php相对路径转化成绝对路径

提取 Gregarius中的一个函数。可以把网页中的相对路径自动转化成绝对路径。

<? function relative_to_absolute($content, $feed_url) { preg_match('/(http|https|ftp):///', $feed_url, $protocol); $server_url = preg_replace('/(http|https|ftp|news):///', '', $feed_url); $server_url = preg_replace('//.*/', '', $server_url);

if ($server_url == '') { return $content; }

if (isset($protocol[0])) { $new_content = preg_replace('/href='https://', 'href='https://www.haobala.com/bcjs/21976.html'.$protocol[0].$server_url.'/', $content); $new_content = preg_replace('/src='https://', 'src='https://www.haobala.com/bcjs/21976.html'.$protocol[0].$server_url.'/', $new_content); } else { $new_content = $content; } return $new_content; } ?>
