What are the potential challenges of integrating PHP code within a Perl script?

One potential challenge of integrating PHP code within a Perl script is the different syntax and functionality between the two languages. To solve this, you can use the Perl `system()` function to execute the PHP code as a separate process. This way, you can effectively run PHP code within a Perl script without worrying about compatibility issues. ```perl # Execute PHP code within a Perl script using the system() function my $php_code = <<'END_PHP'; <?php // Your PHP code here echo "Hello from PHP!"; ?> END_PHP my $output = `php -r '$php_code'`; print $output; ```
