PHP CRC32 length output

Question

Is there anything that can make the returned length of the PHP CRC32 function to vary?

Thanks!

It might help to explain why you want to do that? Perhaps you're asking the wrong question? — Paul Dixon, May 23 '10 at 19:42
Storing the data, i want to make sure that a CRC32 always fits in a INT field, for eg. — Industrial, May 28 '10 at 16:45

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.
