Returns the translation table used by
<function>htmlspecialchars</function> and
<function>htmlentities</function>

</methodsynopsis>
<para>
<function>get_html_translation_table</function> will return the
translation table that is used internally for
<function>htmlspecialchars</function> and
<function>htmlentities</function>.
</para>
<para>
There are two new constants
(<constant>HTML_ENTITIES</constant>,
<constant>HTML_SPECIALCHARS</constant>) that allow you to
specify the table you want. Default value for <parameter>table</parameter>
is <constant>HTML_SPECIALCHARS</constant>. And as in the
<function>htmlspecialchars</function> and
<function>htmlentities</function> functions you can optionally
specify the <parameter>quote_style</parameter> you are working with. The default is
<constant>ENT_COMPAT</constant> mode. See the description of these modes in
<function>htmlspecialchars</function>.
</para>
<para>
<example>
<title>Translation Table Example</title>
<programlisting role="php">
<![CDATA[
<?php
$trans = get_html_translation_table(HTML_ENTITIES);
$str = "Hallo & <Frau> & Krmer";
$encoded = strtr($str, $trans);
?>
]]>
</programlisting>
</example>
The <literal>$encoded</literal> variable will now contain:
<literal>"Hallo &amp; &lt;Frau&gt; &amp;
Kr&auml;mer".</literal>
</para>
<para>
Another interesting use of this function is to, with help of <function>array_flip</function>,
change the direction of the translation.
<informalexample>
<programlisting role="php">
<![CDATA[
<?php
$trans = array_flip($trans);
$original = strtr($encoded, $trans);
?>
]]>
</programlisting>
</informalexample>
The content of <literal>$original</literal> would be: "Hallo &
<Frau> & Krämer".
</para>
<para>

<function>htmlentities</function>,
<function>strtr</function>, and
<function>array_flip</function>.
