   (PHP 4 >= 4.2.0)
   openssl_pkey_export_to_file -- Gets an exportable representation of a
   key into a file

Description

   bool openssl_pkey_export_to_file ( mixed key, string outfilename [,
   string passphrase [, array configargs]])

   openssl_pkey_export_to_file() saves an ascii-armoured (PEM encoded)
   rendition of key into the file named by outfilename. The key can be
   optionally protected by a passphrase. configargs can be used to
   fine-tune the export process by specifying and/or overriding options
   for the openssl configuration file. See openssl_csr_new() for more
   information about configargs. Returns TRUE on success or FALSE on
   failure.

     Note: You need to have a valid openssl.cnf installed for this
     function to operate correctly. See the notes under the installation
     section for more information.
