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