Description:
------------
the openssl_spki_export() function outputs the pubkey to stdout instead of in the return value as is suggested by the documentation on http://php.net/manual/en/function.openssl-spki-export.php.



Test script:
---------------
$ cat openssl_spki_export.php 
<?php
$spkac = 'MIICYDCCAUgwggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQDQtftB35r7naJsELxZyQj64Sshxu2QEtb0cWWbxijxduHR4JecLzBEHG4hKCRoIqSkRVFAWqWKxYIDq3JFNkA3172u0Dv2eNiTf+hQ/tNCzjtgUebeosJNalNCMz/HVNJWZaiN1as7wE6q+d8jTuZjQmEmN7g1jAqN5E2ntl5ABQk84/fzJyQLsYXfKcZYLeIxQOn9X8xLLUcW1oAsPmZj6sG/nbPmYBTyvC2eveVaW7//3ZY0WK8q0bREKu/YF1jj18W4OSAI0hWkjiKW7yVzZZHzEO71YaRA6CcfoOGx4HCA+VG09kCXdlHD9KHaEM4IoYXfimq1xE40LnOQx1dtAgMBAAEWIGZhNjFlYzgxMzY0OGFlMTU3NDY2NTQyN2NmZDhmZTFkMA0GCSqGSIb3DQEBBAUAA4IBAQARDf9DVVv8P/4xhmTEyJWMBd7gy55JqJ/aAusjMRqqlX19c3xOGofjbHlDsGB91rbX8AhrUqN1dJS69cjNgPuWv/ZgMEjm2mctajZYBdE7b1HBWx/B9nxSIt5esB+H+Lt74I4AWLWQb/Y4UXRdOxKgGS1uUMQEHPfH1hkf4OBEamI+PoVyksvQpNarTFXbybiGmNfRcc9kJFLrZTNLK/MtY8wHA0yai9tsJOn/kN+KnmaTqk18QwEV0Lco+4SmH8wEu3Xo/JMIa6S+MAsI8u/D0sgiRYk/PKW/VGPb17PLX1e9F4QZbRpNmpVUfS3MCE6afaw4vEvmsjBQnU3BHDAG';

Not changing to a doc bug as returning the string would be nicer than outputting it.
