从PHP中的另一个站点的页面中提取内容的最小脚本

Question

Very simple thing. I sometimes want to access urban dictionary but it is blocked where I am. Given a form like

<form method="get" action="<?PHP echo htmlspecialchars($_SERVER['PHP_SELF']); ?>">
<input type="text" name="what" value="" />
<input type="submit" />
</form>

what do I need to add to have it return the content of the entry from urban dictionary for value entered? For example using CURL or getFile or something as simple as possible

Update:

This works!

<form method="get" action="">
<input type="text" name="what" value="" />
<input type="submit" />
</form>

<?PHP
$what = isSet($_GET["what"])?htmlentities($_GET["what"]):"";
echo file_get_contents("http://www.urbandictionary.com/define.php?term=".urlencode($what));
?>

Answer 1

very simple, very weird file_get_contents($_POST['what']);
