How can I rewrite my class for PHP 5 to emulate the functionality I had in PHP 4 in an error free way?
Have you tried this:
function format_string($string) {
// format the string...
$result = string;
if (isset($this)) $this->elements[] = $result;
return $result;
}In this form you can check the existance of $this. If you call the method statically then $this is not present and the elements array is not filled. If you call it non-statically then $this is present and elements is filled. The same you can do with show_all().
