How to print prime numbers in php? Does anyone know the formulas/syntax ?

Answer 1

jung1999 , you can check whether any number is divisible by anything starting from 2 to number (infact square root of number) or not... if it is divisible, number is prime.

For example , you want to check number 6 as prime, try to divide it from 2 to 5 and as it's divisible by 2 , it's not prime..
as 7 is not divisible by 2 to 6, it's prime...

note that 1 is not prime number
