Start array key at 1
|
|
|
| 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 $timetable[0].
// W days
for ($wdays=0;$wdays <=4;$wdays++) {
echo "<tr>\n";
$day = array('Mon', 'Tue', 'Wed','Thu','Fri');
echo "\t<td class=\"tbl_day\">".$day[$wdays]."</td>\n";
// Periods
for ($periods=1;$periods <=$num_periods;$periods++) {
$eachperiod = $wdays*$num_periods+$periods;
// Fill the table with periods
$fields = $timetable["$eachperiod"];
Cheers,
Chris

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]);

for($periods = 0; $periods < $num_periods; $periods++) {
$eachperiod = $wdays * $num_periods + $periods + 1;
}
