php实现小说阅读功能的方法:1、解析TXT文件,生成章节内容;2、获取章节列表,实现获取章节内容接口即可。 本文操作环境:Windows7系统、PHP7.1版,DELL G3电脑 php怎么实现小说阅读功能? php实现TXT小说章节解析、小说章节在线阅读 要实现TXT文本章节的解析,大概思路是在每个章节加入了特定的字符,然后根据字符的起始位置读取章节。这里我写了一个小说阅读项目,也是根据这个思路进行。 实现步骤: 一. 解析TXT文件,生成章节内容 1. 编辑TXT文件,在每个章节名称加入我自己定义的一个字符串,用以识别。 2.识别章节,获取到章节列表 3.根据自定义的字符串,循环读取每个章节的内容,并生成每个章节的TXT文件 二.获取章节列表,实现获取章节内容接口 1. 章节列表接口 2. 章节内容接口 源码: 1.解析TXT文件,生成章节内容 2.获取章节列表,实现获取章节内容接口 推荐学习:《PHP视频教程》 以上就是php怎么实现小说阅读功能的详细内容,更多请关注gxlsystem其它相关文章!<?php
