I never seem to be lucky enough to be sure of the type of data stored in a
php array, since php handles mixtures of types so forgivingly, and because
most of my data comes from forms, with users key in what they like,
including double and single quotes, parentheses (and especially commas, how
do you prevent breaking up your array and putting it back together with a
different row count because someone keyed in a comma?), etc. I would think
you would have to go to a lot of trouble to make sure that an array contains
only numeric data, or only strings that did not contain problem causing
characters.
You are right about more space being required for serialize, I often have to
resort to TEXT data types to provide enough space in the column for data
(65k runs out fast), and that is a bit slower as well.

Yes true, you can use serialize.
But since you know the format of your $array variable (which is simply
holding one data type) you can safely use split() and join()
better and smaller when stored in that field because they are comma
seperated.
