How to Completely Remove UTF-8 BOMs from PHP CGI Output to Fix HTML Rendering Issues?

Troubleshooting UTF-8 BOM Removal in PHP CGI

Encountering issues while outputting raw HTML from template files on the filesystem using PHP5? One potential culprit could be the presence of multiple UTF-8 BOM (Byte Order Mark) sequences. While the provided code snippet attempts to remove the initial BOM, it may not entirely resolve the issue.

To address this, consider implementing a more comprehensive function to remove all UTF-8 BOM occurrences from a given string:

function remove_utf8_bom($text) {
    $bom = pack('H*','EFBBBF'); // BOM in hex
    $text = preg_replace("/^$bom/", '', $text); // Remove leading BOM
    return $text;
}

By utilizing this function, you can ensure that all UTF-8 BOMs are removed, potentially resolving the issue encountered with Firefox accepting the HTML output. This ensures the correct rendering of your template files.
