[RESOLVED] Need help with arrays.

Hi,

I need help with arrays.

How do I get the size out of a multidimensional array?

print_r($NAV);

produces

Array ( [1] => Array ( [1] => Nav 1 [2] => Nav 1.1 [3] => Nav 1.2 ) [2] => Array ( [1] => Nav 2 ) [3] => Array ( [1] => Nav 3 [2] => Nav 3.1 ) )

Or maybe cleaner this way:

$NAV[1][1] = "Nav 1";
$NAV[1][2] = "Nav 1.1";
$NAV[1][3] = "Nav 1.2";
$NAV[2][1] = "Nav 2";
$NAV[1][2] = "Nav 2.1";
$NAV[3][1] = "Nav 3";
$NAV[3][2] = "Nav 3.1";
$NAV[3][3] = "Nav 3.2";
$NAV[3][4] = "Nav 3.3";

In the above array I need to first find out the depth of the main array, i.e the number 3. I can then use the count function on each sub array.

You can use count for all of it, like:

echo count($NAV)."\n<br>";
for ($i=0;$i<=count($NAV);$i++)
{
echo count($NAV[$i])."\n<br>";
}

But of course ;-)

Thanx for the help, I thought I already had tested it but...
