:: Tephlon PHP Persistence library :: For recent updates, documentation, examples, issue tracking and discussion please always refer to the following site: Feel free to contact me if you are interested in improving this software. == Install== Typically this is the directory layout you want to keep in your Tephlon project: Your_php_project_> |_> index.php |_> css/ |_> img/ |_> Tephlon == Direct Access Usage Example== // include somewhere Tephlon script appropriately. <?php require_once("/Tephlon/Tephlon.php"); // 1. Get a Tephlon persistent resource $t = Tephlon::getResource(); // 2. Decide a label for your precious object and invoke it with retrieve $my_precious = $t->retrieve("my_precious_label"); /* If there was a cache record for "my_precious_label", now the variable $my_precious will have its content inside. If no such record was found, it's being created with value of null, and null is returned. */ // You can also specify a fallback defaul value if the record is not found (optional) // $my_precious = $t->retrieve("my_precious_label", array()); /* Doing as above is the same of doing: $my_precious = $t->retrieve("my_precious_label"); if($myprecious != null){ $my_precious = array(); } */ // 3. Now you are free to modify your "precious" variable and make it become any type, from boolean to // any class object. Once you want to save it to Tephlon persistence layer, simply do: $my_precious = functionToCalculateImportantData($x, $y); // Other business logic... // 4. Saving to persistence! $t->register($my_precious, "my_precious_label"); // Now the new value of my precious will be saved, so that next script execution (read: page visit) will have that // content. // You can also specify a lifetime (in seconds) for this record. For example: // For example here, the content will be available for the next 24h $t->register($my_precious, "my_precious_label", 24*60*60); == Using TMap Data Structure == Note: refer to Twitter example and TMapTest.php for complete reference TMap is a wrapper class against the core I/O API of Tephlon's persistence engine. It works as Java's Map interface, implementing almost all methods: (get(key), put(key, value), clear(), values(), keys(), etc). but also a new one, which makes sense in PHP: getAll() which returns all the content of the map as an associative array. <?php // 1. include somewhere Tephlon script appropriately. require_once("/Tephlon/Tephlon.php"); // 2.a Initialize the TMap into global namespace. $map = new TMap(); // Now if you already executed the script, the map will already contain keys and values!!! // 2.b Initialize TMap specifying a namespace (some examples) $map = new TMap("myUsers"); $map = new TMap("posts_from_user_" . $userID); $map = new TMap("recent_comments"); // Now if you already executed the script, the map will already contain keys and values!!! /* NOTE: a namespace can set also passing an object, though this practice is quite risky since it can make your content unreachable if you do it wrong. */ // 3. Put some value (some examples) $map->put("key1", "some_string"); $map->put(time(), new Post($userID, $content); // 4. Modifying content of records $map->put("key1", "this_string_is_better"); // 5. Retrieve it $var = $map->get("key1"); $theUser = $map->get($requestedUser); $theUser->setEmail(""); $map->put($requestedUser, $theUser); Enjoy! Simone
