partial display and exec output

[bfdi533]

I have a script that is being called from shell_exec and it runs for about 15 seconds.

I need to display the first part of the web screen and give a message like "this will run for 15 seconds, please be patient until it completes." I have tried to put this into the HTML before my PHP code but it does not display in the browser until the shell_exec completes.

How can I get the HTML to display and then run the shell_exec and then display its results?

The webserver is probably buffering the output. You could force some whitespace chars down to make it flush the buffer.

print str_repeat(" ",8192);

You can try using the flush() command and/or output buffering, but PHP really wasn't designed with this type of functionality in mind.

Thanks for the tips. I ended up doing the following, which works great:

echo str_repeat(" ", 300);
flush();


Thanks again.
