user defined functions with optional arguments?

[Exyle]

I have a function that has two arguents, however depending on the value
of the first argument, the second one may or may not be needed. If I
only input the first argument when calling the function, PHP returns a
warning. many built in php functions have optional arguments, is there a
way to make arguments in user defined functions optional as well?

Thanks.

You have to give the second argument a default value

function foo($arg1,$arg2 =NULL)

then the function can be called without $arg2

hih
