How to see if the passed numeric value of the variable lies between the values ​​of the array?

Question

PHP

The essence of the task is as follows:
The site has a slider that adjusts the price range and transmits 2 values, for example - "price from=1000" and "price to=2000",
in turn, these values ​​are elements, for example, of such an array:

$filters = [
    'Categories (xyz..)' => 'Обувь,Свадебная обувь по 1-ой паре',
    'Color' => ['белый', 'бежевый'],
    'Size' => '35',
    'Manufacturer' => 'кожзам',
    'Wholesale price' => [1000, 2000],
];

We have a two-dimensional array of such content, in which we will search for the specified price range:

array (size=22)
  'A072C02' => 
    array (size=2)
      1 => 
        array (size=67)
          'ID' => string 'A072C02' (length=7)
          'Wholesale price' => float 1404
          'Color' => string 'белый' (length=10)
          'Size' => float 35
          '' => null
      2 => 
        array (size=67)
          'ID' => string 'A072C02' (length=7)
          'Wholesale price' => float 2100
          'Color' => string 'белый' (length=10)
          'Size' => float 36 '' => null

So, the task is: if the price (Wholesale price) is not suitable, then we delete this internal element of the array (the 2nd, for example). Made the task as easy as possible. I would be grateful for the right direction of thought.

Answer 1

$range = [1000, 2000];
foreach($items as $key => $item) {
  $price = $item['price'];
  if ($price < $range[0] || $price > $range[1]) {
   unset($items[$key]);
  }
}

But if this array is selected from the base, then it's probably better to set it in the request.

Answer 2

This is a trivial task and is not done at the php level - it is done at the base level. Those. it is the task of the base to give the necessary selection, to form an array. Why else would SQL be needed at all?
