PS -- this sort of thing is generally unsafe, as you've not checked that
the returned array even *has* an element with index 0. someFunctionCall
might be defined as:

function someFunctionCall ()
{
if (some error condition)
return FALSE;
else
return array(etc, etc, etc);
}

You should really check that someFunctionCall has returned an array, and
that the array has an element 0 before you try to print element 0 out!
