Re: Scope of set_time_limit

Right - as I said, the executed program will go on running, whereas the script will terminate... At 01:44 16/1/2001, Zak Greant wrote:

    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...

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? My feeling is that we document that set_time_limit is not a safe way to limit the resource usage of commands run via calls to exec, etc... --zak -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: php-dev-unsubscribe@lists.php.net For additional commands, e-mail: php-dev-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
