smarty,该如何解决

smarty
include"libs/Smarty.class.php";
　 $smarty = new Smarty(); 
　　$smarty->template_dir ="tpls/templates";
　　$smarty->compile_dir ="tpls/templates_c";
　　$smarty->config_dir = "tpls/config";
　　$smarty->cache_dir ="tpls/cache";
  $tpl->left_delimiter = "　　$tpl->right_delimiter = "}>";

?>
报错：Parse error: syntax error, unexpected T_VARIABLE in E:\AppServ\www\test\smarty\main.php on line 3
第三行报错
那位大神给指教...

------解决方案--------------------
把全角的空格改成半角的就对了


include"libs/Smarty.class.php";
$smarty = new Smarty();
$smarty->template_dir ="tpls/templates";
$smarty->compile_dir ="tpls/templates_c";
$smarty->config_dir = "tpls/config";
$smarty->cache_dir ="tpls/cache";
$tpl->left_delimiter = " $tpl->right_delimiter = "}>";

------解决方案--------------------

探讨

第三行的空格是改成半角的仍然报错，报同样的错...

------解决方案--------------------
你复制出来的代码里面还有11个全角空格
请对全角空格做全文替换
