php array_count_values multidimensional

In PHP, the array_count_values() function is used to count the number of occurrences of all values in an array. However, this function only works for single-dimensional arrays and cannot directly count occurrences in multidimensional arrays.

To count the occurrences in a multidimensional array, you need to implement your own custom logic. One way to achieve this is by using nested loops and an associative array to store the counts.

Here’s an example:

<?php
$array = array(
    array("apple", "banana", "apple"),
    array("orange", "apple", "banana"),
    array("apple", "orange", "banana")
);

$result = array();
foreach ($array as $subArray) {
    foreach ($subArray as $value) {
        if (isset($result[$value])) {
            $result[$value]++;
        } else {
            $result[$value] = 1;
        }
    }
}

print_r($result);
?>

In this example, we have a multidimensional array with fruits. We initialize an empty $result array to store the counts. Then, we iterate over each sub-array and within each sub-array, we iterate over each value. We check if the value already exists as a key in $result. If it does, we increment the count by 1. Otherwise, we set the count to 1.

Finally, we use the print_r() function to display the count of occurrences for each value in the multidimensional array.

The output of this code will be:

Array
(
    [apple] => 4
    [banana] => 3
    [orange] => 2
)

In this example, “apple” appears 4 times, “banana” appears 3 times, and “orange” appears 2 times in the given multidimensional array.
