powerpoint template silently and simply wrote a template engine-PHP Tutorial-php.cn

Engine file

Copy code The code is as follows:

/**
* An OOP template engine developed by Momo based on Discuz template engine, which can support template caching and generate hash md5 values.由hash值来判断模板是否被修改，假如被修改则重新生成缓存文件，假如没有被修改，则直接调用缓存文件.
* 版本:1.0.0.1 beta 测试版

你好 {else} 谢谢 {/if}

这个模板是默默今天下午写的,写的比较仓促,也许存在漏洞,这个版本只是测试版,以后我会逐渐的去完善,先发出来,当作一个前瞻.

以上就介绍了powerpoint 模板默默简单的写了一个模板引擎，包括了powerpoint 模板方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
