Remote files can also be moved, renamed, and deleted. The FTP class also includes a "mirroring" function that permits an entire local directory to be recreated remotely via FTP.</p> <p class="important"><strong>Note:</strong> SFTP and SSL FTP protocols are not supported, only standard FTP.</p> <h2>Initializing the Class</h2> <p>Like most other classes in CodeIgniter, the FTP class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p> <code>$this->load->library('ftp');</code> <p>Once loaded, the FTP object will be available using: <dfn>$this->ftp</dfn></p> <h2>Usage Examples</h2> <p>In this example a connection is opened to the FTP server, and a local file is read and uploaded in ASCII mode. The file permissions are set to 755. Note: Setting permissions requires PHP 5.</p> <code> $this->load->library('ftp');<br /> <br /> $config['hostname'] = 'ftp.example.com';<br /> $config['username'] = 'your-username';<br /> $config['password'] = 'your-password';<br /> $config['debug'] = TRUE;<br /> <br /> $this->ftp->connect($config);<br /> <br /> $this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);<br /> <br /> $this->ftp->close(); </code> <p>In this example a list of files is retrieved from the server.</p> <code> $this->load->library('ftp');<br /> <br /> $config['hostname'] = 'ftp.example.com';<br /> $config['username'] = 'your-username';<br /> $config['password'] = 'your-password';<br /> $config['debug'] = TRUE;<br /> <br /> $this->ftp->connect($config);<br /> <br /> $list = $this->ftp->list_files('/public_html/');<br /> <br /> print_r($list);<br /> <br /> $this->ftp->close(); </code> <p>In this example a local directory is mirrored on the server.</p> <code> $this->load->library('ftp');<br /> <br /> $config['hostname'] = 'ftp.example.com';<br /> $config['username'] = 'your-username';<br /> $config['password'] = 'your-password';<br /> $config['debug'] = TRUE;<br /> <br /> $this->ftp->connect($config);<br /> <br /> $this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');<br /> <br /> $this->ftp->close(); </code> <h1>Function Reference</h1> <h2>$this->ftp->connect()</h2> <p>Connects and logs into to the FTP server. Connection preferences are set by passing an array to the function, or you can store them in a config file.</p> <p>Here is an example showing how you set preferences manually:</p> <code> $this->load->library('ftp');<br /> <br /> $config['hostname'] = 'ftp.example.com';<br /> $config['username'] = 'your-username';<br /> $config['password'] = 'your-password';<br /> $config['port'] = 21;<br /> $config['passive'] = FALSE;<br /> $config['debug'] = TRUE;<br /> <br /> $this->ftp->connect($config);<br /> </code> <h3>Setting FTP Preferences in a Config File</h3> <p>If you prefer you can store your FTP preferences in a config file. Simply create a new file called the <var>ftp.php</var>, add the <var>$config</var> array in that file. Then save the file at <var>config/ftp.php</var> and it will be used automatically.</p> <h3>Available connection options:</h3> <ul> <li><strong>hostname</strong> - the FTP hostname. Usually something like: <dfn>ftp.example.com</dfn></li> <li><strong>username</strong> - the FTP username.</li> <li><strong>password</strong> - the FTP password.</li> <li><strong>port</strong> - The port number. Set to <dfn>21</dfn> by default.</li> <li><strong>debug</strong> - <kbd>TRUE/FALSE</kbd> (boolean). Whether to enable debugging to display error messages.</li> <li><strong>passive</strong> - <kbd>TRUE/FALSE</kbd> (boolean). Whether to use passive mode. Passive is set automatically by default.</li> </ul> <h2>$this->ftp->upload()</h2> <p>Uploads a file to your server. You must supply the local path and the remote path, and you can optionally set the mode and permissions. Example:</p> <code>$this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);</code> <p><strong>Mode options are:</strong> <kbd>ascii</kbd>, <kbd>binary</kbd>, and <kbd>auto</kbd> (the default). If <kbd>auto</kbd> is used it will base the mode on the file extension of the source file.</p> <p>Permissions are available if you are running PHP 5 and can be passed as an <kbd>octal</kbd> value in the fourth parameter.</p> <h2>$this->ftp->rename()</h2> <p>Permits you to rename a file. Supply the source file name/path and the new file name/path.</p> <code> // Renames green.html to blue.html<br /> $this->ftp->rename('/public_html/foo/green.html', '/public_html/foo/blue.html'); </code> <h2>$this->ftp->move()</h2> <p>Lets you move a file. Supply the source and destination paths:</p> <code> // Moves blog.html from "joe" to "fred"<br /> $this->ftp->move('/public_html/joe/blog.html', '/public_html/fred/blog.html'); </code> <p>Note: if the destination file name is different the file will be renamed.</p> <h2>$this->ftp->delete_file()</h2> <p>Lets you delete a file. Supply the source path with the file name.</p> <code> $this->ftp->delete_file('/public_html/joe/blog.html'); </code> <h2>$this->ftp->delete_dir()</h2> <p>Lets you delete a directory and everything it contains. Supply the source path to the directory with a trailing slash.</p> <p class="important"><strong>Important</strong> Be VERY careful with this function. It will recursively delete <b>everything</b> within the supplied path, including sub-folders and all files. Make absolutely sure your path is correct. Try using the <kbd>list_files()</kbd> function first to verify that your path is correct.</p> <code> $this->ftp->delete_dir('/public_html/path/to/folder/'); </code> <h2>$this->ftp->list_files()</h2> <p>Permits you to retrieve a list of files on your server returned as an <dfn>array</dfn>. You must supply the path to the desired directory.</p> <code> $list = $this->ftp->list_files('/public_html/');<br /> <br /> print_r($list); </code> <h2>$this->ftp->mirror()</h2> <p>Recursively reads a local folder and everything it contains (including sub-folders) and creates a mirror via FTP based on it. Whatever the directory structure of the original file path will be recreated on the server. You must supply a source path and a destination path:</p> <code> $this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/'); </code> <h2>$this->ftp->mkdir()</h2> <p>Lets you create a directory on your server. Supply the path ending in the folder name you wish to create, with a trailing slash. Permissions can be set by passed an <kbd>octal</kbd> value in the second parameter (if you are running PHP 5).</p> <code> // Creates a folder named "bar"<br /> $this->ftp->mkdir('/public_html/foo/bar/', DIR_WRITE_MODE); </code> <h2>$this->ftp->chmod()</h2> <p>Permits you to set file permissions. Supply the path to the file or folder you wish to alter permissions on:</p> <code> // Chmod "bar" to 777<br /> $this->ftp->chmod('/public_html/foo/bar/', DIR_WRITE_MODE); </code> <h2>$this->ftp->close();</h2> <p>Closes the connection to your server. It's recommended that you use this when you are finished uploading.</p> </div> <!-- END CONTENT --> <div id="footer"> <p> Previous Topic: <a href="form_validation.html">Form Validation Class</a> · <a href="#top">Top of Page</a> · <a href="../index.html">User Guide Home</a> · Next Topic: <a href="table.html">HTML Table Class</a> </p> <p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006-2009 · <a href="http://ellislab.com/">Ellislab, Inc.</a></p> </div> </body> </html>
