ecshop代码详解之init.php，ecshopinit.php
在includes/init.php目录下
因为工作原因，需要对ecshop二次开发，顺便记录一下对ecshop源代码的一些分析：
首先是init.php文件，这个文件在ecshop每个页面都会 调用到，习惯就先分析它：
<br /><?<span>php

ob_start相关函数了解：
1、Flush：刷新缓冲区的内容，输出。
函数格式：flush()
说明：这个函数经常使用，效率很高。
2、ob_start ：打开输出缓冲区
函数格式：void ob_start(void)
说明：当缓冲区激活时，所有来自PHP程序的非文件头信息均不会发送，而是保存在内部缓冲区。为了输出缓冲区的内容，可以使用ob_end_flush()或flush()输出缓冲区的内容。
、ob_get_contents ：返回内部缓冲区的内容。
使用方法：string ob_get_contents(void)
说明：这个函数会返回当前缓冲区中的内容，如果输出缓冲区没有激活，则返回 FALSE 。
4、ob_get_length：返回内部缓冲区的长度。
使用方法：int ob_get_length(void)
说明：这个函数会返回当前缓冲区中的长度；和ob_get_contents一样，如果输出缓冲区没有激活。则返回 FALSE。
5、ob_end_flush ：发送内部缓冲区的内容到浏览器，并且关闭输出缓冲区。
使用方法：void ob_end_flush(void)
说明：这个函数发送输出缓冲区的内容（如果有的话）。
6、ob_end_clean：删除内部缓冲区的内容，并且关闭内部缓冲区
使用方法：void ob_end_clean(void)
说明：这个函数不会输出内部缓冲区的内容而是把它删除！
7、ob_implicit_flush：打开或关闭绝对刷新
使用方法：void ob_implicit_flush ([int flag])
说明：使用过Perl的人都知道$|=x的意义，这个字符串可以打开/关闭缓冲区，而ob_implicit_flush函数也和那个一样，默认为关闭缓冲区，打开绝对输出后，每个脚本输出都直接发送到浏览器，不再需要调用 flush()
