In the pattern you ask for '; ?>', i.e. semi-colon-space-questionmark.

In the code snippet you provided, there is more than one space behind
the semi-colon, ergo: it is correct that the pattern does not match the
code snippet.

If more spaces are allowable, you can of course solve this by changing:
> $pattern .= "\?php.*\(.*\); \?";

to:
> $pattern .= "\?php.*\(.*\); +\?";
