用phpQuery像jquery一样解析html代码

简介

如何在php中方便地解析html代码，估计是每个phper都会遇到的问题。用phpQuery就可以让php处理html代码像jQuery一样方便。

项目地址：https://code.google.com/p/phpquery/

github地址：https://github.com/TobiaszCudnik/phpquery

DEMO

下载库文件：https://code.google.com/p/phpquery/downloads/list

我下的是onefile版：phpQuery-0.9.5.386-onefile.zip

官方demo：https://code.google.com/p/phpquery/source/browse/branches/dev/demo.php

然后在项目中引用。

html文件test.html：

<div class="thumb" id="Thumb-13164-3640" style="position: absolute; left: 0px; top: 0px;">

    <a href="/Spiderman-City-Drive">

        <img src="/thumb/12/Spiderman-City-Drive.jpg" alt="">

        <span class="GameName" id="GameName-13164-3640" style="display: none;">Spiderman City Drive</span>

        <span class="GameRating" id="GameRating-13164-3640" style="display: none;">

            <span style="width: 68.14816px;"></span>

        </span>

    </a>

</div>

<div class="thumb" id="Thumb-13169-5946" style="position: absolute; left: 190px; top: 0px;">

    <a href="/Spiderman-City-Raid">

        <img src="/thumb/12/Spiderman-City-Raid.jpg" alt="">

        <span class="GameName" id="GameName-13169-5946" style="display: none;">Spiderman - City Raid</span>

        <span class="GameRating" id="GameRating-13169-5946" style="display: none;">

            <span style="width: 67.01152px;"></span>

        </span>

    </a>

</div>

php处理：

<?php

    include('phpQuery-onefile.php');

    

    $filePath = 'test.html';

    $fileContent = file_get_contents($filePath);

    $doc = phpQuery::newDocumentHTML($fileContent);

    phpQuery::selectDocument($doc);

    $data = array(

        'name' => array(),

        'href' => array(),

        'img' => array()

    );

    foreach (pq('a') as $t) {

        $href = $t -> getAttribute('href');

        $data['href'][] = $href;

    }

    foreach (pq('img') as $img) {

        $data['img'][] = $domain . $img -> getAttribute('src');

    }

    foreach (pq('.GameName') as $name) {

        $data['name'][] = $name -> nodeValue;

    }

    var_dump($data);

?>

上面的代码中包含了取属性和innerText内容（通过nodeValue取）。

输出：

array (size=3)

  'name' => 

    array (size=2)

      0 => string 'Spiderman City Drive' (length=20)

      1 => string 'Spiderman - City Raid' (length=21)

  'href' => 

    array (size=2)

      0 => string 'http://www.gahe.com/Spiderman-City-Drive' (length=40)

      1 => string 'http://www.gahe.com/Spiderman-City-Raid' (length=39)

  'img' => 

    array (size=2)

      0 => string 'http://www.gahe.com/thumb/12/Spiderman-City-Drive.jpg' (length=53)

      1 => string 'http://www.gahe.com/thumb/12/Spiderman-City-Raid.jpg' (length=52)

强大的是pq选择器，语法类似jQuery，很方便。
