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.html. 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.
No external libraries are needed to build this extension.
In order to use FTP functions with your PHP configuration, you should
add the --enable-ftp option when
installing PHP 4 or --with-ftp when using
PHP 3.
The windows version of PHP
has built in support for this extension. You do not need to load any additional
extension in order to use these functions.
This extension has no configuration directives defined in php.ini.
This extension uses one resource type, which is the link identifier
of the FTP connection, returned by ftp_connect().
