How can the code snippet provided be optimized to improve performance and accuracy in counting the total number of values in a column with comma-separated values in PHP?

The code snippet provided can be optimized by using the explode() function to split the comma-separated values in each row and then counting the total number of values. This approach will improve performance and accuracy by avoiding unnecessary loops and conditions. 

// Assuming $data is an array containing the column values
$totalValues = 0;
foreach ($data as $row) {
    $values = explode(',', $row);
    $totalValues += count($values);
}

echo "Total number of values in the column: " . $totalValues;
