PHP FTP Client Sample Source Code

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 the 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 HTML form

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

If you wat to use Network Component Ftp in PHP, you need to create an object. In PHP this means you need to create a new COM. The following code shows how to do this.

<? //create the Network Component FTP object
$activeFtp = new com("AxNetwork.FtpServer");
?>

Appendix: Full source code

Now we need to connect to the server and display the content of the server. In this sample we're working with a form. If the form is submitted, we're passing The following code shows how to do this:

<?

//create the Network Component FTP object
$activeFtp = new com("AxNetwork.FtpServer");

if(isset($_GET['method'])){

  //set the logfile:
  $activeFtp->logfile = $_POST["logfile"];

  //connect the server
  $activeFtp->connect($_POST["server"], $_POST["username"], $_POST["password"]);

  //change directory
  $activeFtp->ChangeDir($_POST["dir"]);
  
  //display the table in witch we are going to present our information
  echo "<table>";
  echo "  <tr>";
  echo "    <td colspan=1 class=header>";
  echo "Size:";
  echo "    </td>";
  echo "    <td class=header>";
  echo "Filename:";
  echo "    </td>";
  echo "  </tr>";

  //get the firstfile (if the first file is fetched, move on to the next untill there is no next file, then an error will occure)  
  $files = $activeFtp->FindFirstFile();

  //get the errors and descriptions
  $error = $activeFtp->Lasterror;
  $description = $activeFtp->GetErrorDescription($activeFtp->Lasterror);
  
  //if the filename was successfully fetched, echo the filename and the filesize
  while($activeFtp->Lasterror == 0){
    echo "  <tr>";
    echo "    <td class=size>";
    //check if the file is a directory    
    if($files->isDirectory == -1){
      //if the file is a directory: echo "Directory"    
      echo "Directory";
    }
    else{
      //if the file isn't a directory, echo the filesize    
      echo $files->size . " Bytes";
    }
    echo "    </td>";
    echo "    <td class=filename>";
    echo $files->name . "<br>";
    echo "    </td>";  
    echo "  </tr>";
    
    //find the next file, and display it again..
    $files = $activeFtp->FindNextFile;    
  }
  
  //close the table tag
  echo "</table>";
  echo "<br>";

//close the if statement
}


//create a table and display the errors that have occured
echo "<table>";
echo "  <tr>";
echo "    <td colspan=1 class=header>";
echo "ErrorNo.:";
echo "    </td>";
echo "    <td class=header>";
echo "Error description:";
echo "    </td>";
echo "  </tr>";
echo "  <tr>";
echo "    <td class=size>";
echo $error;
echo "    </td>";
echo "    <td class=filename>";
echo $description;
echo "    </td>";
echo "  </tr>";
echo "</table>";

?>
