1002 total visitsThis class is designed to create bitmasks, which are very commonly used to store lists of true or false values as a single integer.The class can manpulate bitmasks that are not limited to 32 bits. It does not need the PHP gmp extension to provide arbitrary bit length support.This absence of limits may encourage the storage of more complex data ...
