wait for result from exec

[Gunnar G]

If I wish to run an external application with exec(), does the execution of
the PHP script halt until the external application has finished?

Hi,

Did you check the documentation?

http://nl2.php.net/manual/en/function.exec.php

Look at the notes:
Note: If you start a program using this function and want to leave it
running in the background, you have to make sure that the output of that
program is redirected to a file or some other output stream or else PHP
will hang until the execution of the program ends.
