...just use the version of PrintToChatAll that exists in the SourceMod API.

Edit: If you really want to know what the code for PrintToChatAll looks like:

PHP Code:

stock void PrintToChatAll(const char[] format, any ...)
{
    char buffer[254];
    
    for (int i = 1; i <= MaxClients; i++)
    {
        if (IsClientInGame(i))
        {
            SetGlobalTransTarget(i);
            VFormat(buffer, sizeof(buffer), format, 2);
            PrintToChat(i, "%s", buffer);
        }
    }
}
