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="http://www.mamicode.com/Spiderman-City-Drive">        <img src="http://www.mamicode.com/thumb/12/Spiderman-City-Drive.jpg" >        <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="http://www.mamicode.com/Spiderman-City-Raid">        <img src="http://www.mamicode.com/thumb/12/Spiderman-City-Raid.jpg" >        <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 = http://www.mamicode.com/array(>

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。
