Is it possible to count occurrences without storing values in PHP?

Yes, it is possible to count occurrences without storing values in PHP by using a loop to iterate through the array and incrementing a counter variable whenever a specific condition is met. This allows us to count occurrences without the need to store the actual values themselves.

// Sample array
$array = [1, 2, 2, 3, 3, 3];

// Initialize counter variable
$occurrences = 0;

// Value to count occurrences of
$valueToCount = 3;

// Loop through the array and count occurrences
foreach ($array as $value) {
    if ($value == $valueToCount) {
        $occurrences++;
    }
}

// Output the number of occurrences
echo "Number of occurrences of $valueToCount: $occurrences";
