How can I change the following snippet to have the array key start at
1 and not 0?
$timetable = explode(',', $row['timetable']);
It is taken from the following code...first time around the loop
$timetable["$eachperiod"] = $timetable[1] which puts me out of sync
with the number of fields I am creating ie. I lose $timetable[0].
// Weekdays
for ($weekdays=0;$weekdays <=4;$weekdays++) {
echo "<tr>\n";
$day = array('Mon', 'Tue', 'Wed','Thu','Fri');
echo "\t<td class=\"tbl_day\">".$day[$weekdays]."</td>\n";
// Periods
for ($periods=1;$periods <=$num_periods;$periods++) {
$eachperiod = $weekdays*$num_periods+$periods;
// Fill the table with periods
$fields = $timetable["$eachperiod"];

What is your problem? Except for ancient languages like Fortran, arrays
start at 0. Simply rewrite the loop to be:
for ($periods=0;$periods <$num_periods;$periods++) {

Also you don't need the double quotes around $eachperiod, i.e.
$fields=$timetable[$eachperiod];

You could unshift the array and then delete the new item immediately,
but this ugly and makes no sense, since you can work with your array
without transformation.
array_unshift($periods);
unset($periods[0]);
[...]
// Periods
for ($periods=1;$periods <=$num_periods;$periods++) {
$eachperiod = $weekdays*$num_periods+$periods;
for($periods = 0; $periods < $num_periods; $periods++) {
$eachperiod = $weekdays * $num_periods + $periods + 1;
