In php, we can also directly operate ftp, and then use php to implement the same file upload and download functions as ftp. Here is a complete example.

1. LycFtpAbstract. class. php FTP base class

The Code is as follows: Copy code
<? Php
/* Author: mongoman (lyc)
/* Email: jar-c@163.com
/* Time: 2011-04-22
*/

Abstract class Lyc_Ftp_Abstract {

Protected $ ftpobj = null;
Protected $ host = '';
Protected $ user = 'anonymous ';
Protected $ pwd = '';
Protected $ mode = FTP_BINARY;
Protected $ port = 21;
Protected $ timeout = 90;

Protected $ pasv = TRUE;

Protected function init (){

}
/**
* Establish an ftp connection
*
*/
Protected function connect (){
$ This-> ftpobj = @ ftp_connect ($ this-> host, $ this-> port, $ this-> timeout );
If (null ==$ this-> ftpobj ){
Require_once 'lyc/Ftp/Exception. class. php ';
Throw new Lyc_Ftp_Exception ("ftp error: Couldn't connect to $ this-> host ");
}
}
/**
* Establish an ssl ftp connection
*
*/
Protected function connectSsl (){
$ Ftpobj = @ ftp_ssl_connect ($ this-> host, $ this-> port, $ this-> timeout );
If (null = $ ftpobj ){
Require_once 'lyc/Ftp/Exception. class. php ';
Throw new Lyc_Ftp_Exception ("ftp error: Couldn't connect to $ this-> host ");
}
}
/**
* Login verification ftp and setup Mode
*
*/
Protected function login (){

If (@ ftp_login ($ this-> ftpobj, $ this-> user, $ this-> pwd )){
Ftp_pasv ($ this-> ftpobj, $ pasv );

} Else {
Require_once 'lyc/Ftp/Exception. class. php ';
Throw new Lyc_Ftp_Exception ("ftp error: Couldn't login to $ this-> host ");
}
}
/**
* Upload a file
*
*/
Public function upload ($ remotefile, $ localfile ){

}
/**
* Download an object
*
*/
Public function download ($ localfile, $ remotefile ){

}
/**
* Close the connection.
*
*/
Public function close (){
If (is_string ($ this-> ftpobj )){
Ftp_close ($ this-> ftpobj );
}
}

}
?>

 
 
Ii. LycFtpFtp. class. php implementation class

The Code is as follows: Copy code
<? Php
/* Author: mongoman (lyc)
/* Email: jar-c@163.com
/* Time: 2011-04-22
/*
*/
Require_once 'lyc/Ftp/Abstract. class. php ';
Class Lyc_Ftp_Ftp extends Lyc_Ftp_Abstract {

Public function _ construct ($ host, $ user, $ pwd, $ mode = FTP_BINARY, $ port = 21, $ timeout = 90, $ pasv = TRUE ){
$ This-> host = $ host;
$ This-> user = $ user;
$ This-> pwd = $ pwd;
$ This-> mode = $ mode;
$ This-> port = $ port;
$ This-> timeout = $ timeout;
$ This-> pasv = $ pasv;
$ This-> init ();

}
Protected function init (){

$ This-> connect ();
$ This-> login ();

}
/**
* Upload a file
*
*/
Public function upload ($ remotefile, $ localfile ){

$ Res = ftp_nb_put ($ this-> ftpobj, $ remotefile, $ localfile, $ this-> mode, ftp_size ($ this-> ftpobj, $ remotefile ));
While ($ res = FTP_MOREDATA ){
$ Res = ftp_nb_continue ($ this-> ftpobj );
}
If ($ res! = FTP_FINISHED ){
Return FALSE;
}
Return TRUE;
}
/**
* Download an object
*
*/
Public function download ($ localfile, $ remotefile ){
Ftp_set_option ($ this-> ftpobj, FTP_AUTOSEEK, FALSE );
$ Res = ftp_nb_get ($ this-> ftpobj, $ localfile, $ remotefile, $ this-> mode, ftp_size ($ this-> ftpobj, $ localfile ));
While ($ res = FTP_MOREDATA ){
$ Res = ftp_nb_continue ($ this-> ftpobj );
}
If ($ res! = FTP_FINISHED ){
Return FALSE;
}
Return TRUE;
}
}
?>

 
Iii. LycException. class. php exception base class

The Code is as follows: Copy code
<? Php
/* Author: mongoman (lyc)
/* Email: jar-c@163.com
/* Time: 2011-04-22
/*

*/
Class Lyc_Exception extends Exception {

}
?>
 


Iv. LycFtpException. class. php FTP exception class

 

The Code is as follows: Copy code
<? Php
/* Author: mongoman (lyc)
/* Email: jar-c@163.com
/* Time: 2011-04-22
*/
Require_once 'lyc/Exception. class. php ';
Class Lyc_Ftp_Exception extends Lyc_Exception {

}
?>
 


V. Test Zone

The Code is as follows: Copy code


<? Php
/**
* Upload a file
*
*/
Public function uploadTest (){
Require_once 'lyc/Ftp. class. php ';
$ Host = 23.64.41.13 '; // host
$ User = 'tguser'; // user Name
$ Pwd = ""; // you can change the default password port to 21.
$ Ftp = new Lyc_Ftp_Ftp ($ host, $ user, $ pwd );
$ Res = $ ftp-> upload('test.rar ', "F: wwwroottestareaLycTesttest.rar ");
If (! $ Res ){
Echo "upload failure ";
}

}

Public function downloadTest (){
Require_once 'lyc/Ftp. class. php ';
$ Host = 33.64.41.135 ';
$ User = 'tguser ';
$ Pwd = "";
$ Ftp = new Lyc_Ftp_Ftp ($ host, $ user, $ pwd );
$ Res = $ ftp-> download ("c: test.rar", "test.rar ");
If (! $ Res ){
Echo "download failure ";
}
