If it is a dot then answer 32 If it is a comma then answer 16 > echo strlen(md5(rand(). TRUE)); 32 > echo strlen(md5(rand(), TRUE)); 16

Also, the second parameter Refers hex or binary output format, Returns raw 16-bit binary format if raw_output sets TRUE and return 32-bit hex format for setting FALSE (default). If a comma would have been written instead of the dot, then 16 would have been the answer.
