Here is a new attempt, but I still don't see the Please Wait page, instead
it goes straight to the show_result.php
//*********** the form processing.php code************
// long exec (asynchronous - it exits immediately but continues processing),
its end will tested in the next script
exec( ... );
header( "Location: please_wait.php" );
echo( "\nPlease wait" );
flush;
exit;
*********** end of form processing
//********** the "please wait.php" code *************
while( long_operation_not_done )
usleep( 100000 ); // check the operation each 0.1 secs
header( "Location: show_result.php" );
exit;
//************ end code *****************
If I put the echo in second php script, I get an error about headers already
sent or similiar.
I don't know php well enough to figure out a solution to unblock me at this
point, so any new idea would be highly appreciated.
