What considerations should be made when handling CSV file uploads in PHP, especially regarding different separators like commas and semicolons?

When handling CSV file uploads in PHP, it's important to consider the possibility of different separators like commas and semicolons. To handle this, you can use the fgetcsv() function in PHP, which allows you to specify the delimiter used in the CSV file. By setting the delimiter parameter accordingly, you can handle CSV files with different separators seamlessly. 

$delimiter = ',';
if ($_FILES['csv_file']['error'] == UPLOAD_ERR_OK) {
    $file = $_FILES['csv_file']['tmp_name'];
    $handle = fopen($file, "r");
    
    while (($data = fgetcsv($handle, 1000, $delimiter)) !== FALSE) {
        // Process each row of the CSV file
    }
    
    fclose($handle);
} else {
    echo "File upload error!";
}
