Next we define a commonly used function. The function is contained in a file called “functions.php.” It defines a function called listfiles(). This function takes two arguments: the connection resource and the directory. Please, take a look:

<?php

//list files

function listfiles($con,$directory){

echo '<table>';

echo '<tr>

<td></td>

<td>'.ftp_pwd($con).'</td>

</tr>

<tr>

<td><b>File Name</b></td>

<td><b>Action</b></td>

</tr>';

$a = ftp_nlist($con, $directory);

foreach($a as $value){

if(strpos($value,'.') > 0){

$img='images/subpage.gif';

$open="";

}else{

$img='images/fb.gif';

$open='<a href="'.$_SERVER['PHP_SELF'].'?action=view&dirs='.$value.'"><img src="images/open.png" border="0">Open</a>';

}

echo '<tr class="block">';

if($open==""){

echo '<td><img src="'.$img.'" border="0">'.trim($value).'

</td>

<td><a href="'.$_SERVER['PHP_SELF'].'?action=upload&file='.$value.'"><img src="images/upload.bmp" border="0"></a>|<a href="'.$_SERVER['PHP_SELF'].'?action=download&file='.$value.'"><img src="images/download.png" border="0"></a>|<a href="'.$_SERVER['PHP_SELF'].'?action=delete&file='.$value.'"><img src="images/trash.png" border="0"></a>

</td>';

}else{

echo '<td><img src="'.$img.'" border="0">'.trim($value).'</td><td>

'.$open.'';

echo '</td>';

}

echo '</tr>';

}

// close the connection

//ftp_close($con);

echo '</table>';

}

?>

The function starts by building a dynamic table with the headers File and Action:

echo '<table>';

echo '<tr>

<td></td>

<td>'.ftp_pwd($con).'</td>

</tr>

<tr>

<td><b>File Name</b></td>

<td><b>Action</b></td>

</tr>';

Then it calls the ftp_nlist() function to list the files in the given directory. It then stores the result in a variable called $a:

$a = ftp_nlist($con, $directory);
