Several questions: How long can an index be in an associative array? (the indexes I use in this array are 32 character hashes)
As far as I know, it can be as big as your RAM will hold...
Can it start with a number (since a hash can start with a number)
Yes. A variable name cannot start with a number.
Can I use $index as an array name? (I do not remember off hand what the reserved key words are)
You can use '$index' if you want, sure. Thanks for the info;
