Step 1: Download and install the ActiveSocket Toolkit

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 ofcourse 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 ActiveSocket object

If you wat to use ActiveSocket 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 ActiveSocket FTP object
$activeFtp = new com("ActiveXperts.FtpServer");

?>

Step 4: Proces the information

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 ActiveSocket FTP object
$activeFtp = new com("ActiveXperts.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>";

?>
