前言
DOM是php比较新的xml和html处理类,可以像javascript那样方便的操作DOM树,网上更多的是介绍它处理XML的情况,今天这篇文章就介绍下php解决DOM乱码的方法,下面话不多说,直接看下面的解决方法。
解决方法如下
/** * 请求url页面信息 * @param str $url * @return str mixed|boolean */ function curl_get($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //302跳转 curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0'); curl_setopt($curl, CURLOPT_REFERER, $url); $data = curl_exec($curl); $code = curl_getinfo($curl,CURLINFO_HTTP_CODE); //输出请求状态码 curl_close($curl); if(200 == $code) { //解决乱码 if (preg_match('#<meta[^>]*charset="?gb2312"[^>]*>#', $data)) { $data = iconv("gb2312","utf-8//IGNORE",$data); $data = preg_replace('#<meta[^>]*charset="?gb2312"[^>]*>#is', '<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">', $data); } if (!preg_match('#<meta charset="utf-8"[^>]*>#is', $data)) { $data = str_replace('<head>', '<head><meta http-equiv="Content-Type" content="text/html;charset=UTF-8">', $data); } if (preg_match('#<meta charset="utf-8"[^>]*>#is', $data)) { $data = preg_replace('#<meta charset="utf-8"[^>]*>#is', '<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">', $data); } return $data; } else { return false; } }
/** * 获取 DOMDocument 对象 * @param str $url * @return boolean|DOM */ function getDom($url) { $html_content = curl_get($url); if(empty($html_content)) { //saveLog($url, '请求失败'); return false; } $dom = new DOMDocument('1.0', 'utf-8'); libxml_use_internal_errors(true); $dom->loadHTML($html_content); return $dom; }
$html_content = mb_convert_encoding($html_content, 'UTF-8', 'gb2312');
