes as in the database table fetched from DB using PHP?

Please note. This might fail strangely and silently. Check if there is difference between receiving hard coded and dynamic data using this php code:

this is hard coded text and will usually appear
<?php

print "This is dynamic text, should appear, but might disappear";

?>
