SendCustomPlayerMessage(playerid, color, text[])
{
    if(strlen(text) > 64)
    {
        new text1[65],
            text2[65];
            
        strmid(text2, text, 64, 128);
        strmid(text1, text, 0, 64);
                
        format(string, 128, "%s...", text1);
        SendClientMessage(playerid, color, string);
        
        format(string, 128, "...%s", text2);
        SendClientMessage(playerid, color, string);
    }
    else SendClientMessage(playerid, color, text);
}

Ex:
SendCustomPlayerMessage(0, 0xAA3333AA, "Sam says: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaa");

Will output

Sam says: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaa...
...aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaa
