When generating public key and then reading it with function openssl_pkey_get_public – $publicKeyResource = bool(false) and message:
error:0906D06C:PEM routines:PEM_read_bio:no start line

$privateKey = openssl_pkey_new(array('private_key_bits' => 2048, 'private_key_type' => OPENSSL_KEYTYPE_RSA));

$keyDetails = openssl_pkey_get_details($privateKey);

$publicKeyResource = openssl_pkey_get_public($keyDetails['key']);

What is wrong?

P.S.

privateKey = 

array(3) {
  ["bits"]=>int(2048)

  ["key"]=>
  string(451) "-----BEGIN PUBLIC KEY-----
