Alright, this php is abit more advanced then the rest posted here. I just thought id show you guys some more complicated stuff involving a class.
Alright, so first of all we need to create a class.
Now we need to create some vars and functions in this class.
PHP Code:
class ftp
{
var $_server = NULL;
var $_login = NULL;
function ftp ( $username, $password, $server )
{
$this->_server = @ftp_connect ( $server );
$this->_login = @ftp_login ( $this->_server, $username, $password );
if ( ! $this->_server )
{
die ( "Sorry, unable to connect to the server ( $server )" );
}
if ( ! $this->_login )
{
die ( "Sorry, the login, ( $username ), or password, ( $password ), was incorrect." );
}
else
{
echo " Succesfully connected to ( $server ) on user ( $username ) <br />";
}
}
function flist()
{
$files = ftp_nlist($this->_server, ".");
foreach ($files as $file)
{
echo "<br>$file";
}
}
function close()
{
@ftp_close($this->_server);
}
}
Alright, by looking at that big amount of functions and vars, you are probably pretty confused. Let me break it down abit for you.
The first function i made is used to connect to the FTP server.
This code is simply trying the username and password and telling you if it worked or not.
PHP Code:
function ftp ( $username, $password, $server )
{
$this->_server = @ftp_connect ( $server );
$this->_login = @ftp_login ( $this->_server, $username, $password );
if ( ! $this->_server )
{
die ( "Sorry, unable to connect to the server ( $server )" );
}
if ( ! $this->_login )
{
die ( "Sorry, the login, ( $username ), or password, ( $password ), was incorrect." );
}
else
{
echo " Succesfully connected to ( $server ) on user ( $username ) <br />";
}
}
The second function needed is the function to display the files in the server.
PHP Code:
function flist()
{
$files = ftp_nlist($this->_server, ".");
foreach ($files as $file)
{
echo "<br>$file";
}
}
And the third function is the function used to close the connection.
PHP Code:
function close()
{
@ftp_close($this->_server);
}
And Last, but not least, we need to create the forms.
In this code, we create a form with the textboxes and everything we need, we also have another PHP script at the bottom, this is used if the server the person wants to connect to uses an anonymous account. If the person doesnt enter a username, it is automaticaly set to anonymous.
PHP Code:
<html>
<title>FTP Connect</title>
<body>
<form method="POST" action="<?php echo basename(__FILE__); ?>">
<P CLASS="centeralign"> Ftp Server:<br />
<input type="text" size="20" maxlength="30" name="server">
<br />
Username:<br />
<input type="text" size="20" maxlenghth="20" name="username">
<br />
Password:<br />
<input type="password" size="20" maxlenghth="20" name="password">
<br />
<br />
<input type="submit" value="Connect!">
<br />
<br />
</P>
</form>
<div align="center">
</div>
</body>
</html>
<?php
$serv = $_POST["server"];
$user = $_POST["username"];
$pass = $HTTP_POST_VARS["password"];
if ( empty($user) )
{
$user = 'anonymous'
}
if ( !empty($serv) && !empty($user) )
{
$ftp = new ftp ( "$user", "$pass", "$serv" );
$ftp->flist();
$ftp->close();
}
?>
And here is the complete sourcecode.
Sorry if i didnt explain well enogh this is my first tutorial. Let me know comments or if you want me to change anything
PHP Code:
<?php
class ftp
{
var $_server = NULL;
var $_login = NULL;
function ftp ( $username, $password, $server )
{
$this->_server = @ftp_connect ( $server );
$this->_login = @ftp_login ( $this->_server, $username, $password );
if ( ! $this->_server )
{
die ( "Sorry, unable to connect to the server ( $server )" );
}
if ( ! $this->_login )
{
die ( "Sorry, the login, ( $username ), or password, ( $password ), was incorrect." );
}
else
{
echo " Succesfully connected to ( $server ) on user ( $username ) <br />";
}
}
function flist()
{
$files = ftp_nlist($this->_server, ".");
foreach ($files as $file)
{
echo "<br>$file";
}
}
function close()
{
@ftp_close($this->_server);
}
}
?>
<html>
<title>FTP Connect</title>
<body>
<form method="POST" action="<?php echo basename(__FILE__); ?>">
<P CLASS="centeralign"> Ftp Server:<br />
<input type="text" size="20" maxlength="30" name="server">

<input type="password" size="20" maxlenghth="20" name="password">
<br />
<br />
<input type="submit" value="Connect!">
<br />
<br />
</P>
</form>
<div align="center">
</div>
</body>
</html>
<?php
$serv = $_POST["server"];
$user = $_POST["username"];
$pass = $HTTP_POST_VARS["password"];
if ( empty($user) )
{
$user = 'anonymous'
}
if ( !empty($serv) && !empty($user) )
{
$ftp = new ftp ( "$user", "$pass", "$serv" );
$ftp->flist();
$ftp->close();
}
?>
