What is the significance of using fgetcsv() function in PHP when reading CSV files for database insertion?

When reading CSV files for database insertion in PHP, using the fgetcsv() function is significant because it allows you to read the file line by line and parse each line into an array of values. This function handles special cases like fields containing commas or double quotes, making it a reliable choice for parsing CSV files. By using fgetcsv(), you can easily extract the data from the CSV file and insert it into your database without worrying about data integrity issues.

$csvFile = 'data.csv';
$handle = fopen($csvFile, 'r');

if ($handle !== false) {
    while (($data = fgetcsv($handle)) !== false) {
        // Insert $data into the database
    }
    
    fclose($handle);
} else {
    echo "Error opening file.";
}
