get_html_translation_table() will return the translation table that is used internally for htmlspecialchars() and htmlentities().
Note: Special characters can be encoded in several ways. E.g. " can be encoded as ", " or ". get_html_translation_table() returns only the most common form for them.
Parameters
table
There are two new constants (HTML_ENTITIES, HTML_SPECIALCHARS) that allow you to specify the table you want. Default value for table is HTML_SPECIALCHARS.
quote_style
Like the htmlspecialchars() and htmlentities() functions you can optionally specify the quote_style you are working with. The default is ENT_COMPAT mode. See the description of these modes in htmlspecialchars().
