[php-src] Issue #14968: bug loop in php

Issue: https://github.com/php/php-src/issues/14968 Author: bsv-nhatha ### Description The following code: ```php <?php $value = [ ['a' =>'1', 'c' => '2'], ['a' =>'3', 'c' => '4'], ['a' =>'5', 'c' => '6'], ['a' =>'7', 'c' => '7'] ]; foreach ($value as $key => &$item) { $value[$key]['b'] = $item['a'] + $item['c']; } foreach ($value as $key => $item) { $value[$key]['a'] = $item['a']; } ``` Resulted in this output: ``` array:4 [ 0 => array:3 [ "a" => "1" "c" => "2" "b" => 3 ] 1 => array:3 [ "a" => "3" "c" => "4" "b" => 7 ] 2 => array:3 [ "a" => "5" "c" => "6" "b" => 11 ] 3 => & array:3 [ "a" => "5" "c" => "6" "b" => 11 ] ] ``` But I expected this output instead: ``` array:4 [ 0 => array:3 [ "a" => "1" "c" => "2" "b" => 3 ] 1 => array:3 [ "a" => "3" "c" => "4" "b" => 7 ] 2 => array:3 [ "a" => "5" "c" => "6" "b" => 11 ] 3 => & array:3 [ "a" => "7" "c" => "7" "b" => 14 ] ] ``` ### PHP Version PHP 8.2.20 ### Operating System MAC OS solana 14.5
