add variable into function

[jaymc]

Lets say I have a function set out like this

 

function beans($a,$b) {
  // DO STUFF
}

 

I have used this 100's of times in various scripts.. however, I now need to change this function to look like

 

function beans($a,$b,$c) {
  // DO STUFF
}

 

 

Is there a way to call the function like beans($a,$b) or beans($a,$b,$c) so that if $c is not used it is simple ignored, as apposed to javascript giving an error

 

I do not want to change all occurances of this function if I do not have to

 

Thank you!

PHP does it like this

 

function myFunction($mandatory_argument,$optional_argument = 1) {

/* ...Whatever... */

}
