Try the code below, I think you just missed you return the values:

    <?php

    function ret($valor, $tamanho, $orienta) {
      if ($orienta == 0){
          return str_pad($valor, $tamanho, "0", STR_PAD_LEFT);
      }
      else {
          return str_pad($valor, $tamanho, " ", STR_PAD_RIGHT);
      }
    }

    $teste = ret("37250468", 14, 0);
    echo $teste;
