reverse of htmlentities()

[searain]

is there a reverse for htmlentities()?

in php.net, it says

There is no reverse of this function. However, you can create one on your own. Here is an example of how to do this.

Example 1. Reverse of htmlentities()

<?php
function unhtmlentities ($string)
{
$trans_tbl = get_html_translation_table (HTML_ENTITIES);
$trans_tbl = array_flip ($trans_tbl);
return strtr ($string, $trans_tbl);
}
?>

---

could anybody give me a case why we need reverse of htmlentities() ?

[dannys]

htmlentities -- Convert all applicable characters to HTML entities

so

unhtmlentities -- Convert all applicable HTML entities to characters

The latter would be needed if you wanted to convert &lt; back into < for example.

Otherwise you can (maybe) use the following function:

htmlspecialchars();
