Tutorial on using LevelDB_PHP in PHP code

As we all know, LevelDB is only a C/C++ programming language library, so PHP cannot directly use LevelDB. If a PHP project wants to use LevelDB, one way is to develop it in C language and encapsulate LevelDB into a module of PHP. One approach is to encapsulate LevelDB as a web server.

The way to develop PHP's LevelDB module is not very applicable, because this mode limits it to a single-machine storage and must be on the same machine as PHP. Under the principle of separation of code and data, LevelDB is encapsulated into a Online services are a better choice.

SSDB is a LevelDB server (LevelDB Server), using LevelDB as the storage engine, supporting clients such as PHP/Java/Python/C/C++. The following is an example of PHP connecting to SSDB, that is, PHP using LevelDB:

require_once('SSDB.php');

$ssdb = new SSDB('127.0.0.1', 8888);

$resp = $ssdb->set('key', '123');

$resp = $ssdb->get('key');

echo $resp->data; // output: 123

See the SSDB project Wiki for the complete API.
