php multidimensional arrays

Without knowing the structure of your array I can not give a solution, but I guess you find the answer here:
foreach( $category_subcategory_array as $category =>$subcategorys )
       {
          echo '  <li><b>'.$category."</b>\n";
            foreach ( $subcategorys=>$subcategory )  /*****You missed on => I guess******/
            {
                 echo '</br>-'.$subcategory."\n";
          }
       }

Wish I can help

is your array like this:

$subcategory["sub_cat_1"] = array ("motor","bike","bicycle");
$subcategory["sub_cat_2"] = array ("car","truck","tractor");
$subcategory1["sub_cat_3"] = array (1,2,3);
$subcategory1["sub_cat_4"] = array (3,4,5);
$category = array ("category1"->$subcategory, "category2"=>$subcategory1);

foreach ($category as $cat => $subcategory)
{
        echo "<li><b>$cat</b>\n";
        foreach ($subcategory as $subcat => $subsubcategory)
        {
                echo '</br>-'.$subcat."\n";
                foreach ($subsubcategory as $subsubcat=>$value)
               {
                        echo '</br>--'.$value."\n";
               }
        }
       echo "</li>\n";
}


the output of this should be:
<li>category1
-sub_cat_1
--motor
--bike
--bicycle
-sub_cat_2
--car
--truck
--tractor
</li>
<li>category2
-sub_cat_3
--1
--2
--3
-sub_cat_4
--3
--4
--5
</li>

it is a bit like that,

it is a an array made of 3 dimensions - $array[category][subcategories][sub-subcategories]

so, each category has many subcategories and in turn each subcategory has many sub sub categories.

i'm just wondering if you know how to output the sub sub categories?

also, if a category had no subcategories and hence no sub sub categories how would i leave the subcategories array and sub sub categories array blank?? can this be done??

thanks

yup.
can u post sample data of yours?

Can you do:

echo "<pre>"; print_r($category_subcategory_array); echo "</pre>";

and post the results, this will give a better idea of the exact structure of the array. If this will produce a great big long output (e.g. you have alot of categories and subcategories) then try limited the amount of data put into the array before your do the print_r.

here are the results :

Array
(
    [range] => Array
        (
            [0] => range-debossed.html

            [1] => range-embossed.html

            [2] => range-printed.html

        )

    [cat] => Array
        (
            [0] => cat-cat.html

            [1] => cat-cat2.html

        )

    [cat2] => Array
        (
            [0] => cat2-subcat2.html

            [cat2-subcat2.html
] => Array
                (
                    [0] => cat2-cat2subcat2-subsubcat.html

                )

        )

)

thanks

if your variable is: $array
then your code will be:

foreach ($array as $cat => $subcat_group)
{
     echo "<li><b>$cat</b>\n";      
        foreach ($subcat_group as $subcat=>$subsubcat_group)
       {
             if (is_numeric($subcat)) {
                   echo '</br>-'.$subsubcat_group."\n";
             } else {
                     echo '</br>--'.$subsubcat_group."\n";
             }
      }
      echo "</li>\n";
}

this is based on your data group.

that doesnt seem to access the sub sub category

dont you need another for loop?

if, an array was empty would that cause error? is there any way of allowing an empty array.
so for example some sub categories wont have any sub subcategories and therefore no subsubcategory array.

However, the for loop will still be there to try and access the values

Yup. It caters for that.
Did you try it?

If it fails, can you post about 2 sets of your data?
Your array structure is unique, do you know that? :p

range
-range-debossed.html
-range-embossed.html
-range-printed.html
cat
-cat-cat.html
-cat-cat2.html
cat2
-cat2-subcat2.html
--Array

is the output. I guess its just not accessing the values of the subsubcategories

excellent
thank you very much

Glad I could help.
