The example in this article describes the method of obtaining the Baidu snapshot date of the website in php. Share it with everyone for your reference. The details are as follows:
<html>
<head>
<title>在线演示_php获取某网站的快照时间</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="keywords" content="百度,baidu,查询快照结果">
<meta name="description" content="php查询网站快照日期: ">
</head>
<body>
<?php $k=isset($_POST['k'])?$_POST['k']:''; ?>
<form method="post" action="">
<h2>查询网站快照日期:</h2>
输入网址：<br />
http://<input type="text" name="k" size="60" value="<?php echo $k ?>">
<input type="submit" value="提交">
</form>
<?php

function getKuaiZhao($text) {
$url = 'http://www.baidu.com/s?word='.$text;
$html = file_get_contents($url);
$text = str_replace('.','\.',addslashes($text));
$search = '/<b>'.$text.'<\/b>[^<]*((?:19|20)[0-9]{2}-(?:1[012]|[1-9])-(?:[12][0-9]|3[01]|[1-9]))/';
preg_match($search, $html, $r);
//highlight_string($search);
return $r[1];
}
if($k=='') {
echo('请输入url');
}else{
if($r = getKuaiZhao($k)) {
echo '快照：'.$r;
}else {
echo('无快照');
}
}
?>
