ftp:// -- ftps:// — Accessing FTP(s) URLs
Allows read access to existing files and creation of new files
via FTP. If the server does not support passive mode ftp, the
connection will fail.
You can open files for either reading or writing, but not both
simultaneously. If the remote file already exists on the ftp
server and you attempt to open it for writing but have not specified
the context option overwrite, the connection
will fail. If you need to overwrite existing files over ftp,
specify the overwrite option in the context
and open the file for writing. Alternatively, you can
use the FTP extension.
If you have set the from directive
in php.ini, then this value will be sent as the anonymous FTP
FTPS is only supported when the openssl
extension is enabled.
If the server does not support SSL, then the connection falls back
to regular unencrypted ftp.
As of PHP 5.0.0 files may be appended via the
ftp:// URL wrapper. In prior versions, attempting
to append to a file via ftp:// will result in failure.
