How can you optimize the process of counting specific entries in a multidimensional array in PHP?

To optimize the process of counting specific entries in a multidimensional array in PHP, you can use a combination of array functions such as array_column() to extract the specific values you want to count and then use array_count_values() to get the count of each unique value. 

// Sample multidimensional array
$array = [
    ['apple', 'banana', 'apple'],
    ['banana', 'orange', 'banana'],
    ['apple', 'orange', 'apple']
];

// Flatten the array and count specific entries
$flatArray = array_column($array, 0); // Assuming we want to count 'apple'
$counts = array_count_values($flatArray);

// Output the counts
echo "Count of 'apple': " . ($counts['apple'] ?? 0);
