How can I delete a subArray, if search values matches? - php

Question

I am fairly new to working with arrays and I am stuck on being able to delete an entry.
If I have:
$del_itemid = 58;
$del_modiifier = 1;
How do I search through my array $orders and unset the array containing these variables ?
$orders = Array
(
[0] => Array
(
[itemid] => 67
[modifier] => 1
[quantity] => 1
[unit_price] => 17.00
[categoryid] => 2
)
[1] => Array
(
[itemid] => 58
[modifier] => 1
[quantity] => 1
[unit_price] => 18.00
[categoryid] => 5
)
[2] => Array
(
[itemid] => 72
[modifier] => 1
[quantity] => 1
[unit_price] => 10.00
[categoryid] => 3
)
)
EDIT:
This is what I have been trying:
$i = 0;
foreach($orders as $key => $value) {
$itemid = $value['itemid'];
$modifier = $value['modifier'];
if ($itemid == $del_itemid && $modifier == $del_modifier) {
unset($_SESSION['cart'][$i]);
break;
}
$i++;
}

Answer 1

Since you want to check 2 values, I would use array_filter() to loop through the array and filter all subArrays out, where both values are equal to your search values, e.g.
$newArray = array_filter($orders, function($v)use($del_itemid, $del_modiifier){
if($v["itemid"] == $del_itemid && $v["modifier"] == $del_modiifier)
return FALSE;
return TRUE;
});

I found a solution based on what I was originally trying to achieve with the loop. If I use array_splice() instead of unset() it will reset the index so that it remains possible to loop through the array without there being holes in the index:
$i = 0;
foreach($orders as $key => $value) {
$itemid = $value['itemid'];
$modifier = $value['modifier'];
if ($itemid == $del_itemid && $modifier == $del_modifier) {
array_splice($orders, $i,1);
}
$i++;
}
