return; // would just stop the function
OR if you want to call the function from elsewhere like this : echo foo();
or $string=foo();
function foo(){
$html_construct='<html>';
$html_construct.='<title>chris is great</title>';
return $html_construct;
}

not sure about your question. The manual will give escapes for for example
switchs parts (break;) and others. See manual part II.11 Control structures.

In case the command before 'or; fails do what is after 'or'.
So if you connect succesfully the script continues, if something goes wrong
(wrong password, server down etc etc) the script does
die ('bla')
this means the script stops and the browsers shows 'bla'.
(except when you'r in the middle of building a page and the text is
invisible due to its location in the HTML, for example when a table is
opened before in Netscape but not closed yet.
