Bug #81342 New ampersand token parsing depends on new line after it
Submitted: 2021-08-10 05:56 UTC Modified: -
From: werlos at gmail dot com Assigned:
Status: Closed Package: Scripting Engine problem
PHP Version: 8.1.0beta2 OS: linux
Private report: No CVE-ID: None

Description:
------------
The "&" token is parsed as T_AMPERSAND_FOLLOWED_BY_VAR_OR_VARARG when space and then variable follows, but it's parsed to T_AMPERSAND_NOT_FOLLOWED_BY_VAR_OR_VARARG when newline and then variable follows.

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

$tokens = token_get_all('<?php $x & $x; $x &
    $baz;
');

var_dump($tokens[3][1]);
var_dump(token_name($tokens[3][0]));
var_dump($tokens[10][1]);
var_dump(token_name($tokens[10][0]));


Expected result:
----------------
string(1) "&"
string(37) "T_AMPERSAND_FOLLOWED_BY_VAR_OR_VARARG"
string(1) "&"
string(37) "T_AMPERSAND_FOLLOWED_BY_VAR_OR_VARARG"

Actual result:
--------------
string(1) "&"
string(37) "T_AMPERSAND_FOLLOWED_BY_VAR_OR_VARARG"
string(1) "&"
string(41) "T_AMPERSAND_NOT_FOLLOWED_BY_VAR_OR_VARARG"
