$redis = new Redis ();
$redis->connect (' 127.0.0.1 ', 6379);
if (Empty ($argv [1])) echo "Please input your channel";
$channel = $argv [1]; Channel
$redis->subscribe (Array ($channel), ' callback ');
function callback ($instance, $channelName, $message) {
Echo $channelName, "==>", $message, Php_eol;
}

Release: publish.php

$redis = new Redis ();
$redis->connect (' 127.0.0.1 ', 6379);
/*argv[0] is the name of the file to execute, Argv[1] is the first parameter immediately following the execution of a file */
$channel = $argv [1]; Channel
$msg = $ARGV [2]; Msg
Var_dump ($channel. $msg);
$redis->publish ($channel, $msg);
