PiTheNumber's answer was great but I ran into some issues with it that caused it to still print the headers to the page. So I adjusted it to use the more reliable curl_getinfo function. This version also follows redirects.

public function get_page_content( $url ) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
    curl_setopt($ch, CURLOPT_HEADER, 1);

    // Forward current cookies to curl
    $cookies = array();
    foreach ($_COOKIE as $key => $value) {
        if ($key != 'Array') {
            $cookies[] = $key . '=' . $value;
        }
    }
    curl_setopt( $ch, CURLOPT_COOKIE, implode(';', $cookies) );

    $destination = $url;

    while ($destination) {
        session_write_close();
        curl_setopt($ch, CURLOPT_URL, $destination);
        $response = curl_exec($ch);
        $curl_info = curl_getinfo($ch);
        $destination = $curl_info["redirect_url"];
        session_start();
    }
    curl_close($ch);

    $headers = substr($response, 0, $curl_info["header_size"]);
    $body = substr($response, $curl_info["header_size"]);

    // Extract cookies from curl and forward them to browser
    preg_match_all('/^(Set-Cookie:\s*[^\n]*)$/mi', $headers, $cookies);
    foreach($cookies[0] AS $cookie) {
        header($cookie, false);
    }

    return $body;
}
