This discussion is equivalent to the one that we just had. Read the thread "[PHP-DEV] Implicit isset/isempty check on short-ternary operator".
Also the "$var = var_set($_GET['var'], $_POST['var'], 'default');" syntax you propose would be equivalent to (as per previous discussion): $var = $_GET[?'var'] $: $_POST[?'var'] $: 'default'; (The syntax might also be [?'var'], ['var'?] or different).
