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。
