Re: [PHP] Populate var with function output string?

[Leif K-Brooks]

Try adding each output string to a variable, then returning it, like:

function return_string(count) {
   $return = '';
   for ($x = 0; $x < $count; $x++) {
        $return.= "<option value=$x> Row $x</option>";

   }
   return $return;
}

If you can't do that for some reason, try using output buffering.

Hey all.

Is it possible to populate a var with an output string generated by a
function? So:
*******************************
function write_string(count) {
   for ($x = 0; $x < $count; $x++) {

        echo "<option value=$x> Row $x</option>";

   }

}

$my_string = write_string(5);

echo $my_string;
*******************************
I need $count option elements stored in $my_string. How to make this happen.

Thanks for any ideas,
