[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.

Niesamowite. Kod na odwal się żeby zachować kompatybilność ma mniej linii niż Twój do ustalenia daty.

[PHP] pobierz, plaintext 
final class Nbp {
    private array $data;
    private array $transformedData;
    private array $mappings = [
        'Euro' => 'EUR',
        'Dolar' => 'USD',
        'Frank' => 'CHF',
    ];
 
    public function __construct(array $data) {
        $this->data = $data;
        $this->transformData();
    }
 
    public function getEffectiveDate(): string {
        return $this->data[0]['effectiveDate'];
    }
 
    private function transformData(): void {
        $this->transformedData = array_column($this->data[0]['rates'], 'mid', 'code');
    }
 
    private function searchMappings($name): ?string {
        $currency = substr($name, 3, strlen($name));
        return $this->mappings[$currency] ?? null;
    }
 
    public function __call($name, $arguments): ?string {
        return $this->transformedData[$this->searchMappings($name)] ?? null;
    }
}
 
$nbp = new Nbp(json_decode($data, true));
echo $nbp->getEuro();
echo $nbp->getEffectiveDate();
