[php] examples/strings.php has a BOM--files cannot have BOM!!

[kaby76]

The templates for testing do not consider BOM in a file input. All files cannot have BOM. php/examples/strings.php contains a BOM. For TypeScript, the file is opened and read via readFileSync() into a string. That should have gotten rid of the BOM but it does not. The encoding parameter is "utf-8", but it does not automatically handle BOM. Instead, it considers it as a character. What a lovely language TypeScript/JavaScript is----NOT!!!

I can fix this file, but for future problems, the templates need to cut this BS out. NO BOM!!!!
