Question 2

Malaysian Identification Card (IC) number consists of 12 digits. Normally if the last digit is odd, then the card holder is a male. If the last digit is even, the card holder is female. Write a PHP code to accept the IC number and decide whether the input contains 12 digits. If it is not, display a message “IT IS NOT A VALID IC NUMBER”. If the number is valid, check the IC number whether it is odd or even. If it is even, display a message saying “CARD HOLDER IS A LADY”. If otherwise, then display a message saying “CARD HOLDER IS A GENTLEMAN”. An output example is shown in Figure 3.

Write the PHP code to solve the problem. Provide the HTML form in the answer.
