我现在能通过查询指定的文字，跳转到指定的界面，但是如何通过搜索起始时间找到我需要的数据。
<?php
$search = $_POST['search']; //接收搜索框中的内容
function skip($url,$pic,$message){
$html=<<<A
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="utf-8" />
<meta http-equiv="refresh" content="1;URL={$url}" />
<title>正在跳转中</title>
<link rel="stylesheet" type="text/css" href="style/remind.css" />
</head>
<body>
<div class="notice"><span class="pic {$pic}"></span> {$message} <a href="{$url}">1秒后自动跳转中!</a></div>
</body>
</html>
A;
echo $html;
exit();
}
switch ($search )
{
case "温度":
skip('graphics/temperature.html','ok','查询成功！');
break;
case "湿度":
skip('graphics/humidity.html','ok','查询成功！');
break;
case "光照":
skip('graphics/light.html','ok','查询成功！');
break;
case "空气质量":
skip('graphics/quality.html','ok','查询成功！');
break;
default:
skip('main.html','ok','请正确输入查询条件！');
}
?>
