4087. * Secure replacement for PHP built-in function htmlspecialchars().
4088. *
4089. * See ticket #427 (http://wush.net/trac/wikka/ticket/427) for the rationale
4090. * for this replacement function.
4091. *
4092. * The INTERFACE for this function is almost the same as that for
4093. * htmlspecialchars(), with the same default for quote style; however, there
4094. * is no 'charset' parameter. The reason for this is as follows:
4095. *
4096. * The PHP docs say:
4097. * "The third argument charset defines character set used in conversion."
4098. *
4099. * I suspect PHP's htmlspecialchars() is working at the byte-value level and
4100. * thus _needs_ to know (or asssume) a character set because the special
4101. * characters to be replaced could exist at different code points in
4102. * different character sets. (If indeed htmlspecialchars() works at
4103. * byte-value level that goes some way towards explaining why the
4104. * vulnerability would exist in this function, too, and not only in
4105. * htmlentities() which certainly is working at byte-value level.)
4106. *
4107. * This replacement function however works at character level and should
4108. * therefore be "immune" to character set differences - so no charset
4109. * parameter is needed or provided. If a third parameter is passed, it will
4110. * be silently ignored.
4111. *
4112. * In the OUTPUT there is a minor difference in that we use '&#39;' instead
4113. * of PHP's '&#039;' for a single quote: this provides compatibility with
4114. * get_html_translation_table(HTML_SPECIALCHARS, ENT_QUOTES)
4115. * (see comment by mikiwoz at yahoo dot co dot uk on
4116. * http://php.net/htmlspecialchars); it also matches the entity definition
4117. * for XML 1.0
4118. * (http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_Special_characters).
4119. * Like PHP we use a numeric character reference instead of '&apos;' for the
4120. * single quote. For the other special characters we use the named entity
4121. * references, as PHP is doing.
