invisible enters output=" %0D%0A%" while reading data from php

Hello, i made a php file and returns this output: hello=ok in the internet explorer.

But in flash it outputs hello=ok%0D%0A%

If you look in the source of the internet browser you can see that there are invisible enters after the output text.
It seems flash converts this into code? But i can't seem to find any enters in my php file.

Is there a way to get rid of this %0D%0A% code?

The way i traced the output is:

function dataOnLoad(evt:Event){
trace(evt.target.data);
if(evt.target.data.hello=="ok") {
gotoAndStop(2)
} else message_txt.text = Error??"
}
