Hi there ho there, this is probably going to be an easy one for you scripters.

I’m using functions in my pages and some of them have default values. However when I call the function (filling certain values but not others), php returns an error (saying it encountered unexpected ‘,’ or something).

This should be easier to understand:

```php

function anything($a,$b = 2,$c = 3, $d = 4){
 return ($a + $b + $c + $d);
}
//returns 10
echo anything(1);

//returns 16 
echo anything(1,3,5,7);

//returns a friggin error
echo anything(1,,,7);

```

How can I tell PHP that I want these two values to be the default ones declared in the function ?

cheers
