What are the potential consequences of not including an exit; statement after an echo command in PHP?

If an exit statement is not included after an echo command in PHP, the script will continue executing the remaining code which may lead to unexpected results or errors. To prevent this, always include an exit statement after an echo command to ensure that the script stops executing at that point. 

echo "Hello, World!";
exit;
