phpQuery让php处理html代码像jQuery一样方便

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。
