Bug 271272

Netbeans shows a syntax error when trying to use `array` as the name of a class constant in PHP.

```
class Type {
    const ARRAY = 'array';
}
print Type::ARRAY
```

Netbeans shows the following syntax errors:

```
Syntax error:
 unexpected:  array
 after:       const
 expected:    identifier
```
and
```
Syntax error:
 unexpected:  array
 after:       ::
 expected:    identifier, variable, {, define, $
```

There should be no syntax errors.

From http://php.net/manual/en/reserved.keywords.php ('array()' is listed as a reserved keyword):

> As of PHP 7.0.0 these keywords are allowed as property, constant, and method names of
> classes, interfaces and traits, except that class may not be used as constant name.
