Basic question really, I know I can do this in some other languages but I dont know PHP that well, hoping someone can help.
So I have the following.
$holyToT *=100;
$coldToT *=100;
$fireToT *=100;
$poisonToT *=100;
$lightningToT *=100;
And I want to be able to just condense it down to something like:
$holyToT, $coldToT, $fireToT, $poisonToT, $lightningToT *= 100;
Does PHP have an internal way of doing something similar?
I agree with the others, but if you really want to have it in one line, you could do something like this:
list($holyToT, $coldToT, $fireToT, $poisonToT, $lightningToT) = array_map(function($x) { return $x*100;}, array($holyToT, $coldToT, $fireToT, $poisonToT, $lightningToT));
There is no syntax that allows you to do exactly this in a single statement.
You could cook up ways of doing this (by pushing everything inside an array), but the result would be much less clear and performant than a group of assignments.
Something like this comes to mind, but if they catch you doing this don't say you heard it from me:
extract(array_map(
function($i) { return $i * 100; },
compact('holyToT', 'coldToT', 'fireToT' /*, ... */ )
));
There is ni build in functionality. Depending on the PHP Version you could pass an array and a lambda function to a custom function.
function performOnAll(array $a, $fct) {
foreach($a as $v) $fct(&$a);
}
performOnAll(array($a, $b, ...), function(&$a) { $a *= 100; });
That's it basically (not syntax checked).
