數組求和操作,該怎麼處理

數組求和操作

foreach($a as $k=>$v)
{
print_r($newarr);
echo $a[$k]['5'].'
';
}

Array
(
    [0] => Array
        (
            [lotno] => 3206
            [count] => 12
        )

    [1] => Array
        (
            [lotno] => 3207
            [count] => 63
        )

    [2] => Array
        (
            [lotno] => 3218
            [count] => 180
        )

)
120
Array
(
    [0] => Array
        (
            [lotno] => 3206
            [count] => 12
        )

    [1] => Array
        (
            [lotno] => 3207
            [count] => 63
        )

    [2] => Array
        (
            [lotno] => 3218
            [count] => 180
        )

)
135

將count相加，如果對應行的結果為120，則顯示3206*12 3207*63 3218*45
若對應行的結果為135，則顯示3218*135 (135=180-45(上一輪count已用的45)，不夠則補齊)

------解決方案--------------------
這個意思

$ar = array (
array( 'lotno' => 3206, 'count' => 12 ),
array( 'lotno' => 3207, 'count' => 63 ),
array( 'lotno' => 3218, 'count' => 180 ),
);

$s = '';
$n = 0;
foreach($ar as $r) {
  if($n + $r['count'] > 120) {
    echo $s . $r['lotno'] . '*' . (120-$n) ."\n";
    echo $r['lotno'] . '*' . ($n = $r['count'] - (120-$n)) ."\n";
