No, it can't. It is, in fact as you stated, the way dinosaurus' used to
code. That's why they are now extinct.
How ever, you've not provided enough information about what's inside the if
statememnts, to give a perfect answer. as soon as you describe a little more
about what's inside your if segments, there's no way to give you a decent
answer. What I can tell you right now is that you can evaluate the if's as a
number, and call a corresponding funtion.
I'd think the variables as a number:
$binary = (int)($a==a) . (int)($b==a) . (int)($c==a) . ... . (int)($j==a);
$number = bin2dec($binary);
Now $number is a numeral representation of the states of the variables. Now
you have a numbered function for each of the cases, named toDo_xxx() where
xxx is the corresponding number.
You call the function with a method called variable function. We form the
name of the function:
$todo_func = "toDo_$number"; // now $todo_func contains the name of the
function to be called.
now just callthe function via the variable.
$todo_func(); //Hands up, who knew that you can call a
// function with a variable that contains the name of the function?
By this you save the processor from not doing a gazillion if operations, you
simply jump to the function you want to call.
This is still not the final solution, since it still require a gazillion
functions. The true answer is to split the problem into the actual ten items
you have. You need to find a way to split the problem into:
if($a==a) {
// do AA thing
} else {
// do aa thing
}
if($b==b) {
// do BB thing
} else {
// do bb thing
}
..
..
..
if($j==j) {
// do JJ thing
} else {
// do jj thing
}
Where you now instead of 3k+ lines have actually just 20 or so. But as I
said, we'd need to know more about the nature of what is done inside each
if, to suggest a more logical way. In human-dinosaurus scale, what I've
offered you is still just a dinosaur who has learned to seek shelter from
rain.
Insufficient data...
