Adding elements to arrays

[rulian]

I have a query, which will return many rows of the following: 'id' 'title' 'catagory' 'subcatagory'.

I need to enter them in an array in the following structure:

$array=array(
$catagory => ( array
$subcatagory => (array
$id => (array
"title" => $title

problem is, i have little experice with arrays, so I dont even know if this structure will work. But I'll be running this array inside a for loop, and each loop will enter new data into the array, but as I have it all it will do (should one day this structure work) is replace array, but I need to keep the existing elements in the array.

Also, will this structure work if I need the title of id 2 on subcat 4 cat 3 by going echo $array[3][4][2]["title"] ???

Yes, you can do this.

Although, it might be less confusing just to assign them using $array[3][4][2]... instead of trying to use array().

$array[3][4][2]["title"] = "test";

then:

echo $array[3][4][2]["title"];

will print "test". If you want to understand this more,

echo $array[3][4][2];

will print "array" (since it is an array type, and php won't directly print this).

$array[3][4][2] = array("title" => "test");

will do the same thing.

Because PHP is an untyped language, arrays in php are VERY powerful. You can assign any type of variable to an item in an array, including another array.
