I found it much faster to spit out an array declaration and then use eval() to pull that data back in. I had about 500kb of data.

I don't exactly get what you said there... Like : $serialized = 'array(' . implode(',',$my_array) . ');'; And then : $unserialized = eval($serialized); ? Anyway, that kind of stuff wouldn't work very well in my case. Check the array structure XML_Indexing uses for storing index. It is far from a 2D thing. The following example is an index for all occurences of RDF:Description tags which contain a 'test' attribute, in a 2.5 Mb RDF file. Each of these occurences consists in a couple : the XML region offset (as used when calling fseek()) and its length. (sorry for so much pasting, but that is a real example) Array (
