如何使用php连接到redis但不使用客户端库

Question

I'd like know what is the way to connect to redis using php from scratch (without use a client like predis)?

Thanks.

Answer 1

You can connect by using fsockopen and communicate by sending raw commands and reading server response:

$c = fsockopen('127.0.0.1', 6379, $errCode, $errStr);

$rawCommand = "*2
\$4
Echo
\$12
hello world!
";

fwrite($c, $rawCommand);

$rawResponse = fgets($c);
echo $rawResponse; // $12

$rawResponse = fgets($c);
echo $rawResponse; // hello world!

To use it this way, you should get familiar with Redis protocol: http://redis.io/topics/protocol
