get_html_translation_table

Returns the translation table used by htmlspecialchars and htmlentities (PHP 4 )
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().

Example 917. Translation Table Example

copy to clipboard
<?php
$trans = get_html_translation_table(HTML_ENTITIES);
$str = "Hallo & <Frau> & Krämer";
$encoded = strtr($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.

copy to clipboard
<?php
$trans = array_flip($trans);
$original = strtr($encoded, $trans);
?>

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