I did a very basic test: <?php set_time_limit (1); print exec ('for file in ls -R /; do echo $file; done'); for ($x=0; $x < 1000000; ++$x) ; echo "Foo!"; ?> The script runs, exiting with this message: /var/yp/binding Fatal error: Maximum execution time of 1 second exceeded in /home/zak/public_html/stl.php on line 6 It looks like the time limit does not apply to the executed program... --zak > > Zeev > > At 07:17 15/1/2001, Zak Greant wrote: > >A recent note added to the manual errata pointed out the > >set_time_limit does not affect system commands that have > >been executed by PHP. > > > >I would guess that attempting to limit system behavior in > >this way is beyond the scope of set_time_limit. > > > >Any opinions or options on this issue?
