Use Text as Variable?

spishack

Is there a way to use a variable to get another variable?

Basically, i have this:

$feb_days = 28;

and then I have this:

$timeformonth = time();
$monthcode = date("M", $timeformonth);
$monthcodelower = strtolower($monthcode);
$cur_month = $monthcodelower;
$cur_month .= "_num";

Now, $cur_month echoed would output feb_days. Is there a way in PHP to get $cur_month to output 28?

something like this....

eval("echo \$$cur_month");

Oops, nevermind. I used an array. I had already tried and array and it didn't work (hence my original post), but I realized I had made an error.

If anyone is interested in how I did this, just reply.

Hmm... this didn't work for me...

$cur_month ="feb_days";

echo $$cur_month;

Ah ha! I had hoped there was something like this... thanks, it worked much better.
