function not returning?

[babygodzilla]

so i have this code

function checkDay($day, $earliestHold)
{
	$dayArraySize = $dayLength * 6;

$s = sizeof($day);

for($x = 0; $x < sizeof($day); $x++)
{
	//echo "$earliestHold -- {$day[$x]['timeStart']} -- {$day[$x]['timeEnd']}<br/>";
	$arrayStart = calcTime($day[$x]['timeStart'], $earliestHold*100)/10;
	$arrayEnd = $arrayStart + calcTime($day[$x]['timeEnd'], $day[$x]['timeStart'])/10;

	//echo"$arrayStart, $arrayEnd<br/>";

	for($y = $arrayStart; $y <= $arrayEnd; $y++)
	{
		$dayArray[$y] = $day[$x];
		$dayArray[$y]['status'] = 'class';
		$dayArray[$y]['arrayStart'] = $arrayStart;
		$dayArray[$y]['arrayEnd'] = $arrayEnd;
		$dayArray[$y]['span'] = $arrayStart - $arrayEnd;
	}
}

echo "{$dayArray[1]['timeStart']}<br/>";

return $dayArray;
}

function buildTable ($earliest, $latest, $m, $t, $w, $r, $f, $s)
{
	$earliestHold = substr($earliest, 0, 2);
	//echo "$earliestHold<br/>";
	$latestHold = substr($latest, 0, 2);

$dayLength = $latestHold - $earliestHold;
$dayLengthPx = $dayLength*60 + 20;

$dayArray[0] = checkDay($m, $earliestHold);
$dayArray[1] = checkDay($t, $earliestHold);
$dayArray[2] = checkDay($w, $earliestHold);
$dayArray[3] = checkDay($r, $earliestHold);
$dayArray[4] = checkDay($f, $earliestHold);
$dayArray[5] = checkDay($s, $earliestHold);

echo "{$dayArray[1][1]['timeStart']}<br/>";


.....
}

so i want checkDay to return stuff into $dayArray. when i process and print stuff out in checkDay(), it all comes out fine. but $dayArray in buildTable() comes up empty, nothing in it. what's wrong?

Does the <br/> from buildTable() output?

[tbach2]

<?php
$test = checkday(put_in_valid_variables);
print_r($test);

?>

does checkday output the array as expected?

function buildTable ($earliest, $latest, $m, $t, $w, $r, $f, $s)
{

...

$test = checkDay($m, $earliestHold);
print_r($test);

...

is it working inside the function?

Looks like you either need to pass in, or declare as a global your $dayLength variable.

Your checkDay function doesn't have a value for it, so $dayArraySize is probably being set to zero.

hmmmm thats a good point. i musta forgot to pass it in. im gonna try that.

edit: actually, never mind. i dont even know why i have $dayArraySize. its not being used anywhere.
