一个简单的、可扩展的PHP页面分析器。

分析HTML标记并提取常见的属性，例如

• 元标签，包括OpenGraph标签、Twitter Cards等
• JSON-LD
• 苹果图标 / favicon
• 规范引用
• 响应头
• RSS / XML源（链接替代）

通过添加自己的自定义分析器轻松扩展。

安装

composer require chrisshennan/page-analyzer dev-master

基本用法

分析实时页面

在创建PageAnalyzer时设置分析器列表。

$loader = require __DIR__.'/vendor/autoload.php';

$url ='https://shoutabout.it';

$analyzerFactory = new \Cas\PageAnalyzer\Factory\AnalyzerFactory();
$analyzerFactory->addAnalyzerReference('\Cas\PageAnalyzer\Analyzer\MetaData');
$analyzerFactory->addAnalyzerReference('\Cas\PageAnalyzer\Analyzer\Logo');

$analyzerManager = $analyzerFactory->createManager();
$analysisCollection = $analyzerManager->analyze($url)->getAnalysis();

$data = [];

foreach ($analysisCollection as $analyzer => $analysis) {
    $data[$analyzer] = $analysis->getData();
}

...

自定义分析器

创建新的分析器类

namespace App\Analyzer;

use Cas\PageAnalyzer\Analyzer\BaseAnalyzer;

class MyCustomAnalyzer extends BaseAnalyzer
{
    public function analyze(string $content) : array
    {
        ...
    }
}

将分析器添加到分析器列表中

$loader = require __DIR__.'/vendor/autoload.php';

$url ='https://shoutabout.it';

$analyzerFactory = new \Cas\PageAnalyzer\Factory\AnalyzerFactory();
$analyzerFactory->addAnalyzerReference('\Cas\PageAnalyzer\Analyzer\MetaData');
$analyzerFactory->addAnalyzerReference('\Cas\PageAnalyzer\Analyzer\Logo');
$analyzerFactory->addAnalyzerReference('\App\Analyzer\MyCustomAnalyzer');

$analyzerManager = $analyzerFactory->createManager();
$analysisCollection = $analyzerManager->analyze($url)->getAnalysis();

$data = [];

foreach ($analysisCollection as $analyzer => $analysis) {
    $data[$analyzer] = $analysis->getData();
}
