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

複製代碼 代碼如下:

<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處理

複製代碼 代碼如下:

<?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);
?>

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

輸出:

複製代碼 代碼如下:

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 'yun_qi_img/Spiderman-City-Drive.jpg' (length=53)
      1 => string 'yun_qi_img/Spiderman-City-Raid.jpg' (length=52)

強大的是pq選取器,文法類似jQuery,很方便。
