What are some best practices for determining the length of a fgetcsv array in PHP?

When working with fgetcsv in PHP, it can be useful to determine the length of the array returned by the function. One way to do this is by using the count() function on the array. This will give you the number of elements in the array and help you handle the data appropriately.

$row = fgetcsv($file_handle);
$row_length = count($row);

// Use $row_length to determine the number of elements in the array and process the data accordingly
