Concaténer l'url de son fichier uploader

Bonjour, j'ai regarder sur plusieurs forum des sujets liés à mon problème mais je ne comprend pas! Donc je post ici:

Mon souci:
J'ai des fichiers uploader dans un dossier _admin/upload, par le biais d'une fonction "

move_uploded_file

"

Cependant j'aimerais afficher le contenu de ce dossier donc les images les pdf qui se trouve dedans dans mes pages de mon site via ma base de donnée MySql.

Le problème j'y arrive pas. Je connais pas la syntaxe donc je vous mets ci-dessous mon fichier php qui gère l'upload
Ma page galerie photo ou je dois afficher les photos via ma base de donnée en allant chercher mes photos dans le dossier _admin/upload

J'ai entendu dire qu'il fallait "concaténer" des variables pour afficher le chemin complet de l'image... Mais je ne sais pas faire! et je comprends pas trop.

Mon code Php:

<?php /*?><?php error_reporting(-1)?><?php */?>
<?php

//	---------------------------------------------
//	Pure PHP Upload version 1.1

if (phpversion() > "4.0.6") {

}
define("MAX_SIZE",0);
define("DESTINATION_FOLDER", "../_admin/upload");
define("no_error", "sucess.php");
define("yes_error", "error.php");
$_accepted_extensions_ = "pdf,doc,docx,png,jpg";
if(strlen($_accepted_extensions_) > 0){
	$_accepted_extensions_ = @explode(",",$_accepted_extensions_);
} else {
	$_accepted_extensions_ = array();
}
/*	modify */
if(!empty($HTTP_POST_FILES['dl_fichier'])){
	if(is_uploaded_file($HTTP_POST_FILES['dl_fichier']['tmp_name']) && $HTTP_POST_FILES['dl_fichier']['error'] == 0){
		$_file_ = $HTTP_POST_FILES['dl_fichier'];
		$errStr = "";
		$_name_ = $_file_['name'];
		$_type_ = $_file_['type'];
		$_tmp_name_ = $_file_['tmp_name'];
		$_size_ = $_file_['size'];
		if($_size_ > MAX_SIZE && MAX_SIZE > 0){
			$errStr = "File troppo pesante";
		}
		$_ext_ = explode(".", $_name_);
		$_ext_ = strtolower($_ext_[count($_ext_)-1]);
		if(!in_array($_ext_, $_accepted_extensions_) && count($_accepted_extensions_) > 0){
			$errStr = "Estensione non valida";
		}
		if(!is_dir(DESTINATION_FOLDER) && is_writeable(DESTINATION_FOLDER)){
			$errStr = "Cartella di destinazione non valida";
		}

			if(@move_uploaded_file($_tmp_name_,DESTINATION_FOLDER . "/" . $_name_)){
				header("Location: " . no_error);
			} else {
				header("Location: " . yes_error);
			}
		} else {
