php - 尝试让 php 使用完整的 url 而不是相对路径输出 xml

Question

我在浏览器中工作正常，但 iOS 版的 Air 需要完整的地址。

<?php $path_to_image_dir = 'Games/game_images/'.$username; 

    $xml_string = "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?><data> <LoaderMax name=\"gallery\">";

    if ( $handle = opendir( $path_to_image_dir ) ) {
        $i = 1;
        while (false !== ($file = readdir($handle))) {
            if ( is_file($path_to_image_dir.'/'.$file) ) {
                $xml_string .= "<ImageLoader url=\"" . $path_to_image_dir."/".$file . "\"  />";
            }
        }
        closedir($handle);
    }


$xml_string .= "</LoaderMax></data>";
$ignore = array('.','..','cgi-bin','.DS_Store');
$file = fopen($username.'_imagesfile.xml','w');
fwrite($file, $xml_string);
fclose($file);
?>

这是 xml 结果:

<?xml version="1.0" encoding="iso-8859-1"?><data> <LoaderMax name="gallery"><ImageLoader url="Games/game_images/mrpeepers/1365535674.jpg"  /><ImageLoader url="Games/game_images/mrpeepers/1365535527.jpg"  /></LoaderMax></data>

如果手动添加地址，则适用于 ios http://wwww.mysite.ccom/Games/game_images/mrpeeper/1365535674.jpg

将 $_SERVER['SERVER_NAME'] 添加到您的目录名称中，如下所示:

$xml_string .= "<ImageLoader url=\"" . $_SERVER['SERVER_NAME'] . "/" . $path_to_image_dir."/".$file . "\"  />";
