In what situations would it be necessary to consider bypassing server restrictions on PHP functions like copy() for specific tasks?

When dealing with server restrictions on PHP functions like copy(), it may be necessary to bypass these restrictions for specific tasks such as moving files between directories or backing up data. This can be achieved by using alternative methods such as FTP or SSH to perform the file operations instead of relying on the restricted PHP functions.

// Example of bypassing server restrictions using FTP to copy a file
$ftp_server = "ftp.example.com";
$ftp_user = "username";
$ftp_pass = "password";

$local_file = "local_file.txt";
$remote_file = "remote_file.txt";

// Connect to FTP server
$ftp_conn = ftp_connect($ftp_server);
ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Copy file from local to remote
ftp_put($ftp_conn, $remote_file, $local_file, FTP_BINARY);

// Close FTP connection
ftp_close($ftp_conn);
