muchas gracias Super Lopez! :)
I understand now how this works..
echo "$x<br>";
since you don't escape '$' php knows it's a variable (how does it know
when var name ends though.. since here there's no space between end of
var name and the rest..) will certainly look at urls you suggest..
again muchas gracias....
