Okay...

I have setup an associative array (thru an HTML checkbox form).
All the keys are text, all the values are 1 or null (checked or not).

I need a way to dump all the KEYS of this array into a single variable.


Example:

$airports = array
(
"LGW" => "",
"LHR" => "1",
"STN" => "",
"YYZ" => "1",
"MIA" => ""
);


How do I defing $good as "LHR YYZ" ?
(used a space as a delimiter, but it can be a comma or /, etc.)


I did a bunch of dogpile searching... still haven't been able to figure
it out. I DID find a function that worked, but it only returned the
FIRST instance of a "1". Then it stopped. I need to traverse ALL of
the array.




Thanks!
Mark :)
