php – get_html_translation_table function


(PHP 4, PHP 5)

get_html_translation_table — Returns the translation table used by htmlspecialchars() and htmlentities()
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. Default value for table is HTML_SPECIALCHARS. 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().

Note: Special characters can be encoded in several ways. E.g. ” can be encoded as “, ” or “. get_html_translation_table() returns only the most common form for them.

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 & <Frau> & Krämer”.
