"Array to String Conversion" error when constructing a multi-dimensional array

[drako]

Hi,

I'm a bit stumped as I am getting a "Notice: Array to String
Conversion" error when trying to do something that on the surface
should be a very simple task - create an array, and write a set of
values to them based on data submitted from POST Fields.

Code below:

$_SESSION["increment"] = array();
$x = 0 // Counter - This will be
incremented

$_SESSION["increment"][$x] = array("increment_bond" =>
$_POST["increment_bond"],
"increment_amount" = $_POST["increment_amount"],
"increment_comm_date1" = $_POST["increment_comm_date1"],
"increment_comm_date2" =$_POST["increment_comm_date2"],
"increment_comm_date3" = $_POST["increment_comm_date3"]);
It keeps throwing out that error, and does not write any of the POST
Values to the array (the POST values are definitely getting sent, so
that is not the problem).

If I dump out the value of $_SESSION["increment"], I get "1A" ?!?

I'm sure that there is a pretty simple mistake lurking somewhere - I
just can't seem to figure it out.

Any suggestions or hints ?

Thanks
Neil.

Hi Neil,

Your code looks perfectly OK to me.
Are you 100% sure this is where the error is thrown?
Did you try:
<pre>
<?php print_r($_POST); ?>
</pre>

Does it produce all used postvars you expect?

Regards,

[drako]

Erwin,

I have tried <?php print_r($_POST); ?>, and it outputs all the POST
vars that were submitted. So now problem here.

And the error is thrown at the line that begins
"$_SESSION["increment"][$x] ........"

I have tried this code on two different systems (5.1.6 on OSX, and
5.2.0 on NetBSD), and the same error keeps occuring.

Very puzzling.

Neil.

OK,

I inserted the debugging statements as you suggested:
$_SESSION["increment"] = array();
echo '1: ';print_r($_SESSION["increment"]);echo '<br>';

$x = 0 // Counter - This will be
incremented
echo '2: ';print_r($increment); echo '<br>';
$_SESSION["increment"][$x] = array("increment_bond" =>
$_POST["increment_bond"],
"increment_amount" = $_POST["increment_amount"],
"increment_comm_date1" =>
$_POST["increment_comm_date1"],
"increment_comm_date2" =>
$_POST["increment_comm_date2"],
"increment_comm_date3" =>
$_POST["increment_comm_date3"]);

echo '3: ';print_r($_SESSION["increment"]);exit;

<------->
The output is:

1: 1
2:
3: 1A
I'm still no wiser as to what is going on here....

It doesn't actually relate to anything; but I suspect it was suggested
just to see if anything was output - and nothing was output.

I know if 'register_globals' is switched on, this could potentially
cause a problem, but in this case, globals is switched off, so is not
the problem.

I now suspect this is session-related in someway. As the code looks OK,
the problem arises from elsewhere....

Nope.
Keep in mind, that on strings, the [] will get or set the character of the
string at that particular location. My suspicion is that you don't give us
the real code (for where would the incrementation take place?), and you
turn the array into the string ( or number) '1' somewhere. (This often
happens when you use the return of a function (true) that works be a
reference instead of a return by accident.)

So, in the first loop, we've made $_SESSION["increment"] into a string by
accident. On the second loop, if $x = 1, that's the second position in the
string (which was not previously set). You try to set a character to an
array, so the array is converted to a string ('Array'), then it takes the
first character ('A') from that string, and put it at position 1. Hence
resulting in '1A'.

If you gave us the real code, I'd bet we'd spot where the actual overriding
on $_SESSION["increment"] takes place.

That sounds like a very probable scenario you described and deducted from

There doesn't seem to be anything wrong with the code you posted (except
for a missing semicolon after $x = 0), so I suspect the problem lies
somewhere in your other code.

Because of this missing semicolon, I suspect you have chopped out a
section of code between '$x=0' and '$_SESSION["increment"][$x]=array(...)'.
That is almost certainly where your problem lies. In particular, I think
you may have assigned some non-integer value to $x at some point.

Do 'print_r($x);' just before the error happens and see what you see.

You are correct in assuming that I chopped out a line when I posted
this...

The missing line between '$x=0' and
'$_SESSION["increment"][$x]=array(...)'.

is

if(isset($_SESSION["increments"])) {$x =
count($_SESSION["increments"]);}

The purpose is to count the number of entries in the array - if count
returns '5', then the last value of $x would have been 4, so we can
assign '5' as the next value in the array.

Could this be the offending line...

Sorry, the extra line of code above should have read:

if(isset($_SESSION["increment"])) {$x =
count($_SESSION["increment"]);}

I just noticed the typo, in case anyone has been sharp enough to spot
it...

But that's not it afaik. See the comment about just using empty [], this
will just add an array-value to the end.

However, there's something else going on in the adding. Posting the total
code that works on $_SESSION["increment"] woudl speed up the process :-).

You probably have a $_SESSION["increment"] = something(); somehere, where
the function just returns true instead of a processed array, casting it to
the '1' string.

Well, that remains to be seen, but thank you, would be nice if I would get

It helps that I cannot get the difference of array_walk() and array_map in

Is your $_SESSION['increment'] accessed/altered anywhere else in the
script? Check for it.
Also, add this before "if($_POST['increment'] == 1)":

if(isset($_SESSION['increment'])) var_dump($_SESSION['incremenet']);

Most likely, you overwrite the $_SESSION['increment'] somewhere else in
your code, so it get's cast to a string. Check your code for every
'$_SESSION['increment']= ', and carefully consider the return of the
function after it...

Concerning your earlier post, great deductive reasoning, Rik. *bows*

Just to reiterate to the OP, you need to check if you're assigning
$_SESSION['increment'] a function's return value, or possibly even
directly a string, at some other point (potentially in a different
file, since it is a session variable).

Also, you could a foreach loop, so as not to manually maintain the
array's index.

Curtis

[drako]

I got this working in the end. It seemed that having the following
variables caused some clash:

$_POST['increment']
$_SESSION['increment']

once I changed this to $_SESSION['increments'] (notice the plural),
then it was creating arrays within the session variable as expected,
and I can now run it through a 'foreach' loop and 'array_multisort' in
order to process the array data.

Thanks for all your help and suggestions on this one.

[despirately trying to claim the fame]

Well, you're copying the POST to the SESSION somewhere in your code in that
case, as it is not a PHP feature. This works fine:
<?php
session_start();
if(!isset($_POST['submit'])){
$_SESSION['increment'] = 'This is the session value';
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="increment">
<input type="submit" name="submit">
</form>
<pre>
<?php
echo "The SESSION is {$_SESSION['increment']}\n";
echo "The POST is {$_POST['increment']}\n";
?>
</pre>

And upon posting "This is the post value" in correctly displays:
The SESSION is This is the session value
The POST is This is the post value

I'd say my claim you've turned it into a string stands :-)

Well, you're copying the POST to the SESSION somewhere in your code in that
case, as it is not a PHP feature. This works fine:
<?php
session_start();
if(!isset($_POST['submit'])){
$_SESSION['increment'] = 'This is the session value';
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="increment">
<input type="submit" name="submit">
</form>
<pre>
<?php
echo "The SESSION is {$_SESSION['increment']}\n";
echo "The POST is {$_POST['increment']}\n";
?>
</pre>

And upon posting "This is the post value" in correctly displays:
The SESSION is This is the session value
The POST is This is the post value

I'd say my claim you've turned it into a string stands :-)

Or, maybe register_globals is enabled?

That would not overwrite the $_POST & $_SESSION arrays, and even then, the
$_SESSION would win the $increment, and the $_POST value would be
discarded.

As posted, that is true. But we don't know what other code he has
which isn't posted. Perhaps he has something like $increment=4; in
another place in his program.

Also, which variable wins the $increment depends on the php.ini
settings. The default is GPCS (Get/Post/Cookie/Session), but that can
be changed.

Indeed, but it seems quite rare that change would be made to the
default order. Also, the OP stated above, he has register_globals off.

Ah, this is a setting? I memorized GPCS, it never occured to me this was
configurable. Learn something new every day :-)

Curtis,

Yes, it's unusual, but not unheard of.

As for register_globals being off. I've had people claim that is the
case - but then later found out it wasn't. They were looking at the
wrong php.ini file and/or had it overridden. I never trust any settings
without seeing what phpinfo() has to say.

That's a good point, Jerry. Ruling things out too early can impede
problem-solving. When I was developing one project, I didn't realize my
host had register_globals on, ugh, quite a pain, if only I had been
wise enough to check phpinfo() before hand. Now I know better, at
least.
