What command can be used to load xterm along with the program when using exec() in PHP?

When using the exec() function in PHP to run a program like xterm, you can use the command "xterm -e" followed by the program you want to run. This will load xterm along with the program, allowing you to interact with the program through the xterm terminal window.

<?php
$program = "your_program_here";
exec("xterm -e $program");
?>
