Here is a problem that I have had for years now.  I have been trying to come up
with the perfect solution for this problem.  But, I have come down to two
different methods for solving it.

Here is the problem...


function sendEmail(
    ) { # I typically do not put each argument on seperate lines, but I ran
        #out of width in this email...

    # do something here...


    'Check out my new pictures!!!',

Now, we all have a function or method like this floating around somewhere.

My question is, how do YOU go about setting the required entries of the $headers
array() ?

I see three possible solutions.  I want to see a clean and simple solution.

Here are my ideas so far:

function sendEmail(
    ) { # I typically do not put each argument on seperate lines, but I ran
        #out of width in this email...

    if ( empty($headers['Date']) ) {
        $headers['Date'] = date('c');
    if ( empty($headers['Message-ID']) ) {
        $headers['Date'] = md5($to.$subject);
    # and the example goes on...

    # do something here...


Or, another example.  (I will keep it to the guts of the solution now)

    $headers['Date']       = empty($headers['Date']) ?
                             date('c') : $headers['Date'];
    $headers['Message-ID'] = empty($headers['Message-ID']) ?
                             md5($to.$subject) : $headers['Message-ID'];

OR, yet another example...

$defaults = array(
    'Date'       => date('c'),
    'Message-ID' => md5($to.$subject),

$headers += $defaults;

END of examples...

Now, IMO, the last one is the simplest one and for me, I think it will be the
new way that I solve this type of problem.

But, my question that I put out to all of you is...

        How would you solve this problem?

To me the key word in your question is "default". Here is a send mail example of how I do it. You'll see that I assign default stuff in the function. The all caps are constants set in my config file. For extremely high volume applications, one could memory cache the defaults.

I also use arrays assigned in my config file and then assign the array in the function using "global". When I do this, I immediately reassign the array so the function can't change the the assignments made in the config. e.g.,

function foo()
global booArray();

boo2Array= booArray(); Only use boo2Array() in the function.

function pearEmailSend($recipient, $emailSubj, $emailText, $applicEmailAddr)
    $emailTo = $recipient;
    $headers['From'] = $applicEmailAddr;
    $headers['To'] = $emailTo;
    if(!empty($emailCC)) $headers['Cc'] = $emailCC;
$headers['Return-Path'] = $applicEmailAddr; //or can use SMTP_USER; bounces are sent to applic address
    $headers['Reply-To'] = $applicEmailAddr;
    $headers['X-miniReg'] = APPLIC_NAME;
    $headers['Date'] = date('r');
    $headers['Subject'] = $emailSubj;
$params['debug'] = EMAIL_DEBUG; //Careful, do not leave on, creates a nasty message for admins
    $params['host'] = $_SERVER['SERVER_NAME'];
    $params['auth'] = true; //binary, set in config; some servers require auth
$params["username"] = $applicEmailAddr; //was SMTP_USER; //If auth true, must have value
    $params["password"] = SMTP_PW; //If auth true, must have value
    $params["localhost"] = $_SERVER['SERVER_NAME'];
    $params['persist'] = true; //Default true
    $mail_object = @Mail::factory(EMAIL_MODE, $params);
