function parameter question

[petermichaux@yahoo.com]

Hi,

What does the "=array()" mean? It works with or without it in PHP5. The
code was written for pre-PHP5.

public function getPhrase($a_st Name, $a_astValues = array())

Thanks,
Peter

A question: what is the "public" qualifier for? I know what it means in
Java but I haven't seem it used in PHP before.

public is for php5 class methods. They can also be private or
protected.

Maybe I figured out my question. Does "= array()" simply create an
default empty array if a second parameter is not supplied in the call
to the method?

bingo.

same as

function doit ($x=11) {
//do stuff with $x
}

will give $x a default of 11 if the parameter is not supplied in the call
to the function....
