Are there any PHP functions or libraries that can simplify the process of identifying missing numbers in a sequence?

Identifying missing numbers in a sequence involves iterating through the sequence and checking for gaps between consecutive numbers. One way to simplify this process is by using PHP functions like `range()` to generate the complete sequence and then compare it with the given sequence to find the missing numbers.

function findMissingNumbers($sequence) {
    $completeSequence = range(min($sequence), max($sequence));
    $missingNumbers = array_diff($completeSequence, $sequence);
    
    return $missingNumbers;
}

$sequence = [1, 2, 4, 6, 8];
$missingNumbers = findMissingNumbers($sequence);

print_r($missingNumbers);
