phpQuery를 사용하여 jquery와 같은 HTML 코드를 구문 분석합니다.

소개

PHP에서 HTML 코드를 쉽게 구문 분석하는 방법은 아마도 모든 PHPer가 직면하게 될 문제일 것입니다. phpQuery를 사용하면 jQuery만큼 편리하게 PHP 프로세스 HTML 코드를 만들 수 있습니다.

php 처리:

    </span><span>$filePath</span> = 'test.html'<span>;
    </span><span>$fileContent</span> = <span>file_get_contents</span>(<span>$filePath</span><span>);

        'href' => <span>array</span>(),

        </span><span>$data</span>['name'][] = <span>$name</span> -><span> nodeValue;
    }
    </span><span>var_dump</span>(<span>$data</span><span>);
</span>?>

위 코드에는 속성 및 innerText 콘텐츠 가져오기(nodeValue를 통해 가져오기)가 포함되어 있습니다.

출력:

<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)

가장 강력한 것은 pq 선택기입니다. 구문은 jQuery와 유사하여 매우 편리합니다.
