This is a manifestly a leftover of an old syntax. Take a look at the PHP/FI 2 manual: Language constructs: https://www.php.net/manual/phpfi2.php#lang <https://www.php.net/manual/phpfi2.php#lang> ``` <? if($a==5 && $b!=0 ); $c = 100 + $a / $b; endif; > ``` and, in particular, switch construct: https://www.php.net/manual/phpfi2.php#switch <https://www.php.net/manual/phpfi2.php#switch> ``` <? $a=0; switch($a) { case 1; echo "a is 1"; break; case "hello"; echo "a is hello"; break; default; echo "a is unknown"; break; } > ``` Note that every line of code, including `if (...);` and `case...;`, is consistently terminated by a semicolon. In a subsequent major version, the syntax was modified, and you would use a colon instead of a semicolon in a number of places, as you can write today: ``` <?php if ($a==5 && $b!=0): $c = 100 + $a / $b; endif; > ``` Although the old `if (true);` syntax has been removed (probably because of ambiguity or difficulty of parsing), the old `case 1;` syntax could be left without issue. —Claude
