<?php // Create a new SPLObjectStorage instance $objectStorage = new SPLObjectStorage(); // Create some objects to cache class MyObject { public $id; public function __construct($id) { $this->id = $id; } } // Instantiate objects $obj1 = new MyObject(1); $obj2 = new MyObject(2); // Store objects in SPLObjectStorage $objectStorage[$obj1] = "Object 1"; $objectStorage[$obj2] = "Object 2"; // Retrieve and display cached objects foreach ($objectStorage as $obj) { echo "Key: " . $objectStorage[$obj] . " - ID: " . $obj->id . "<br>"; } ?>
