將加載文本添加到此腳本？

Question

我正在使用Interspire link.php功能，並希望添加文本只是說該頁面正在加載看，因爲它需要2-5秒來完全加載腳本。

我在哪裏添加它？

header('Location: ' . $url); 

我試過在各個地方加入echo "Hello world!";，都沒有工作。

我不知道這個代碼是如何被調用，但你可以嘗試註釋以下行：

header('Location: ' . $url); 

，取而代之的是：如果它仍然重定向像它應該

echo "<script>window.location.replace('".json_encode($url)."')</script>"; 

，你可以嘗試在開始時添加你的文本。
