不能在PHP类上使用public修饰符

I have very strong basic in Java, and when comes to PHP I got some problem with the OOP.

Please take a look at this two classes below:

Contacts.php

<?php 

    public class Contacts {

    }
?>

UnitTest.php

<?php

    require_once 'PHPUnit/Framework.php';
    include 'Contacts.php';

    class UnitTest extends PHPUnit_Framework_TestCase {

        public function testRead() {
            $temp = new Contacts();
        }
    }
?>

When I trying to test the UnitTest.php using phpunit I got this error message:

PHP Parse error:  syntax error, unexpected T_PUBLIC in
    /home/crazenezz/Projects/PHP/Demo/Class/Contacts.php on line 3

And after trial and error I remove the public modifier of Contacts class, and the test become success without error.

Contacts.php (After remove the public modifier)

<?php 

    class Contacts {

    }
?>

Can anyone explain why in PHP I cannot use the public as modifier of a class?

    Because all classes are public in PHP. There's no such thing as a "private class".
