My PHP Script

    $file_carrito=file("carrito.dat");

    $x=0;

    for($i=0;$i<sizeof($file_carrito);$i++)
    {
    $array_products_1[]=$file_carrito[$i];

    $x++;
    }



echo (array_count_values($array_products_1));

In this simple file .dat , store all products the user add , and count in each case total of products for each id and case

For example i can have into the file 5 ids for one product and other 4 for other product id , finally , this must count products with te same id stored into de dat file

For example : 5 pencils , 3 chairs , 2 tables , etc .....

The problem it´s no works : echo (array_count_values($array_productos_1)); 



content of carrito.dat :

p1
p1
p1
p3
p3
p3
p2
p2
p2
p1
p1



With this function of array i want get :

Product p1 ---- (5)
Product p2 ----- (3) , etc

Thank´s

You should show what carrito.dat looks like –  Sharlike Dec 12 '12 at 14:11
    
What does it do? "Doesn't work" isn't a problem description. –  deceze Dec 12 '12 at 14:15
    
Use sessions [local or server] better than relying on files. –  moonwave99 Dec 12 '12 at 14:16

The easy way:

$data = file('carrito.dat');

print_r(array_count_values($data));

It will show something like the below:

Array
(
    [p1] => 5
    [p3] => 3
    [p2] => 3
)

$data = file('carrito.dat'); $products = array_count_values($data); foreach ($product as $key => $value) { echo "Product $key ---- $value<br />"; } –  AlecTMH Dec 16 '12 at 18:20

count your values like this

$array = array('x', 'x', 'x', 'x', 'y', 'y');
$counts = array();
foreach($array as $value) {
    $counts[$value] = array_key_exists($value, $counts) ? $counts[$value]+1 : 1;
}

print_r($counts);

in your case. the array fill with

$array = explode("\n", file_get_contents(...));
