multidimensional arrays

[Anon]

I'm trying to create a 2 dimensional array out of arrays that are already defined.

Like so:
$multarray =array("director"=>$director,"faculty=>$faculty);

This is what I'm using to print the first element of the $director which is also an array:

print "mult = $multarray[0][0]<br>";

I'm sure I'm going about this the wrong way, but I'm not sure if this is just a syntactical error or an error in the logic. I've read all of the posts about multidimensional arrays and don't see anything helpful. I also checked out the online PHP manual and don't see anything about defining multidimensional arrays.

Any help is appreciated.

If you use an array with string indexes instead of integer indexes, you have to make a call to the desired index by name, not by number. For example, if I declare:

$foo["bar"] = "This is a test.";
echo $foo[0]; // This will not output anything
echo $foo["bar"]; // This will output "This is a test."

So you'd have to use:

echo "mult = " . $multarray["director"][0];

But if director is created the same way as the $multarray thingy, you'd have to call for example:

echo "mult = " . $multarray["director"]["name"];

To work with integer type indexes, you should not declare the array with string indexes, but use this:

$director = array($name, $age);
$faculty = array($location, $size);
$multarray = array($director, $faculty);

Then you could say:

echo $multarray[0][0]; // echo's the desired output

Hope this helps a little.

Thanks so much. I wish I had written all of my previous code using this technique.
