get_html_translation_table

(PHP 4 >= 4.0.0)

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

Description

string 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 defines (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 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.
