Exactly the same, why did it go wrong?

Question

<?php $arr=['Anhui','Wuhu','Anqing']; reset($arr); echo '<pre>'; print_r(echo($arr); echo '';

Answer 1

Brother, print_r ( echo ( $arr ) ), where are your brackets? You just wrote it blindly

Answer 2

Something must be wrong. Echo cannot output an array, right?
