How to Sort an Associative Array by Column Value in PHP?

How Can I Sort an Associative Array By Column Value?

This task requires employing the array_multisort() function, which can sort multidimensional arrays. To sort an array of associative arrays by a specific column value, such as "price," follow these steps:

1. Extract the values from the desired column into a separate array:

   $price = array();
   foreach ($inventory as $key => $row)
   {
    $price[$key] = $row['price'];
   }

2. Call array_multisort() to sort the columns:

   array_multisort($price, SORT_DESC, $inventory);

Alternatively, you can use array_column() in PHP 5.5.0 and later to extract the column values:

$price = array_column($inventory, 'price');

array_multisort($price, SORT_DESC, $inventory);

By following these steps, you can efficiently sort an array of associative arrays by the specified column value.
