Question

I want to execute this statement

$Data=$cash-$tax

The problem is that the tax differs for various ranges of cash

exactly as shown below.

cash range ————> tax

5,000 – 30,000——–> 700

30,001- 60,000——– > 1,000

60,001 – 125,000 ——-> 1,600

125,001 – 250,000 ———> 3,000

250,001 – 500,000 ——– > 5,000

500,001 – 1,000,000———> 9,000

what code can i use to explain this. Ive tried if else

if($cash >=0 && <=30000) $tax=700;
elseif($cash >=30001 && <=60000) $tax=1000;
elseif($cash >=60001 && <=125000) $tax=1600;
elseif($cash >=125001 && <=250000) $tax=3000;
elseif($cash >=250001 && <=500000) $tax=5000;
else($cash >=500001 && <=1000000) $tax=9000;
endif

This is not working i dont know where the problem is.

Answer 1

You need the full comparison expression for every item.

You can’t do if (($cash > 20) && (< 50)). $cash must be part of every expression:

if($cash >=0 && $cash <=30000) $tax=700;
elseif($cash >=30001 && $cash <=60000) $tax=1000;
elseif($cash >=60001 && $cash <=125000) $tax=1600;
elseif($cash >=125001 && $cash <=250000) $tax=3000;
elseif($cash >=250001 && $cash <=500000) $tax=5000;
else($cash >=500001 &&$cash  <=1000000) $tax=9000;
endif

This gets really fun if you try to apply the same logic in Delete queries:

DELETE FROM users WHERE id = 1 OR 2;

Where did all my users go?
