Multi-Dimensional Arrays In PHP ... ???

[David T. Ashley]

Hi,

Aside from the obvious recursive syntax for initialization,

$x = array( ... array( ...)),

what is the best way to deal with multi-dimensional arrays in PHP?

It seems there is no syntax like $x[i][j][k]???

Thanks, Dave.

array_fill() is a good one for some uses, range() fo others.

Euhm, treat them as arrays? What do you want to do with them

There is, almost exactly like it. Remember to quote the kaynames though.

What exactly are you trying to do?

The following is perfectly legal syntax:

<?php

$x[0][1][17] = "Something" ;
$x[0][34][11] = "Something else";

?>

That question is too general to give a sensible answer.
It depends on what you need to accomplish.
eg: You can use the hash indexing, or the normal (integer) indexing.
Why should 1 be better? Depends on your situation.
If you are using a database an associative indexing could make sense for
rows. In other situations the integer indexing makes more sense.

Yes there is.

Dave, read this:

http://nl2.php.net/manual/en/ref.array.php

It will clear up a lot of questions.
And one tip: In my experience: Instead of thinking of multidimensiona l
arrays, it is often simpler and clearer to think of arrays that contain
arrays.

Of course there is.


<?
$monkey["foo"]["bar"]["oof"]["rab"] = "foobar";
print_r($monkey );
?>

Output:
Array
(
[foo] =Array
(
[bar] =Array
(
[oof] =Array
(
[rab] =foobar
)

)

)

)

OK, all questions answered, thanks. In the online documentation, it seemed
to suggest that only way to generate a multi-dimensional array was something
like:

$sub1 = array("apples", "oranges", "bananas", 2*82, 3.1415);
$sub2 = array(24, 57, 91);

$array[0] = $sub1;
$array[1] = $sub2;

This will work, but is awkward.

So, if then

echo $array[0][1];

will give "oranges", then I'm happy.

The syntax is there in the language. Thanks.
