Bug description:token_get_all with regards to __halt_compiler is not binary safe
Description:
------------
A. token_get_all() eats some characters which are not allowed in plain PHP
code and trigger a "Unexpected character in input" warning.
B. after a T_HALT_COMPILER, the tokens are still identified as if they were
not after this T_HALT_COMPILER, when in reality they are just random data.
So, when using token_get_all on code which contains a T_HALT_COMPILER, the
data after that is corrupted because of A.
Test script:
---------------
<?php
$code = "<?php __halt_compiler();\x01?>\x02";
$tokens = token_get_all($code);
$reconstructed_code = '';
foreach ($tokens as $t)
{
$reconstructed_code .= isset($t[1]) ? $t[1] : $t;
}
var_dump($code);
var_dump($reconstructed_code);
Expected result:
----------------
string(28) "<?php __halt_compiler();?>"
string(28) "<?php __halt_compiler();?>"
Actual result:
--------------
PHP Warning: Unexpected character in input: '' (ASCII=1) state=0 on line
5
string(28) "<?php __halt_compiler();?>"
string(27) "<?php __halt_compiler();?>"
