1.2.250. Could Be Array Typehint

This rule spots arguments, class constants, properties or return values that may be labeled with the array scalar typehint.

<?php

// $arg is used as an array in this function, so it may be typed : array
functions foo($arg) {

    // the returned value is always an array, so this function might be typed as : array
    return array($arg[3]);
}

?>
