How can I read the previous value in a loop?

For example I have

{ section name="foo" loop="$somecounter"}
. 
.
.
{ /section}

But in the section loop, I want check the current value of an array item against the previous. I tried this:

{ section name="foo" loop="$someCounter"}
. 
{ if $variable[someCounter] = $variable[someCounter - 1]
 then do this
{ else}
 do this
{ /if}
.
.
{ /section}

But adding the -1 seems to break the php. Can anyone help?

Thanks,
