Smarty 模板引擎：變量輸出完整指南（字符串、陣列、對象）

模板文件 show.tpl

<h1>Smarty 用例</h1>
<{$str}> <-- 字符串 -->
<{$integer}> <-- 整數 -->
<{$float}> <-- 浮點數 -->
<{$bool}> <-- 布爾值 -->

<-- 索引陣列 -->
<{$arr[0]}> <{$arr[1]}> <{$arr[2]}>

<-- 關聯陣列 -->
<{$arr2.city1}&> <{$arr2.city2}&> <{$arr2.city3}&>

<-- 二維索引陣列 -->
<{$arr3[0][0]}> <{$arr3[0][1]}> <{$arr3[0][2]}>
<{$arr3[1][0]}> <{$arr3[1][1]}> <{$arr3[1][2]}>

<-- 二維關聯陣列 -->
<{$arr4[0].id}&> <{$arr4[0].username}&> <{$arr4[0].pwd}&>
<{$arr4[1].id}&> <{$arr4[1].username}&> <{$arr4[1].pwd}&>

<-- 巢狀關聯陣列 -->
<{$arr5.emp1.id}&> <{$arr5.emp1.username}&> <{$arr5.emp1.pwd}&>

<-- 對象屬性 -->
<{$dog->name}&> <{$dog->age}&> <{$dog->color}&>
<{$dog->arr[0]}> <{$dog->arr[1]}> <{$dog->arr[2]}>
