Within the constructor for Randimg you could set a local protected

Hi Rich and all, just one other quick question...
Which approach below would you choose?
Example 1:
class Randimg {
# Initialize var variables:
var $foo1 = FALSE;
var $foo2 = FALSE;
var $foo3 = TRUE;
# Constructor:
function Randimg {
$this->foo1 = TRUE;
$this->foo2 = TRUE;
$this->foo3 = FALSE;
return $this->method_foo();
}
function method_foo() {
$x = $this->$foo1;
$y = $this->$foo2;
$z = $this->$foo3;
/* Do stuff... */
return $x.$y.$z;
}
}
Example 2:
class Randimg {
# Constructor:
function Randimg {
$foo1 = TRUE;
$foo2 = TRUE;
$foo3 = FALSE;
return $this->method_foo($foo1, $foo2, $foo3);
}
function method_foo($x, $y, $z) {
/* Do stuff... */
return $x.$y.$z;
}
}
Hopefully my syntax is decent... I am guessing the approach I take
depends on the needs of my script. Setting local protected variables
seems like it would work well for my latest project, but is that bad
programming practice to rely upon local protected variables when it
comes to passing variables between methods?
Seems like I have always read/heard that it is best to explicitly pass
variables as function parameters... vs throwing around "globals."
Sorry if silly questions. :)
Thanks again!
Cheers,
M
