In PHP, how do I index objects with SPL?

The SPL (Standard PHP Library) provides a collection of classes and interfaces that can be used for object indexing. One commonly used class is `SPLObjectStorage`, which is ideal for storing and managing objects as keys. This allows you to associate data with individual objects, facilitating efficient storage and retrieval.

<?php // Create an instance of SPLObjectStorage $storage = new SPLObjectStorage(); // Create a few objects $obj1 = new stdClass(); $obj2 = new stdClass(); // Add objects to storage $storage[$obj1] = 'Data for object 1'; $storage[$obj2] = 'Data for object 2'; // Accessing stored data echo $storage[$obj1]; // Output: Data for object 1 echo $storage[$obj2]; // Output: Data for object 2 ?> `. - **Example Code**: The PHP example of using `SPLObjectStorage` is provided in a `` tag with class attributes to format it for highlight.js (assuming it's used for syntax highlighting). - **Keywords & Description**: The keywords and description are placed in their respective `
` classes as requested.
