You can't use this function to export a public key
Warning: openssl_pkey_export_to_file(): supplied key param is a public key
On Linux (PHP5.6), this function will overwrite an existing keyfile, unless the keyfile is marked as read-only, in which case you will get an error:
error:0200100D:system library:fopen:Permission denied
