class Person { public $name; public $age; public function __construct($name, $age) { $this->name = $name; $this->age = $age; } } // Creating a list of people $people = [ new Person("John", 28), new Person("Mary", 21), new Person("Tom", 35), new Person("Jane", 30), new Person("Bob", 24), ]; // Searching for a person by name $searched_person = array_search('Bob', array_column($people, 'name')); // Displaying searched person's age echo $people[$searched_person]->age;In this example, we have a Person class with two properties: name and age. We create a list of people, and then we use the array_search and array_column functions to search for the person with the name "Bob". Once we find that person, we display their age. The PHP Object find method is not part of any specific package or library. It is a basic function of PHP itself, and can be used in any PHP project.
