[Mean]

Use [ pawn ] instead of [ php ]
Anyways, here is the fix:

pawn Код:

if(strcmp(cmd, "/say", true) == 0) 
{ 
    if ( !strlen( cmdtext ) ) 
        return SendClientMessage( playerid, COLOUR_ORANGE, "Usage: /say [text]" ); 
    new playername[ MAX_PLAYER_NAME ]; 
    GetPlayerName( playerid, playername, sizeof playername ); 
    new string[ 128 ]; 
    format( string, sizeof string, "**Admin [%s](id:%d): %s", playername, playerid, cmdtext ); // I changed this also
    return SendClientMessageToAll( COLOUR_RED, string ); 
}

I just changed strtok, since you don't need it in here.
