You may want to know that removing semicolon is optional sometime but need to know the condition when it can be removed and when it can't be.

// Example 1: PHP script with closing tag at the end.
<?php

// php code

// you can remove semicolon
mysqli_close( $db )
?>

// Example 2: PHP script without closing tag at the end.
<?php

// php code 

// you can't remove semicolon
mysqli_close( $db )
