使用 PHP5 (cgi) 从文件系统输出模板文件并且在输出原始 HTML 时遇到问题.

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

private function fetch($name) {
    $path = $this->j->config['template_path'] . $name . '.html';
    if (!file_exists($path)) {
        dbgerror('Could not find the template "' . $name . '" in ' . $path);
    }
    $f = fopen($path, 'r');
    $t = fread($f, filesize($path));
    fclose($f);
    if (substr($t, 0, 3) == b'xefxbbxbf') {
        $t = substr($t, 3);
    }
    return $t;
}

即使我添加了 BOM 修复，我仍然遇到 Firefox 接受它的问题.您可以在此处查看实时副本:http://ircb.in/jisti/(以及模板文件我如果你想检查它，请扔在 http://ircb.in/jisti/home.html出)

Even though I've added the BOM fix I'm still having problems with Firefox accepting it. You can see a live copy here: http://ircb.in/jisti/ (and the template file I threw at http://ircb.in/jisti/home.html if you want to check it out)

知道如何解决这个问题吗?o_o

Any idea how to fix this? o_o

    $bom = pack('H*','EFBBBF');
    $text = preg_replace("/^$bom/", '', $text);
    return $text;
}
