Question

可从中提取<代码><<<<>>>>/代码>的内容。网页从<one> and end with </one> in php。如果有的话,任何人都可以找到某些样本。

Answer 1

You should have a look at the DOMDocument reference.

该实例是一份html文件,创建了,并贴上了标签:

libxml_use_internal_errors(true);
$dom = new DOMDocument;
$dom->loadHTMLFile( http://example.com );
libxml_use_internal_errors(false);

$body = $dom->getElementsByTagName( body )->item(0);

echo $body->textContent; // print all the text content in the body

你们还应检查以下资源:

DOM API Documentation
XPATH language specification

Answer 2

Try

$html = file_get_html( http://www.example.com/ );
$body = $html->find( body );

Answer 3

You can also try to use non-DOM solution based on strpos function:

$html = file_get_contents($url);
$html = substr($html,stripos($html, <body> )+6);
$html = substr($html,0,strripos($html, </body> ));

stripos is case insensitive version of strpos, strripos is case insensitive rightmost position version of strpos.

希望这将有助于你们!
