Still too much typing ;) , try this:
$t = R('test',0,'int');
function R($k,$def = null,$type = null)
{
if (!isset($_REQUEST[$k])) {
return $def;
}
if (isset($type)) {
return checktype($type,$_REQUEST[$k],$def);
}
return $_REQUEST[$k];
}
function checktype($type,$v,$def = null)
{
switch ($type) {
case 'int':
case 'integer':
if ((string)intval($v) !== strval($v)) {
return $def;
}
return intval($v);
case 'string':
if (!is_string($v)) {
return $def;
}
break;
}
return $v;
}
Mix up some additional flavors for $_GET, $_POST, etc and have some real
fun.
