Using indices 0 .. n make it possible to work with them like offsets
from the beginning of the array. More important from a C point of
view, where it may even improve performance. Ah, and for loops are
shorter by one character ;)
for ( $i=0; $i<$n; $i++ ) { .. }
rather than
for ( $i=1; $i<=$n; $i++ ) { ... }
