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


string get_html_translation_table (int table);

get_html_translation_table() will return the translation table that is used internally for htmlspecialchars() and htmlentities(). Ther are two new defines (HTML_ENTITIES, HTML_SPECIALCHARS) that allow you to specify the table you want.

Example 1. Translation Table Example

$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".

The cool thing is using array_flip() to change the direction of the translation.

$trans = array_flip ($trans);
$original = strtr ($str, $trans);

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

Note: This function was added in PHP 4.0.
