How to remove multiple UTF-8 BOM sequences

Question

Using PHP5 (cgi) to output template files from the filesystem and having issues spitting out raw HTML.

private function fetch($name) {
    $path = $this->         


        

Answer 1

b'\xef\xbb\xbf' stands for the literal string "\xef\xbb\xbf". If you want to check for a BOM, you need to use double quotes, so the \x sequences are actually interpreted into bytes:

"\xef\xbb\xbf"

Your files also seem to contain a lot more garbage than just a single leading BOM:
