PHP中有关读写文本数据的一个小程序。_php记事本小程序、-优快云博客

本文链接：https://blog.youkuaiyun.com/zmouki/article/details/2292696

自已写的一个关于读写文本数据的小程序，主要功能如下：
1：填加商品信息
2：修改信息
3：删除信息
4：按价格高低排序
5：按填加商品的时间排序
6：分页功能（为程序更显而易见，把这个写在两个文件里，实际项目中不推荐这么写）
7：提供前能展示页面和后台管理页面
8：后台登陆HTTP验证功能（未实现，更新中）
以上所有数据均存放在record.txt文本当中。

文件描述

main.php模板引擎配置路径文件，shop.php后台管理员程序，shopmsg.html页面模板文件，show.php前台展示程序，shomsg.html前台页面模板文件，buymsg.php商品详细信息程序，buymsg.html商品详细信息页面模板文件，pg.php前台显示中使用的分页文件，pgshop.php后台管理中用到的分页文件。

实现方法

简单说一下实现方法，PHP中对文本操作，打开－>操作－>关闭。操作的性质就取决于你打开的方式，书上讲了很多打开方式，其实就是两种：只读和写入，只读就不多说了，从字面意思上就已经知道他的全部了。现在就简单的说一下写入。写入时书上讲了10种方式，但其实只有四种：追加，重写，二进制和用于与其他模工的结合模式。今天我们用到的只有前两种，添加新数据时用追加，这样之前所添加的数据的数据就不会被删除（fopen(“record.txt”，'a'))，相关使用方法见http://www.php.net。重写，就是把原有的所有数据全部清空后再添加进新的数据，根据这个原理，我们以修改后的数组中的数据作为数据源就可对文本进行修改操作了。关于删除，PHP中我没有找到相关删除的操作，所以在此我就对数据行最后的删除标记进行操作，如果是0就是没有被删除的，如果是1就是刚刚删除掉的，之后在读入数据时判断该项是否是0就可以实现数据的删除操作，好了，程序的实现方法就简单说到这里，下面是我的源码，如有不妥之处，请在下方留言，或发Mail至zmouki@gmail.com，共同讨论。
希望这个能对更多初次接触PHP对文本操作的朋友有所帮助。
