php把相对路径转换成绝对路径方法
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 ;
}
//取得所有链接
function get_all_url( $code ){
preg_match_all( '/<as+href=["|' ]?([^>" ' ]+)["|' ]?s*[^>]*>([^>]+)</a>/i', $code , $arr );
return array ( 'name' => $arr [2], 'url' => $arr [1]);
}
