# get_html_translation_table

(PHP 4 , PHP 5)

get_html_translation_table -- Returns the translation table used by htmlspecialchars() and htmlentities()

## Description

array get_html_translation_table ( int table [, int quote_style])

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

There are two new constants (`HTML_ENTITIES`, `HTML_SPECIALCHARS`) that allow you to specify the table you want. And as in 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().

示範 1.Translation Table Example
`<?php $trans = get_html_translation_table(HTML_ENTITIES); $str = "Hallo & <Frau> & Kr鄝er"; $encoded = strtr($str, $trans); ?>`

The $encoded variable will now contain: "Hallo &amp; &lt;Frau&gt; &amp; Kr&auml;mer".

Another interesting use of this function is to, with help of array_flip(), change the direction of the translation.

`<?php $trans = array_flip($trans); $original = strtr($encoded, $trans); ?>`

The content of $original would be: "Hallo & <Frau> & Krämer".

See also htmlspecialchars(), htmlentities(), strtr(), and array_flip().
