[PHP] Returning reference problem
Starting over since my last thread had too little effort put in it. I
have this script that should create a multi-demensional array that would
resemble a directory structure. The problem is that after adding one
element to a folder it appears to be creating a new object instead of
adding another item to the current object. So there can only be one
file or folder in the parent folder with the exception of the top
level. My entire script is below.
Thanks, Jon

I need a validation regex that will pass a string. The string can

characters except two consecutive ampersands () anywhere in the
string.
I'm stumped - ideas?
Yup, use this perl regex:
/^(?:()(?!)|[^]){1,5}$/
Where 5 above is the maximum length of the string. You can change this to
any positive value and the regex will still work. Basically it says look
for 1 to 5 single characters where each either isn't an ampersand, or IS an
ampersand but isn't immediately followed by an ampersand. The (?!) is a
zero-width negative look-ahead assertion which is like other assertions such
as \b that don't eat up the portions of the string that they match.
Sample code, tested:
$maxLen = 5;
$testStrings = array(
'a',
'g',
'df',
'adfdf',
'adfsdfff',
'ff',
'dfds',
'dsdf',
'ddf',
'dff'
);
foreach ($testStrings as $string) {
if (preg_match(/^(?:()(?!)|[^]){1,$maxLen}$/, $string)) {
print $string matches.\n;
} else {
print $string does not match.\n;
}
}
Hope this helps you (pass your exam? ;) )

[PHP] Sessions memory allocation problem
Hi,
I am testing the following code that pushes a file to the browser
(Apache 1.3 + PHP 4.3.8 but tested also under several other configs)
Try it with a BIG test1.zip (e.g. 100M in size)
?php
ignore_user_abort();
set_time_limit(0);
session_save_path('/tmp');
session_start();
$sFileName = 'test1.zip';
$sFileDir = '/var/www/html/';
header(Content-Type: application/octet-stream);
header(Content-Disposition: attachment;filename=\ . $sFileName . \);
header(Content-Length: . filesize($sFileDir . $sFileName));
header('Pragma: cache');
header('Cache-Control: public, must-revalidate, max-age=0');
header('Connection: close');
header('Expires: ' . date('r', time()+60*60));
header('Last-Modified: ' . date('r', time()));
$oFp = fopen($sFileDir . $sFileName, rb);
$iReadBufferSize = 512;
while (!feof($oFp)) {
echo fread ($oFp, $iReadBufferSize);
}
fclose ($oFp);
exit;
?
What i discovered is that if i keep the 2 session initialisation functions
the script will work ONLY if the allocated memory is greater than the size
of the tested file. If i remove the session functions the script works fine
even if the test1.zip file is very big (hundreds of Megs)
Is it something i do wrong? Or is a bug and i should report it?
I mention that I NEED the 2 functions so removing them is not THE solution.
Nor setting in php.ini a huge memory limit :(
Thank you,
Adrian Zaharia

Thanks...I actually just realized that the parentheses around the first
ampersand are unnecessary (that was a leftover from a previous attempt), so
this is simpler and will work just as well:
/^(?:(?!)|[^]){1,5}$/
Or if you don't care about capturing portions of the match and then throwing
them away:
/^((?!)|[^]){1,5}$/

[PHP] Permissions on uploaded image don't allow for over writing
PHP List, The Situation: I am building a content management system where users can, among other things, upload images into a directory. The Problem: The image uploads fine, but once it's there, it can't be over written. So if a user uploads an image, and then changes his or her mind and wants to upload a new version over it, the file upload fails. What I've Tried So far: I can manually edit the file permissions using chmod and setting the files to 777. But of course that's not something I want to have to do every time someone uploads a file. I don't know enough about file permissions and settings to know how I can set these permissions at the time that someone makes the upload. The Question: How do I allow a user, who is uploading via the web, place an image on the server with permissions that allow the file to be over written? -- Dave Gutteridge [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This could result in LOTS of entries in crontab, but less load on the server. 2. There is one job put in the crontab file that is executed every five minutes. This job will be executing a PHP file that runs through the database for the current user and checks to see if any events need to go off at that time. This will result in only one event in crontab with a greater potential for load on the server. I'm leaning towards Option 2*. What do you think? What other options do I have? I'd go with option 2 also. Option one wouldn't really be less load, as it would be more for cron to parse, and pretty much execute the same amount of times. Option 2 needs cron too, and the parsing is done by php instead of cron, so this is not really valid point. Option 1 also brings into question security and access. To add entries to the users crontab, your script would have to have permission to do so (suexec?), and giving it that much access could be dangerous. This is a valid point if php scripts are executed as apache user. What about option 3: Use at command to execute php script when the next event should be executed.

I tried pear install fileinfo, and got the message No release with state equal to: 'stable' found for 'fileinfo'. I installed Pear for the sole purpose attempting to get fileinfo compiled. I know *nothing* about it. If I'm understanding you correctly there may be a way to modify the pear config to compile unstable releases?

[PHP] best way to handle user authentication, PHP vs. apache
Hello; I'm trying to figure out the best (most secure and most user friendly, security of primary importance) way to let a user log-in. I am setting up a web application (database application) that will be for private use only and I want to keep it secure. As I understand it, using the Apache htaccess method is secure as there is essentially no communication without a username and password, but it does lack a little in flexibility and presentation. On the other hand, PHP certainly has the edge on flexibility and presentation, but I have questions regarding it's security. If you look at the threads regarding connecting to databases, you often see a warning to the effect of: store your connection password etc, outside of the document path in case PHP fails and your file is displayed unprocessed. So my question is, how can you count on PHP to log somebody in, and prevent access to files when PHP may fail, or the user could just go into the directory structure and bypass security.

[PHP] Regular expressions stopped working
Hi! I had a script for parsing text into html, similar to phpBB. Everything has been working fine until now. Some of my 'pseudotags' like [b] are still recognized (parsed into b) but some more advanced pattern matching is not. I haven't changed the code, but the php-version on the server has changed from default on debian-woody to php-4.3.10. I haven't made the upgrade myself. The users of the site reported the bug to me this week, but the users aren't active so I don't really know when then bug was created. Because I know it has worked before. Does any of you have a clue or experience of this? Or has my code been mysterious altered on the server? Thanks!

[PHP] Image Creation and Saving
Hello everyone,
I have been troubleshooting a problem with one of my scripts for a
while now, its purpose is to allow a user to upload a file, save it to
the server, resize it into a thumbnail, and save the thumbnail as
well. In my script all goes well until it comes to saving the images,
the script throws these errors:
Warning: imagepng(): Unable to open
'/home/blacknut/public_html/picserv/picserv_mysql/pictures/blacknute/15.png'

it as well.

strtolower($_SESSION['user_sn']) . '/' . $new_pic_filename . 't.png');
//Save image thumb
I am very new to file/image manipulation in php so if you see any
errors, or unnecessary code please tell me. I'm not quit sure how
everything works, although I do have a theoretical picture of how it
does. Any comments will be appreciated.

[PHP] design pattern/code generators
Hi All,
I am looking for advice regarding design patterns/code generation in PHP5.
I have a simple code generation tool (written in PHP) to interface with
database. It works fine for simple situations but seems a little
strange for more complex ones.
Suppose I have a table user (id, name, age) and a table
account(idAccount, idUser, name). My generator creates a class for each
table and a standard db class. Each class basically has a set/get
method for each property and some standard insert, delete, update,
search methods
ex.
class user
{
var $db
function setName(..)
function getName()
function insert()
{
$this-db-query(insert into user values...)
}
...
}
I've omited the other methods/constructor but you can get the picture.
The problem comes when I have to access information the comes from 2+
tables. Suppose I have to show all users accounts. Now I end up with
something like this.
$u = new User() ;
$a = new Account() ;
if($u-search())
{
for($i=0;$i...)
{
$idUser = $u-getId() ; $u-next() ;
$a-setIdUser($idUser) ;
if($a-search())
{
// print
}
}
While this works I feel there must be an easier/cleaner way. If I was just
querying the database a join would give me the result in one pass.
In my case what should I do ? create a new method showAccounts ?
Where should I put it, in User or Account class ?
I am interested in advices regarding how to design it better so I can
make the proper adjustments in my generator.

[PHP] Is this a mysql_connect() bug?
Hi,
I tried mysql_connect() function, and it won't reture FALSE if
connection failed. Instead, the script times out after 30 seconds and
displays an Fatal error message Maximum execution time of 30 seconds
exceeded. For example:
mysql_connect(' ',' '); returns TRUE because mysql logs in the user as
guest. But mysql_connect('servername','username','wrongpassword');
does not return FALSE. Instead, the script continues until it times
out. Does anyone know if this is a known bug, or can this be fixed by
changing a diretive/setting that I don't know about?
thanks,
Tom
P.S., I am using PHP 4.3.10, Apache 2.0.52(win 32), MSIE 6.0, Mysql
4.0.23-nt, Windows NT 5.1 (XP)

I think the issue here is if the server does not respond it hits the
execution time limit before the function returns.
I use code like this:
$olderr = error_reporting(0);
set_error_handler('ignoreerrhandler');
$dbHandle = mysql_connect($dbHost, $dbUser, $pw);
restore_error_handler();
error_reporting($olderr);
.
function ignoreerrhandler($errno, $errstr, $errfile, $errline) {
return;
}
You can also control the connection timeout with the
mysql.connect_timeout setting in php.ini.

Re: [PHP] Is this a mysql_connect() bug?
Thanks for the error handling code. I think PHP still has a basic
problem. If mysql sever connection times out because wrong username or
password was used, then mysql_connect() should return FALSE. But this
is not the case, why? Is it possible that mysql_connect() could not
read the connection failed message from mysql server?

Is it possible that mysql_connect() could not read the connection failed message from mysql server? I don't think this is case, because I thought that the problem could be that the script is timing out before MySQL can return a status code (possibly because MySQL is busy; network congestion, etc.) However, after reading this: Note: The set_time_limit() function and the configuration directive max_execution_time only affect the execution time of the script itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running. I think the problem is not the script timing out, but rather it could be this: Note: Whenever you specify localhost or localhost:port as server, the MySQL client library will override this and try to connect to a local socket (named pipe on Windows). If you want to use TCP/IP, use 127.0.0.1 instead of localhost. If the MySQL client library tries to connect to the wrong local socket, you should set the correct path as mysql.default_host in your PHP configuration and leave the server field blank. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
