note 74187 added to ref.openssl

Currently, all OpenSSL Functions defined in PHP only utilize
the PEM format.  Use the following code to convert from DER
to PEM and PEM to DER.

<?php
$pem_data = file_get_contents($cert_path.$pem_file);
$pem2der = pem2der($pem_data);

$der_data = file_get_contents($cert_path.$der_file);
$der2pem = der2pem($der_data);

function pem2der($pem_data) {
   $begin = "CERTIFICATE-----";
   $end   = "-----END";
   $pem_data = substr($pem_data, strpos($pem_data,
$begin)+strlen($begin));	
   $pem_data = substr($pem_data, 0, strpos($pem_data,
$end));
   $der = base64_decode($pem_data);
   return $der;
}

function der2pem($der_data) {
   $pem = chunk_split(base64_encode($der_data), 64,
"n");
   $pem = "-----BEGIN
CERTIFICATE-----n".$pem."-----END
CERTIFICATE-----n";
   return $pem;
}
?>
