how to display please wait message and redraw

This may fall under html but I'll ask it here anyway.  I have a rather large search taking place through php that takes about 20 seconds to complete.  What would be great is if there is a way for our banners to be displayed with a message below them saying this will take a few moments and then to have that message replaced by the results of the search.  Can this be done?  If so how?  It doesn't have to code, just show me the path with the bread crums :-)

Heres my answer as requested....

If your looking to learn javascript quickly check out under the javascript manuals.. It is an extremely good site with heaps of useful examples...

I use on a daily basis as it contains the entire DOM ( Document object Model ).

Thanks Again

hmm I think you can't do that with PHP.
Javascript(dhtml) is only the good solution for your problem.
I may wrong but  php is a server-side language, it returns
to your browser only "static page".
yes, i think it can be done by PHP
but i don't know how to either
so, let's wait for experts!

I think the problem with this is that you need PHP to be able to determine when your search has finished.

Here's an idea ...

Create two php files

One retreives the web search page from the server and then sets an marker file using a unique session id.

The other displays a message and waits for the existance of the marker file for a specified time limit and then redirects the use to this page...

Expanding on this...

Page One...

1. Gets the parameters from the search
2. Creates a Unique ID
3. Starts the search using the Paramters using the file('http://server/search?SearchString') function
4. Gets all of the data from file() and writes it to a <session>.html file
5. Redirects the user to the second page
6. When all the data has been read from the file() Function and output
creates <session>.finished file

Page two

1. Checks for the existance of the <session>.finshed file
2. If it exists then redirect the use to it
3. If it doesn't exist refreshes the current page after 2 seconds
4. If a specified number of refreshes has been reached and the .finished file doesn't exist then display a time-out message.

For redirection you can use the function

print ("<HEAD><META HTTP-EQUIV=Refresh CONTENT=2;URL=/Server/page.php3?$SessionID></HEAD>");

Might work ??? You will need to run something to clean up the temp files though... There might be a prettier way though ??

I think Samon give you a idea. don't he ?
But i think you better do this by using Javascript 'cause it's quite easier. You may do it as same as window style. The reason is as same as us111 'cause PHP is a sever-side script.

Simon's comment could be a solution but more easier with javascript.
hmm, what's happened when you leave your page and redirect to page two ?
Is the session file already written ? hmm, if you run a script in background, yes otherwise I don't think so.

What's happened if my connection is really bad ??

As for me, the best solution is Javascript
I agree with everyone here, javascript is a much better solution for this ..  Something like have two <div> one visible with the message and the other that contains all of the data that becomes visible only after  the document is finshed loading ( document.all)...

But this is the PHP section so I at least thought I would give a PHP solution a go .... You may have noticed I only said it might work !!!

Thanks for all your comments.  From what I am reading I guess I need to add javascript to my resume by learning it.  

Simon Henry if you could just give an answer, I would like to give you some points because you did come up with an idea that would work but it might be easier for me to learn javascript then to use your idea.

I am going to be posting this question under javascript since this needs to have been done last week and my first day on the job was yesterday :-/
But if you would like to use IE. or crosss brower you better go here

hope my comment would help you some

In my opinion, Dynamic Duo ( is the most powerful library for DHTML.
