Why does Unlink not work on this script?

What you see below is a part of my script.

The problem is that I need only the re-sized thumb image and not the original file. The image won't re-size if it is not uploaded, therefore the process should look like this:

Now this last part (deletion) does not work. I get this error:

PHP Warning: unlink($target_file) [function.unlink]: No such file or directory in /path/file.php on line X

It does not find it!

if (isset($_REQUEST['Submit'])) {

    mkdir($dirloc, 0755, true); 
    $i1=$_FILES['image']['name']; 
    $nw1="$dirloc/".$i1; 

    if ($i1) {
        $copy1 = copy($_FILES['image']['tmp_name'], $nw1);
    }

    $fileName = $_FILES["image"]["name"];
    $kaboom = explode(".", $fileName);
    $fileExt = end($kaboom);
    function ak_img_resize($target, $newcopy, $w, $h, $ext) {
        list($w_orig, $h_orig) = getimagesize($target);
        $scale_ratio = $w_orig / $h_orig;
        if (($w / $h) > $scale_ratio) {
            $w = $h * $scale_ratio;
        } else {
            $h = $w / $scale_ratio;
        }
        $img = "";
        $ext = strtolower($ext);
        if ($ext == "gif"){
            $img = imagecreatefromgif($target);
        } else if($ext =="png") {
            $img = imagecreatefrompng($target);
        } else {
            $img = imagecreatefromjpeg($target);
        }
        $tci = imagecreatetruecolor($w, $h);
        imagecopyresampled($tci, $img, 0, 0, 0, 0, $w, $h, $w_orig, $h_orig);
        imagejpeg($tci, $newcopy, 80);
    }
    $target_file = "$dirloc/$fileName";

    $resized_file = "$dirloc/thumb.$fileExt";
    $wmax = 150;
    $hmax = 150;
    ak_img_resize($target_file, $resized_file, $wmax, $hmax, $fileExt);
    $xxx = $resized_file;
    $delete_target_file = unlink('$target_file');    

    $sql = "INSERT INTO $db_table(path,code,timecode,catg,description,title) values 
            ('$xxx','".mysql_real_escape_string(stripslashes($_REQUEST['code']))."',
            '".mysql_real_escape_string(stripslashes($times))."',
            '".mysql_real_escape_string(stripslashes($_REQUEST['catg']))."',
            '".mysql_real_escape_string(stripslashes($_REQUEST['area2']))."',
            '".mysql_real_escape_string(stripslashes($_REQUEST['fbox']))."')";

    if($result = mysql_query($sql ,$db)) {
        $codes = $_REQUEST['code'];
        $linkto = "?v=$codes";
        echo "<script>window.location = '$linkto'</script>";
    } else { 
        echo "ERROR: ".mysql_error();
    }
} else {
    // Here comes the form 
}

Could someone explain why it doesn't delete it?

Be sure, $target_file holds the absolute path of the file. It seems that unlink cannot find the file you want to delete.

use double quotes or do not use any quote at all.

unlink("$target_file");

or

unlink($target_file);

Variable surrounded with single quote are not parsed you needs to surround them with double quotes or do not use quotes at all.
