Nifty, but you'll notice that I'm using MySQL, not SQLite3. And you
didn't mention which version PHP you're using.

it had occurred to me that you may be using a diff db and that could have
something to do w/ it; however, ive just made a slight alteration to the
script and its working np w/ mysql:
-----------
sql
-----------
mysql> create database TESTING;
Query OK, 1 row affected (0.00 sec)
mysql> use TESTING;
Database changed
mysql> CREATE TABLE TESTING (
-> id INT NOT NULL AUTO_INCREMENT,
-> name CHAR(30) NOT NULL,
-> PRIMARY KEY (id)
-> );
-----------
php
-----------
<?php
/**
* lets test a PDOStatement::rowCount() bug
* using an sqlite3 database
*/
try
{
$oPdo = new PDO('mysql:host=192.168.56.101;dbname=TESTING', 'root', '');
$oStmt = $oPdo->query("INSERT INTO TESTING (name) VALUES ('nate
dogg')");
echo 'Num rows inserted: ' . $oStmt->rowCount() . PHP_EOL;
$oStmt = $oPdo->query("UPDATE TESTING SET name = 'snoop dog' WHERE id =
1");
echo "Num rows updated: " . $oStmt->rowCount() . PHP_EOL;
$oStmt = $oPdo->query("DELETE FROM TESTING WHERE id = 1");
echo "Num rows deleted: " . $oStmt->rowCount() . PHP_EOL;
}
catch(Exception $oE)
{
die($oE->getMessage() . PHP_EOL);
}
?>

Update: MySQL 5.1.44.
rowCount() appears to return 0 only on deletes, not updates or inserts.

I have a desktop app that has a data structure that looks like this:
typedef struct MANGOpie
{
unsigned char mango;
unsigned short pie;
}
MANGOpie;
I manage a C array of these things in memory:
MANGOpie * pies = (MANGOpie *)malloc(count*sizeof(MANGOpie));
I pass these to a PHP script on my webserver who needs to unpack the
array of structs.
The unpack() PHP function appears to be what I need, but it doesn't
like the formatting I'm using to describe an array of these structs:
"(Cmango/npie)*"
What it doesn't like are the parentheses. I've tried brackets and
curlies too, but nothing works. I have to have the parentheses to tell
the parser to repeat the entire struct:
mango
pie
mango
pie
mango
pie
...
Formatting without the parentheses -- "Cmango/npie*" -- is:
mango
pie
pie
pie
pie
pie
...
One workaround is to drop the struct and just manage two separate
parallel arrays of each data type in the desktop app:
unsigned char * mangos = (unsigned char
*)malloc(count*sizeof(unsigned char));
unsigned short * pies = (unsigned short
*)malloc(count*sizeof(unsigned short));
With PHP unpack() format strings:
"Cmango*"
"npie*"
But, I'd rather keep the struct for the sake of code clarity and neatness.
Another would be to iterate thru the binary data, unpacking one struct
at a time, but that would be slower, presumably.
Anyone know the trick to this?
Thanks.

I'm curious how you are getting to the point of calling pack() in the
first place. can we see the bit of your script that interacts with
this c code?

I'm actually moving from a string-encoded transport to binary for
compactness. The array can potentially get pretty large. I'm shooting
for the smallest possible representation of the data, which is 1 char
and 1 short per data point.

In the desktop app's memory the data is packed end-to-end already:
typedef struct MANGOpie
{
unsigned char mango;
unsigned short pie;
}
MANGOpie;
MANGOpie * pies = (MANGOpie *)malloc(count*sizeof(MANGOpie));
...and the entire 'pies' array is sent to the PHP script as binary data
using PUT.

Even if the mailserver does pipelining, he'll still need to do the EHLO
separately and wait for the response to see if it does. After that you
can fire off everything in one go.

Hi,
Well people better than me (how is that possible?!) have said that
$_REQUEST has the potential to open your app up to security
vulnerabilities, and that it should be avoided because of that. Here's
a post from Stephan Esser about it on the PHP-Internals list:
http://www.mail-archive.com/intern...@lists.php.net/msg32832.html
Stephan heads up the Hardened-PHP project and when it comes to
security, I don't know of anyone better. So, if he advises not to use
_REQUEST, it's a good idea to follow that advice.

Well, he's only saying there that it 'most probably vulnerable' and
mentions that cookies can overwrite post and get data. This isn't a
problem with $_REQUEST itself but rather an applications' use of it. So
what if someone crafts a cookie to send a bad value. If someone has the
gen to do that, then they are going to know how to send get and post
values as well. Only decent sanitisation will be able to protect against
this.
If the order of override variables in $_REQUEST is such an issue too,
use the request_order ini setting to specify the order you'd prefer.
I've never had any issues with using $_REQUEST, but found a lot of
advantages to using it, as I often use a mix of data sources in the same
app.
Thanks,
Ash

Slash is the wrong character. The correct SQL escape character is the
single quote.
The best way to prepare text fields is to use the DB specific escape
functions on each text field before assembling the command string, i.e.
pg_escape_string(). But that is after all fields have been sanitized and
validated.
In addition, if magic_quotes is turned on, you also need to remove them
before doing the validation. The contributed notes in the online manual
have some good suggestions on how to accomplish this.

Richard,
The use of $_REQUEST it no more a security hole than $_GET or $_REQUEST,
they should ALL be treats as bad data until normalized and sanitized. The
claim that it opens a security hole is just false, that's like saying PHP
is insecure, its not it just allows for lazy coding such as $_REQUEST.
It represents a way for people to exploit coders who don't know any better.
Expecting a cookie value to come through in $_REQUEST but you could
override using a query string parameter makes for easy exploitation.
And how is this more secure? I can create a cookie, send post or get
on my client machine and send anything I want to the server. Just
because you are getting a cookie does not mean that you created it :)
So you might as well use request because the data can not be trusted
either way.

John
It is true that you cannot trust any data coming from a client (i.e.,
POST, GET, COOKIE, REQUEST, Whatever).
However, in trying to secure what you are doing it makes sense to
know specifically the origin of your data.
Additionally, if you know specifically where your data is coming
from, then there are no surprises as there can be by using REQUEST.
I am sure you realize that the data provided by a REQUEST can be
overridden by processes you may have not accounted for. For example,
while you are thinking that the data you're working on was provided
by one super global it actually was overridden by another can lead to
problems, including security.
One security directive is to keep the process simple and under
control. The more complicated you make it, the less secure it becomes
regardless of the method of data collection.

tedd

Hello guys, I try to use 'ReflectionFunction' to retrieve the info of a
function.
For example:
<?php
$rf = new ReflectionFunction('strstr');
echo $rf;
?>
=============== output ==================
Function [ <internal:standard> function strstr ] {
- Parameters [3] {
Parameter #0 [ <required> $haystack ]
Parameter #1 [ <required> $needle ]
Parameter #2 [ <optional> $part ]
}
}
The problem is there's no 'return type' (i.e. 'string' in this example)
info about the function.
Could you tell me how to retrieve the 'return type'?
Thanks.

I think PHP doesnt support it.
In ReflectionParameter class you'll see there is no parameter type too.
May be this is because PHP is loosely typed language.

That's not possible. Consider this function:
function foo()
{
switch (rand(0, 1)) {
case 0: return 42;
case 1: return 'bar';
}
}
What should the return type be?

It can be anything you want to test for -- check out:
is_int();
is_nan();
is_float();
is_long();
is_string();
IOW, is_whatever();

I've always found 'dog' and 'rabbit' to be more stimulating.

A real programmer would use the one hand!
Real programmers use 'cat'.

It works like it is ... once. What I don't understand is why the client
browser(s I have tried it with Firefox and IE 6) can't find the Javascript
function the second time.

I've had a look, but I'm not sure what you're trying to achieve with
your Javascript. The .js files seem to be present in the page even after
entering dummy access details into the page. You said you're using PHP
to modify what gets put into the .js file. Are you maybe modifying it in
a way that breaks the javascript?
Thanks,
Ash

that would be my guess too... firefox + firebug will often give
accurate error messages for badly formed js.
the error itself is known to be caused by malformed js unable to be
parsed by the browser.
ie(8) does more js syntax nagging than most other browsers.

That only puts one arm out of action surely? A real programmer would use
the one hand!
Only joking, hope his/her surgery goes without any problems.
Thanks,

I was thinking the same thing. I suffered a massive DVT and PE that
confined me to a hospital bed for three weeks, yet I worked almost
every day with my laptop. Some clients understand and some don't.
