Description:
------------
Hello,

I'm actually using PHP 5.1b3, however it was not an option in the version select box. I just upgrade from PHP 5.1b2 so I know that the issue is definitely with the latest beta release.

I am somehow (randomly) getting strange array keys after parsing cURL data with parse_str().

When this occurs, it's usually the first array key that is garbled. In most cases the key contains either partial serialized data or portions of the path to the script.

Reproduce code:
---------------
<?php

// brief snippits of code:
$result = curl_exec($ch);

$retval = array();
parse_str($result, $retval);

print_r($retval);

?>

Expected result:
----------------
Array
(
    [testdomain_com] => pointer
    [testdomain2_com] => pointer
)

Actual result:
--------------
Array
(
    [a:1:{s:5:\"sttestdomain_com] => pointer
    [testdomain2_com] => pointer
)

I forgot to mention the output formatting issue. Again, this is very strange! 

When the array problem indicated above happens, the HTML output of the PHP script gets garbled as well. Certain data that was once included in table cells get bumped out of the table, text is garbled together, etc.

For example, in one of my table cells, a phrase is quoted ("domain.com"). When this error occurs, part of an <A href> tag that is located at the bottom of the page gets spliced into the quote. I'm not using CSS or anything like that either. Also, in this same example, I've seen additional </TABLE> tags (magically?) appear where they don't belong, causing stuff to output funny. Hope this helps!

Thanks!

Please provide more information about your system (web-server name, it's version, SAPI you use, etc.).
Are you able to reproduce it with PHP CLI ?

Hi,

Here's some information that may help:

I've also noticed some crashes:

How do you find out the SAPI information you need? Also, I'm really not sure if it can be reproduced via the API. This is a very large application and it would take allot of maneuvering to get it to run from command line, but I suppose I can if you really need that info.

Oops! I mean't CLI, not API

Thanks!

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
