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)."<br>\n"; } foreach($Rows as $Row) { str_replace('"',"",$Row); echo $Row."<br>\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"); }
