Note Submitter: camusatan at yahoo dot com ---- I tried forever to figure out how to invoke a background process, _then_ get its PID so that I can later check on it. On Linux (with /bin/sh equalling /bin/bash), the following finally worked: $shell_results= exec("wget -O - \"$myurl\" &>/dev/null & echo \$!", $results,$status); The command I'm invoking is 'wget', and $shell_results will end up with the PID of the background wget process. The $results and $status variables I mostly just used for troubleshooting and getting this line working. I put a backslash in front of the dollar sign to keep PHP from trying to interpret it as a variable.
