Get rest of var name

[sssssssssss]

I was wondering if you have a variable like

PHP Code:

bids.sssssssssss.Weapons.Decus_Arillias.BigSword 


if there is a way, kind of like using

PHP Code:

getdynamicvarnames() 


but instead if i say something like

PHP Code:

this.bids.temp.acct.something here 


to get the rest of the variable and save it as a

PHP Code:

temp.var =  .Weapons.Decus_Arillias.BigSword 


?
(hope this makes sense).
