====== Input_Item Class ======

The **Input_Item** class filters the GPCS data.

===== Quick Example =====
<PHP>
// Initiate class
$Input = new Input;

// fetches the key 'name' from GET
// initiates Input_Item and returns the object
$name = $Input->get ('name');

// $name is now an instance of Input_Item

echo 'Hello, ', $name->value ('Guest'); // prints 'Guest' if 'name' is not set or invalid.
</PHP>

===== Filtering the data =====
<PHP>
$age = $Input->get ('age')->apply_filters (FILTER_VALIDATE_INT);

if ($age->is_valid()
    // 'age' is validated as an integer
   
    if ($age->validate ('in_range', array ('min' => 18, 'max' => 110))) {
        // the person is within the age 18-110
    }  
}    
</PHP>
