using array_intersect() without keeyping keys from the array1, i.e. re-number intersect array keys.

hello all,

I only use indexed arrays.

When I use array_intersect function, of $a3 = array_intersect( $a1,
$a2 ), I just need the vales of intersect array and let keys to be
re-numberred from 0.;

I found the intersect array $a3 have the correct values but keep the
keys of $a1. When I use
for loop from $index=0 to sizeof ($a3)-1, by $a3[$index], php reports
"undefined offset " problem.

How can I re-number the keys of $a3 from 0 to sizeof($a3)-1;

Thans.
