4085 |
* Secure replacement for PHP built-in function htmlspecialchars().
|
|
|
4086 |
*
|
|
|
4087 |
* See ticket #427 (http://wush.net/trac/wikka/ticket/427) for the rationale
|
|
|
4088 |
* for this replacement function.
|
|
|
4089 |
*
|
|
|
4090 |
* The INTERFACE for this function is almost the same as that for
|
|
|
4091 |
* htmlspecialchars(), with the same default for quote style; however, there
|
|
|
4092 |
* is no 'charset' parameter. The reason for this is as follows:
|
|
|
4093 |
*
|
|
|
4094 |
* The PHP docs say:
|
|
|
4095 |
* "The third argument charset defines character set used in conversion."
|
|
|
4096 |
*
|
|
|
4097 |
* I suspect PHP's htmlspecialchars() is working at the byte-value level and
|
|
|
4098 |
* thus _needs_ to know (or asssume) a character set because the special
|
|
|
4099 |
* characters to be replaced could exist at different code points in
|
|
|
4100 |
* different character sets. (If indeed htmlspecialchars() works at
|
|
|
4101 |
* byte-value level that goes some way towards explaining why the
|
|
|
4102 |
* vulnerability would exist in this function, too, and not only in
|
|
|
4103 |
* htmlentities() which certainly is working at byte-value level.)
|
|
|
4104 |
*
|
|
|
4105 |
* This replacement function however works at character level and should
|
|
|
4106 |
* therefore be "immune" to character set differences - so no charset
|
|
|
4107 |
* parameter is needed or provided. If a third parameter is passed, it will
|
|
|
4108 |
* be silently ignored.
|
|
|
4109 |
*

* In the OUTPUT there is a minor difference in that we use ''' instead
|
|
|
4111 |
* of PHP's ''' for a single quote: this provides compatibility with
|
|
|
4112 |
* get_html_translation_table(HTML_SPECIALCHARS, ENT_QUOTES)
|
|
|
4113 |
* (see comment by mikiwoz at yahoo dot co dot uk on
|
|
|
4114 |
* http://php.net/htmlspecialchars); it also matches the entity definition
|
|
|
4115 |
* for XML 1.0
|
|
|
4116 |
* (http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_Special_characters).
|
|
|
4117 |
* Like PHP we use a numeric character reference instead of ''' for the
|
|
|
4118 |
* single quote. For the other special characters we use the named entity
|
|
|
4119 |
* references, as PHP is doing.
