Are there any built-in PHP functions or methods that can simplify the process of counting occurrences of values in an array?

When counting occurrences of values in an array, you can use the built-in PHP function `array_count_values()`. This function takes an array as input and returns an associative array where the keys are the unique values from the input array and the values are the number of occurrences of each value.

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

// Count occurrences of values in the array
$occurrences = array_count_values($array);

// Output the result
print_r($occurrences);
