Description:
------------
---
From manual page: http://www.php.net/function.fopen%23Parameters
---
The function used to return a csv file with a stock quote with PHP 5.2.9.  However, now with 5.2.17 the function will replace '&' with '&' and it returns a csv file with just the text: "Missing Format Variable".

It is easy to verify by using a malformed URL with '&' in it and on the resulting html, view source and the error message will show '&' where '&' should be.  I have been unable to locate a workaround.  

Test script:
---------------
fopen("http://finance.yahoo.com/d/quotes.csv?s=ABT&f=sl1d1t1c1ohgvpnbaejkr&o=t", "r");

I tested this on the 5.4 alpha and did not have this problem.

Here is my test script:
----------------------
<?php
error_reporting(E_ALL);
$fh = fopen("http://finance.yahoo.com/d/quotes.csv?
s=ABT&f=sl1d1t1c1ohgvpnbaejkr&o=t", "r");
while( !feof( $fh ) ){
        echo fgets( $fh ) . "\n";
}

Result:
---------------------

I have tried your script on 2 Windows machines with Apache 2.2.11 and PHP 5.2.17 and my results match yours.  I was sure I saw it when I first upgraded to 5.2.17 on my machine, but this now seems to be an issue with the web host rather than a bug in php.  Sorry for the red herring.  I am changing the status to closed.

Closed is for fixed issues. Changing to Bogus.
