To working string#
- from_int(int $value, int $sizeof) string#
Imports a regular PHP int.
- Parameters
$value (
int) – The value. Negative values are accepted but they will be cast to unsigned$sizeof (
int) – Length of the unsigned number in bytes.
- Returns
Binary string in the form this library accepts
If
$sizeof <= PHP_INT_SIZE, value may be truncated. (but do you really need this lib then?)
- from_hex(string $value, int $sizeof) string#
Imports a number written as a hexadecimal string.
- Parameters
$value (
int) – String of hex digits$sizeof (
int) – Length of the unsigned number in bytes
- Returns
Binary string in the form this library accepts
If
strlen($value) >= $sizeof * 2, value may be truncated.
