Multidimensional Arrays

[Anon]

I am trying to figure out how to work with a
Multidimensional Array.

for ($g = 0; $g < 10; $g++) {
for ($i = 0; $i < 5; $i++) {
$ucourses[$g][$i] = 7;
}
}

$total = count($ucourses);

echo"$total";

Count returns 12, how do I figure out the total for each part of the array?

Thanks,
Chris

Try:

$sub=count($ucourses[0]);

for($i = 0; $i < count($ucourses); ++$i) {
$count += count($ucourses[$i]);
}

will give you the total number of elements for the second dimension
