RE: [PHP] Str_Replace Command
Matt:
This worked perfect. Thank you. I didn't realize it was reassigning, I
thought it would work similar to array_push and add to the existing data. I
get it now, thanks to you.
Thanks again. I had been so frustrated I was losing my objectivity.

why not replace:
$TickerData = array ($Symbol => $Price);
that line reassigns $TickerData to a array with one element in it everytime
you call it. The last time through your loop, $Symbol = ''
and $Price = '', so you get Array ( [] => ) when you print_r
with this:
$TickerData[$Symbol] = $Price;

Are you sure that the line: echo $Symbol ...
is displaying something sensible for each $Row?
You're overwriting $TickerData at each iteration of the foreach-loop thus if
your last $Row doesn't contain something sensible neither would $TickerData.
You probably want to use this assignment instead:
$TickerData[$Symbol] = $Price;

Re: [PHP] Str_Replace Command
Well this is it and it is really got me...
Echoing out the $Symbol and $Price works just fine one row about the
$TickerData array assignment. Yet it outputs nothing.
"Array ( [] => )" is what I get. If I change the line to
$TickerData = array ("$Symbol" => "$Price"); I get nothing, or the same
result. If I change the line to
$TickerData = array ('$Symbo'l => '$Price'); I get the following
Array ( [$Symbol] => $Price ) which tells me the assignment works, but it
seems like the $Symbol and $Price variable are blank when assigning to the
array. I know that they are not blank since they echoed out just fine one
line above.

Re: [PHP] Str_Replace Command
Ok I got around it by the following, but now I have a new problem. I can not
get the two dimensional array working. I want to later be able to output a
variable like this $TickerData["IKN"] and it will output the associated
$Price.
$StockURL =
"http://finance.yahoo.com/d/quotes.txt?s=xrx,ikn,danky&f=sl1&e=.txt";;
$StockResults = implode('', file("$StockURL"));
$Rows = split("\n", $StockResults);
foreach($Rows as $Row) {
list($Symbol, $Price) = split(",", $Row);
$Symbol = str_replace('"', "", $Symbol);
$TickerData = array("$Symbol"=>"$Ticker");
}
print_r($TickerData);
echo $TickerData["IKN"]."\n";

str_replace() RETURNS the replaced string. It does not alter $Row.

[PHP] Str_Replace Command
I have never had this problem before and it is probably something simple...
Please take a look at the two foreach statements. I am at a loss as to why
the second line does not actually remove the quotes. The first foreach
statement does so how are they different.
$StockURL =
"http://finance.yahoo.com/d/quotes.txt?s=xrx,ikn,danky&f=sl1&e=.txt";;
$StockResults = implode('', file("$StockURL"));
$Rows = split("\n", $StockResults);
foreach($Rows as $Row) { echo str_replace('"',"",$Row)."\n"; }
foreach($Rows as $Row) { str_replace('"',"",$Row); echo $Row."\n"; }
Eventually, I need to break apart the $Row into two elements $Symbol and
$Price and then into a two dimensional array. I have done this with the code
below, but so far, I can not get rid of the quotes.
foreach($Rows as $Row){
list($Symbol, $Price) = split("\n", $Row);
$TickerData=array("$Symbol"=>"$Price");
}
