CakePHP选项：不确定此条目

Question

I have this in my options

a:4:{i:0;s:10:"Test";i:1;s:12:"FMy Files";i:2;s:7:"Walmen ";i:3;s:15:"Testing on the roof";}

How do I read or interpret it?

Does it floow have a certain criterion?

What is it called?

Answer 1

This is not JSON (notice the semicolons). This is serialized PHP data. You shouldn't have to do anything with it, and certainly not edit it (as you've obviously done, I guess to anonymise it): this is generated by PHP and should only be manipulated by the proper script. It contains metadata about itself, for data integrity checking, I think: Types and Lengths.
