Long time to finish a program

[rahulthathoo]

Hi

I have a perl program called by my php script, which in turn is called
by the browser. Now, the perl program is called using exec, but takes
a long time to finish. So, till the time the perl script does not
finish its job, the browser does not show anything. I have messages
like "Dont close this window", but that does not show up till the
whole perl program finishes. Is there a way, I can somehow remedy
this, try to show a message on the browser - "Please while your data
processes" and then do the processing in the background?

Rahul,

You need to flush() your output. But beware - just because it goes to
the browser doesn't mean the browser will display it. For instance, if
it's in a table, the browser may wait for the entire table to be sent.
And there are a lot of other possibilities.

But if you keep it short and clean, you have a better chance to get your
message displayed immediately.
