XXXIV. FTP Functions

Introduktion

The functions in this extension implement client access to file servers speaking the File Transfer Protocol (FTP) as defined in http://www.faqs.org/rfcs/rfc959. This extension is meant for detailed access to an FTP server providing a wide range of control to the executing script. If you only wish to read from or write to a file on an FTP server, consider using the ftp:// wrapper with the filesystem functions which provide a simpler and more intuitive interface.

Exempel

Exempel 1. FTP example
<?php // set up basic connection $conn_id = ftp_connect($ftp_server); // login with username and password $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // check connection if ((!$conn_id) || (!$login_result)) { echo "FTP connection has failed!"; echo "Attempted to connect to $ftp_server for user $ftp_user_name"; exit; } else { echo "Connected to $ftp_server, for user $ftp_user_name"; } // upload the file $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); // check upload status if (!$upload) { echo "FTP upload has failed!"; } else { echo "Uploaded $source_file to $ftp_server as $destination_file"; } // close the FTP stream ftp_close($conn_id); ?>
