Good News: The T_DNUMBER error is gone, but makes absolutely no sense
why it's gone, you CAN use '$1' - '$9' in regular expressions!
Bad News: The pattern match failed to find the pattern to make the
substitution using your code:
[PHP]
$pattern='`^(\s*\*\s+\@version)\s*('.
str_replace('/','\\/',preg_quote($oldversion)).')(.*)$`i';
$contents = preg_replace($pattern, '\\1 ' . $newversion,
$contents);
[/PHP]
So it's half fixed :)
