PHP采集静态页面并把页面下载css,img,js保存

这是一个可以获取网页的html代码以及css,js,font和img资源的小工具,主要用来快速获取模板,如果你来不及设计UI或者看到不错的模板,则可以使用这个工具来抓取网页和提取资源文件,提取的内容会按相对路径来保存资源,因此你不必担心资源文件的错误url导入.

首页 index.php,代码如下:

<!DOCTYPE html>

<html>

<head>

<meta name="author" content="flute" />

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>网页抓取器</title>

<link rel="stylesheet" href="main.css" media="all" />

<script type="text/javascript" src="jquery.js"></script>

<script type="text/javascript" src="main.js"></script>

</head>

<body>

<h1>Web Grabber</h1>

<hr />

<div class="box">

  <h2>Url</h2>

  <div class="form">

    <input type="text" id="project" value="projectname" />

    <input type="text" id="url" value="http://" size="60" />

    <button class="submit" type="button">Get</button><span id="tip"></span>

  </div> www.phpfensi.com

</div>

<div class="box">

  <span class="all" id="saveall">Save All</span>

  <h2>List</h2>

  <ul id="list">

  </ul>

</div>

</body>

</html>

抓取页面代码 grab.php,代码如下:

<?PHP

/*

* flute

* 2014/03/31

*/

if(isset($_POST['url'])) {

  if(isset($_POST['project']) && !is_dir($_POST['project'])) mkdir($_POST['project'], 0777);

  echo json_encode(grab($_POST['url']));

}

function grab($url) {

  //$url = 'http://ldixing-wordpress.stor.sinaapp.com/uploads/leaves/test.html';

  $data = array();

  $file = preg_replace('/^.*//', '', $url);

  if(($content = file_get_contents($url)) !== false) {

   if(isset($_POST['project'])) file_put_contents($_POST['project'].'/'.$file, $content);

   $pattern = '/<link.*?href=('|")(.*?.css)1.*?>/i';

   if(preg_match_all($pattern, $content, $matches)) {

    $data['css'] = $matches[2];

   }

   $pattern = '/<script.*?src=('|")(.*?.js)1.*?>/i';

   if(preg_match_all($pattern, $content, $matches)) {

    $data['js'] = $matches[2];

   }

   $pattern = '/<img.*?src=('|")(.*?)1.*?>/i';

   if(preg_match_all($pattern, $content, $matches)) {

    $data['img'] = $matches[2];

   }

   $pattern = '/url(('|"|s)(.*?)1)/i';

   if(preg_match_all($pattern, $content, $matches)) {

    $data['src'] = $matches[2];

   }

  }

  return $data;

}

function vardump($obj) {

  echo '<pre>';

  print_r($obj);

  echo '</pre>';

}

?>

保存css,js,img等资源的页面 save.php,代码如下:

<?PHP

/*

*  flute

*  2014/03/31

*/

if(isset($_POST['url']) && isset($_POST['project']) && isset($_POST['domain'])) {

  extract($_POST);

  $url = preg_replace('/?.*$/', '', $url);

  $file = $url;

  $arr = explode('/', $file);

  $length = sizeof($arr);

  $filename = $arr[$length - 1];

  $root = $project;

  $dir = $root;

  if($domain == 'http') {

   $dir = $root.'/http';

   if(!is_dir($dir)) mkdir($dir, 0777);

  } else {

   $file = $domain.'/'.$url;

   for($i = 0; $i < $length -1; $i++) {

    if(!emptyempty($arr[$i])) {

     $dir .= '/'.$arr[$i];

     if(!is_dir($dir)) mkdir($dir, 0777);

    }//开源代码phpfensi.com

   }

  }

  if(!file_exists($dir.'/'.$filename) || filesize($dir.'/'.$filename) == 0) {

   $content = file_get_contents($file);

   file_put_contents($dir.'/'.$filename, $content);

  }

}

?>
