ftp_site

(PHP 4, PHP 5, PHP 7, PHP 8)

ftp_site — Sends a SITE command to the server

Description

function ftp_site(FTP\Connection $ftp, string $command): bool

ftp_site() sends the given SITE command to the FTP server.

SITE commands are not standardized, and vary from server to server. They are useful for handling such things as file permissions and group membership.

Parameters

ftp

An FTP\Connection instance.

command

The SITE command. Note that this parameter isn't escaped so there may be some issues with filenames containing spaces and other characters.

Return Values

Returns true on success or false on failure.

Changelog

Version Description
8.1.0 The ftp parameter expects an FTP\Connection instance now; previously, a resource was expected.

Examples

Example #1 Sending a SITE command to an ftp server

<?php
// Connect to FTP server
$ftp = ftp_connect('ftp.example.com');
if (!$ftp) die('Unable to connect to ftp.example.com');

// Login as "user" with password "pass"
if (!ftp_login($ftp, 'user', 'pass')) die('Error logging into ftp.example.com');

// Issue: "SITE CHMOD 0600 /home/user/privatefile" command to ftp server
if (ftp_site($ftp, 'CHMOD 0600 /home/user/privatefile')) {
   echo "Command executed successfully.\n";
} else {
   die('Command failed.');
}
?>
