This is a problem:

/*
	$pnr=preg_replace("/[a-zA-Z]*/", "", $pnr);
*/	

As you can see this is a line that has been commented out.
The problem is that the engine thinks that the "*/" within the REGEX itself is the end of the comment making it impossible to comment this line out.
This is a big problem if you have a whole block of expressions containing REGEX which you want to comment out!

What about a fix?

Right. Engine cannot parse your comments as if they were PHP
code (because they are not), so be careful.
