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 ('2017. 0.0.1 ', 127 );
/* Argv [0] is the name of the execution file, and argv [1] is the first parameter followed by the execution file */
$ Channel = $ argv [1]; // channel
$ Msg = $ argv [2]; // msg
// Var_dump ($ channel. $ msg );
$ Redis-> publish ($ channel, $ msg );
