phpQuery对数据信息的采集进一步学习

前提：需要下载：phpQuery/phpQuery.php

链接：http://www.cnblogs.com/wuheng1991/p/5145398.html

1.对于规则的部分

<?php

header('Content-Type:text/html;charset=UTF-8');

include './phpQuery/phpQuery.php';

set_time_limit(10000);

$id = isset($_GET['id']) ? intval($_GET['id']) : 1;

if($id > 46){

   echo "finish!";

   exit;

}

// exit;

echo "当前 id=".$id;

echo "<br/>";

$url = "http://www.genetex.com/web/Search/SearchList.aspx?&Category=494&Page=".$id."&SpecialGroupID=240";

echo "当前的URL：";

echo $url."<br/>";

phpQuery::newDocumentFile($url);

$artList = pq(".sear_list");

$count = count($artList);

// var_dump($count);

$i = 0;

foreach($artList as $li){

    $url = '';

    $tr = '';

    $tr = pq($li)->eq(0)->find("li")->eq(1)->find("a")->attr('href');

    $tr = trim($tr);

    // var_dump($tr);

    $url = "http://www.genetex.com/";

    $arr = explode("/",$tr);

    // exit;

    $end = trim($arr[2]);

    $rel_url = $url.$end;

    $rel_url = $rel_url."\r\n";

    file_put_contents('url.txt',$rel_url,FILE_APPEND); //用于装载执行失败的数据

    echo '<br/>';

}

?>

<script>

function JumpUrl(){

setTimeout(JumpUrl,0);

3.对知识点的补充

a.使用phpQuery采集数据，实际上是通过链接地址，找到源码，再将源码转换为jQuery语法。然后通过jQuery语法获得数据

b.对于规则的部分，采集数据较容易。

c.对于不规则的部分，需要进行判断，较为复杂些，不过如果jQuery学的好，这也不是难事。

d.对函数：fputcsv() 的学习总结。如：

$fp = fopen('file.csv', 'a');

fputcsv($fp,$arrAll);

其中，$arrAll是一维数组。fputcsv(),会将函数的值写入到csv文件中，一次写一行，如果数组为空，则不会写入，一旦数组中的元素不为空，就可以写入。

参看：http://php.net/manual/zh/function.fputcsv.php
