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.
