right, great question!
that's a classic array usage question. you have to use the numeric
keys that come along for free in every simple array (associative
arrrays are arrays where the keys are 'named') or you can use
external counter variables to keep the multiple arrays in sync on
output if keys are not available.
<tr>
<? foreach {
($fieldnames as $key=>$fieldname);
echo '<td><input name="'.$fieldname.'" size="'.$fieldwidth[$key].'" >';
}
echo '></td>';
?>
</tr>
cheers,
dan
