<h2>PHP FTP Introduction</h2>
<p>The FTP functions give client access to file servers through the File
Transfer Protocol (FTP).</p>
<p>The FTP functions are used to open, login and close connections, as well as
upload, download, rename, delete, and get information on files from file
servers. Not all of the FTP functions will work with every server or return the
same results. The FTP functions became available with PHP 3.</p>
<p>These functions are meant for detailed access to an FTP server. 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.</p>
<hr />
<h2>Installation</h2>
<p>The windows version of PHP has built-in support for the FTP extension.
So, the FTP functions will work automatically. </p>
<p>However, if you are running the Linux version of PHP, you will have to compile PHP with <i>--enable-ftp </i>
(PHP 4+) or <i>--with-ftp</i> (PHP 3) to get the FTP functions to work.</p>
