# Find prime numbers between 1 and 100 in PHP

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.

<?php
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<br/>";
}
}
?>

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.
