Array help

[jrobles]

Im trying to put some information into an array but need some assistance. If i want to put the following info into the array how would I go about it?

 

ProductID

Qty

PricePerUnit

 

The array can contain one product or multiple. Each product will have the three fields i.e.

 

ProductID = 1

Qty = 2

PricePerUnit = $4.00

 

ProductID = 2

Qty = 4

PricePerUnit = $2.76

 

ProductID = 3

Qty = 26

PricePerUnit = $4.34

 

etc...

That really depends on how the data is currently stored and what you want to do with the data, looks like an object would come in handy in this situation to me. Again, depends what you want to do with the data. Do you have any code you can show??

You'll need a multidimensional array. One for each item, contained within one for all items.

 

$items = array();
$items[] = array(
  'ProductID' => 1,
  'Qty' => 2,
  'PricePerUnit' => 4.00
);

$items[] = array(
  'ProductID' => 2,
  'Qty' => 4,
  'PricePerUnit' => 2.76
);

$items[] = array(
  'ProductID' => 3,
  'Qty' => 26,
  'PricePerUnit' => 4.34
);

a quick method (I'm sure there's a better way) is something like this:

<?php
$data = "ProductID = 1
Qty = 2
PricePerUnit = $4.00
ProductID = 2
Qty = 4
PricePerUnit = $2.76
ProductID = 3
Qty = 26
PricePerUnit = $4.34";
$data_array = explode("\n", $data);
$count = 0;
$new_array = array();
foreach ($data_array as $val){
$tmp_array = explode(" = ", $val);
if ($tmp_array[0] == "ProductID"){
	$count++;
}
$new_array[$count][$tmp_array[0]] = $tmp_array[1];
}
print_r($new_array);

If you want a full explanation/help understanding any/all parts of this, just ask.

I eventually will be putting the array in a cookie where I can grab it from another page and insert the  values into a mysql table as part of an "order detail" table. Jonsjava's code looks like what I need , how can I have to data in the $data var regardless of how many products I have. Jonsjava can you help me understand your code, i'm fairly new at PHP

 

thanks a million!

basically, it takes a dump of data, that is formatted exactly like your input:

ProductID = 1

Qty = 2

PricePerUnit = $4.00

 

ProductID = 2

Qty = 4

PricePerUnit = $2.76

 

ProductID = 3

Qty = 26

PricePerUnit = $4.34

and turns it into an array, based upon new lines. it then parses through each new array value, and splits up the value into a new array. It then checks the first bit to see if it's the first item in a new array. if it is, it auto-increments it to the next number. So, if you were working on array 0, and it sees "ProductID" it will begin array 1 and so on.

sweet, I'll give that a shot and see what happens

 

thanks a million!
