[deleting a file from a list]

hey everyone, its my first topic here, and i'm at a beginner level with php, so excuse my poor level

well, i have a problem trying to add a delete button or link next to each file in query so the user can delete the file. and that's the code i'm using in my page:

<?php
  include ("functions.php");
include ("header.php"); 
// Settings section ------------------------------

$co_filedir = "../conseiller/files/"; 				// The file folder
$columns = 1; 				        // Number of columns of files listed per row
$tablewidth = 800;                              // Table Width
$namecolumn = ($tablewidth / $columns) / 2;     // File Name Column Width
$datecolumn = $namecolumn / 2;                  // Date column width
$sizecolumn = $datecolumn;                      // File Size Column width
global $co_filename;
global $co_filename_sorted;

$coi=0;
$coj=0;
$cok=0;
$com=0;

if(isset($_GET['st']))
{
  $st = $_GET['st'];
}
else
{
  $st = 1;
}

if(isset($_GET['order']))
{
  $order = "SORT_".$_GET['order'];
}
else
{
  $order = "SORT_ASC";
}  

// Table Title row -------------------------------

echo "<table width=\"$tablewidth\" cellpadding=\"3\" cellspacing=\"1\"><tr>";

while ($cok < $columns)
{
echo "<td bgcolor=#666 width=$namecolumn align=center><font color=#000000>";
echo "    <table border=0 cellpadding=0 cellspacing=0>";
echo "    <tr>";
echo "        <td rowspan=2><a href=\"index.php?st=1\"><b>Nom de fichier</b><a/>  </td>";
echo "        <td><a href=\"index.php?st=1&order=ASC\"><img src=\"images/arrow_up.gif\" border=0></a></td>";

$cok++;
}

echo "</tr>";

$handle = opendir($co_filedir); 

while (false !==($file = readdir($handle)))
{ 
    if ($file != "." && $file != "..") 
    {

        $co_filename[$coi][3] = round(filesize($co_filedir.$file)/1024);
++$coi;
    }
}

closedir($handle);

// Sorting --------------------------------------------

$co_filename_sorted = csort($co_filename, $order, $st);

// End of Sorting -------------------------------------

while($com<(count($co_filename)))
{
