[PHP]preg_match_all - problem Opcje

[casperii]

panowie , przejdę od razu do rzeczy, kod:

[PHP] pobierz, plaintext 
public function __construct($url = 'http://api.nbp.pl/api/exchangerates/tables/A/2020-04-02')
{
$this->_url = $url;	
}
 
 
$html = file_get_contents($this->_url . '');
$pattern = '/\/tables\/A\/^[0-9]{4}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1])$/';
preg_match_all($pattern, $html, $matches);
if (!isset($matches[0][0])) {
	throw new Exception('Unable to find XML filepath!');
}
 
$xml = file_get_contents($this->_url . $matches[0][0]);
if (!file_exists($this->_cache)) {
	if (!mkdir($this->_cache)) {
		throw new Exception('Unable to create cache directory!');
	}
}
if (!file_put_contents($filepath, $xml)) {
	throw new Exception('Unable to save file in cache directory!');
}
return $xml;
[PHP] pobierz, plaintext 

Niestety zwraca throwa Unable to find XML filepath , ktoś podpowie ? Chodzi o pobranie "2020-04-02" i zapisanie w katalogu na ftp.
