Hi,
I'm having here a problem with a function that uses default values. I declared a function like this:

PHP Code:

function _subtractresources($townid, $towntype, $wood = 0, $stone = 0, $metal = 0) { 


As you can see I am using default values on the last three arguments.
Now how can I run the functions while, for example, only putting the townid, towntype and stone arguments? I tried something like this...

PHP Code:

_subtractresources($idtown, $typetown, , 300, ) 


I thought of it because you could also do it on a for(;$x < 5; ) .
But it doesn't works, also if I erase the last comma ' , '. Instead I get something like: Parse error: syntax error, unexpected ',' in C:\My\Path\To\It\some_file.php on line 89.
Can anyone tell me on how to do it? In the last case I fill in all the blank spaces with 0.

Thanks in advance,

PHP Code:

_subtractresources($idtown, $typetown, 0, 300); 


You just have to enter in the default value for any skipped parameters.

sure, thanks for the info.

You may also create wrapper functions for each resource type and call your existing function from it with right arguments:

PHP Code:

function subtract_wood($town_id, $town_type, $value) {
   _subtractresources($town_id, $town_type, $value);
}
function subtract_stone($town_id, $town_type, $value) {
   _subtractresources($town_id, $town_type, 0, $value);
}
