I have 4 files index.php, Database.php, Zoo.php, Animal.php
// Zoo.php
class Zoo {
private $db;
private $animals = array();
public function __constructor(Database $db) {
$this->db = $db;
$this->getAllAnimals();
}
private function getAllAnimals() {
//Database stuff, returns an array with all animals
$p=0;
foreach($dbresult as $an){
$animals[$p++] = new Animal($an['name'], $an['age'], $an['weight']);
}
}
public function listAnimals() {
foreach ($this->animals as $a){
echo $a->name;
//and so on
}
}
}
// Animal.php
class Animal {
// variables for the animals
}
// index.php
<?php
include 'Database.php';
include 'Zoo.php';
$db = new Database();
$zoo = new Zoo($db);
$zoo->listAnimals();
?>
This is from the top of my head, so if there are some errors, just treat it as pseudocode :)
My problem:
I get a Fatal Error Class Animal not found.
If I add include 'Animal.php'; in the first line of Zoo.php, right before class Zoo { it works.
I'm stil learning about OOP with php, and the include-line strikes me as odd, so I ask for someone to help me out with this.
Is there another way to use "Animal"-objects in the "Zoo"-class, without the include or is it normal to use include, or maybe require/require_once?
