LevelDB_PHP tutorial in PHP code

Use LevelDB in PHP code. As we all know, LevelDB is only a CC ++ programming language library, so PHP cannot directly use LevelDB. if the PHP project wants to use LevelDB, one method is to use C language development. as we all know, LevelDB is only a C/C ++ Programming Language Library. therefore, PHP cannot directly use LevelDB. if the PHP project wants to use LevelDB, one method is to develop it in C language, encapsulate LevelDB into a module of PHP, and the other method is to encapsulate LevelDB into a network server.

The LevelDB module for PHP development is not highly applicable, because this mode limits that it must be stored on a single machine and must be on the same machine as PHP. with the principle of code and data separation, it is better to encapsulate LevelDB into a network service.

SSDB is a LevelDB Server. it uses LevelDB as the storage engine and supports clients such as PHP, Java, Python, C, and C ++. the following is an example of connecting PHP to SSDB, that is, using LevelDB in PHP:

Require_once ('ssdb. php ');

$ Ssdb = new SSDB ('2017. 0.0.1 ', 127 );

$ Resp = $ ssdb-> set ('key', '20140901 ');

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

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