Array problems

[DustyPorViva]

I'm working with arrays and having a bit of problems:

PHP Code:

echo(this.itemdb.(@temp.list[i])); 


Echoes:

Checking inventory...
{vs_icon-arrow.png,Weapons,6,0,Traditional arrows crafted for efficient archery}
{wbomb1.png,Weapons,6,0,An explosive fuse bomb}
{wboom0.png,Weapons,6,0,Deadly weapon, crafted to always return}
{wbowi1.png,Weapons,6,0,A simple wooden bow}
{wham1.png,Tools,6,0,Hammer capable of breaking small rocks}

But...

PHP Code:

echo(this.itemdb.(@temp.list[i])[0]); 


Echoes the same exact thing, not the subarray. Any idea what I'm doing wrong?
