PHP two-dimensional array identical key name add

PHP two-dimensional array same key name add

Array

(

[UID] => 19

[PID] => Array

(

[0] => 91

[1] => 81

)

[Price] => Array

(

[0] => 6

[1] => 14

)

[Pnum] => Array

(

[0] => 1

[1] => 1

)

)

To find the value of the same key name as the sum of the values (price added) the number of array bars is indeterminate

------Solution--------------------

$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

)

------Solution--------------------

You can also use foreach directly.

$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);
