Usage

use MaiVu\Php\Filter;

// Syntax
Filter::clean($source, $type);

// Example
$source = '<h1>Hello World!</h1>';

// Return 'Hello World!'
$filtered = Filter::clean($source, 'string');

// Source array
$source = [
	'<h1>Hello World!</h1>',
	'<h1>Hello VietNam!</h1>',
];

// Return ['Hello World!', 'Hello VietNam!']
$filtered = Filter::clean($source, 'string:array');

// Multi-type
$source = '  <h1>Hello World!</h1>  ';

// Return 'Hello World!'
$filtered = Filter::clean($source, ['string', 'trim']);

Add new custom rule

use MaiVu\Php\Filter;
Filter::setRule('custom', function($value) {
    return $value . ' is filtered by a Closure';
});

$source = 'Hello World!';

// Return 'Hello World! is filtered by a Closure'
$filtered = Filter::clean($source, 'custom');

// The same above
Filter::clean($source, function($value) {
    return $value . ' is filtered by a Closure';
});

Extend filters

use MaiVu\Php\Filter;

class CustomFilter extends Filter
{
	public static function arrayInteger($value)
	{
		return static::clean($value, 'int:array');
	}
}

// Return '[1, 2, 3]'
echo '<pre>' . print_r(CustomFilter::clean(['1abc2', '2b', 3], 'arrayInteger'), true) . '</pre>';
