(PHP 4, PHP 5)
get_html_translation_table — Returns the translation table used by htmlspecialchars() and htmlentities()
get_html_translation_table() will return the translation table that is used internally for htmlspecialchars() and htmlentities().
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.
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.
Like 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().
Returns the translation table as an array.
Example #1 Translation Table Example
<?php
$trans = get_html_translation_table(HTML_ENTITIES);
$str = "Hallo & <Frau> & Kr?mer";
$encoded = strtr($str, $trans);
echo $encoded;
?>
上例将输出：
Hallo &amp; &lt;Frau&gt; &amp; Kr&auml;mer
