The following php example helps you to get the list of prime numbers from the given range.
Code Example:
<?php $num1 = 2; $num2 = 100; $col = 0; echo "<h1>List of prime numbers from $num1 to $num2 </h1>"; echo '<table width="60%" border="1"><tr>'; foreach ( Prime ( $num1, $num2 ) as $item ) { if ($col >= 10) { echo '</tr><tr>'; $col = 0; } echo "<td> $item </td>"; $col ++; } echo '</tr></table>'; function Prime($num1, $num2) { $prime_numbers = array (); while ( $num1 < $num2 ) { $isprime=true; for($i = 2; $i <= sqrt ( $num1 ); $i ++) { if ($num1 % $i == 0) $isprime=false; } if ( $isprime ) { $prime_numbers [] = $num1; } $num1 ++; } return $prime_numbers; } ?>
Output:
List of prime numbers from 2 to 100 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
