#1 How the function works

All the examples on sanitize_text_field() are relevant, for example:

wc_clean( 'Check <em>how</em>
cleared (string) <br>. ' );
//> 'Let's check how (string) is cleared .'

wc_clean( 'http://example.com/foo.php#bar' );
//> 'http://example.com/foo.php#bar'

It is also possible to process an array:

$data = [
	'say' => 'Hello,<br>user!',
	'<p>Paragraph with text</p>',
	'Plain Text',
];

wc_clean( $data );

/*
Array
(
	[say] => Hello,user!
	[0] => Paragraph with text
	[1] => Plain Text
)
*/
