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
<?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(); } ?>
