How can output buffering and include functions be utilized effectively when working with Perl scripts in PHP for graphical output?

When working with Perl scripts in PHP for graphical output, output buffering can be utilized to capture the output of the Perl script and include functions can be used to insert this output into the PHP script. This allows for seamless integration of Perl scripts within PHP code, making it easier to manage and manipulate the output.

<?php
ob_start();
include 'perl_script.pl';
$output = ob_get_clean();

// Manipulate the output as needed
echo $output;
?>
