Creating two links with an Explode path

I'm developing a project and next to the form, the user can upload a file. In the case, the registration part next to the upload (s) I have already been able to do, now I am creating the view / change of the record. And that's what I'm packing.

In case, I registered the upload path and threw it in the bank bringing this path to the display / change screen with explode to split the files ... but even with explode, it still understands as a link only. As shown below.

<? 

#definir o char-set da página 
setlocale(LC_ALL,"pt_BR"); 
header('Content-type: text/html; charset=windows-1252');    

set_time_limit(120); //Tempo limite de execução 
ERROR_REPORTING (E_ERROR); //Exibe somente erros fatais 

 #Variáveis de Data e Hora  
$dataAt = date('d/m/Y');    
$horaAt = date('H:i:s');

$inserir = 0;   

$usuario = strtolower($_SERVER["LOGON_USER"]);
$usuario_1 = split('\\', $usuario);
$usuario = $usuario_1[1];



//variaveis para execução do SQL 
SQL(); 
global $sql; 

$idd = $_REQUEST["id"];//Varíavel para buscar o campo id do registro 

//echo "O ID para alteração é o: ".$idd; 
//echo "<BR><BR>"; 

#Cria a consulta inicial 
$altEve = "SELECT [id],[mudanca],[tarefa]
  ,[descricao],[ambiente],[empresa],[reg_afet]
  ,[sist_afet],[hw_afet],[host_name],[serv_afet]
  ,[conclusao],[obs],[data_exec],[obs2],[upload]
    FROM [Passagem].[dbo].[tb_eventos_relev_tst] WHERE ID= $idd"; 

//echo $altPas;
//echo "<BR>";

#realiza a busca pelos dados do registro 
$result = $sql->execute($altEve); 
    if($tbl = $result) 
        { 
            $codigo = $tbl["id"];
            $codigo = $tbl["mudanca"];
            $codigo = $tbl["tarefa"];
            $codigo = $tbl["descricao"];
            $codigo = $tbl["ambiente"];
            $codigo = $tbl["empresa"];
            $codigo = $tbl["reg_afet"];
            $codigo = $tbl["sist_afet"];
            $codigo = $tbl["hw_afet"];
            $codigo = $tbl["host_name"];
            $codigo = $tbl["serv_afet"];
            $codigo = $tbl["conclusao"];
            $codigo = $tbl["obs"];
            $codigo = $tbl["obs2"];
            $codigo = $tbl["data_exec"];
            $codigo = $tbl["upload"];
            } 
    else 
        { echo "Registro não localizado"; } 

    #Inicia o tratamento dos registros      
    while (!$result -> EOF) { 
        $id = $result->Fields['id']->Value; 
        $mudanca = $result->Fields['mudanca']->Value;   
        $tarefa = $result->Fields['tarefa']->Value;     
        $descricao = $result->Fields['descricao']->Value;   
        $ambiente = $result->Fields['ambiente']->Value;     
        $empresa = $result->Fields['empresa']->Value;   
        $reg_afet = $result->Fields['reg_afet']->Value;     
        $sist_afet = $result->Fields['sist_afet']->Value;   
        $hw_afet = $result->Fields['hw_afet']->Value;   
        $host_name = $result->Fields['host_name']->Value;   
        $serv_afet = $result->Fields['serv_afet']->Value;   
        $conclusao = $result->Fields['conclusao']->Value;   
        $obs = $result->Fields['obs']->Value;   
        $data_exec = $result->Fields['data_exec']->Value;   
        $obs2 = $result->Fields['obs2']->Value;     
        $upload = $result->Fields['upload']->Value;     


        $dataEx = substr($data_exec, 8,2)."/".substr($data_exec,5,2)."/".substr($data_exec, 0,4);

        //echo $upload;
        //echo "<BR>";
        $uploadExi = explode(' , ',$upload); 
         //foreach($uploadExi as $valores) 
            //{ 
                //echo $valores.'<BR>'; 
            //}


        #Move para o registro seguinte
        $result->MoveNext();

    } 

And in the Html below

 ...
 <p>
                <label>Anexo:</label>
                <input type="hidden" name="eveArquivoAntigo" id="idArquivoAntigo" value="<? echo $upload; ?>" /> 
                <? 
                    if($upload == '' || $upload == 'Sem arquivo anexo') { 
                        echo 'Não existem arquivos anexos para este registro'; 
                    } else { 
                 ?> 
                    <a href="../UTILS/<?foreach($uploadExi as $valores) { echo $valores; } ?>" target="_blank">
                    <?foreach($uploadExi as $valores)   { echo $valores.'<BR>'; }?></a><br> 
                <?  
                    } 
                ?>
            </p>
            <p> 
                <label for="idArquivo">Alterar anexo:</label>
                <input type="file" name="eveArquivo[]" id="idArquivo" disabled />
            </p><br>

In the case what could be done so that each part of the file is handled with a different link? And taking advantage of the change (field below) the old file will probably have to be deleted from the server ... is there any way other than Ulink?
