Recursive functions come in handy here…
function __stripslashes($var)
{
$var = is_array($var) ? array_map(‘__stripslashes’, $var) : stripslashes($var);

return $var;
}
function __htmlspecialchars($var, $style)
{
$var = is_array($var) ? array_map(‘__htmlspecialchars’, $var, array_fill(0, count($var), $style)) : htmlspecialchars($var, $style);

return $var;
}
$_GET = __stripslashes($_GET);
$_GET = __htmlspecialchars($_GET, ENT_QUOTES);

You can simplify, you don’t need to assign the variable to a variable to the function results. i.e. instead of

$cleanPost = array_map(’confHtmlEnt’, $_GET);
$_GET=$cleanPost;

do

$_GET = array_map(’confHtmlEnt’, $_GET);

A nice function is


function cleanData($data) {
$data = trim($data);
$data = htmlentities($data);
$data = mysql_real_escape_string($data);
}

$_POST = array_map('cleanData', $_POST);


function confHtmlEnt($data)
{…}

$cleanPost = array_map(‘confHtmlEnt’, $_GET);
$_GET=$cleanPost;
And avoid analizing my vars case by case.
