<p>This class assumes that PHP has been built with support for FTP. Since the script
|
|||
|
|
is straightforward we do not discuss it any more in details other than noting that
|
|||
|
|
we use the default system logger to store information that we have uploaded the file
|
|||
|
|
successfully. This is done via the PHP method <span class="command"><strong>syslog()</strong></span>.</p>
