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：

　　　　1. 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

2.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

 <?php
 header("content-type:text/html;charset=utf-8");

 $artName = $_GET["artname"];

 if(!$artName){
     echo "文件名没有哦";exit();
 }

 $fromFileName = "../".$artName.".txt";
 if(!file_exists($fromFileName)){
     echo "源文件不存在啊";exit();
 }

 $distDirName = $artName;

 $myfile = fopen($fromFileName, "r") or die("Unable to open file!");
 $content = fread($myfile,filesize($fromFileName));
 fclose($myfile);
 echo "<br>读取原始文件成功..............";

 $pattern='/#titlestart#(.*?)#titleend#/is';
 preg_match_all ($pattern, $content, $result, PREG_PATTERN_ORDER);

 echo "<br><br>文章目录识别成功..............<br><br>";

 // 获取到目录
 // 目录数组 $result[1]
 $catalogStr = "";
 $catalogArr = array();
 foreach($result[1] as $v){
     array_push($catalogArr,$v);
     $catalogStr .= $v."#catalog#";
 }

 // 创建书本目录
 $dir = iconv("UTF-8", "GBK", "./books/".$distDirName);
 if (!file_exists($dir)){
     mkdir ($dir,0777,true);
     echo '<br>创建文件夹bookdir成功<br><br>';
 } else {
     echo '<br>需创建的文件夹bookdir已经存在<br><br>';
 }

 // 生成目录文件
 $myfile = fopen($dir."/catalog.txt", "w") or die("Unable to open file!");
 fwrite($myfile, $catalogStr);
 fclose($myfile);
 echo "<br>==============================目录文件生成成功..............<br>";

 // 获取到内容，写入文件
 foreach($catalogArr as $k=>$v){
     $pattern='/#titlestart#'.$v.'#titleend#(.*?)#titlestart/is';
     preg_match ($pattern, $content, $result);

     $myfile = fopen($dir."/".($k+1).".txt", "w") or die("Unable to open file!");
     fwrite($myfile, $result[1]);
     fclose($myfile);
     echo "<br>===================文章第".($k+1)."章节写入成功..............";
 }

 echo "<br><br><br><br><br><br><br>====================书本识别成功...........................";

 ?>

2.获取章节列表，实现获取章节内容接口

 <?php
 header('Content-Type:application/json');

 $action = $_GET["act"];
 $fileName = $_GET["artname"];

 if(!$action){
     $rsp = array("code" => 500, "msg" => "请求不存在");
     $rsp = json_encode($rsp);
     echo $rsp;
     exit();
 }else if(!$fileName){
     $rsp = array("code" => 500, "msg" => "书本不存在");
     $rsp = json_encode($rsp);
     echo $rsp;
     exit();
 }

 if($action == "getcat"){
     // 获取目录
     $fileName = "../books/".$fileName."/catalog.txt";

     // 读取文件
     if(file_exists($fileName)){
         $myfile = fopen($fileName, "r") or die("Unable to open file!");
         $content = fread($myfile,filesize($fileName));
         fclose($myfile);

         $code = 200;
         $msg = "读取目录成功";
         $catalogArray = array();
         if($content){
             $carray = explode('#catalog#',$content); 

             foreach($carray as $k=>$v){
                 if($v){
                     $item = array("index"=>($k+1), "cataTitle"=>$v);
                     array_push($catalogArray, $item);
                 }
             }
         }

         if(count($catalogArray)<=0){
             $code = 500;
             $msg = "书本不存在目录";
         }

         $rsp = array("code" => $code, "msg" => $msg, "catalogList" => $catalogArray);
         $rsp = json_encode($rsp);

         echo $rsp;
         exit();
     }else{
         // 文件不存在
         $rsp = array("code" => 404, "msg" => "文件不存在");
         $rsp = json_encode($rsp);
         echo $rsp;
         exit();
     }
 }else if($action=="getcon"){
     // 获取文章内容
     $index = (int)$_GET["index"];

     $fileName = "../books/".$fileName."/".$index.".txt";

     if(file_exists($fileName)){
         $myfile = fopen($fileName, "r") or die("Unable to open file!");
         $content = fread($myfile,filesize($fileName));
         fclose($myfile);

         $content = str_replace("\r\n","<br>", $content);
         $rsp = array("code" => 200, "msg" => "读取内容成功", "con" => $content);
         $rsp = json_encode($rsp);

         echo $rsp;
         exit();
     }else{
         // 文件不存在
         $rsp = array("code" => 404, "msg" => "文件不存在");
         $rsp = json_encode($rsp);
         echo $rsp;
         exit();
     }
 }else{
     echo "error request, please check your request content";
     exit();
 }

 ?>
