openssl_csr_get_subject — CSR の subject を返す
説明
openssl_csr_get_subject(OpenSSLCertificateSigningRequest|string
$csr, bool $short_names = true): array|false
openssl_csr_get_subject() 関数は、
csr にエンコードされた subject の識別名の情報を返します。
commonName (CN), organizationName (O), countryName (C) などが含まれます。
パラメータ
戻り値
subject の説明を記した連想配列を返します。失敗した場合に false を返します
変更履歴
| バージョン | 説明 |
|---|---|
| 8.0.0 |
csr は、
OpenSSLCertificateSigningRequest クラスのインスタンスを受け入れるようになりました。

例
例1 openssl_csr_get_subject() の例
<?php
$subject = array(
"countryName" => "CA",
"stateOrProvinceName" => "Alberta",
"localityName" => "Calgary",
"organizationName" => "XYZ Widgets Inc",
"organizationalUnitName" => "PHP Documentation Team",
"commonName" => "Wez Furlong",
"emailAddress" => "wez@example.com",
);
$private_key = openssl_pkey_new(array(
"private_key_bits" => 2048,
"private_key_type" => OPENSSL_KEYTYPE_RSA,
));
$configargs = array(
'digest_alg' => 'sha512WithRSAEncryption'
);
$csr = openssl_csr_new($subject, $privkey, $configargs);
print_r(openssl_csr_get_subject($csr));
?>上の例の出力は、 たとえば以下のようになります。
Array
(
[C] => CA
[ST] => Alberta
[L] => Calgary
[O] => XYZ Widgets Inc
[OU] => PHP Documentation Team
[CN] => Wez Furlong
[emailAddress] => wez@example.com
)

this function does not yet return SANs (subject alternative names) fields for UC certificates like those used in exchange 2007.

This function may not return name fields in the order they appear in the certificate. For example, this CSR:
-----BEGIN CERTIFICATE REQUEST-----
MIHsMIGUAgEAMDIxEDAOBgNVBAsMB3VuaXQgIzExDDAKBgNVBAoMA29yZzEQMA4G
A1UECwwHdW5pdCAjMjBZMBMGByqGSM49AgEGCCqGSM49AwEHA0IABGvZnFxGuVzJ
hOKPs5RNxZBS4vY6ERaqm5tKMGOhxLSfv/dpjDtNNdSHkIGNjYxclHYhxG0ku7BY
PA5uPIjng1SgADAKBggqhkjOPQQDAgNHADBEAiB4GXhhbEU1UFTCe0dwJnKHTQuI
xzYL5FnyhmKdixN/0gIgBXSm9S8L/oJ6rBxemin/V/xKv5jy4TEZuz84nnshxQQ=
-----END CERTIFICATE REQUEST-----
When processed by 'openssl -noout -subject' gives this:
subject=/OU=unit #1/O=org/OU=unit #2
On the other hand, 'var_dump( openssl_csr_get_subject( "..." ) )' will produce this:
csr = array(2) {
["OU"]=>
array(2) {
[0]=>
string(7) "unit #1"
[1]=>
string(7) "unit #2"
}
["O"]=>
string(3) "org"
}
As you can see, ordering information (which may be important for some applications) is lost.

The returning assoziative array is indexed with the fields
in the subject so you should have a array key named CN,OU and so on.
