模板引擎该怎么学呢？
还没看smarty呢 看了一个自定义的模版引擎都看不懂 一大堆东西都不知道是什么意思 感觉太难了啊 该怎么学习呢？
图片里这些都看不懂什么意思呢
为什么尖括号里面还有花括号 还有下面图片的一大堆问题 为什么还用到了正则表达式呢？

我看得出题主是困于smarty相对于你复杂的语法结构，我给出的建议是：
不要太刻意去学习，你可以先接触一些框架，每个成熟的框架都包含了模板引擎，当然不一定是smarty，但是对你理解模板引擎有神助！~
PHP语言本身就是一个非常出色的模板引擎！！！
不建议使用smarty这样复杂的模板引擎。。。
推荐你到github上面找找一些小点的模板引擎。
这个官方的文档肯定有写的，其实就是一些特定的语法，大部分框架都有的，为了能让代码看起来更简洁一些
模板引擎就是抽象视图成模板，然后它根据传入的数据拼装成视图的东西，实际上php本身就是一个模板引擎，基本上所有的模板引擎都是差不多的，根据需要就行
