How does this program work?
- This program is used to convert given Decimal number into equivalent of Hexadecimal number using PHP.
- That means convert number with base value 10 to base value 16.
- The integer entered by user will store in one variable. Divide that number by 16.
- Store the remainder when the number is divided by 2 in an array.
