Unserialize functionality in ios??

[richammond]

Hi guys, i'm sure you all know the unserialze() function in PHP. I need the same thing for IOS. Basically i got a string from db field which looks like this :
a:4:{i:0;s:6:"Vincent";i:1;s:14:"Julie";i:2;s:12:" Tomas";i:3;s:10:"John";}

I would like the correct function to display the above string as : Vincent, Julie, Tomas, John.

I've looked into ios - Objective C: How to extract part of a String (e.g. start with '#') - Stack Overflow but didn't work out exactly as i wanted it :-(

Any help would be greatly appreciated.

Thanks!!

Not sure if there is a correct function but you may want to take a look at this post.

Hope this helps.

No, I don't know the PHP unserialze (unserialize?) command.

In general terms, it looks like a command that takes a variable (or object) and converts it to a byte-stream. That concept exists in Cocoa as well. However, the details are different. I doubt you'll find a ready-made way to unserialize PHP variables/objects into Objective C, since they are different languages, and their data structures and constructs are different. PHP is loosely typed, for example, which is likely to cause problems in creating Objective C equivalent structures.

You'll probably have to restrict what you put the DB fields in PHP to a specific format (or small set of possible formats), and then write Objective C code that parses that specific format into Objective C data containers.

Thanks!! Guess what i've done is as suggested : make sure the data being serialised is in a readable format. I wanted to go the quickest route, but seems like that one was the longest but simpler!!

Thanks again

It will probably be easier to export the data in a format like JSON that is cross-platform.

You could also use a PHP implementation of property lists, like CFPropertyList

Binary property lists are a whole lot faster and more efficient than text-based formats like JSON (or worse yet XML)
