Data attribute: This value sends by the users/visitors or uses value created by the script. This value may use GET (form or address bar) or POST (form) method, and Cookie or Session value.

Type attribute: This value represents the type of data you want to achieve if you are sanitizing or the type of data you want to validate if you are validating. For sanitizing you can use; String, Float, Integer, URL, Email, or Special types. For validating you can use; Boolean, Float, Integer, Email, URL, Domain, IP, or MAC types.

Initialization

Simple initialization:

$filter = new SunFilter();

Sanitization

Using GET method (form or address bar)

$filter = new SunFilter();
$data = $filter->sanitize($_GET['val'], 'string')->result(); // use: string, float, integer, url, email, special
echo $data;

Using POST method (form)

$filter = new SunFilter();
$data = $filter->sanitize($_POST['val'], 'string')->result(); // use: string, float, integer, url, email, special
echo $data;

Using COOKIE value

setcookie('val', '<b>SunFilter Class</b>', time()+60*60);
$filter = new SunFilter();
$data = $filter->sanitize($_COOKIE['val'], 'string')->result(); // use: string, float, integer, url, email, special
echo $data;

Using SESSION value

$_SESSION['val'] = '<b>SunFilter Class</b>';
$filter = new SunFilter();
$data = $filter->sanitize($_SESSION['val'], 'string')->result(); // use: string, float, integer, url, email, special
echo $data;

Encoding HTML special chars

$filter = new SunFilter();
$data = $filter->sanitize($_GET['val'], 'special')->result(); // html-encode '"<>& and characters with ascii value less than 32
echo $data;

Validation

Using GET method (form or address bar)

$filter = new SunFilter();
$result = $filter->validate($_GET['val'], 'integer')->result(); // use: boolean, float, integer, email, url, domain, ip, mac
if ( $result == true) {
    echo 'Data is Integer.';
} else {
    echo 'Data is not Integer.';
}

Using POST method (form)

$filter = new SunFilter();
$result = $filter->validate($_POST['val'], 'integer')->result(); // use: boolean, float, integer, email, url, domain, ip, mac
if ( $result == true) {
    echo 'Data is Integer.';
} else {
    echo 'Data is not Integer.';
}

Using COOKIE value

setcookie('val', 'sample@domain.com', time()+60*60);
$filter = new SunFilter();
$result = $filter->validate($_COOKIE['val'], 'email')->result(); // use: boolean, float, integer, email, url, domain, ip, mac
if ( $result == true) {
    echo 'Data is Email.';
} else {
    echo 'Data is not Email.';
}

Using SESSION value

$_SESSION['val'] = 'sample@domain.com';
$filter = new SunFilter();
$result = $filter->validate($_SESSION['val'], 'email')->result(); // use: boolean, float, integer, email, url, domain, ip, mac
if ( $result == true) {
    echo 'Data is Email.';
} else {
