Help Compare Numbers In A List!

[Flezria]

Hi guys!

 

I have a list of ID's where i want to count how many of them there is equally to each other.

My list is like this: 174,174,226,227,226,226,226

 

Anyone can tell me how to do this? I've the following code at the moment:

 

 

$cart = $_SESSION['cart'];
$items = explode(",",$cart);
echo $cart;
$i = 0;
$count = count($items);
$antal = array();
while($i < $count) {
{
$i++;
// Some code in here
}
}

 

Thanks a lot for your help!

Try array_count_values.

Ah, forgot to say i've already tried that.. :-(

If you change the definition of your cart to be an array - $_SESSION['cart'][id] = n; // where n is the quantity of that id in the cart, all your code will be greatly simplified.

 

The sample cart you posted would look like -

 

$_SESSION['cart'][174] = 2

$_SESSION['cart'][226] = 4

$_SESSION['cart'][227] = 1

How so?

I don't quite understand what you mean.

I want to save the output in a new array, so i can use it to post later on, would it look like this?

$cart = $_SESSION['cart'];
$cart = array();
$items = explode(",",$cart);
$i = 0;
$count = count($items);
$antal = array();
while($i < $count) {
{
$antal[$i] = array_count_values($cart)
echo $antal[$i]; //Just to check if it works
$i++;
}
}

I tried to put it into array_count_values and it told me it was a string, instead of an array.

Right now i'm trying to compile the numbers into an array, so i can do array_count_values.

I have this right now, but it doesn't seem to quite do the job:

$items = explode(',',$_SESSION['cart']);
$cart = $_SESSION['cart'];
$i = 0;
$count = count($items);
while($i < $count) {
$cart = array($i, "$items[$i]");
$i++;
}
$antal = array();
while($i < $count) {
{
$antal[$i] = array_count_values($cart);
echo $antal[$i];
$i++;
}
}

<?php

$arr = array(174,174,226,227,226,226,226) ;

$count = array_count_values($arr);

echo '<pre>'.print_r($count, 1).'</pre>';
?>

output:

Array
(
   [174] => 2
   [226] => 4
   [227] => 1
)

 

In what way did array_count_values() not tell you what you wanted to know?

The problem is, those id's are something i get from whatever my customer picked as an order, they're not already an array, so i have to "convert" them somehow, in order to use the array_count_values() function, my code is this, but it doesn't seem to work:

 

 

$items = explode(',',$_SESSION['cart']);
$cart = array();
$i = 0;
$count = count($items);
while($i < $count) {
array_push($cart, $items[$i]);
$i++;
}
$antal = array();

$arraycount = array_count_values($cart);

echo '<pre>'.print_r($arraycount, 1).'</pre>';

Do you know what explode does?

[Flezria]

Do you know what explode does?

 

I'm pretty sure it "splits" the lines, where the "," is, so i get raw numbers.

Yes, and it gives you back an array which you could then pass into array_count_values.

 

$values = explode(',', $_SESSION['cart']);
$count = array_count_values($values);
print_r($count);

aaah, thanks a lot! It seems to give the right print, but i doesn't allow me to use like the first number only? fx. I have 100,100,100,101,102 that means i have 3 of the same product, then i want to print the next to the order, so it tells me the customer bought 3 of that product? I tried $count[0], but doesn't seem to do the trick?

Thanks a lot, that fixed my problem!

I can only assume you're not being sarcastic, and say you're welcome :-P
