PHP Parsing Conundrum - "Missing Symbols Listed"

I am trying to access the Yahoo site by getting Stock quotes:

http://de.finance.yahoo.com/d/quotes.csv?s=^DJI&f=nsl1op&e=.csv

and it doesn't seem to be downloading any data. I get "Missing Symbols Listed.". Weird b/c this used to work!

<?php

function market_value($s) {

    $records= fopen ("http://quote.yahoo.com/d/quotes.csv?s=$s&f=nsl1&e=.csv");
    $contents = fread ($records);
    fclose ($records);

    $data = str_replace ("\"", "", $data);
    $data = expl开发者_StackOverflowode (",", $data);

    $trade= $data[2];

    return (".$trade.")";
}

^DJI can not be queried from yahoo, as it seems. You should use INDU. Try downloading

http://finance.yahoo.com/d/quotes.csv?s=INDU,GOOG,MSFT&f=nsl1op&e=.csv

This should return something like

"Dow Jones Industr","^DJI",12069.94,12057.34,12058.02
"Google Inc.","GOOG",601.74,600.06,600.76
"Microsoft Corpora","MSFT",26.13,26.10,26.16

Try getting the DJI quote from Googles HTML

This is an inefficient example in .NET C# (dont know php):

    public async Task<string> MakeGoogleDJIWebRequest()
    {
        string response = await _httpClient.GetStringAsync("http://www.google.com/finance?q=DJI");
        string [] myString = Regex.Split(response, "<span id=\"ref_983582_l\">");
        string [] myString2 = Regex.Split(myString[1], "</span>");
        string [] myString3 = Regex.Split(response, "ref_983582_c\">");
        string [] plusOrMinus = Regex.Split(myString3[1], "</span>");
        string DJI = myString2[0]+ " " + plusOrMinus[0];
        return DJI;
    }

If you just want the value of the DJI and not the +./- just dont add the plusOrMinus[0] above to the return string.
