gmp_or — Bitwise OR

### Description

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

Calculates bitwise inclusive OR 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 object.

### Examples

Example #1 gmp_or() example

`<?php
$or1 = gmp_or("0xfffffff2", "4");
echo gmp_strval($or1, 16) . "\n";
$or2 = gmp_or("0xfffffff2", "2");
echo gmp_strval($or2, 16) . "\n";
?>`

The above example will output:

    fffffff6
    fffffff2
