* SquirrelMail html translation table documentation
|
|
*
|
|
* SquirrelMail provides own implementation of htmlentities() and
|
|
* get_html_translation_table() functions. Functions are called
|
|
* sq_get_html_translation_table() and sq_htmlentities(). They are
|
|
* included in functions/strings.php
|
|
*
|
|
* sq_htmlentities uses same syntax as functions available in php 4.1.0
|
|
* sq_get_html_translation_table adds third option that sets charset.
|
|
*
|
|
* <pre>
|
|
* string sq_htmlentities ( string string [, int quote_style [, string charset]])
|
|
* array sq_get_html_translation_table ( int table [, int quote_style [, string charset]])
|
|
* </pre>
|
|
*
|
|
* If sq_get_html_translation_table function is called with HTML_SPECIALCHARS option,
|
|
* it returns us-ascii translation table. If it is called with HTML_ENTITIES option,
|
|
* it returns translation table defined by charset. Function defaults to us-ascii charset
|
|
* and not to iso-8859-1.
|
|
*
|
|
* Why own functions are used instead of htmlspecialchars() and
|
|
* htmlentities() provided by php.
|
|
*
|
|
* <ul>
|
|
* <li>a) removes dependency on options available only in php v.4.1+</li>
|
|
* <li>b) default behavior of htmlentities() is disastrous in non iso-8859-1 environment.</li>
|
|
* <li>c) provides better control of transformations.</li>
|
|
* </ul>
