gmp_and — Bitwise AND

### Description

gmp_and(GMP|int|string `$num1`, GMP|int|string `$num2`): GMP

Calculates bitwise AND of two GMP numbers.

### Parameters

`num1`

  A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init() with automatic base detection (i.e. when `base` is equal to 0).

`num2`

  A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init() with automatic base detection (i.e. when `base` is equal to 0).

### Return Values

A GMP number representing the bitwise `AND` comparison.

### Examples

Example #1 gmp_and() example

`<?php
$and1 = gmp_and("0xfffffffff4", "0x4");
$and2 = gmp_and("0xfffffffff4", "0x8");
echo gmp_strval($and1) . "\n";
echo gmp_strval($and2) . "\n";
?>`

The above example will output:

    4
    0
