Hi Folks,

it is always better to know what you want to allow and only allow those.
this will catch anything that is not a letter of the alphabet.
if ( preg_match('!^[^a-zA-Z]+$!', $userid) == 1 ) {
die('Found something other then a letter.');
}
if ( preg_match('!^[^a-zA-Z0-9]+$!', $userid) == 1 ) {
die('Found something other then a number or letter.');
}
this returns an (int) either 0 or 1
0 = it did not match anything
1 = it matched at least on char that is invalid.
check out the function here http://us2.php.net/preg_match
check out its big brother http://us2.php.net/preg_match_all
The big difference is that preg_match will only look until it finds the
first match, then it stops looking and returns.
preg_match_all finds all possible matches in the input string.

but I think that would still leave me open to control characters. I am
thinking maybe I should loop through the string character by character
and check it's ascii value (using ord) is within the range of a-z and A-Z ?
Is this the best way of achieving this ? Is there a php command to do
something similar ? I have done a few web searches and haven't come up

[PHP] Question before upgrading to 5
Hi everyone, I just got done going through all my configure options for php5, and finally configure finished successfully... I didn't install it yet, have a question. Can I have both 4 and 5 installed temporarily until I'm sure all my scripts work ok? They should, I've been careful, but I want to be sure since this is the only server I currently have. I was going to install a virtual copy of fedora and do testing, but I don't have time, hopefully someone can answer. I think I just have to change the prefix to something other than default and load the new module in httpd. If I had more time I would do this the right way, but we all know how that goes... If this will work, I can then just uninstall 4.. Hopefully it won't break anything. I'll post my configure options if anyone would like to double check Thanks, Jake -- No virus found in this outgoing message. Checked by AVG Free Edition.

Just a note that while SSL may help to protect the session id from being packet sniffed you should still be concerned about storing sensitive data in _SESSION.

By default the session cookie expires when the browser is closed. You can change this by changing ini setting session.cookie_lifetime to something other than default value of zero, in number of seconds. I don't believe using HTTPS changes any of this, I have more than one app that use HTTPS for session cookies and have no problems with it persisting after the browser is closed (well, some browsers can do weird things sometimes... you never really know.) If the browser refuses the cookie, sessions won't work anyway. The session key is sent to the browser as a cookie (unless its in the URL...) www.php.net/session/ Take a look at cookie_lifetime and you might like the cache_expire docs on the same page too.

Hi Folks,
I am still pretty new to PHP and I have a question regarding
classes and
using _construct. Up until now I have been creating my classes as
follows:
class test1 {
var $name;
function test1($pName) {
$this->name = $pName;
}
}
So I when I create a new class I can assign 'name' by doing '$t1 =
new
test1("test1");'
As part of another thread I noticed the _construct function which
(if I
am correct) does more or less the same thing:
class test2 {
var $name;
function _construct($pName) {
$this->name = $pName;
}
}
I have fished around a bit and cannot find why one might be better
than
the other. The only thing I can think is that maybe you need to use
_construct to be able to use "extends" ?
Is this the case ? What is the advantage/disadvantage of using
_construct as opposed to using a function with the classname ?
Thanks,
JC

Learn it, know it, live it. What you need is a component of the ID which is not random, but is probably unique within the environment. Say, the IP address of the machine. Then, perhaps the process id of Apache/PHP process. Then, the random component, the time() (which is random with respect to the request, but unique for one second), followed by some rand() requests seeded by some high resolution micro timer. This will have a HUGH probability of uniqueness within the single process, so it is virtually assured, and a guarantee of uniqueness across all other processes and machines.

Bleh, you can solve this with at most 2 queries. CREATE TABLE foo ( id INT NOT NULL AUTO_INCREMENT, uid char( 50 ), PRIMARY KEY ( id ) ); There you go, a 50 character highly unguessable and guaranteed unique ID. Sure everyone knows the ID of the entry now, but that shouldn't be important. In fact it optimizes retrieval and validation by allowing the lookup to occur on an integer then validation by matching the full UID against the UID found for the ID. In all honesty though, hitting the database with random generated md5() hashes is probably more efficient since the likelihood of a collision is small and so in most cases you will only make one database query.

[PHP] Re: newbie question
Means you're passing the variable as reference.
This means that any change in the variable inside your function will affect
the variable outside your function, in other terms:
if you have
function myfunc(&$var){
$var = 5;
}
$a = 6;
myfunc($a);
will result in having $a=5 after the function all.

Actually, is not a bug, is expected behaviour and documented in the manual http://php.net/static See the last section, named "references with global and static variables" static and global are implemented internally as references, that makes storing references into static variables impossible (which can be solved by using arrays of references as seen in Robert Cummings example).

And seeing other Mysql discussion on this list inspired me to ask. 2) Why random? Incrementing not good enough for you? I want to use it in a way that will expose it to the user. And I don't want to give out information as to the order of records in my database.

RE: [PHP] Job Opportunity
While Jim does have a point and is limited by the threading algorithm of this list manager, someone can successfully argue that "this standard" has it's drawbacks. It is somewhat intuitive to pick up a message all pre addressed and reply to all, especially when your intention is to send a message that will "reach all". It is also somewhat intuitive to think that changing the subject means starting a new thread, however with thread id's hidden in the headers, this doesn't work. You CAN argue that standards that don't work are a bad thing, or at least, not a GOOD thing. I don't, however, have a good solution, since basing threads on subject lines has a different set of drawbacks like lots of broken or disjointed threads that have a beginning in another thread. These hidden ID's keep things together but they also generate lots of off topic discussion within a thread, like we are doing here ;-), pretty soon we should hear from those police.

Re: [PHP] Random Unique ID
function GenerateID ()
{
$len = 3;
$base='ABCDEFGHKLMNOPQRSTWXYZ';
$max=strlen($base)-1;
$activatecode='';
mt_srand((double)microtime()*100);
while (strlen($activatecode)<$len+1)$activatecode.=$base{mt_rand(0,$max)};
$len = 7;
$base='1234567890';
$max=strlen($base)-1;
mt_srand((double)microtime()*100);
while (strlen($activatecode)<$len+1) $activatecode.=$base{mt_rand(0,$max)};
return $activatecode;
}
this will generate and ID of 4 letters and 4 digits based on the current
time stamp..
ex: *QCKS9046 ...* the possibility of generating the same ID again is almost
0... (and you can make it even less if you increase the length)...
PS: I don't take credit for the code as it is a modified version of a code I
found long time back (this same code is running on one of my applications
for months without any problem)..

Re: [PHP] IP to City detection
It is very hard to get to the level of city. It is the way the networks are built. I live in a minor town. My provider has a node in this city, but it gathers all the traffic of the whole area (my town and neighboring towns) and sends it through an internal link to their major regional center. Depending on availability, my traffic might get to the Internet (uppercase Internet, the big, public, global one which links us all together) right through that regional node or, depending on traffic, it might get beamed over somewhere else and get into the Internet at another less busy node. Big providers are constantly shufling traffic around depending on the availabilty of their own internal network and that of their wholesale provider. The IP you see exposed to the Internet is that of the node where your provider internal network connects to the public network, the uppercase Internet. Due to national regulations, it is usually hard for one national provider to use IP addresses belonging to another country so, IP to country tables are quite reliable. IP to city is not reliable at all, there is not external rules imposing arbitrary borders on traffic so a provider is free to send packets wherever it becomes more efficient. Moreover, if a client has the same provider as your service, the IP address you receive might be an internal IP address and not an actual Interner address. Internal IP addresses have little restrictions, they can be almost anything. If that were the case, all bets are off. These days with the CeBit show running at Frankfurt, Deutsch Telekom (sorry about the spelling) might be struggling with their bandwith around that area. Data packets might be popping about everywhere in Germany and, if they have agreements with neighboring countries, some might be showing up at Denmark, Austria or Poland, who knows! My town is close to Barcelona, Spain. When they had the 3G mobile phone conference there last month, my packets might be going to Tarragona, Valencia or even all the way to Madrid. Comercial IP to location databases, at least, keep in close contact with the major providers so they have a close idea of how are they routing their packets. Non-comercial databases don't have the resoorces to keep updated. The only reason they are more or less reliable at the IP to country level is that governments have different regulations in each country and they know there is value in the information flowing through the optical fibers so, while they figure out how to tax those bits and bytes, they make it just a little more hard for them to flow from one country to the next, but within a single country, there are no limits.

I don't think you've established a baseline for comparison... It's a typo I wanted to write (more simple though) 'Is it secure ?' In several PHP security recommendation we can read "Do not let PHP open URLs through fopen, ". I think it's mostly related to crapy php applications that could be let users do what they want but is there any other problems with this practice ? Assuming you control the other server, you can make it as secure as you like... The server is fully under my control and I can order other servers if I can highlight that's a better approach to ensure the security of the data we serve. That server can also reject any requests that aren't from your web server IP (or list of IPs for a web-server farm). It's an approach but if my front-end is under the control of a cracker it will be unfortunately useless. You could set it up with SSL and use curl instead of url fopen -- You'd probably not want to waste $$$ on a CA, so you'd need the CURLOPT stuff to not check the peer stuff. I don't imagine using SSL without trusted CA. How secure is secure enough? Depends what your data and application are, more than any external factor. I cannot speak about the kind of data I have to protect on a public ML but data are confidential and I have to propose something to guaranty a vulnerability of the application doesn't expose all the data to the cracker. I'd also consider curl before FTP, personally, as it is more flexible if you decide later to use something other than the FTP protocol.

It's not that simple... Would you be happy with a web server that requires a human to review each HTTP request and sign off a form in triplicate before the HTTP response went out? :) that's an idea. I maybe should add in the requirement that the service should be usable :) Note: I don't mandate the service to be easy to use though. I fully accept constraints to access to the data if it's worth it. > The mains goal is to be still protected if their is an element under > attack on the application server, for instance a vulnerability in > apache (or even php according to the March month ;). What data are you protecting? See above.

Sure. Or you could just put them outside the webtree and not write stupid PHP code that lets them get executed. An attacker can use a vulnerability of either apache or php to gain apache user rights and make files executable and even run it (or run it with another vulnerability in another application required on the server). And you could check the upload files for validity, to insure that they meet certain criteria of non-executable files in the first place. Unfortunately, I cannot restrict the file type I accept. I would say that one of the goal of the application is to delivery binaries (executable). > - cracker uses a vulnerability and obtains the same rights than the > web server (due to mod_php) she will be able to access to all the > files (at least in read mode) because the user who runs apache have to > be able to read them. Is this on a shared server? No it's not. We are talking about a dedicated box in a DMZ with all the network security devices tailored. Is your PHP binary reading script dumb enough to allow them to access the files they shouldn't be accessing? I don't think so (code was audited) but I cannot guaranty there is no bugs in my application. > There are probably other things I don't imagine but I think the usage > of another server to host data is a good approach. I think it's a great approach, if the data being secured warrants it and the web application is well-written. I think it's a waste of time if the data being secured is not w

Re: [PHP] Sockets problem
Thanks for the answer. In the meantime I've managed to solve the problem be removing the pcntl_wait call. Actually I think this is a bug, because as I understand things pcntl_wait shouldn't block the main process, but I don't have experience with either sockets or Unix process, so I might be wrong.

You can see the bug > report at http://bugs.php.net/bug.php?id=40864 Looks like a pretty cogent bug report to me... Perhaps Tony would like to see the same script in non-fork single-connection mode on the same server, to prove that the ports/firewalls/etc are not at fault. Or, perhaps, there's something inherently wrong with that script... I'd also suggest taking out the 'fork' business and just opening up two sockets in two scripts, to remove the pcntl (possible) red herring -- boil it down to absolute minimum. -- Some people have a "gift" link here.

Robert Enyedi wrote: I'm not very familiar with the internal architecture of the Zend PHP engine nor with the PHP module mechanism, but can you reuse compiled PHP modules in other applications? Is there a way of calling the functions of a compiled module from a third party C application? Thanks, Robert Compiled PHP modules could be loaded by any C program (as with any C shared object) but there would be a large number of hoops you would have to jump through before you would be able to make any function calls. However, is the module you wish to use something that is available exclusively to PHP? Most modules are wrappers around existing C libraries and as such it would be much easier to just use the base library rather than trying to emulate a SAPI to load a PHP module. If you still want to go down this path, then reading the manual section about creating PHP modules will give you an insight into how this process works.

Re: [PHP] Reuse PHP functions in a third-party application
Richard, Thanks for the info. Under these circumstances I suppose that the CGI calling mode is the best suited. On the other hand this option might raise some performance penalty. I wonder if better performance could be achieved if I would use a socket based call interface to my module running inside the running PHP server.

I suppose that Prioblender thingie or one of the compilers might be able to be hacked with a PHP CLI binary to kind of do that, but a base PHP install doesn't ever actually store the opcodes anywhere in a compiled form as you are imagining. Even the various Caches only store opcode, and not machine code/binaries, so you still need the Zend Engine to rip through and execute them somewhere somehow, I think.

No. It doesn't help in this case.
DOMDocument->saveHTML() method converts any non-ascii characters into
entities.
For example, if the dom document has the text node value of:
שלום
It converts the string to entities:
שלום
Although the string is already in UTF-8. The DOMDocument is already
initialized with version "1.0" and encoding "UTF-8", the php file is in
UTF-8, the xml file is in UTF-8 and got header.
Example:
loadXML("שלום");
$output = $dom->saveHTML();
header("Content-Type: text/html; charset=UTF-8");
echo $output;
?>
-thanks
Did you set the UTF8 format in the html_entity_decode function?
so your code would become:
loadXML("שלום");
$output = $dom->saveHTML();
header("Content-Type: text/html; charset=UTF-8");
echo html_entity_decode($output,ENT_QUOTES,"UTF-8");
?>
I'm not really sure about it, but i'm not using UTF8. Also have a look
at the comments under the html_entity_decode function, and at the
functions/comments of utf8_encode/utf8_decode.

It's __construct (double underscore).
PHP5 uses __construct
PHP4 uses the class name.
To support both:
class test {
// php5 calls this
function __construct()
{
echo 'do stuff here';
}
// php4 calls this
function test()
{
$this->__construct();
}
}
:D
To support both, i wouldn't even think about the PHP5 __Construct. I
would just do it like this:
class test {
function test()
{
echo 'do stuff here';
}
}

You have clearly never ever dealt with musicians. :-) They will not just accept the wrong capitalization. You will need to fix it. I'll hazard a wild guess somebody will complain about the uc_first solution, and for every complaint, you can count on 10 more who just shrugged it off, but it's still wrong. Well, then you are working for hours on implementing filters for special names, and then you still get a few names wrong... and then you did all that work for a few fixes.
