Summary of usage based on simple_html_dom_PHP tutorial
简单范例
$html = file_get_html('http://www.google.com/'); //获取html$dom = new simple_html_dom(); //new simple_html_dom对象$dom->load($html) //加载html// Find all images foreach($dom->find('img') as $element) { //获取img标签数组 echo $element->src . '
'; //获取每个img标签中的src}// Find all links foreach($dom->find('a') as $element){ //获取a标签的数组 echo $element->href . '
'; //获取每个a标签中的href}
$html = file_get_html('http://slashdot.org/'); //获取html$dom = new simple_html_dom(); //new simple_html_dom对象$dom->load($html); //加载html// Find all article blocksforeach($dom->find('div.article') as $article) { $item['title'] = $article->find('div.title', 0)->plaintext; //plaintext 获取纯文本 $item['intro'] = $article->find('div.intro', 0)->plaintext; $item['details'] = $article->find('div.details', 0)->plaintext; $articles[] = $item;}print_r($articles);
}
// Create DOM from string
$html = str_get_html('
$dom = new simple_html_dom(); //new simple_html_dom对象
$dom->load($html); //加载html
$dom->find('div', 1)->class = 'bar'; //class = 赋值 给第二个div的class赋值
$dom->find('div[id=hello]', 0)->innertext = 'foo'; //innertext内部文本
echo $dom;
// Output:
