Description:
------------
I have upgraded PHP on Linux from 4.3.1 to 4.3.8 versions (the configuration remains the same)

The following script ...
echo "php_self is $_SERVER['PHP_SELF']"; 
... was OK in 4.3.1

I got this error in 4.3.8 ...
Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING 

It seems that $_SERVER['PHP_SELF'] has changed is type (?).
If you try this code ...
   $code = '$_SERVER[\'PHP_SELF\']';
   foreach(token_get_all($code) as $c)
   {
       if(is_array($c))
       {
           print(token_name($c[0]) . ": '" . htmlentities($c[1]) . "'\n");
       }
       else
       {
           print("$c\n");
       }
   }

In 4.3.1, you get ...
T_INLINE_HTML: '$_SERVER['PHP_SELF']'

With 4.3.8, you get ...
T_VARIABLE: '$_SERVER'
[
T_CONSTANT_ENCAPSED_STRING: ''PHP_SELF''
]

Any idea ?

Reproduce code:
---------------
# very (too much ?) simple ...
echo "php_self is $_SERVER['PHP_SELF']"; 

Expected result:
----------------
php_self is /something/file.php

Actual result:
--------------
Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING
