Pls, I'm still stuck on this. I don't know how to check the last two numbers in my string if they end with two zeros. I was using strstr() but it wasn't it. I know jS could have been more appropriate but, I'm not good with jS. So, I'm opting for php The variable is $price = $_POST["pricetag"]; The user is to input a value & I want to check if it contains two zeros at the end cos that's what I want and if no two zeros, it should show error. But, how do I set the pointer to check the last two zeros in their price tags?
