1、首先要在程序的開始引入simple_html_dom.php這個文件
參考代碼:include_once('simple_html_dom.php');
2、PHP Simple HTML DOM Parser提供了3種方式來創建DOM對象
參考代碼如下:
// Create a DOM object from a string
$html = str_get_html('<html><body>Hello!</body></html>');
// Create a DOM object from a URL
$html = file_get_html('');
// Create a DOM object from a HTML file
$html = file_get_html('test.htm');
得到DOM對象後就可以進行各種操作了
// Find all anchors, returns a array of element objects
$ret = $html->find('a');
// Find (N)th anchor, returns element object or null if not found (zero based)
$ret = $html->find('a', 0);
// Find lastest anchor, returns element object or null if not found (zero based)
$ret = $html->find('a', -1);
// Find all <div> with the id attribute
$ret = $html->find('div[id]');
// Find all <div> which attribute id=foo
$ret = $html->find('div[id=foo]');
