simple validation functions


Recommended Posts

Hi Guys


Simple question. Can anyone tell me why this doesn't work please?


$test = "<HEELOOOO";

$test2 = filter_var("$test", FILTER_SANITIZE_STRING);

echo $test2;


When I run this get I get nothing echoed back, not even in the source. So can the filter function not be used like this? I thought it would encode the special character and return it but I must be missing something simple here!
