Is there a short-circuit OR in PHP that returns the left-most value?

Question

In some languages, you can do

$a = $b OR $c OR die(\"no value\");

That is, the OR will short-circuit, only evaluating values from left to right

Answer 1

You could use some kind of coalesce function:

function coalesce() {
    foreach (func_get_args() as $arg) {
        if ($arg) {
            return $arg;
        }
    }
    return null;
}

$a = coalesce($a, $b) or die("no value");
