Two optional arguements

[vitalyb]

    <?php 

function func($a = 5, $b = 6)
{
	echo "HI!<br>";    
}

?>

I'd like to run the following function by inserting only the second optional arguement. Something like:
func(, 8);
Is it possible?

Without changing arguments order - no, I think.

Note that when using default arguments, any defaults should be on the right side of any non-default arguments; otherwise, things will not work as expected.

Unfortunately, you can't do what you're asking...

Think about maybe making the function default to something if you supply it with a 'special' value or something. So if you call myFunctoin with arguement A as the string 'DEFAULT' it will use some default value or something...

or, to elaborate on what tserbis said, swap the vars

function func($b = 6, $a = 5) 
{ 
echo "HI!<br>";     

}

//then you can call
func($b = 1);
// and $a will default to 5

the vars which default always have to be to the right - you cannot skip an argument just by putting in an extra comma
