[PHP-INSTALL] syntax error, unexpected '&' in /etc/php/php.ini on line 107

Hi all,

I have a peculiar problem. My http error log is flooded with these two
lines over and over again:

PHP:  syntax error, unexpected '&' in /etc/php/php.ini on line 107
PHP:  syntax error, unexpected '&' in /etc/php/php.ini on line 108

My /etc/php/php.ini's lines 104 through 109 are:

104   ; error_reporting
105   ;   Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
106   ;   Development Value: E_ALL
107   ;   Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
108
109   ; html_errors

Everything above these lines is commented, except for the first line,
that reads:

[PHP]

So the &s on line 107 are to be expected, and line 108 is empty. Does
anyone have any idea what's going on here? Is this a bug?

Thanks!
