Network Component provides an easy-to-use development interface to a variety of IP protocols. By using Network Component, you can very easily create or enhance applications with network features.

Network Component features the following: DNS, FTP, HTTP, HTTPs, ICMP Ping, IP-to-Country, MSN, NTP, RSH, SCP, SFTP, SNMP v1/v2c (Get, GetNext, Set), SNMP Traps, SNMP MIB, SSH, TCP, Telnet, TFTP, UDP, Telnet, Wake-On-LAN and more.

Network Component can be well integrated into any development platform that supports ActiveX objects.

This document describes how the Network Component FtpServer object can be integrated into your projects.

The most important functions of the FtpServer object are:

• Connect - connect to the (remote) FTP server on port 21 or any alternate port;
• Disconnect - to diconnect after a connect call;
• GetCurrentDir - retrieve the current directory;
• ChangeDir - change the current directory;
• CreateDir - create a new directory;
• RenameDir - rename a directory;
• DeleteDir - delete a directory;
• FindFile - find a specific file in the current directory;
• FindFirstFile - iterate over all files in the current directory; find the first file;
• FindNextFile - iterate over all files in the current directory; find the next file;
• RenameFile - rename a file in the current directory;
• DeleteFile - delete a file in the current directory;
• GetFile - get (download) a file, either using binary transfer or ASCII transfer;
• PutFile - put (upload) a file, either using binary transfer or ASCII transfer;

Step 1: Download and install Network Component

Download Network Component from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new Web Site

To connect to an ftp server using PHP we need to collect the login information from the user, then connect to the server and then view the content

First of all we need to collect some information from the user. Like the username, the password and of course the server we are going to connect to. Perhaps you'd like to change the directory or/and create a logfile at logon. You can make the form look like this.

Step 3: Create the Network Component object in PHP

To create the Network Component object in php use the following code:

<? //create the Network Component FTP object
$objHttp = new COM (AxNetwork.Http);
?>

Appendix: Full source code

In this sample we have built a page that is able to display the source code of another page. You're also able to get source codes from secured area's if you fill in the username and the password. The results are displayed in the page. To do this, we're using the following code.

<?
  $url = $_POST['url'];
  if($url != ""){
    //first create the object, AxNetwork.http is a com object
    $objHttp = new COM ("AxNetwork.Http");
    
    //Fill in the username and password
    if($error != 0){
       $errormessage = $objHttp->getErrorDescription($objHttp->lasterror);            
    }
    else{
        $objHttp->WebAccount = $_POST['username'];
        $objHttp->WebPassword = $_POST['password'];
    }
    $error = $objHttp->Lasterror;
    
    //if the username and password are succesfully set, we can connect the server
    if($error != 0){
        $errormessage = $objHttp->getErrorDescription($objHttp->lasterror);            
    }
    else{
        //connect
        $objHttp->Connect($url);
    }
    $error = $objHttp->Lasterror;
    
    if($error != 0){
        $errormessage = $objHttp->getErrorDescription($objHttp->lasterror);            
    }
    else{
        //echo the sourcecode of the page
        //convert < and > of the code using htmlentities()
        echo htmlentities($objHttp->ReadData());
    }
  }       
?>
