<?php $a = gmp_init("0xfd"); gmp_setbit($a, 1); // index starts at 0 echo gmp_strval($a) . "\n"; ?>
The above example will output:
255
Notes
Note:
Unlike most of the other GMP functions, gmp_setbit()
must be called with a GMP resource that already exists (using
gmp_init() for example). One will not be
automatically created.
