1.2.1015. Raised Access Level

A visibility may be lowered, but not raised. Visibilities apply to properties, methods and class constants.

This error may be detected by PHP when the classes are in the same file, and declared in the right order : then, PHP reports a compilation error. However, when the classes are separated in different files, as it is customary, PHP won’t check this at linting time, yielding a fatal error at execution time.

<?php

class Foo {
    public $publicProperty;
    protected $protectedProperty;
    private $privateProperty;
}

class Bar extends Foo {
    private $publicProperty;
    private $protectedProperty;
    private $privateProperty;   // This one is OK
}
?>
