Description:
------------
On the https://www.php.net/manual/en/language.oop5.basic.php
There is a typo
It said that
print Some\Class\DoesNot\Exist::class;

will print Some\Class\Does\Not\Exist

But it will not, there are 2 problems:
Word Class in the namespace, missing slash for print statement DoesNot\Exist instead of Does\Not\Exist 

Test script:
---------------
print Some\Class\DoesNot\Exist::class;

Expected result:
----------------
print Does\Not\Exist::class;

will print Does\Not\Exist

Actual result:
--------------
Parse error:  syntax error, unexpected 'Class' (T_CLASS), expecting identifier (T_STRING) in php shell code on line 1

> Word Class in the namespace,
As of PHP 8, using "Class" is okay because the namespace name is considered as a whole. https://3v4l.org/AEJP5

A revised example avoiding that issue and fixing the backslash would be

<?php
print Does\Not\Exist::class;
?>
