执行PHP CGI脚本作为后台进程？

Can I run a PHP CGI script as a background process using exec() ?

You could try it to start it as an linux background process using exec().

You could try this:

exec('/usr/bin/php /path/to/your/script.php &');

The '&' tell's linux to start this command in the background.

Note: You lose control over your executed script at that point and it may not work with all hosts (especially shared host envoirements).
