Dynamic function calls within the echo function, possible?

Yo, i run some fairly simplistic sites, and still don't know to much PHP. Anyways i have this function called row color, it works fairly simply. $row1 = "bgcolor='#c0c0c0'"; $row2 = "bgcolor='#808080'"; function row_color(&$row_color=null) {

         static $row_count=0;
         $row_color = ($row_count % 2) ? $GLOBALS['row1'] : $GLOBALS['row2'];
         $row_count++
         return $row_color;

} what i want to do, is somehow dynamicly call that funciton within an echo or print function though. something like $row = "row_color"; echo "$row()<br>$row()<br>$row()"; but i cant seem to find a way to properly do this. That just returns null values, i have been screwing around with it for about a week now, and another two weeks trying to get it working on classes, but i cant figure out if it is even possible to do. The idea bewteen the &$row_color is so that i can optionally use referencing on other places in the scripts i have. -XeRnOuS _________________________________________________________________ Don’t just search.
