i dissagree $this in a static object should point to the default
declared object,
and if that is unacceptable because u want the the default data to be
read only,
then it should be allowed for methods at least.
example
class lubas class
{
var $tbl = "";
var $fmt = 1;
function datfmt($d,$fmt) { return(""); }
function lufmt($db,$id,$fmt) {
$db->query("select * from " . $this->tbl . " where id=$id");
$db->next_record();
$this->datfmt($db->Record,$fmt); }
} // class
class lunam extends lubas
{
var tbl = "names";
var $fmt = 1;
function datfmt($arr,$fmt) {
return($arr["lname"] . "," . $arr["fname"]); }
}
right now the only way this class arrangments works is if the top class
gets allocated
but i belive that lunam::lufmt($db,1,1); should work every thing is
static
if class::data is not avalible and just class::method in static class
then
the static data could be written as a constant function
class lubas class
{
function tbl() { return(""); }
function datfmt($d,$fmt) { return(""); }
function lufmt($db,$id,$fmt) {
$db->query("select * from " . $this->tbl() . " where id=$id");
$db->next_record();
$this->datfmt($db->Record,$fmt); }
} // class
class lunam extends lubas
{
function tbl() { return("names"); }
function datfmt($arr,$fmt) {
return($arr["lname"] . "," . $arr["fname"]); }
}
but either way $this needs to be accessable in static functions or there
not wothless but not worth as much as they could and should be
right now i use this style of classes and dont like haveing to define a
global var, and declare it global evry where it gets used, when it is a
static class in evry sence of the word
just my 2 cents
