Description:
------------
Thanks to https://wiki.php.net/rfc/context_sensitive_lexer it's possible in PHP7 to use a lot of keywords as constants, methods etc.

However token_get_all doesn't return the right tokens.

Test script:
---------------
<?php

$tokens = token_get_all('<?php class Test {const PUBLIC=0;}');

foreach ($tokens as $token) {
	if (is_array($token)) {
		echo token_name($token[0]) . "\n";
	}
}


Expected result:
----------------
T_OPEN_TAG
T_CLASS
T_WHITESPACE
T_STRING
T_WHITESPACE
T_CONST
T_WHITESPACE
T_STRING
T_LNUMBER

Actual result:
--------------
T_OPEN_TAG
T_CLASS
T_WHITESPACE
T_STRING
T_WHITESPACE
T_CONST
T_WHITESPACE
T_PUBLIC
T_LNUMBER
