What are the best practices for running Perl scripts as background processes without browser interaction in PHP?

When running Perl scripts as background processes without browser interaction in PHP, it is best to use the `exec()` function to execute the Perl script in the background. This allows the PHP script to continue running without waiting for the Perl script to finish. Additionally, using `nohup` and `&` at the end of the command ensures that the Perl script continues running even after the PHP script has finished executing.

$perlScript = "/path/to/perl/script.pl";
$command = "nohup perl $perlScript > /dev/null 2>&1 &";
exec($command);
