note 107456 added to function.exec

As already noted by others, to background a single command on Linux append the & symbol. For a sequence of commands, enclose them within parentheses then append the & symbol but be sure to redirect stdout, stderr somewhere otherwise your script will hang waiting e.g.: <?php exec('( sleep 10; echo "finished" | mail ian@example.com ) &> /dev/null &'); ?> Usually you would put the commands in a shell script and call that from exec, however the above trick will help where the sequence is dynamically generated from php.
