I am having a bit of a confusion printing the values of an array i have. When i
print_r this array it contains the following:
Array ( [ValueA] => ValueA [ValueB] => valueB [TestValue] => TestValue [Errors]
=> Array ( [0] => Array ( [ErrorId] => AD27JH [ErrorMsg] => OK ) ) )
I can get the values of ValueA, ValueB and TestValue but I am a bit confused
at getting the values of ErrorId and ErrorMsg.
e.g. echo $arrayName['ValueA']; // will display the value contained there
am thinking echo $arrayName['Errors']['ErrorId']; // should display the value
but it does not
Anyone wants to shed more light ?
Cheers

suggestion for next time. echo a <pre> or <plaintext> tag out before you echo your array next time
and you will then see the nesting of the arrays
Doing that would have made the answer to this question very obvious

Sure, but if you don't make your intentions clear from the start then
there's no use complaining afterwards. Not quite an accurate analogy but
here goes:
"If you leave valuables around your house and leave the doors and windows
unlocked you're not going to get much sympathy from the police (or the
insurance company for that matter) when you get burgled."
So, if you don't use a suitable license then you don't have a stick to
beat someone with should it ever come to it.

In addition to using escapeshellarg(), I would first determine if the input
file or directory exists before executing the command. This adds another
layer of protection.
<?php
// Example code
if(file_exists($_POST['file_or_dir_name'])) {
$command = "ls ".escapeshellarg($_POST['file_or_dir_name']);
exec($command);
} else {
echo "File/Directory does not exist!!";
}
?>

:-)
I get that too and it's the best description I could give in one
sentence. Basically, the session array $_SESSION is emptied. Without
notice, warning or error. Just emptied.
I tried to track it down with xdebug as well but it's really just
loosing it.
I will try to work on this problem this week, and basically looking at
the last hundreds of posts about sessions in this list, I would narrow
it down to the following possible problems and solutions:
1) Unsynched:
It is possible that client and server do not share the same notion of
time, which is stored in the session cookies, so the session would be
expired sooner than expected. A way to test if this is the problem is to
set the cookie lifetime to one year or more, and see if it improves
anything. However, if this was the problem, timeouts would tend to
happen after a definite period of time, not after a random period like I
have and like Sascha seems to have as well
2) Mutex 1:
The problem might be due to concurrent (or almost) uses of the session,
either with AJAX code or with frames, which might mean that the sessions
are not complete when accessed, or access is prevented by a blocking
write operation on the session file. This should only happen in the
context of concurrent requests, and the only possible improvement might
be to use session_write_close() as soon as a session use is finished, or
to use mutex-aware session handler functions.
I wonder if, in this case, the session should really be lost and
emptied... maybe a write still allows a read to work...
3) Mutex 2:
When using alternative session handlers, these session handlers might
not be mutex-aware, so a concurrent access prevents data from being
written before it is read. Make sure your session handling code is
mutex-aware (apparently there is some code documented in the user
comments of the PHP online doc).
I hope this helps. I'll try to come back and report if any of these
solutions has worked for me.
