我希望能够获得189.99美元。PHP HTML DOM解析

echo $ret[0]->find('tr', 4)->plaintext;

此输出： '价格：$ 189.99'

我只需要$ 189.99，而不是 '价格：'

什么'vardump（$沤[0] - >查找（” tr'，4））'给你？ – powtac 2009-11-23 17:45:17

致命错误：调用未定义的函数vardump（）在C：\ xampp \ htdocs \ ... – manny 2009-11-23 17:47:24

var_dump（）是他的意思 – 2009-11-23 17:48:34

$exp = explode(":", $ret[0]->find('tr', 4)->plaintext); 
$price =$exp[1];
