Introduction

How to easily parse html code in php is probably a problem that every phper will encounter. Using phpQuery, you can make php process html code as conveniently as jQuery.

Project address: https://code.google.com/p/phpquery/

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

DEMO

Download library file: https://code.google.com/p/phpquery/downloads/list

I downloaded the onefile version: phpQuery-0.9.5.386-onefile.zip

Official demo: https://code.google.com/p/phpquery/source/browse/branches/dev/demo.php

Then reference it in the project.

html file test.html:

<span><</span><span>div </span><span>class</span><span>="thumb"</span><span> id</span><span>="Thumb-13164-3640"</span><span> style</span><span>="position: absolute; left: 0px; top: 0px;"</span><span>></span>
    <span><</span><span>a </span><span>href</span><span>="/Spiderman-City-Drive"</span><span>></span>

php processing:

<?<span>php
    </span><span>include</span>('phpQuery-onefile.php'<span>);
    
    </span><span>$filePath</span> = 'test.html'<span>;
    </span><span>$fileContent</span> = <span>file_get_contents</span>(<span>$filePath</span><span>);
    </span><span>$doc</span> = phpQuery::newDocumentHTML(<span>$fileContent</span><span>);
    phpQuery</span>::selectDocument(<span>$doc</span><span>);
    </span><span>$data</span> = <span>array</span><span>(
        </span>'name' => <span>array</span>(),
        'href' => <span>array</span>(),
        'img' => <span>array</span><span>()
    );
    </span><span>foreach</span> (pq('a') <span>as</span> <span>$t</span><span>) {
        </span><span>$href</span> = <span>$t</span> -> getAttribute('href'<span>);
        </span><span>$data</span>['href'][] = <span>$href</span><span>;
    }
    </span><span>foreach</span> (pq('img') <span>as</span> <span>$img</span><span>) {
        </span><span>$data</span>['img'][] = <span>$domain</span> . <span>$img</span> -> getAttribute('src'<span>);
    }
    </span><span>foreach</span> (pq('.GameName') <span>as</span> <span>$name</span><span>) {
        </span><span>$data</span>['name'][] = <span>$name</span> -><span> nodeValue;
    }
    </span><span>var_dump</span>(<span>$data</span><span>);
</span>?>

The above code includes fetching attributes and innerText content (fetched through nodeValue).

Output:

<span>array</span> (size=3<span>)
  </span>'name' => 
    <span>array</span> (size=2<span>)
      </span>0 => <span>string</span> 'Spiderman City Drive' (length=20<span>)
      </span>1 => <span>string</span> 'Spiderman - City Raid' (length=21<span>)
  </span>'href' => 
    <span>array</span> (size=2<span>)
      </span>0 => <span>string</span> 'http://www.gahe.com/Spiderman-City-Drive' (length=40<span>)
      </span>1 => <span>string</span> 'http://www.gahe.com/Spiderman-City-Raid' (length=39<span>)
  </span>'img' => 
    <span>array</span> (size=2<span>)
      </span>0 => <span>string</span> 'http://www.gahe.com/thumb/12/Spiderman-City-Drive.jpg' (length=53<span>)
      </span>1 => <span>string</span> 'http://www.gahe.com/thumb/12/Spiderman-City-Raid.jpg' (length=52)

The most powerful one is the pq selector, its syntax is similar to jQuery, which is very convenient.

The above introduces how to use phpQuery to parse html code like jquery, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
