首次入场

我编写了一个脚本，用于根据表格中输入的数据生成rss Feed。我想从表中的字段生成文件名，我创建如下：

$path = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
$feedtitle = str_replace(" ", "", $feedtitle);
$feedtitle = str_replace("_", "", $feedtitle);
$feedtitle = str_replace("-", "", $feedtitle);
$feedtitle = strtolower($feedtitle);
$path = substr($path, 0, strrpos($path, "/"));
$feedlink = "$feedtitle" . '.xml';

因此，如果$ feedtitle是Last Nights Television，$ feedlink的值将是

lastnightstelevision.xml

我通过指定文件名测试了脚本并且它可以工作，从表中提取数据并创建一个feed。这是脚本的最后一部分：

$rss = createXML($items,$initdata);
$filename = 'myfeed.xml';
file_put_contents($filename,$rss);
header("Location: uploadcontent.php?message=".urlencode("Show saved and feed updated"));
?>

在我的服务器上创建了一个名称myfeed.xml。

但是我希望Feed的文件名是$ feedlink的值。我知道这可能是基本的，但我无法弄清楚如何去做。

我试过了：

$filename = ".$feedlink";
$filename = ".$feedlink[feedlink]";

以及许多其他组合。

如果您尝试从RSS获取该文件名，请尝试使用

$attribute = $rss->channel->children("atom", true)->link->attributes();
$filename = $attribute["href"];

或者，如果您想从第一个查询返回的结果中获取

$filename = $initdata['feedlink'];

上面的结果是一个完整的路径，因此如果您只需要该路径中的文件名，请使用此

$feedlink = "http://mywbsite/mydir/lastnightstelevision.xml";
$filename = basename($feedlink);

输出：

lastnightstelevision.xml
