Detect and Display Occurrences of Unique Values in an Array

In PHP, working with arrays often involves handling duplicate values. To efficiently manage and analyze data, it's essential to identify and count these duplicate occurrences. Let's explore a detailed solution to this challenge.

Using the array_count_values() function offers a straightforward approach. This function takes an array as input and returns an associative array where the keys represent unique values from the input array, and the values represent the number of occurrences of each key.

To illustrate this solution, consider the following PHP code:

 $count) {
    echo "$fruit ($count)\n";
}

?>

The output of this code will be:

apple (2)
orange (1)
pear (2)
banana (1)
kiwi (3)

As you can see, the array_count_values() function conveniently provides us with the occurrence count for each unique value in the array. This allows for easy analysis and further processing of the data.
