    # Write a program in php to print prime numbers between 1 and 100

Print prime numbers from 1 to 100 in PHP using for loop and while loop.

In this article, you will learn how to print prime numbers from 1 to 100 in PHP using for loop and while loop.

### Example

------The prime numbers from 1 to 60 are------

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59

You should have the knowledge of the following topics in PHP programming to understand this program:

• PHP For loop
• PHP While loop

### Sample of Prime Numbers

2 3 5 7 .......... 47 53 59

1. Using the for loop
2. Using the while loop

Run Program

### Output

`------The prime numbers from 1 to 60 are------`

`2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 `

### Explanation

In this given program, we have taken input in the variable `\$x = 60` to generate the prime numbers up to 60.

Then we applied simple calculation via for loop to check every number of range between 1-60 to find the prime numbers.

If any number is divided by only 1 & itself and which number is divisible by any numbers it means these type numbers are called the prime numbers.

After the whole calculation, this will return these numbers:  `2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59`, It's the final output of the above program.

Run Program

This blog describes how to find prime numbers between 1 and 100 using PHP. Prime number is a number which is divided by 1 and itself.  Consider the number 5. It is prime number because it can be divided by 1 and 5.

### PHP program for prime numbers:

Consider the below program which is used to find prime numbers from 1 to 100.

for(\$i = 1; \$i <= 100; \$i++)
\$mm = 0;
for(\$j = 2; \$j <= \$i/2; \$j++) {
//only not prime numbers
if (\$i % \$j == 0) {
\$mm++;
break;
}
}
if (\$mm == 0) {
echo"\$i is prime number
";
}
}
?>

In above program, if a number is divided by any number except 1 and itself, then it is not prime number. Otherwise it is a prime number.

Now you got prime numbers between 1 and 100 using PHP.
