I'm having someone develop a site for me and they said it is not possible to have a progress bar with PHP. Is that true??? He said he could write it in another language but it would be less secure.

Its a site that is using Joomla! and people login to upload files...when they click upload I want there to be a progess bar so people can see the file is actually uploading and not hung up. I want it to check to see if the file is the same exact file on the computer as the server.

I really want a progress bar because I upload very large files...is a progress bar possible in PHP and is there somewhere I can point my developer to?

You can look at this from PHP.NET, but apperently it requires PHP 5.2 or newer.

EDIT: I'm not sure if you're required to use a new window for the progress bar, or if you can just get away with an <iframe>. It's not really something I've looked into, and it'd largely depend on the browser used. If it worked, you'd at least know your progress bar wouldn't be blocked.

I'm not a PHP scripter, but doesn't PHP have a progress bar class? Could that be used?

I Googled it and found this

"Computer security." — Oxymoron

hmm, well you could design a progress gif at http://www.ajaxload.info/ and call this gif in the php code in the upload part of the code. Or use some Ajax to produce the gif when uploading.
