Probleme pour modifier l'avatar

PHP

Bonjour, je voudrais faire en sorte qu'on puisse changer de photo de profil mais je ne sais pas comment proceder.
Voici le code :


$bdd = new PDO('mysql:host=127.0.0.1;dbname=espace_membre', 'root', '');

$redirec = 'membre-profil.php?id=' . $_SESSION['id'];

if (isset($_SESSION['id']) ) 
{
   $requser = $bdd->prepare("SELECT * FROM membre WHERE id = ?");
   $requser->execute(array($_SESSION['id']));
   $user = $requser->fetch();

   if (isset($_POST['newpseudo']) AND !empty($_POST['newpseudo']) AND $_POST['newpseudo'] != $user['pseudo']) 
   {
      $newpseudo = htmlspecialchars($_POST['newpseudo']);
      $insertpseudo = $bdd->prepare("UPDATE membre SET pseudo = ? WHERE id = ?");
      $insertpseudo->execute(array($newpseudo, $_SESSION['id']));
      header('Location: membre-profil.php?id=' . $_SESSION['id']);

      if(isset($_FILES['avatar']) AND !empty($_FILES['avatar']['name'])) {
        $tailleMax = 2097152;
        $extensionsValides = array('jpg', 'jpeg', 'gif', 'png');
        if($_FILES['avatar']['size'] <= $tailleMax) {
        $extensionUpload = strtolower(substr(strrchr($_FILES['avatar']['name'], '.'), 1));
        if(in_array($extensionUpload, $extensionsValides)) {
         $chemin = "membre/avatar/".$_SESSION['id'].".".$extensionUpload;
         $resultat = move_uploaded_file($_FILES['avatar']['tmp_name'], $chemin);
         if($resultat) {
            $updateavatar = $bdd->prepare('UPDATE membre SET avatar = :avatar WHERE id = :id');
            $updateavatar->execute(array(
               'avatar' => $_SESSION['id'].".".$extensionUpload,
               'id' => $_SESSION['id']
               ));
            header('Location: membre-profil.php?id='.$_SESSION['id']);
         } else {
            $msg = "Erreur durant l'importation de votre photo de profil";
         }
      } else {
         $msg = "Votre photo de profil doit être au format jpg, jpeg, gif ou png";
      }
   } else {
      $msg = "Votre photo de profil ne doit pas dépasser 2Mo";
   }
}
   }
