我们经常会碰到采集内容时,要补全地址是吧,下面我们来看看这款php把相对路径转换成绝对路径方法吧,相对路径转化成绝对路径实例代码如下:
- function relative_to_absolute($content, $feed_url) {
- preg_match('/(http|https教程|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])) {
- $new_content = preg_replace('/href="//', 'href="'.$protocol[0].$server_url.'/', $content);
- $new_content = preg_replace('/src="//', 'src="'.$protocol[0].$server_url.'/', $new_content);
- } else {
- $new_content = $content;
- }
- return $new_content;
- }
-
- function get_all_url($code){
- preg_match_all('/<as+href=["|']?([^>"' ]+)["|']?s*[^>]*>([^>]+)</a>/i',$code,$arr);
- return array('name'=>$arr[2],'url'=>$arr[1]);
- }
