How can PHP interact with Perl scripts to execute specific functions and pass values between the two languages?

To interact with Perl scripts in PHP, you can use the `exec()` function to execute specific Perl functions and pass values between the two languages. You can pass arguments to the Perl script using command-line arguments or by writing to the standard input of the Perl process. The output of the Perl script can be captured and processed within the PHP script.

// Execute a Perl script with arguments
$arg1 = "value1";
$arg2 = "value2";
$output = exec("perl script.pl $arg1 $arg2");

// Process the output from the Perl script
echo $output;
