What are the best practices for handling special characters like # and space in filenames when working with FTP URLs in PHP?

Special characters like # and space in filenames can cause issues when working with FTP URLs in PHP. To handle these special characters, it is recommended to urlencode the filenames before using them in FTP URLs. This ensures that the special characters are properly encoded and do not cause any errors during FTP operations. 

// Example of handling special characters in filenames for FTP URLs
$filename = "file#name with space.txt";
$encodedFilename = urlencode($filename);

$ftpUrl = "ftp://username:password@ftp.example.com/" . $encodedFilename;

// Now $ftpUrl will be "ftp://username:password@ftp.example.com/file%23name%20with%20space.txt"
