I never understood why people use the "switch" statement just to "break" at the end of each code block - see many implementations of Drupal's hook_block() or hook_nodeapi() which switch on $op. If you're not going to be making use of the fallthrough functionality switch allows, why not just use the "if/elseif" statements and avoid switch's stupid syntax?

with all these breaks the switch is sadly even more verbose than if/elseif blocks. Not to mention bugs if you forget breaks.
ideally switch should something be like,

Switches are easier to type
Switches are easier to type and read, and get optimized to jumptables in most language

$op will getting killed for the next version of drupal.
why switch?
because it is less verbose than if/elseif :-)
Re: I never understood why people
I never understood why people use lots of if/elseif blocks to test the value of the same variable in each block ;-)
Bingo!

with all these breaks the switch is sadly even more verbose than if/elseif blocks. Not to mention bugs if you forget breaks.
ideally switch should something be like,
switch ($foo) {
1: {
print 1;
},
2: {
print 2;
},
}
looks like hash, doesn't it?
with new closures that would be
$switch = array(
1 => function () {
print 1;
},
2 => function () {
print 2;
},
);
$switch[$i]->(); # or something like that
Anyone else use this idiom ?
<?phpswitch(true) {
$a === $b =>
echo 'a === b';
break;
$a == $b =>
echo 'a == b';
break;
$a < $b =>
echo 'a < b';
break;
$a > $b =>
echo 'a > b';
break;
}
?>
