index.php

php"><?php
use ppt\tool\View;
$haha = 12;
$id = 111;
$arr = ['x','y',3];
$pp = ['x'=>['id'=>'1','name'=>'12'],'y'=>['id'=>'1','name'=>'12'],'z'=>['id'=>'1','name'=>'12'],
];
echo View::display('',['haha'=>$haha,'id'=>$id,'arr'=>$arr,'pp'=>$pp,]);
echo '123456';

index.html

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title>

<body>
{if($id===1)}
1
{/if}

2
{/else if}
{else}
other
{/else}
{foreach($arr as $item)}
{$item}
{/foreach}
