谈谈生成静态页面的一些经验
作者: q3boy
静态页面的生成一般有这么几个思路了。。
1。程序编写过程中。不使用直接输出的语句。而时将所有的输出连接至输出字符串，输出完成后。再直接将输出字符串内容写入文件
2。编写中按照正常的方式编写。通过ob函数组捕获输出。然后将输出写入文件
3。使用模板类时，用get/fetch一类的方法获取输出。并写入文件。
具体实现上又有这两种方法
1。管理后台添加记录时，直接生成目标html页面，并且前台调用连接直接指向生成的html页面。这种方法程优点是程序效率最高。服务器负荷轻，不过由于生成的是纯静态页面，一旦页面样式上有所改动就必须重新生成所有的内容页。所以实际使用中应用一般不是太多。更多的是使用js,ssi,xml/xsl等客户端手段，生成的静态文件中仅保存数据，不涉及样式，这样能达到速度和维护性的平衡，不过相对前后台程序要复杂些（应用这种方法时，由于内容为纯静态，可以搭配单独编译的纯静态的apache使用。。效率和资源占用上比包含动态内容支持的要更佳）
2。前台访问链接指向php程序，php程序首先检查是否存在相应的静态文件。如果静态文件不存在。则生成并重定向至此文件，否则直接重定向。这种方法实际使用中一般和apache的url_rewrite功能一起使用。将php的文件地址重为html的形式，有利于搜索引擎的检索。这种方法在效率上略有损失，不过程序结构简单，便于调整，在访问量不是很大时使用很合适。。
