How can PHP interact with Perl scripts and pass parameters without using cookies?

To pass parameters from PHP to Perl scripts without using cookies, you can utilize the command line interface to execute the Perl script with the necessary parameters. This can be achieved by using the `exec()` function in PHP to call the Perl script and pass the parameters as command line arguments.

$param1 = "value1";
$param2 = "value2";

// Call Perl script with parameters
exec("perl script.pl $param1 $param2");
