| * 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. |
