php - output echo'd contents in browser while script is running?

Question

Does anyone know how to output stuff I echo to a browser while the script is running?

I have a long loop that I'd like to output a string after every run of the loop, kind of like a progress bar, does anyone know how to do that?

Use the ob_flush() function:

ob_start();
//echo stuff...

ob_flush();

//echo more stuff...

ob_flush();

I tried that and unfortunately it didn't do anything, script still executes fully then outputs everything at once to browser.

@Joe, It is probably working fine, but your browser probably isn't displaying it to you. Check it with a packet sniffer, or Fiddler or similar. Also, some servers won't push that data to you when ob_flush() is called. It is up to the server, not PHP, to do this.
