Re: How do YOU set default function/method params?

Ok, bad example. I already use SwiftMailer.  My "problem" though has nothing to do with sending an 
email.  I should have known someone would take it too literally.

Think a little more general.  This is not a specific thing to simply sending an email.

Could be database method calls from a class object, HTML CGI function, etc...

As for a different example.  Say you had a function that you had to pass (multiple) arguments to. 
But, with those arguments, you had defaults that you would like to inside the function even if they 
were not sent when you called your function.  But you do not want to be forced into entering ALL the 
arguments of a function call in a certain order.

Try this

function createHTMLBox($title, $content, $params=array() ) {

    $defaults = array(
        'id'     = uniq(),
        'class'  = 'box',
        'encode' = TRUE,
    );

    $params += $defaults;

    if ( $params['encode'] ) {
        $title   = htmlspecialchars($title);
        $content = htmlspecialchars($content);
    }

    # Obviously, I will be using the DomDocument class for this in the real world
    # But for simplicities sake, I used the following.
    $box = <<<BOX

<div id="{$params['id']}" class="{$params['class']}">
  <h4 class="boxTitleBar">{$title}</h4>
  <div class="boxContent">{$content}</div>
</div>

BOX;

    return $box;

}


Then, I call it like this:

echo createHTMLBox('This is my TITLE',
               '<ul><li>Item 1</li><li>Item 2</li></ul>',
               array('encode' => FALSE));

echo createHTMLBox('This is my TITLE',
               '<ul><li>Item 1</li><li>Item 2</li></ul>');

Both of the above will have different output to the screen.

Hope this clears things up.
