Accessing FTP(s) URLs

Beschreibung

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 password.

Anmerkungen

Hinweis:
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.

Hinweis: Appending
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.
