Ouput stuff while php script is running

So I just created a script to resize a whole bunch of images. Is there anyway to have there be output as its running through the loop?

Basically I have like 400 photos in photo db table. Its gathering a list of all these photos, then looping through each one and resizing it 3 times. (large,medium,small version).

Right now on each loop I am echoing that images results, but I dont see the results untill EVERYTHING is done. So like 10 minutes later, I will get output. I added this set_time_limit(0); to make sure it 开发者_开发问答doesnt time out.

**EDIT ** It looks like every so often the script actually updates to the browser, maybe every 30 seconds?

You can use flush() or ob_flush() to tell the script to send something back to the client after you do an echo().

BUT - you never really have complete control over it, the web server does, so the web server may not cooperate depending on how its configured. For example, if you have the server doing gzip rather than using PHP's gzip features, the web server may still buffer the output.
