Example 1

Working of gmp_and −

<?php
   $num1 = '4';
   $num2 = '8';
   $num3 = gmp_and($num1, $num2);
   echo "The BITWISE AND of 4 and 8 is :".$num3;

   echo "<br/><br/>";

   $num4 = '12';
   $num5 = '25';
   $num6 = gmp_and($num4, $num5);
   echo "The BITWISE AND 12 and 15 is :".$num6;
?>

This will produce following result −

The BITWISE AND of 4 and 8 is :0
The BITWISE AND 12 and 15 is :8

Example 2

Using GMP numbers −

<?php
   $num1 = gmp_init(4);
   $num2 = gmp_init(8);
   $num3 = gmp_and($num1, $num2);
   echo "The BITWISE AND of 4 and 8 is :".$num3;

   echo "<br/><br/>";

   $num4 = gmp_init(12);
   $num5 = gmp_init(25);
   $num6 = gmp_and($num4, $num5);
   echo "The BITWISE AND 12 and 15 is :".$num6;
?>

This will produce following result −

The BITWISE AND of 4 and 8 is :0
The BITWISE AND 12 and 15 is :8
