How can PHP developers ensure accurate counting of lines and fields when processing CSV files?

When processing CSV files in PHP, developers can ensure accurate counting of lines and fields by using the `fgetcsv()` function to read each line of the CSV file and automatically parse it into an array of fields. By checking the count of fields in each array, developers can accurately count the number of fields in each line. Additionally, developers can keep track of the total number of lines processed to ensure accurate counting. 

$filename = 'data.csv';
if (($handle = fopen($filename, 'r')) !== FALSE) {
    $lineCount = 0;
    while (($data = fgetcsv($handle)) !== FALSE) {
        $fieldCount = count($data);
        // Process data or perform necessary actions
        $lineCount++;
    }
    fclose($handle);
    echo "Total lines processed: $lineCount";
} else {
    echo "Error opening file";
}
