// Replace [br] with <br />
    $this->bbcode_table["/\[br\]/is"] = function ($match) {
      return "<br/>";
    };

    // Replace [p]...[/p] with <p>...</p>
    $this->bbcode_table["/\[p\](.*?)\[\/p\]/is"] = function ($match) {
      return "<p>$match[1]</p>";
    };

if $escapeHTML=true than
it escapes [quote="person"]...[/quote] and doesn't render the new BBcode to hrml.
added: ENT_NOQUOTES to render correctly the BBcode.

added additional BBcode tags and some alternatives.
also updated to current "https" protocol.

usage:
$bbcode = new BBCode;

$_str = [email=someone@somewhere.com]An e-mail link ;

 // will return: [email=someone@somewhere.com]An e-mail link[/email]
$formated_BBcode = $bbcode->checkTag($_str);

//will return: <a href="mailto:someone@somewhere.com">An e-mail link</a>
$formated_html = $bbcode->toHTML($formated_BBcode);

echo $formated_html;

added additional tags
