gmp_intval — Convert GMP number to integer

### Description

gmp_intval(GMP|int|string `$num`): int

This function converts GMP number into native PHP ints.

### Parameters

`num`

  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

The int value of `num`.

### Examples

Example #1 gmp_intval() example

`<?php
// displays correct result
echo gmp_intval("2147483647") . "\n";
// displays wrong result, above PHP integer limit
echo gmp_intval("2147483648") . "\n";
// displays correct result
echo gmp_strval("2147483648") . "\n";
?>`

The above example will output:

    2147483647
    2147483647
    2147483648

### Notes

Warning

This function returns a useful result only if the number actually fits the PHP integer (i.e., signed long type). To simply print the GMP number, use gmp_strval().
