用phpQuery像jquery一樣解析html代碼，phpqueryjquery

簡介

如何在php中方便地解析html代碼，估計是每個phper都會遇到的問題。用phpQuery就可以讓php處理html代碼像jQuery一樣方便。

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

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

DEMO

下載庫檔案：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

然後在項目中引用。

html檔案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 Drivespan>        <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 Raidspan>        <span class="GameRating" id="GameRating-13169-5946" style="display: none;">            <span style="width: 67.01152px;">span>        span>    a>div>

php處理：

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);?>

上面的代碼中包含了取屬性和innerText內容（通過nodeValue取）。

輸出：

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)

強大的是pq選取器，文法類似jQuery，很方便。
