How do i count same values in an array and store it to a variable?

Question

$items = explode(',',$product); // values is 4,2,4,2,2,4

$unique_items=array_unique($items); // gives me 4,2

What code should be next to give me 4 = 3 , 2 = 3 and store the number of values to a variable?

Do a loop, for n-times (n being the number of elements in $items), then. extract each character at $i ($i would be the current number of loops, also the offset into the string, that is you do for($i=0; i<count($items); $i++){...}) and match that character to each element inside $unique_items, increase a counter variable each time the character inside $unique_items and $items[$i] match, and that's it! You can figure out the code yourself, since I'm a bit rusty with php commands. — omninonsense

Like:

$occurences = array_count_values($items);
print_r($occurences);

Output:

Array
(
    [4] => 3
    [2] => 3
)

Usage:

echo $occurences[4]; // outputs 3

how to store the value of 3 to a variable? tnx

@yohdaman See the updated code. You have all the information in $occurences. If you want to access them, use: $occurences[4] for example.

tnx to all!! very much appreciated. =)

You're probably looking for array_count_values() function.
