Label ‘%s’ already defined¶
Description¶
A goto label has been defined twice or more. This is not allowed, as the goto
call won’t be able to decide which label to reach.
Note that a single unused label is allowed, and is considered dead code.
Multiple identical labels are possible, in different method contexts.
Example¶
<?php
function foo() {
C:
C:
// valid code, though dead and unused
D:
}
function bar() {
// valid code, though dead and unused
D:
}
?>
