PHP - Not Able To Write Code For Traversing Multidimentional Array

Hello every body i have a array like this

Array
(
    [19/5/14] => Array
        (
            [94-DE-80-28-CF-BC] => Array
                (
                    [7] => Array
                        (
                            [qax] => 1
                        )

                )
          }
}

I want to add new array under the [94-DE-80-28-CF-BC] => Array..   I am doing code but what it does it overrides the full array inside that array and create a new one...   The code i've used is

                   |
array_push( $vis[$date][$macp], array(
				"$id"=>array(
				    "$country"=>1
				)
			));

I've got a few arrays as follows:

Code: [Select]
$array1 = ('A', 54, 'a', 2);
$array2 = (, 67, 'b',);
$array3 = ('R', 54,,);
$array4 = (, 36, 'b');
$array5 = (, 36, 'a',);
$array6 = ('FX', 119, 's', 4);
$array7 = ('R', 3, 'c',);

$superarray = array($array1, $array2, $array3, $array4, $array5, $array6, $array7);
Now, I've got a piece of code that sorts $superarray by index[1] of the sub-arrays.  The code looks like this:

Code: [Select]
function sortmulti ($array, $index, $order, $natsort=FALSE, $case_sensitive=FALSE)
               {
              if(is_array($array) && count($array)>0)
                   {
                  foreach(array_keys($array) as $key)
                     $temp[$key]=$array[$key][$index];
                  if(!$natsort)
                       {
                      if ($order=='asc')
                          asort($temp);
                      else   
                          arsort($temp);
                     }   
                  else
                     {
                      if ($case_sensitive===true)
                          natsort($temp);
                      else
                          natcasesort($temp);
                     if($order!='asc')
                         $temp=array_reverse($temp,TRUE);
                     }
                  foreach(array_keys($temp) as $key)
                      if (is_numeric($key))
                          $sorted[]=$array[$key];
                      else   
                          $sorted[$key]=$array[$key];
                  return $sorted;
                 }
             return $sorted;
            }

$sortedarray = sortmulti($superarray, 1, ASC, $natsort=FALSE, $case_sensitive=FALSE)

The output is this:

R3c
36b
36a
A54a2
R54
67b
FX119s4

This is great because it goes 3 -> 36 -> 36 -> 54 -> 54 -> 67 -> 119.

However, the problem, if you look, is this part:

36b
36a

Its sorted everything according to index[1] of the sub-arrays, but now I would like to sort by index[2], then index[3] as well.  I'd like the output to look like this:

R3c
36a
36b
A54a2
R54
67b
FX119s4

Any ideas?  Because this is way over my head ...

Hello everybody,

i am working on n level category tree structure, for your information the category tree structure image is attached with this post.

Let's consider, each of the category have hundreds( n level ) of category in each, i want to traverse each category without using recursive functions, reason being recursive functions are very slow,  is there any way to do this??

Thanks,
phpeid

How do I echo the array below in a for each loop?  I'm trying to output this data in a table.

Good evening all,

I am trying to expand my experience with PHP by doing a small project for a personal website. I am working from scratch using notepad and so far have been having great sucess. My experience with C# is helping greatly but sadly ive hit a snag and can't seem to free myself. I have an array that is populated with items, and the prices for those items if you are buying/selling them. What I will have is a form with a drop list that is populated by this array list (already working) and a text entry that you can enter a numerical quantity value, then another drop list that will have buy / sell as an option. What the page will do is take the values from the form and calculate the "total" from the supplied values. Sadly some reason I cant set a $Variable to the value of the array values. I can echo them and get the correct value, but can't set the Variable to the arrays value!

Code: [Select]
<?php
$ResBuySell = array(
"Iron ingot"  => array("Buy" => 6, "Sell" => 7),
"Shadow iron ingot"  => array("Buy" => 14, "Sell" => 16),
"Dull copper ingot"  => array("Buy" => 14, "Sell" => 16),
"Copper ingot"  => array("Buy" => 6, "Sell" => 7),
"Bronze ingot"  => array("Buy" => 6, "Sell" => 7),
"Gold ingot"  => array("Buy" => 6, "Sell" => 7),
"Agapite ingot"  => array("Buy" => 6, "Sell" => 7),
"Verite ingot"  => array("Buy" => 6, "Sell" => 7),
"Valorite ingot"  => array("Buy" => 6, "Sell" => 7),
"Feathers"  => array("Buy" => 6, "Sell" => 7),
"Arrows"  => array("Buy" => 6, "Sell" => 7),
"Bolts"  => array("Buy" => 6, "Sell" => 7),
"Boards"  => array("Buy" => 4, "Sell" => 6),
"Spined leather"  => array("Buy" => 16, "Sell" => 18),
"Horned leather"  => array("Buy" => 6, "Sell" => 7),
"Barbed leather"  => array("Buy" => 6, "Sell" => 7),
"Cloth"  => array("Buy" => 6, "Sell" => 7),
"Ribs"  => array("Buy" => 6, "Sell" => 7),
"Fish steaks"  => array("Buy" => 6, "Sell" => 7),
"Orange petals"  => array("Buy" => 6, "Sell" => 7),
"Red leaves"  => array("Buy" => 6, "Sell" => 7),
"Green thorns"  => array("Buy" => 6, "Sell" => 7)
);

function GetPrice($ResType = "Iron ingot", $TranType = "Buy")
{
return $ResBuySell[$ResType][$ResType];
}

function GetQuantity()
{
return 5;
}

function GetTotal()
{
$ResPrice = GetPrice();
$ResQuanity = GetQuantity();
$ResTotal = $ResPrice * $ResQuanity;
return $ResTotal;
}

echo GetTotal();
?>

The problem resides he

Code: [Select]
function GetPrice($ResType = "Iron ingot", $TranType = "Buy")
{
return $ResBuySell[$ResType][$ResType];
}

Some reason when I echo this:

Code: [Select]
$ResType = "Iron ingot";
$TranType = "Buy";
echo $ResBuySell[$ResType][$ResType];

it will return;

The proper value, but when I put it into a function and try to retrieve this info via the function it returns zero. I am a beginner with php and just trying to learn by trial and error, but after failing at this for 5 days I figured it was time to call in help from the big guns! Thanks in advance to anyone who can offer my any assistance with this problem!
