Original question on StackOverflow: https://stackoverflow.com/q/28343884/2324078


I saw the list-intrinsic specification (https://github.com/php/php-langspec/blob/master/spec/10-expressions.md#list), which states that for a list-intrinsic construct, the right-hand side of the simple-assignment-expression must be an expression that designates an array.

But the documentation of list from php.net (http://php.net/manual/en/function.list.php), gives an example like the one in the attached test script of this ticket.

The thing is that PDOStatement::fetch(PDO::FETCH_NUM) returns FALSE if there is no further row. But the right-hand side of the assignment-expression must be an array - and FALSE is not an array. So this would result in a fatal-error, right?

Have I missed something, or is this really an inconsistency?

Test script:
---------------
$result = $pdo->query("SELECT id, name, salary FROM employees");
while (list($id, $name, $salary) = $result->fetch(PDO::FETCH_NUM)) {
    //output $id, $name and $salary
}
