It's very simple. Create the shell script kill4d.sh:
#!/bin/bash
KILLSIGNAL=/path/to/writeable/directory/killsignal
while true
do
if [[ -f "$KILLSIGNAL" ]]; then
rm -f "$KILLSIGNAL"
killall 4D
fi
sleep 1
done
Change KILLSIGNAL to point to a path within a directory that is writeable by
PHP. You may have to chmod a directory within PHP's web root to allow this.
Then do:
chmod +x kill4d.sh
The run it as whatever user launches 4D. All your PHP script has to do is:
shell_exec('touch /path/to/writeable/directory/killsignal');
That should do it.
