O.P.  RE: Something in this PHP code is causing the webserver to be unresponsive
 braces are only needed if there is being more than one line being executed, as a group of code. And yes, it is by design. if I replaced the 'while' with a 'for' only the first occurrence of each icon would be displayed. 
 
so, does anyone have any good suggestions to offer?
