[SOLVED] Renaming a File EXTENSION

[Warptweet]

Heres a bit different of a problem I have now...

How can I rename a file EXTENSION??? Can somebody help?
I think it has to do with...

[code]<?php
rename("XXX","XXX")
?>[/code]

Except I don't know what the stuff inside the ""'s do.
Can somebody explain to me how I would not rename a file, but change it from a .swf file to a .txt file, while keeping the same name besides the extension change?
And after that, I need to write these variables...

$flashname = $_POST['flashname']
$flashauthor = $_POST['flashauthor']
$flashdescription = $_POST['flashdescription']

I think I know how to write those variables myself though. I mainly need help with the extension changing, thanks!

Extensions are just part of the filename:

[code]<?php
rename('file.oldextension', 'file.newextension');
?>[/code]

So you ARE in fact renaming the file.

Could you tell me how I would change the extension of the file called $ourFileName, and then change $ourFileName to .txt?

Change file with any extension to .txt:

[code]<?php
rename($fileName, substr($fileName, 0, strrpos($fileName,'.')).'.txt');
?>[/code]

Thanks.
I have one more question....

When I write to a file, can I use a variable this way?

[code]$stringData = "$flashname";
    fwrite($fh, $stringData);[/code]

As you can see, I used $stringData = "$flashname";, is that possible to use? Or will I get an error? If I can't how can I make $stringData = $flashname?

Remove the quotes around $flashname. Quotes are used on strings, not variables.
