Question 43/69
How can you recover the original information from this string?
```
a:4:{i:2;s:3:"foo";i:3;s:4:"spot";i:4;s:6:"stripe";s:3:"bar";i:64;}
```
using json_decode()

using the mcrypt extension

using unserialize()

using a database library

you can't – this is a custom format

This data is PHP's serialized format so you wamt to unserialize it – it does look a bit like JSON, but the clue is that the example here includes information about the data type, which JSON does not.
