http - Can PHP cURL retrieve response headers AND body in a single request?

Question

Is there any way to get both headers and body for a cURL request using PHP? I found that this option:

curl_setopt($ch, CURLOPT_HEADER, true);

is going to return the body plus headers, but then I need to parse it to get the body. Is there any way to get both in a more usable (and secure) way?

Note that for "single request" I mean avoiding issuing a HEAD request prior of GET/POST.

One solution to this was posted in the PHP documentation comments: http://www.php.net/manual/en/function.curl-exec.php#80442

Code example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
// ...

$response = curl_exec($ch);

// Then, after your curl_exec call:
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

Warning: As noted in the comments below, this may not be reliable when used with proxy servers or when handling certain types of redirects. @Geoffrey's answer may handle these more reliably.
