<?php $a = gmp_init("0xff"); gmp_clrbit($a, 0); // index starts at 0, least significant bit echo gmp_strval($a) . "\n"; ?>
The above example will output:
254
Notes
Note:
Unlike most of the other GMP functions, gmp_clrbit()
must be called with a GMP resource that already exists (using
gmp_init() for example). One will not be
automatically created.
