get_html_translation_table

(PHP 4, PHP 5)

get_html_translation_tableReturns the translation table used by htmlspecialchars() and htmlentities()

Description

array get_html_translation_table ([ int $table = HTML_SPECIALCHARS [, int $quote_style = ENT_COMPAT [, string $charset_hint ]]] )

get_html_translation_table() will return the translation table that is used internally for htmlspecialchars() and htmlentities() with the default charset.

Note:

Special characters can be encoded in several ways. E.g. " can be encoded as ", " or &#x22. 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.

quote_style

Like the htmlspecialchars() and htmlentities() functions you can optionally specify the quote_style you are working with. See the description of these modes in htmlspecialchars().

charset_hint

Like htmlentities(), it takes an optional third argument charset which defines character set used in conversion. Presently, the ISO-8859-1 character set is used as the default.

Following character sets are supported in PHP 4.3.0 and later.
