-----END CERTIFICATE-----
```

The following code:
```php
$cert = openssl_x509_parse(file_get_contents(__DIR__ . DIRECTORY_SEPARATOR. "cert.pem"));

# remove some fields to reduce output length
unset ($cert["purposes"]);
unset ($cert["extensions"]);

print_r($cert);
```

Resulted in this output:
```
Array

    [name] => /C=DE/ST=BY/L=Munich/O=Awesome Company/OU=CEO of Gummibears/CN=Mentor of the Jungle/[email protected]
    [subject] => Array

```

But I expected this output instead:
```
