I have a function that currently takes a boolean value as a parameter.
But now I want to expand it to 3 options... So if I have...
function doFooBar($doFoo = false)
{
if($doFoo)
{ echo "Did Foo"; }
else
{ echo "Did Bar"; }
}
Is it as "simple" as changing it like follows to avoid having to
change existing code that won't use the new values.
function doFooBar($doFoo = 0)
{
if($doFoo == 2)
{ echo "Did Baz"; }
else if($doFoo == 1)
{ echo "Did Foo"; }
else
{ echo "Did Bar"; }
}
Something about that disturbs me. Perhaps because any time I think "Oh
it will be as simple as..." it usually isn't.
Thanks in advance!

Unless you're doing a strict comparison (===), it probably won't make
a lot of difference. However, if you sent "true" to the function, I
believe it will reach the last else condition. You may revisit all the
locations you call it and update them appropriately.
Those are my initial thoughts....
