Answer 1

You can try with one simple array map :)
$arr = [
'Total' => 21600000,
'Items' => [
'2-13' => [
'Item' => 2,
'PID' => 13,
'UPrice' => 11000000,
'Qty' => 1,
'Total' => 11000000
],
'58-167'=> [
'Item' => 58,
'PID' => 167,
'UPrice' => 5300000,
'Qty' => 1,
'Total' => 5300000
]
]
];
$test = array_map(function($ar) {
foreach($ar as $k=>$i) {
if( isset($i['PID']) && $i['PID'] == '13')
unset($ar[$k]);
}
return $ar; } , $arr);
var_dump($test);

You need 2 loop to do the action you want.
foreach($my_array as $key=>$value)
{
if(is_array($value))
{
foreach($value as $k=>$v)
{
if($k == 'PID')
{
unset($value[$k]);
}
}
}
}
with this you can remove only element with key PID.

Hi youre unsetting the $IOrder instead of the Item that you want to delete:
This code is a solution an i tested it :
$ShoppingBag = Array
(
"Total" => 21600000,
"Items" => Array
(
"2-13" => Array
(
"Item" => 2,
"PID" => 13,
"UPrice" => 11000000,
"Qty" => 1,
"Total" => 11000000,
),
"58-167" => Array
(
"Item" => 58,
"PID" => 167,
"UPrice" => 5300000,
"Qty" => 1,
"Total" => 5300000,
),
),
);
foreach($ShoppingBag["Items"] as $key => $value){
if($value["PID"]==13){
unset($ShoppingBag["Items"][$key]);
}
}
You should know that always when you're using foreach loop the foreach( $a as $b ) when you do something to $b , $a remains the same because tey are different variables :)
Hope it will help you .

$arr = [
'Total' => 21600000,
'Items' => [
'2-13' => [
'Item' => 2,
'PID' => 13,
'UPrice' => 11000000,
'Qty' => 1,
'Total' => 11000000
],
'58-167'=> [
'Item' => 58,
'PID' => 167,
'UPrice' => 5300000,
'Qty' => 1,
'Total' => 5300000
]
]
];
$pid_to_remove = 13;
$new_ar = array_filter(
$arr,
function ($v) using ($pid_to_remove) {
return (!isset($v['PID'])) || ($v['PID'] != $pid_to_remove);
}
);
