1)I have seen a website use this code

> \<embed…\<src=“**myFlash.swf?url=[http://yoursite.com/clip.flv](http://yoursite.com/clip.flv)**”  
> I don’t know how to create and use this kind of variable (?url=) in flash

2)I often send date (such as Score) from Flash to PHP and then insert it to mySql

```php
Ex : _root.loadVariables("mkScore.php?name=" & name & "&score=" & score & "",POST)

```

But i am afraid that someone or “something” by someway may get my secret url “mkScore.php” and changes their score like that :

> mkScore.php?name=kingGame&score=1000000000  
> So i added more variable that names is “passkey” and my url looks like that  
> \_root.loadVariables(“mkScore.php?name=” & name & “&score=” & score & “&passkey=123456tototete”,POST)  
> And then i will check it’s value in PHP when flash send data  
> Is this the best way to secure sending data and deny user changing their score. Are there some ways???
