PHP 4.0 Bug #7607 Updated: system()ed commands do not exit if the user interrupts transfer

ID: 7607 Updated by: stas Reported By: doktor1@earthlink.net Status: Closed Bug Type: Program Execution Assigned To: Comments: PHP cannot do this. Since PHP has no way to know which processes are launched with your system command, and the Apache process does not stop - so system won't terminate executed process - you should take care on this by yourself. See for example proposal from Jean-Michel Dault <jmdault@mandrakesoft.com>: This is an Apache issue. This bug is not present in the standalone version. Even if you press stop, the apache process is trill running. Solution: system("/path/to/ping -w SECS somehost") to have it die after SECS seconds But then, if you press stop, you'll still have zombie processes... So you should try this: echo "ping -w 30 \$1" > /tmp/ping;chmod 0755 /tmp/ping ... and have <?php system("/tmp/ping $host"); ?> instead If fixes the problem. Previous Comments: --------------------------------------------------------------------------- [2000-11-02 20:21:29] doktor1@earthlink.net If I system("/path/to/ping somehost") and then hit Stop or close the browser or go to a different page, the ping process will still be in the process table, and show as being owned (PPID) by httpd. I don't know whether this is an issue with php or with Apache. --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=7607
