Thanks guys for your response. I think this output from reply can solve my
problem. Becuase I can return some value like ' fileready == true' as the
output from the executable program. And when fileready is true I can read
the output text file. Can you please explain a little bit what kind of
output shell_exec will retrieve. I mean how can i define a boolean variable
like fileready and have it returned to php as output so that I know that
text file is ready to be read.
Thanks
