Optional Arguyments for User defined functions

[asuamol]

How Do i put optional arguments( not the default) in PHP functions?

🙂

I believe u can just put them in your function definition without a default.
Just make their use optional.

if (isset($optional_var)) ......

hehe, asuamol, you dislike the idea of using (possibly empty) array of optional arguments, as i suggested a while ago? 🙂

[mrmufin]

function SomeFunction($a, $b='', $c=1) {
}

In the above function the variable $a is required, $b is optional, and will use '' when the function is not called with a value, and $c is optional and will use '1' as a default.

It's best to put optional arguments as the last argument(s) in your function.
