What are the common pitfalls or errors that may occur when trying to include and execute a CGI script within a PHP environment?

One common pitfall when trying to include and execute a CGI script within a PHP environment is not setting the correct permissions for the CGI script file. Make sure the file has executable permissions in order for PHP to be able to run it. Additionally, ensure that the file path is correct and properly specified in the PHP script. 

<?php
// Set the correct permissions for the CGI script file
chmod('/path/to/cgi/script.cgi', 0755);

// Specify the correct file path for the CGI script
$script_path = '/path/to/cgi/script.cgi';

// Execute the CGI script within PHP
$output = shell_exec($script_path);
echo $output;
?>
