Putting the variable names are part of the item array data is very bad in my opinion. What I've done with more simple systems like that is set a serverr variable that show whats at each index:
serverr.itemvars_<typename>=id,qty,name,image,weig ht
clientr.item<number>=23,1,"Fancy Sword",fancysword.png,5000
Then you use function like getitemvar(id, varname) and return the item index that matches the index of the varname in the serverr string.

Edit: With the simplest system I would have the type of item as the first variable, then I would find the right variable list for that type with a function before continuing so all items didn't require a master list.
