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：
复制代码 代码如下:
<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：
复制代码 代码如下:
<?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：
复制代码 代码如下:
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。
