Why don't you just make the extra parameters optional? As in: function test1($test, $this=NULL) { if (isset($this)): echo "\$this was passed with value $this"; else: echo "\$this was not passed"; endif; } > function test2($arr) > { > extract($arr); > print $this; > } > > test2($arr = array( > "test" => 1, > "this" => 2 > )); > // output > 2 > > is there another ... better or cleaner way? If you want "named" parameters, this is pretty much how to go about it -- except that the function call doesn't need the "$arr =", so could be written more cleanly as: test2( array('test'=>1, 'this'=>2) ); Cheers!
