gmp_intval — Convert GMP number to integer
gmp_intval(GMP|int|string $num): int
This function converts GMP number into native PHP ints.
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).
The int value of num.
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
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().
