For example, what if I had a script that I ran from the command line that edited xml files that were more than 3 gigabytes in size? Lets assume that this was the only way to get this data, and this script was putting the data in a database. I would not be able to do that operation in 32 bit php because the entire xml file could not be loaded into memory. The above example is more feasible then many would think (sometimes you have no control over the format of the data you get). There are also other cases where the memory address limitations of a 32 bit process could come into play. Justin
