PHP - 如果数组数据符合条件，则在加载页面之前更改

Question

Variable $list stores an array like the one below.

Array
  (
    [0] => Array
       (
         [warehouse] => Array
            (
              [warehouseName] => Warehouse Europe
              [warehouseType] => en detail
            )

          [products] => Array
            (
               [0] => Array
                    (
                        [productName] => APPAREL SHIRTS
                        [productCode] => 54059761696
                        [measuringUnit] => buc
                        [quantity] => 1
                    )

                [1] => Array
                    (
                        [productName] => T-SHIRTS - SADAL
                        [productCode] => 54059764755
                        [measuringUnit] => buc
                        [quantity] => 0
                    )


  ........... more data ............

Using the following piece of code I print it on the display:

foreach($list as $item) {
    foreach($item['products'] as $product) {
        $wName = $item['warehouse']['warehouseName'];
        $wType = $item['warehouse']['warehouseType'];
        $pr =implode(',',$product);
        printf("%s,%s,%s".PHP_EOL,$wName,$wType,$pr);
    }
}

How can i search if quantity is more than 3, and if it meets the criteria than change it to ">2" before the information is passed to the browser?

Basically i need to keep the quantity confidential and only show ">2" if 3 or more products are retrieved from the array.

Thanks!

Answer 1

You can check whether the quantity is more than 2 and change the value you're going to display by using a ternary operator. So inside your inner foreach, before printing, you can do

$quantity = ($product['quantity'] > 2 ? '>2' : $product['quantity']);

Then you can print $quantity wherever you want it (as long as you're still inside your inner loop).
