For example, in this example, we use the filter_input_array () function to filter the last three variables.

 

The variable after receiving the message is a name, age and e-mail address:

 

 array  (  "filter"=>FILTER_CALLBACK,  "flags"=>FILTER_FORCE_ARRAY,  "options"=>"ucwords"  ), "age" => array  (  "filter"=>FILTER_VALIDATE_INT,  "options"=>array   (   "min_range"=>1,   "max_range"=>120   )  ), "email"=> FILTER_VALIDATE_EMAIL, );print_r(filter_input_array(INPUT_POST, $filters));?>

Return Value diligence.
