In PHP, how do I cache objects in vanilla PHP?

In vanilla PHP, you can cache objects using various strategies. One common method is to use file-based caching, where you serialize the object and store it in a file for later retrieval. This improves performance by reducing the need to recreate the object every time it's needed. Here’s a simple example of how to implement caching in PHP.


        <?php
        // Caching function
        function cacheObject($key, $object) {
            $cacheFile = __DIR__ . '/cache/' . md5($key) . '.cache';
            file_put_contents($cacheFile, serialize($object));
        }

        // Retrieving cached object
        function getCachedObject($key) {
            $cacheFile = __DIR__ . '/cache/' . md5($key) . '.cache';
            if (file_exists($cacheFile)) {
                return unserialize(file_get_contents($cacheFile));
            }
            return null;
        }

        // Example object
        class SampleObject {
            public $name;
            public $value;

            public function __construct($name, $value) {
                $this->name = $name;
                $this->value = $value;
            }
        }

        // Usage
        $obj = new SampleObject('Test', 123);
        cacheObject('sample_key', $obj);

        $cachedObj = getCachedObject('sample_key');
        if ($cachedObj) {
            echo "Object restored from cache: " . $cachedObj->name . " with value " . $cachedObj->value;
        } else {
            echo "No cached object found.";
        }
        ?>
