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

<span></</span><span>a</span><span>></span>
<span></</span><span>div</span><span>></span>php处理：
<?<span>php
</span><span>include</span>('phpQuery-onefile.php'<span>);
</span><span>$filePath</span> = 'test.html'<span>;
</span><span>$fileContent</span> = <span>file_get_contents</span>(<span>$filePath</span><span>);

'href' => <span>array</span>(),

}
</span><span>foreach</span> (pq('img') <span>as</span> <span>$img</span><span>) {
</span><span>$data</span>['img'][] = <span>$domain</span> . <span>$img</span> -> getAttribute('src'<span>);
}
</span><span>foreach</span> (pq('.GameName') <span>as</span> <span>$name</span><span>) {
</span><span>$data</span>['name'][] = <span>$name</span> -><span> nodeValue;
}
</span><span>var_dump</span>(<span>$data</span><span>);
</span>?>上面的代码中包含了取属性和innerText内容（通过nodeValue取）。
输出：
<span>array</span> (size=3<span>)
</span>'name' =>
<span>array</span> (size=2<span>)
</span>0 => <span>string</span> 'Spiderman City Drive' (length=20<span>)
</span>1 => <span>string</span> 'Spiderman - City Raid' (length=21<span>)
</span>'href' =>
<span>array</span> (size=2<span>)
</span>0 => <span>string</span> 'http://www.gahe.com/Spiderman-City-Drive' (length=40<span>)
</span>1 => <span>string</span> 'http://www.gahe.com/Spiderman-City-Raid' (length=39<span>)
</span>'img' =>
<span>array</span> (size=2<span>)
</span>0 => <span>string</span> 'http://www.gahe.com/thumb/12/Spiderman-City-Drive.jpg' (length=53<span>)
</span>1 => <span>string</span> '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。
