How do you run raw redis commands in PHP? - php

Question

I have been using predis to try to figure out how to run raw redis commands, but I am having trouble. The documentation for predis is extremely outdated. It says that there is a method called "rawCommand()" which will allow a user to run raw Redis commands, but I found a changelog that says it is no longer supported:
https://github.com/nrk/predis/blame/master/CHANGELOG
Does anyone have any hints of how I can run raw redis commands?

Answer 1

Here you go. This has worked perfectly for me, and I did not know it even had that function
$cmdSet = $redis->createCommand('set');
$cmdSet->setArgumentsArray(array('library', 'predis'));
$cmdSetReply = $redis->executeCommand($cmdSet);
He has a wiki page on this. Look for sending commands.

Answer 2

I'm actually guessing here, but let's pretend for a while I did not say that aloud.
Check out the function writeCommand() in lib/Predis/Network/StreamConnection.php on line 176 and use it through SimpleDebuggableConnection in examples/SimpleDebuggableConnection.php. You still have to define new commands that are not already defined in lib/predis/commands, as mentioned in the wiki that #Colum referred to.
If you're really feeling adventurous, change the protected method writeBytes() in StreamConnection on line 96 to public. That should enable you to feed it pure redis with
$redis->getConnection()->writeBytes("*3\r\n$3\r\nSET\r\n$5\r\nmykey\r\n$7\r\nmyvalue\r\n")
Unfortunately, publicizing the writeBytes() seems to go in to the direction of http://en.wikipedia.org/wiki/Object_orgy anti-pattern.
Good luck!

Answer 3

It's easy!
Take this class: RedisServer
and write:
$redis = new \Jamm\Memory\RedisServer();
$redis->send_command('set','key',5); //here any raw command

Answer 4

PHPRedis
on phpredis extension you can use following:
$redis->rawCommand("count", "a:", 10, "a:");
PRedis
on phpredis you can use following:
$redis->executeRaw(["count", "a:", 10, "a:"]);
PRedis - more complicated way
on predis you can do like this:
<?php
require 'Predis/Autoloader.php';
Predis\Autoloader::register();
class PRredisCOUNT extends Predis\Command\Command {
function getId(){
return 'COUNT';
}
}
class PRredisSUM extends Predis\Command\Command {
function getId(){
return 'SUM';
}
}
function registerHM4Commands($redis){
$redis->getProfile()->defineCommand("count" , "PRredisCOUNT" );
$redis->getProfile()->defineCommand("sum" , "PRredisSUM" );
}
$redis = new Predis\Client("127.0.0.1:2000");
registerHM4Commands($redis);
// after that you can do:
$redis->count($key, $page, $prefix);
