Does anyone know what the conn.php file is in the PHP voting system case?

Looking at the file name, it looks a bit like connecting to the database.
You can send the contents of the file and take a look
就是include里面的conn.php <?php include('../conn.php'); if(isset($_post['votename'])?$_post['votename']:""){ $votename = $_post['votename']; $diedate = $_post['dieddate']; $description = $_post['description']; $type = $_post['mradio']; $result = $db->query("update sysconfig set vote_name='$votename', dietime='$diedate', method='$type', description='$description' where cid='1';"); if($result){ echo "<script>onload = function(){document.getElementById('errortext').innerHTML='配置保存成功';}</script>"; }else{ echo "<script>onload = function(){document.getElementById('errortext').innerHTML='配置保存失败';}</script>"; } } $result = $db->query("select * from sysconfig where cid='1';"); $row = mysqli_fetch_assoc($result); ?> <!DOCTYpE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <script type="text/javascript" src="js/jquery.min.js"></script> <script type="text/javascript" src="js/Calendar3.js"></script> <link rel="stylesheet" href="css/add.css" type="text/css" media="screen" /> <link rel="stylesheet" href="utilLib/bootstrap.min.css" type="text/css" media="screen" /> </head> <body> <div class="div_from_aoto" style="width: 500px; margin:30px 40px;"> <div id="result111" class="result111" style="width:300px; height:20px; margin:4px auto; color:#33FF99;"> <h5 id="errortext"></h5> </div> <form action="Voteset.php" method="post" enctype="multipart/form-data" name="form1" id="form1"> <div class="control-group"> <label class="laber_from">投票主题</label> <div class="controls" ><INpUT class="username" name="votename" type=text value="<?php echo $row['vote_name']; ?>"><p class=help-block></p></div> </div> <div class="control-group"> <label class="laber_from">投票描述</label> <div class="controls" > <textarea name="description" cols="" rows="" ><?php echo $row['description'];?></textarea> <p class=help-block></p> </div> </div> <div class="control-group"> <label class="laber_from">投票终止时间</label> <div class="controls" > <input name="dieddate" type="text" value="<?php echo $row['dietime']; ?>" id="control_date" size="10" maxlength="10" onClick="new Calendar().show(this);" readonly="readonly" /> <p class=help-block></p> </div> </div> <div class="control-group"> <label class="laber_from" ></label> <div class="controls" ><button class="btn btn-success" style="width:80px;" >保存配置</button> </div> </div> </form> </div> </body> </html>
