$fruits = array("apple", "banana", "orange", "pear"); $fruit = get_item("banana", $fruits); echo $fruit; // output: bananaIn this example, the get_item function is used to retrieve the item "banana" from the $fruits array. The output will be "banana". It is difficult to determine the package library that includes the get_item function as it may be a custom function created by the developer. However, it is a commonly used function in many PHP frameworks and libraries.
