default argument values

[Nikola Skoric]

Hi there, is something like this possible in PHP:

function foo($a=1, $b=2, $c=3) {
//...
}

foo($b=2);

Will this assign $a and $c to default values?

only
function foo($b=2,$a=1, $c=3) {
}

foo(2);

Unfortunately it doesn't work that way. The default is only taken when
the argument is not specified at all and I don't think you can name the
parameters like that when you call the function. The best you can do
is something like this:

function foo($a = 1, $b = 2, $c = 3) {
//do something
}

//Is valid, $a = 5, $b = 2, $c = 3
foo(5);

//Is valid, $a = 5, $b = 42, $c = 3
foo(5, 42);

//Syntactically valid, but results in $a = 5, $b = 2, and $c = 3
inside the function.
//Basically assign 5 to $b (outside the function) then pass the result
(5) as the first
//parameter to foo():
foo($b = 5);

No.
