Progress bar for long running scripts

[renobird]

I need to create a progress bar for a long executing csv export.

I know how to do all the front end stuff, but I'm encountering some issue with polling the progress, and need some assistance.

The hosting environment is preventing me from using the the flush(), ob_flush() process, not sure why.

I have an older script that used to work well, but it doesn't now. It might have something to do with apache settings, but I can't track it down.

I've been attempting to write the progress to a $_SESSION variable, but I can't seem to get around session locking, so when I try to check the $_SESSION variable via ajax, I get nothing because the script has the session locked until it's done. 

I can't use web sockets because I need support IE9.

I haven't tried writing the progress to a temp file.

What are some other options? 

Suggestions welcome.

Doh!

Somewhere in the back of my mind, I remembered solving this issue with session locking before.

session_write_close() is what I needed.

I'll post back here with a full solution to keep the topic relevant.

Hello,

I'm facing this issue at the moment... A PHP script that seems to take too long and the browser returns a timeout. Flushing works fine on my localhost but doesn't on remote

I have no idea what I can do, so if @renobird or anybody else has some advice, I would appreciate

Thanks !
