Hi everybody,

I generally find any assistance that I need on various sites, but this one has me stumped. I'm not overly advanced with my use of arrays, so I'd like some help here if anyone knows what I am looking for.

I have a form that I would like to submit to a MySQL database. In that form, there is the ability to add up to 3 harddrives:
Code: [Select]
Brand: <input type="text" name="hdds[0][hddbrand]" id="hddbrand"><br/>
Model and/or size,type: <input type="text" name="hdds[0][hddtype]" id="hddtype"><br/>
SN: <input type="text" name="hdds[0][hddsn]" id="hddsn"><br/>
Notes: <input type="text" name="hdds[0][hddnotes]" id="hddnotes" size="50">
Obviously the next harddrive would be hdds[1][hddbrand], etc.

I am having an awful time looping through this to get more than 1 harddrive's information, however. I've tried foreach embedded in foreach and been messing around with this for a good 3-4 hours now and I feel like I am just missing something.

I've got this right now to debug:
Code: [Select]
foreach($_POST['hdds'] as $key => $a) {
$hddbrand = $a['hddbrand'];
}
my print_r($a) comes up with the following:
Code: [Select]
Array ( [hddbrand] => Toshiba [hddtype] => Shaba 500gb [hddsn] => 5fu8bvw4 [hddnotes] =>none ) 1
Good. That's what I want. But I need some help constructing my array/loop to get the values of more than 1 drive should I have to enter information for more than 1 drive.

I feel like I am close, but I am just not getting what I need. I have not had to work with multidimensional arrays before and they are proving to be more trickier than I expected. Any help would be enormously appreciated!

I am looking at the code below:

Code: [Select]
$array = array(
                array(
                1, 2
          ),
          'a' => array(
                'b' => 1,
                'c'
        )
);       
Is this an example of a multidimensional array? If so how would I access the value of 1 from key b?

Also would the next line ('c') be automatically assigned to the asociative key of c?

I need to extract data from a CSV file and insert it into a MySQL database. I am able to extract the data, however I cannot figure out how to group it.

Sample File:
01   ISBN  Name of Book   Price
02   ISBN  Name of Book   Price

So far I have an array with the entire file (reading file with PHP):

Array ([0] => 01 [1] => 12345678X [2] => Title [3] => 120.00 ...etc.

How can I modify the array to create groups of four for each item? Each item is its own array?

I've been working on some code to:
1. Search a db for rows that have a particular "position" value
2. Search the same db for rows that have a particular "langs" value
3. Compare the two arrays resulting for 1 and 2
4. Create a multidimensional array $langsarray[langs][question id] if 3 is true.
5. For each langs array in $langsarray pick a random, non-duplicate value and add it to $qarray for a maximum of 12 elements (3 for each langs).

What I have works about 95%.

The problem is, in the first langs array, one of the 3 randomly picked values is almost always empty, and its not always the same element. Sometimes its the first, sometimes its the third, sometimes its the second...

I think I've narrowed down the issue to line 44 ($qtemp = ...). If I change the min/max values for the mt_rand function, it behaves slightly differently. Any help is much appreciated! Thanks in advance.

Hi All,

I have a function that creates an array using a few sql quereys.  I then use the array to output to html.  I am wanting to add more data to the array to populate another column in the created table.

I am unsure how to add $miqty to the array and then output it in the Qty On Order column. 

I feel like i need to add the [] to

$menuItemsInCat[$mcatname][$miid] = $miname;

section but i am not sure where in there it should be.

I'm trying to create a multidimensional array of movies organized by genre. This should take the form of an associative array with genres as keys.  Each of the arrays elements should be an array containing movie names.

This is what I have:
<?php
$movies = array(
        array("SF" => "", "Terminator", "Soylent Green", "I Robot", "frankenstein"),
         array("horror" => "exorcist", "IT", "frankenstein"),
         array("comedy" => "holy grail", "blazing saddles", "young frankenstein")
    );
   
//echo $movies[0][0]."<br>";
//echo $movies[1][0]."<br>";
//echo $movies[2][0];

foreach ($movies as $c) {
        while (list($k, $v) = each ($c)) {
echo "$k ... $v <br/>";
        }
}
?>

this is the output:
SF ...
0 ... Terminator
1 ... Soylent Green
2 ... I Robot
3 ... frankenstein
horror ... exorcist
0 ... IT
1 ... frankenstein
comedy ... holy grail
0 ... blazing saddles
1 ... young frankenstein

you'll see Terminator is only listed as element 0 because there's an empty string in front of it. The first item in the array is liated as the value to the key while the second value is listed as element 0.  It doesn't seem right to me.

Hi All

I'm new to php and I have a multidimensional array set up which I need to sort for a results list from an assessment.

The array is $gradout['name']['userid']=score.

I need to sort the array by score in a decending order. 

['name'] is a string and ['userid'] is a numeric.

I've tried looking at the php manual but It's just confusing me.  Can anyone explain to me in laymans terms what I need to do and why.

Hi, I am trying to get a random monster from my multidimensional "monsters" array. I have array monsters, and inside that I have array "ocean" and inside that are "fish", "shark" etc.
like the below, and I am trying to pick out a random monster from the Ocean array. Any help greatly appreciated. thank you. Derek

here is the array

Code: [Select]
$monsters = array
(
'Ocean'=>array
(
'octalisk'=>array
(
'name'=>'octalisk',
'hp'=>100,
'damageLow'=>1,
'damageHigh'=>15,
'exp'=>10,
'ac'=>'HAVE TO LOOK THIS UP',
'monsterInitiativeModifier'=>'HAVE TO LOOK THIS UP'),

'shark',
'eel'
),
'Desert'=>array
(
'sand_snake'
),
'Forest'=>array
(
'frog',
'lizard',
'spider'
)
);

<?php
$_SESSION["cart_item"] = array(
'cart_item' => array(
'id' => $id,
'product_name' => $product_name
));
}
$cart_items = $_SESSION["cart_item"];

foreach ($cart_items as $cart_item) {
echo $cart_item["id"] . $cart_item["product_name"];
}
?>

I have tried several variations of the foreach loop like the one above and I mostly get the error message: Notice: Array to string conversion. When I use:
var_dump($cart_items);

I get the following output:

array(1) { ["cart_item"]=> array(2) { ["id"]=> array(2) { [0]=> string(1) "2" [1]=> string(1) "3" } ["product_name"]=> array(2) { [0]=> string(19) "Adult Female Bike" [1]=> string(18) "Kids Unisex Bike" } } }

Hi All

How do I go about splitting a multidimensional array into seperate smaller ones?

Currently I have $grade[region][userid]=value.

I'd like to split as $region1[userid]=value $region2[userid]=value $region3[userid]=value $region4[userid]=value $region5[userid]=value $region6[userid]=value
Is there an inbuilt function for this?

Ok I have a multidimensional array and what I want to know is how to use it. I need to pick the items from the array but only the items specified or individual keys in the array how would I go about doing that. Here is the array:
<?php
$monstors = array
(
  "Skeleton"=>array
  (
  "mob_name"=>"Skeleton",
  "mob_attack"=>"5",
  "mob_hp"=>"30",
  "mob_level"=>"1"
  ),
  "Skeleton Fighter"=>array
  (
  "mob_name"=>"Skeleton Fighter",
  "mob_attack"=>"10",
  "mob_hp"=>"35",
  "mob_level"=>"2"
  ),
  "Skeleton Warrior"=>array
  (
  "mob_name"=>"Skeleton Warrior",
  "mob_attack"=>"15",
  "mob_hp"=>"40",
  "mob_level"=>"3"
  )
);
?>
How would I like print_r the element in the array called Skeleton Warrior?

Hi, I have an array of type array_name[roll_number][aggregate_marks]. How do I sort such array on 'aggregate_marks'? My attempts on sort, asort haven't worked.
