I need to store lots of two-dimensional arrays inside database and was not sure what to use:
implode. So I did a few tests, to find out which one is working faster and came to the conclusion it was
Execution times: 1'000'000 Serialize: 1.4974119663239 seconds Implode: 2.5333571434021 seconds Explode: 4.0185871124268 seconds Unserialize: 1.6835169792175 seconds
So the question: Why is implode+explode so much slower then serialize+unserialize?
PS: I found this question already, but it is not exactly what I am asking.
My idea is that
implode operate on strings that’s why, while
unserialize output/input a string at the very ending/beginning. Probably the more strings you
implode and the longer string you
explode, the slower it is, have you tried?
Which to use I don’t know, it depends if you later wish to handle output string, I think
serialized string is more difficult to parse. But to store it in database or file I’d use
