Php/as

I have problem with php -> actionscript comunication

in PHP i have:

echo “&fil=Home&”;

flash receive:

Home

and this is ok, but i need variable
in PHP i have:

$ttx=“Home”;
echo “&fil=$ttx&”;

flash receive:

$ttx

I tried plenty of combinations like
echo “&fil=$ttx&”; receiving $ttx
echo “&fil=”.$ttx."&"; “.$ttx.”
echo “&fil=”.$ttx."&"; “.$ttx.”

In one word, i need send variable from PHP to variable in AS

loadVariables(“vars.php”, “_root”, “POST”);
and PHP 5.2.4
