1.2.252. Could Be Callable¶
Mark arguments and return types that can be set to
callable.
The analysis also reports properties that could be ‘callable’, although PHP doesn’t allow that configuration. Note that properties cannot be callable. It reports a compilation error.
<?php
// Accept a callable as input
function foo($b) {
// Returns value as return
return $b();
}
?>
See also Callbacks / callables.
