[UltraScripter]

Use sscanf+izcmd
Izcmd: https://www.******.co.il/search?q=iz...T0BIXfUe6ZqMAM
Sscanf2: https://sampforum.blast.hk/showthread.php?tid=570927

PHP код:

CMD:say(playerid, params)
{
     new str[128];
     if(sscanf(params, "s", str)) return SendClientMessage(playerid, color, "usage /say [text]");
     SendClientMessageToAllcolor, str);
     Return 1;
} 


That's easier than strcmp and start ok isn't it?
