The print lines above are supposed to produce a list of links to files. In the web display I get duplicate sets of links which seems to mean that the loops in the function are running twice, and in one instance three times instead of once.

Look at the variable names you use for iteration. Thanks, Usually, when a variable name like $i is used and then

reset to 0 in the next loop it does not matter. But I solved the problem and posted the solution. I also solved the regex problem. There was an extra \n sneaking into the test pattern so I could not get a match. I am not sure where the extra \n is coming from. It looks like I didn't post the solution after all: Update: I solved the double loops problem with this code change: function display($list, $a, $x)

                {
                 for($i = 0; $i < count($a); $i++)
                    {$j = $i + 1;
                     print "<a href=\"steps.php?list=$list&next=$j&x=$x\">$j</a><br><br>\n";
                    };
                 }

and: if($list || $current) {

    switch($list)
          {
           case 'in':
           display($list, $in, $x);
           break;
           case 'out':
           display($list, $out, $x);
           break;
           case 'save':
           display($list, $save, $x);
           break;
           case 'req':
           display($list, $req, $x);
           break;
          }

} Apparently what was happening was that the code running under 5.1.2 was trying to process all the arrays that had values in spite of the switch statement in the original display() function. If the was an $in array the switch would process that for the $list value being 'in' but since there was also a save value, the switch tried to process it also, even though 'save' wasn't the $list value. I found it would do this for all arrays that had values. So if three had values the loop selected loop would run three times. Could this be a bonafide bug? JK
