Array function works on one computer, not another.

This code works on my development setup at home, but not at work. The computers are configured the same as far as I can tell.

Here are my errors:

PHP Notice: Undefined variable: array in C:\WindProject\Webroot\functions.php on line 41
PHP Warning: array_key_exists(): The second argument should be either an array or an object in station_compare.php on line 145
PHP Warning: Invalid argument supplied for foreach() in station_compare.php on line 153

#functions.php lines 37-42
function arraymonthyearday ($result){
	while ($line = mysql_fetch_array($result, MYSQL_NUM)) {
		$array[$line[0].$line[1].$line[2]] = $line[3];
	}#while
	return $array;
}#function

#station_compare.php lines 153-159
foreach($station2 as $k => $v) {#remove key if not present in other station
    if (!array_key_exists($k, $station1)) {
		unset($station2[$k]);}
	else{
	#print "$v <br>\n";
	$y[] = $v;}
}#foreach

I can remove the undefined variable error by putting $array="" before the while loop in functions.php... but I don't need to do this on the other computer, and I have the same error reporting settings in php.ini. Any ideas on how to get this foreach to work?

right. the undefined array error is probably caused by not declaring the array as a global variable - it is not in the scope of the function, so it cannot be seen. try

function_arraymonthyearday_($result){ 
while_($line_=_mysql_fetch_array($result,_MYSQL_NUM))_{

the second error, you haven't put the code in...

the third error is to do with setting $station2 as $k => $v. i think you need this instead

foreach($station2[]_as_$k_=>_$v)

notice the square brackets [], to show you are adding an item to the array (pushing)
