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.
建立這個延伸不需要任何外部程式庫。
In order to use FTP functions with your PHP configuration, you should add the --enable-ftp option when installing PHP 4 or greater or --with-ftp when using PHP 3.
Windows 版本的 PHP 已內建此延伸的支援﹐所以你毋須再載入附加的延伸來使用這些功能。
php.ini中沒有定義此延伸的組態指令。
This extension uses one resource type, which is the link identifier of the FTP connection, returned by ftp_connect() or ftp_ssl_connect().
以下的常數由此延伸定義,只在這個延伸被編譯成PHP或實行時期被動態載入時有效。

The following constants were introduced in PHP 4.3.0.
See ftp_set_option() for information.

Example#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);
?>
