)

)

求相同鍵名的值相加如(price 的相加結果) 數組條數不確定

------解決方案--------------------

$ar = Array(

'uid' => 19,

'pid' => Array (

0 => 91,

1 => 81,

),

'price' => Array (

0 => 6,

1 => 14,

),

'pnum' => Array (

0 => 1,

1 => 1,

),

);

$r = array_map(function($t) {

return is_array($t) ? array_sum($t) : $t;

}, $ar);

print_r($r);

Array

(

[uid] => 19

[pid] => 172

[price] => 20

[pnum] => 2

)

　　直接用foreach也可以。

$ar = Array(

'uid' => 19,

'pid' => Array (

0 => 91,

1 => 81,

),

'price' => Array (

0 => 6,

1 => 14,

),

'pnum' => Array (

0 => 1,

1 => 1,

),

);

foreach($ar as $k=>$v){

$arr[$k] = is_array($v) ? array_sum($v) : $v;

}

print_r($arr);
