Is there anything that can make the returned length of the PHP CRC32 function to vary?
Thanks!
No, by definition a CRC32 has 32-bits.
You can only vary its representation. For instance, while it can be represented with 4 8-bit bytes (and hence fits in a PHP int), you may wish to represent that number in base 10 in a string, and then it can have 10 characters (unsigned), since 2^32-1 is 4294967295.
