He may also consider the position of the inc/decrementor.
Example (note that the first element of an array has index 0):
$a = Array(1,2,3,4,5);
$i = 1;
executing
echo $a[++$i]
will output
3 2
echo $a[$i++]
will output
2 2
In both cases $i gets incremented, but the value used to access the
array might be before or after the increment takes place, according to
the incrementor (or decrementor, if you use --) position. A subtle, but
often very handy nuance.
