How can file deletion errors, such as "Cannot delete," be resolved when using FTP functions in PHP scripts on a localhost server?

When encountering file deletion errors like "Cannot delete" when using FTP functions in PHP scripts on a localhost server, it may be due to file permission issues. To resolve this, you can set the proper permissions for the file or directory before attempting to delete it using the PHP `chmod` function.

// Set the proper permissions for the file or directory
chmod($file_path, 0777);

// Attempt to delete the file
if (ftp_delete($ftp_conn, $file_path)) {
    echo "File deleted successfully";
} else {
    echo "Error deleting file";
}
