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
1 <?php 2 header("content-type:text/html;charset=utf-8"); 3 4 $artName = $_GET["artname"]; 5 6 if(!$artName){ 7 echo "文件名没有哦";exit(); 8 } 9 10 $fromFileName = "../".$artName.".txt"; 11 if(!file_exists($fromFileName)){ 12 echo "源文件不存在啊";exit(); 13 } 14 15 $distDirName = $artName; 16 17 $myfile = fopen($fromFileName, "r") or die("Unable to open file!"); 18 $content = fread($myfile,filesize($fromFileName)); 19 fclose($myfile); 20 echo "<br>读取原始文件成功.............."; 21 22 $pattern='/#titlestart#(.*?)#titleend#/is'; 23 preg_match_all ($pattern, $content, $result, PREG_PATTERN_ORDER); 24 25 echo "<br><br>文章目录识别成功..............<br><br>"; 26 27 // 获取到目录 28 // 目录数组 $result[1] 29 $catalogStr = ""; 30 $catalogArr = array(); 31 foreach($result[1] as $v){ 32 array_push($catalogArr,$v); 33 $catalogStr .= $v."#catalog#"; 34 } 35 36 // 创建书本目录 37 $dir = iconv("UTF-8", "GBK", "./books/".$distDirName); 38 if (!file_exists($dir)){ 39 mkdir ($dir,0777,true); 40 echo '<br>创建文件夹bookdir成功<br><br>'; 41 } else { 42 echo '<br>需创建的文件夹bookdir已经存在<br><br>'; 43 } 44 45 // 生成目录文件 46 $myfile = fopen($dir."/catalog.txt", "w") or die("Unable to open file!"); 47 fwrite($myfile, $catalogStr); 48 fclose($myfile); 49 echo "<br>==============================目录文件生成成功..............<br>"; 50 51 // 获取到内容，写入文件 52 foreach($catalogArr as $k=>$v){ 53 $pattern='/#titlestart#'.$v.'#titleend#(.*?)#titlestart/is'; 54 preg_match ($pattern, $content, $result); 55 56 $myfile = fopen($dir."/".($k+1).".txt", "w") or die("Unable to open file!"); 57 fwrite($myfile, $result[1]); 58 fclose($myfile); 59 echo "<br>===================文章第".($k+1)."章节写入成功.............."; 60 } 61 62 63 echo "<br><br><br><br><br><br><br>====================书本识别成功..........................."; 64 65 66 67 ?>
2.获取章节列表，实现获取章节内容接口
1 <?php 2 header('Content-Type:application/json'); 3 4 $action = $_GET["act"]; 5 $fileName = $_GET["artname"]; 6 7 if(!$action){ 8 $rsp = array("code" => 500, "msg" => "请求不存在"); 9 $rsp = json_encode($rsp); 10 echo $rsp; 11 exit(); 12 }else if(!$fileName){ 13 $rsp = array("code" => 500, "msg" => "书本不存在"); 14 $rsp = json_encode($rsp); 15 echo $rsp; 16 exit(); 17 } 18 19 if($action == "getcat"){ 20 // 获取目录 21 $fileName = "../books/".$fileName."/catalog.txt"; 22 23 // 读取文件 24 if(file_exists($fileName)){ 25 $myfile = fopen($fileName, "r") or die("Unable to open file!"); 26 $content = fread($myfile,filesize($fileName)); 27 fclose($myfile); 28 29 $code = 200; 30 $msg = "读取目录成功"; 31 $catalogArray = array(); 32 if($content){ 33 $carray = explode('#catalog#',$content); 34 35 foreach($carray as $k=>$v){ 36 if($v){ 37 $item = array("index"=>($k+1), "cataTitle"=>$v); 38 array_push($catalogArray, $item); 39 } 40 } 41 } 42 43 if(count($catalogArray)<=0){ 44 $code = 500; 45 $msg = "书本不存在目录"; 46 } 47 48 $rsp = array("code" => $code, "msg" => $msg, "catalogList" => $catalogArray); 49 $rsp = json_encode($rsp); 50 51 echo $rsp; 52 exit(); 53 }else{ 54 // 文件不存在 55 $rsp = array("code" => 404, "msg" => "文件不存在"); 56 $rsp = json_encode($rsp); 57 echo $rsp; 58 exit(); 59 } 60 }else if($action=="getcon"){ 61 // 获取文章内容 62 $index = (int)$_GET["index"]; 63 64 $fileName = "../books/".$fileName."/".$index.".txt"; 65 66 if(file_exists($fileName)){ 67 $myfile = fopen($fileName, "r") or die("Unable to open file!"); 68 $content = fread($myfile,filesize($fileName)); 69 fclose($myfile); 70 71 $content = str_replace("\r\n","<br>", $content); 72 $rsp = array("code" => 200, "msg" => "读取内容成功", "con" => $content); 73 $rsp = json_encode($rsp); 74 75 echo $rsp; 76 exit(); 77 }else{ 78 // 文件不存在 79 $rsp = array("code" => 404, "msg" => "文件不存在"); 80 $rsp = json_encode($rsp); 81 echo $rsp; 82 exit(); 83 } 84 }else{ 85 echo "error request, please check your request content"; 86 exit(); 87 } 88 89 90 ?>
