generating table in a for loop inside a for loop

[overflo]

I'm trying to generate a table that displays a schedule. It calls two other functions (get_timeslot() & get_timetable()) These are working fine as it is displaying the correct data, just not inside the table. The table displays below it, only empty.
here is the code
function show_timetable() {
$returnStr = "<table width='90%' border='2' cellspacing='3' cellpadding='3'>
<tr>
<td width='24%'>Times</td>\n
<td width='11%'>Mon</td>\n
<td width='11%'>Tue</td>\n
<td width='11%'>Wed</td>\n
<td width='11%'>Thu</td>\n
<td width='11%'>Fri</td>\n
<td width='11%'>Sat</td>\n
</tr>";

for ($timeslot = 1; $timeslot < 10; $timeslot++) {
$returnStr .= '<tr>' . '<td>' . get_timeslot($timeslot) . '</td>';
for ($day = 1; $day < 7 ; $day++) {
$returnStr .= '<td>' . get_timetable($day, $timeslot) . '</td>';
}
$returnStr .= '</tr>' ;
}
$returnStr .= '</table>';
echo $returnStr;
}

Examine the source code of the page this script generates. Is there anything odd about it?

overflo, sleipnir214,

I was just working on this example, I'm thinking that overlfo is "echoing or printing" the output of the functions.

overflo,
You want to use return when you use a function in this context.

<?php
$first_name = array('Matt','Susan','Mary');
$last_name = array('Jones','Smith','Williams');

function showNames($x){
global $first_name, $last_name;
return "{$first_name[$x]} {$last_name[$x]}";
}

$htmlStr = "<table><tr>
<td>Names</td></tr>
<tr>
<td>". showNames(2) ."</td></tr>
</table>";

echo $htmlStr;
?>

Thanks,
