Smarty变量调节器的使用

$str = 'how Are you';
$smarty->assign('str', $str);

$title = "\nbbbbbb。bbbb\n1111111\nbbbbbbbb\n222.\t22.22";
$smarty->assign('title',$title);

$name = "who are \n you?";
$smarty->assign('name',$name);

$address = "<center>I'm center</center><sm>ddddddd</sm>";
$smarty->assign('address',$address);

$smarty->assign('leg',$leg);

$file = "hi who are you where are from";
$smarty->assign('file',$file);

$num = 123.4567;
$smarty->assign('num',$num);

$content = "hit me <a href='#'>this is a test</a><?c=admin&a=input>[email protected]";
$smarty->assign('content',$content);

$smarty->display('index.html');		//显示index.html
