Show Loading image while data gets loaded

[apoorv....@gmail.com]

Hello I am using a web service to fetch some data from another server I am running and based on the result I get I run foreach loop and show results.

Now I am using file_get_contents to fetch data Now It takes good 3-4 seconds for data to get loaded and the page seems to be loading.

I want to show a loading gif or a message that please wait and when I get result I want to show that.

I know we cab do that when we submit a form with beforesend function or show hide a gif but how would I do that with file_get_contents.

I'm not sure I understand the problem: you could place/echo some HTML before
executing the file_get_contents command, and that HTML should be displayed
on the clients webbrowser (it will display as much as it can, even when it
hasn't encountered the "</BODY>" and or "</HTML>" tags yet).

<?php
echo "<h3>Loading data, please wait</h3>";

$contents = file_get_contents(....);

echo "<h3>Finished loading, now processing data</h3>";

// do something with $contents here

?>

(untested, but should work)

Hope that helps.

Rudy, what you are suggesting works in most browsers. But beware that
it is browser dependent (including browser version) and won't
necessarily work in all cases. It's also dependent on the HTML being
sent; i.e. a <table> without the matching </table> seems to fail to
display more than non <table> data.

But it varies widely.

Alas, that (small differences) is always a problem with browsers. :-\

Thats something I've seen too.

But agreed, its something the OP should be aware of.
