What are the advantages and disadvantages of using ksort and array_multisort functions in PHP for array sorting?
When sorting arrays in PHP, the ksort function is used to sort an array by key, while the array_multisort function is used to sort arrays by multiple keys or values. Advantages of using ksort: - Simple to use and effective for sorting arrays by keys. - Maintains the relationship between keys and values in the array. Disadvantages of using ksort: - Limited to sorting by keys only. - Not suitable for sorting by multiple keys or values. Advantages of using array_multisort: - Can sort arrays by multiple keys or values. - Allows for more complex sorting requirements. Disadvantages of using array_multisort: - More complex to use compared to ksort. - May require additional processing to handle sorting by multiple keys or values. PHP code snippet using ksort function:
$fruits = array("apple" => 3, "orange" => 2, "banana" => 1);
ksort($fruits);
print_r($fruits);
```
PHP code snippet using array_multisort function:
```php
$products = array(
array("name" => "Product A", "price" => 20),
array("name" => "Product B", "price" => 15),
array("name" => "Product C", "price" => 25)
);
// Sort by price
array_multisort(array_column($products, 'price'), SORT_ASC, $products);
print_r($products);
