Are there specific tools or extensions available for integrating Perl scripts into PHP applications?

There are no specific tools or extensions available for directly integrating Perl scripts into PHP applications. However, one way to achieve this integration is by using PHP's `exec()` function to execute Perl scripts from within a PHP script. This allows you to run Perl code and capture its output for further processing within your PHP application.

$output = exec('perl script.pl');
echo $output;
