From manual page: http://www.php.net/function.openssl-pkey-new#refsect1-function.openssl-pkey-new-description

The resulting resource cannot be used with openssl_pkey_get_public as stated.

At least not always.

Maybe that statement is only valid for some inputs for the config?

If so, clarification is needed, preferably identifying the sorts of keys where the statement is applicable.

Test script:
---------------
$key_pair = openssl_pkey_new(array('digest_alg'=>'sha1', 'private_key_bits'=>1024, 'private_key_type'=>OPENSSL_KEYTYPE_RSA));

var_dump($key_pair);

$public = openssl_pkey_get_public($key_pair);
var_dump($public);


Expected result:
----------------
resource (4) of type (OpenSSL key)


Actual result:
--------------
