/**
* Secure replacement for PHP built-in function htmlspecialchars().
*
* See ticket #427 (http://wush.net/trac/wikka/ticket/427) for the rationale
* for this replacement function.
*
* The INTERFACE for this function is almost the same as that for
* htmlspecialchars(), with the same default for quote style; however, there
* is no 'charset' parameter. The reason for this is as follows:
*
* The PHP docs say:
* "The third argument charset defines character set used in conversion."
*
* I suspect PHP's htmlspecialchars() is working at the byte-value level and
* thus _needs_ to know (or asssume) a character set because the special
* characters to be replaced could exist at different code points in
* different character sets. (If indeed htmlspecialchars() works at
* byte-value level that goes some way towards explaining why the
* vulnerability would exist in this function, too, and not only in
* htmlentities() which certainly is working at byte-value level.)
*
* This replacement function however works at character level and should
* therefore be "immune" to character set differences - so no charset
* parameter is needed or provided. If a third parameter is passed, it will
* be silently ignored.
*
* In the OUTPUT there is a minor difference in that we use ''' instead
* of PHP's ''' for a single quote: this provides compatibility with
* get_html_translation_table(HTML_SPECIALCHARS, ENT_QUOTES)
* (see comment by mikiwoz at yahoo dot co dot uk on
* http://php.net/htmlspecialchars); it also matches the entity definition
* for XML 1.0
* (http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_Special_characters).
* Like PHP we use a numeric character reference instead of ''' for the
* single quote. For the other special characters we use the named entity
* references, as PHP is doing.
