Cheers, Rob. -- Rob: When you're on a shared hosting account, they typically prohibit files being outside of the web root. Some do, some don't. For example, GoDaddy.com prohibits files outside of the web root while Parasane.net doesn't, at least my experience with my accounts. I'm simply trying to find the best method to hide sensitive information on a shared hosting environment. Thus far, it appears that .htaccess files are the safest bet, but I understand that nothing is certain -- every method has risks. Try accessing a .htaccess file that you have created - if you get a 403 or anything to that effect, you're safe. You might also want to try the same with .htpasswd and .htgroups (they'll likely be blocked as well, but better safe than sorry). That way you'll actually know if they're safe instead of just relying on our guesses about your servers.

Re: [PHP] Secure Communication?
On 29 August 2010 18:24, tedd t...@sperling.com wrote: Hi gangl: I realize that the problem stated herein has been solved by others, so I'm not claiming I've done anything new -- it's only new to me. It was a learning experience for *me* and my solution may help others. In any event, I've finished creating a method for establishing what I think is secure communication between two servers. I've written two scripts that run on different servers, which confirm communication between them via hard-wired urls and creating/writing/reading a url-confirmation file. The purpose of this exercise was to simply to keep database-access data (i.e., user_name, password, key to decryption) secret. However, the secret could be anything you want to keep secret -- secret being defined as no data residing on the server of concern while allowing that server access to the data when needed and under authorization. Here's what I've done -- I have two domains, namely webbytedd.com (the Master) and php1.net (the Slave) -- both domains reside on different servers. The domain names really don't matter, it's just that this method currently works between those two domains. Statement of Requirements: 1. The Master requires access to it's database. 2. The Slave keeps access to Master's database in it's own database. 3. It's required that access remain secret in the event that the Master is hacked. *The term access above is defined as database-access data, such as user_name, password, and key to decryption. Description of Method: 1. When the Master wants access to it's database, it first creates a url-confirmation file and writes a token to that file, which resides on the Master. I've used time() as the token, but the token could be any variable -- it really doesn't make much difference other than the value should be different each time. 2. The Master then sends a cURL request to the Slave via a POST where the POST variable contains the token. 3. The Slave when receiving the POST request from Master reads the token from the newly created url-confirmation file residing on the Master and then compares that token with the token provided by the POST -- if the tokens match, then the Slave returns the access to the Master. If not, the process fails. 4. After receiving access the Master deletes the url-confirmation file and continues with it operation. If the Master does not receive access then it deletes the url-confirmation file and exits. This method sounds simple enough and does several things. 1. There is no access stored on the Master. 2. While the Slave has access for the Master stored in its database, the access to the Slave's database is kept in an out-of-root (not open to the web) file. Note, in this case, this was not possible on the Master because the host did not allow out-of-root files -- but that is only tangential to the problem addressed here. 3. If a hacker did obtain access to the Slave database, then the hacker would discover the contents have been encrypted and only the Master has the decryption key kept in it's database. 4. If a hacker did obtain access to the code residing on the Master, then the hacker could not access the Master's database because the access data is recorded on another server (i.e., Slave). Furthermore, the hacker could not get the code to run anywhere else because the Slave's look-up URL for the url-confirmation file is hardwired to the Master address. 5. And lastly, all communication between both domains is done via https. Now, for the exception of both server's being hacked at the same time, what could go wrong? A) I wouldn't want to reinvent the wheel but would use SSL/certificates/something to that effect (it's a whole lot more secure than your setup), and B) there's nothing in this setup that secures you from someone hacking Master and just sucking out data from that machine.

When a URL appears in a medium other than the Web itself, people seem to prefer ``pure hostname'' URLs; i.e., URLs without any path syntax following the hostname. These are often known as ``vanity URLs,'' but in spite of the implied disparagement, it's unlikely that non-purist users will abandon this practice, which has led to the continuing creation of huge numbers of hostnames. IP addresses are widely perceived as a scarce resource (pending the uncertain transition to IPv6 [DH95]). The Domain Name System (DNS) allows multiple host names to be bound to the same IP address. Unfortunately, because the original designers of HTTP did not anticipate the ``success disaster'' they were enabling, HTTP/1.0 requests do not pass the hostname part of the request URL. For example, if a user makes a request for the resource at URL http://example1.org/home.html, the browser sends a message with the Request-Line GET /home.html HTTP/1.0 to the server at example1.org. This prevents the binding of another HTTP server hostname, such as exampleB.org to the same IP address, because the server receiving such a message cannot tell which server the message is meant for. Thus, the proliferation of vanity URLs causes a proliferation of IP address allocations. The Internet Engineering Steering Group (IESG), which manages the IETF process, insisted that HTTP/1.1 take steps to improve conservation of IP addresses. Since HTTP/1.1 had to interoperate with HTTP/1.0, it could not change the format of the Request-Line to include the server hostname. Instead, HTTP/1.1 requires requests to include a Host header, first proposed by John Franks [Fra94], that carries the hostname. This converts the example above to: GET /home.html HTTP/1.1 Host: example1.org If the URL references a port other than the default (TCP port 80), this is also given in the Host header. Clearly, since HTTP/1.0 clients will not send Host headers, HTTP/1.1 servers cannot simply reject all messages without them. However, the HTTP/1.1 specification requires that an HTTP/1.1 server must reject any HTTP/1.1 message that does not contain a Host header. The intent of the Host header mechanism, and in particular the requirement that enforces its presence in HTTP/1.1 requests, is to speed the transition away from assigning a new IP address for every vanity URL. However, as long as a substantial fraction of the users on the Internet use browsers that do not send Host, no Web site operator

I didn't think that once you include a file; any other file included also includes any earlier included files (if that makes any sence) I've always thought includes are local; I.e in order to use a function from another file explicitly include that other file. You're thinking about it from the wrong perspective. It's not a question of a file including another file into it's own space, it's a question of scope. If you're in the global scope, any file included will get included into the global scope. If you're in a local scope however, then other rules apply: variables in the file (that would normally be in the global scope if you just executed the file) will be in the local scope only, while classes and functions in the included file will be imported into the global scope. Also, require_once will require a file once only. Using it to require the same file again from anywhere else will fail to include the file - that's the whole point of _once.

When you look at it, that's kind of a problem, though... for instance (assume this had some PHP in the middle, and there was actually a reason not to just put this in HTML in the first place): Simple PHP: ?php echo 'html'; echo 'head'; echo ' titlePage Title/title'; echo '/head'; echo 'body'; echo 'pThis is the page body/p'; echo '/body'; echo '/html'; ? Output page source: htmlhead titlePage Title/title/headbodypThis is the page body/p/body/html Now, I can go through and add a newline to the end of each line (echo 'html' . \n; and so on), but it adds a lot of typing. Is there a way to make this happen automatically? I thought about just building a simple function, but I run into problem with quotes -- either I can't use single quotes, or I can't use double quotes. Historically, I've dealt with the issue by just having ugly output code, but I'd like to stop doing that. How do other people deal with this? Thanks, Alex Alex Just add a \n at the end as echo 'html\n'; That will not work. Single quotes means that the '\n' is not interpreted as a new line so you'll see a bunch of '\n' in the output. What I sometimes do is: $out = array(); $out[] = 'html'; $out[] = 'head'; $out[] = ' titlePage Title/title'; $out[] = '/head'; $out[] = 'body'; $out[] = 'pThis is the page body/p'; $out[] = '/body'; $out[] = '/html'; echo join(\n,$out); Interesting. I hadn't thought of that, but it could work. It'd still be quite a bit of extra typing, but at least I find it more readable... Ash already mentioned it: heredoc format. Much easier, less typing, easier to read, keeps formatting, etc, etc etc. Regards Peter -- hype WWW: http://plphp.dk / http://plind.dk LinkedIn: http://www.linkedin.com/in/plind BeWelcome/Couchsurfing: Fake51 Twitter: http://twitter.com/kafe15 /hype -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

So the failure is recent and I just can't figure what changed. David Browsers treat newlines as any other whitespace - so print_r and var_dump will not, on their own, provide you with a linebreak in a browser. If you've got xdebug installed, var_dump will provide a nicer output (including line-breaks). However, by far the easiest way to check if you're actually getting linebreaks in your output is checking the source. If you're suddenly experiencing a change in output, then some of your environment variables have changed - hard to say which one without knowing more about your system, but you must obviously have changed/updated something for this to happen.

As far as I'm aware, the first of the two will be faster, but
only just.
As Saeed mentioned, the difference will be negligible, and unless

plan to run a line like that in a loop or something hundreds of
thousands of times, you probably won't notice any difference.

to be proper, shouldn't it technically be
$c = {$a}{$b};
It doesn't have to use the braces. The braces only tell PHP exactly
where to stop parsing the current variable name. The following
examples
wouldn't work without them:
$var = 'hello ';
$arr = array('msg 1'='hello','msg 2'='world');
echo {$var}world;
echo {$arr['msg 1']}{$arr['msg 2']};
Without the braces, in the first example PHP would look for a
variable
called $varworld, and in the second it would be looking for a simple
scaler called $arr, not the array value you wanted.
Ash:
I understand what the {} does, but just like in HTML, it is more
proper
to use lower case for the attributes/elements, and use (double
quotes)
when wrapping the attributes... but is it not REQUIRED to write it
in
that manner... just like it is not required to wrap the variables in
{}
when inside the ...
that's just me, I tend to try and do that every time...
XHTML requires both lower case and double quotes. So if that may be in
your future, you should be using both already.
I don't know about HTML 5. Since that spec is still years away from
completion and hasn't added anything we can make use of, we haven't even
bothered to look at it.
Where exactly do you get the part about double quotes from? Can't seem
to locate it in the any of the relevant specs (xhtml or xml). Also,
never seen an xml or xhtml validator choke on single quotes.
As for html 5, it's in use today already. Big parts of it are unlikely
to change, so there's little reason not to start using it.

I am working on a small system where I am both trying to avoid code duplication and at the same time I am trying to keep the presentation logic separated from the application logic. I am using sessions and are avoiding headers already sent problem by keeping the HTML out of the application. For example, I would like to have a common header.php file, but it is difficult to create this since one file needs to have some specific Javascript located in the head /head tags, but the other files doesn't need this. Another file needs to have a specific onload call in the body tag, while yet another file also needs to have an onload call, but with different attributes. I have been looking around in other systems to see what kinds of solutions are being used - as inspiration. I have been thinking about the following solutions: 1. Create only ONE header.php file that contains a lot of conditionals depending on what file is including it - the output of HTML/Javascript changes. I believe this would turn into a very ugly hack. Difficult to maintain. 2. Create a HTML generating class with a set of methods that each contains an adequate amount of parameters. Each method maintains its own HTML tag. For example, docType($type) would generate the doctype specification. I believe this is a cleaner solution, but the problem with code duplication isn't avoided. Some of the presentation logic contains conditionals and the HTML changes when the conditional changes, hence the header content changes, but the doctype, html, and head doesn't necessarily change and they would get duplicated a couple of times in some files. 3. Avoid the problem all together, use output buffering and completely forget about separation between application and presentation. I hope I make sense. Any thoughts on these kinds of problems? sounds like a job for smarty http://www.smarty.net/ I've used smarty and it's nice. How does Smarty solve this problem? Just curious.

[PHP] DOMDocument/DOMElement problem
I'm currently trying to parse a document with DOMDocument, and I'm having some serious problems. I created a script that runs fine on php 5.2.9, ripping out content using DOMNode::nodeValue. The same script fails to get any content on php 5.3.3 - even though it correctly navigates to the proper nodes to extract content. Basically, the code used looks like this: $dom = new DOMDocument(); $dom-loadHTML($data); $dom-preserveWhiteSpace = false; $xpath = new DOMXpath($dom); $nodelist = $xpath-query($query); $value = $nodelist-item(0)-nodeValue; I've checked to make sure that item(0) is in fact a node - it's there and even of the right type (a td - table cell), but nodeValue is empty. The script works on some documents but not others (on 5.3.3 - some checking suggests a doctype of xhtml might be involved in the problem but I tried ripping the doctype out and had no difference) - on 5.2.9 it works on all documents, returning the proper nodeValue. Am I missing something basic?

Not to mention that it has nothing to do with a procedural autoloader.

That is probably one of the areas where care should be taken in WHAT you are caching. CURRENTLY too much caching goes on I have not seen this problem but I have often seen sites not caching things they should, so I'd say you're wrong. I don't think its relevant one way or the other though. memcache may well be a candidate to use for a cached list of choices for a form, but on a distributed database ( such as Firebird ) then how do you KNOW if the list has been updated? This is relevant to very few developers. Much more relevant is the overhead used in contacting the single mysql/postgresql/etc database that your provider put on another machine. Only the database actually knows that, and a good database will provide ALL of the data caching that you need ... or at least it should if the DATABASE is designed correctly. See above. The reason for 'caching' needs to be understood before it is applied in order to avoid the black holes that random caching is causing nowadays already. How often do you hear wipe the xxx browser cache? And I know if I am changing theme elements in bitweaver or phpgedview then I HAVE to wipe the cache to ensure that smarty rebuilds the relevant pages. Which underlines my point: caching is not icing on the cake but should be thought of sooner in the process, contrary to Tommys point.

Personally, I'd use something like:
if($hits 10) {
$top = 10;
} else {
$top = ($hits[0] + 1) * pow(10, strlen($hits) - 1);
}
Basically, add one to the first digit and make the rest of the digits 0.
Depending on how you want to handle the cases ending in 0s, you may want an
extra check in there.

Personally I'd add a percentage on top, say 5 or 10 percent.

Hi folks,
With the recent thread about password security, I wrote a small quick

including upper case, the script seems to consumes more memory (shown in

Could someone please tell me why the above code consumes additional memory
as time progress for the execution of the while loop? Researching PHP GC

Re: [PHP] Global or include?

But if you are absolutely sure that all scripts will be processed, you can include it only in one of them, because PHP - in short terms - does a file include, so it will look like as the included file is part of the script. The global keyword does not do what you think, it only propagates variables between functions without passing them as parameters. In general, you ought to avoid using global, because it can make your script less readable, and / or can lead to logical errors. Because I am OOP fan, I'd rather create a static class, using public static fields, so you can reach those variable as like ConstClass::MyConstant. In that way, you have the advantage of simply create new constants, and it doesn't matter how many times you include this file, there will be only one instance. If you include the file several times, you still have the problem of redeclaring the class, so you'd have to wrap the definition in a conditional, which sucks, or use the *_once functions and incur the overhead. Much better to be in control of the includes. Apart from that, it's generally better to use require* instead of include*. If the file is needed, don't continue without it, as the consequences will be unknown. SanTa 2011.01.05. 23:40 keltezéssel, Paul Halliday írta: Say you have 10 or so scripts and a single config file.

How often would this profiling have to happen? Seems to me that if it's a once per build or once per someone pressing the button, then go for the more expensive analysis checking through the files. Just build up a tree that shows which classes implement what or inherit from where, save that along with file modification times, and if you have to redo the analysis (on a running system, for instance) then just check files that have changed since last check.

Microsoft is working hard behind the scenes to block it unless it only allows their codec's behind the video and canvas tags. (Their efforts are very reminiscent of their sabotage of ISO with the OOXML specification.) From a recent announcement(*), it appears that even the committee has given up ever having a usable consensus, but will accept whatever the browser developers want to implement even if they are incompatible with other browsers. That's not a standard. Html 5 has a fair chance of not being completed (that's going by what Ian Hickson has stated as well as reading blogs and such on the matter - see http://en.wikipedia.org/wiki/HTML5 for a pointer or two). That's besides the point, though: html 5 *is* where the web is headed, as opposed to xhtml. In part this is happening by browsers implementing features piece by piece as they become stable - hence, you can already use some html 5 features and be rather certain they'll work as expected later on. MS may hate things not working how they like it, but big and stupid as they are they have in fact figured out that the web will happily move on without them - so they'll get round to implementing html 5 features as well, at some point, even if it doesn't use their proprietary code.

I'm not sure what you're saying here, Peter? Are you saying that the code
wouldn't detect if $z was set to NULL by the calling code or by the default?
I believe the point would be that no matter the case, the check would still
perform the same task.
Maybe I misunderstood (sorry.)
The point is the poster seemed to suggest the safest way to use
optional parameters was to use null as the default value and use ===
null to check against the optional parameter - as a way to check if
anything was passed in or not. I just pointed out that that would fail
to check for a null passed in and that func_get_args() would be a
better match. You're obviously right that the check inside the
function would work the same whether null was passed in or the value
was defaulted to null.
That said, if you're making use of optional parameters and need to
check if anything was passed in, you're almost certainly doing things
wrong.
I sometimes use this approach. PHP doesn't to my knowledge allow you to use
function calls within defaults. There are times that I want the default to
be the result of a function, and to accomplish this, I'll often set the
default to null, then check for the null and carry out the function within.
Is there a better solution?
As noted in the post, func_get_args will show any and all (at least on
my 5.3.3 install and 5.2.6 install) values passed in to the function -
hence it will also show if no parameter was passed in (and is thus
safer than relying on the default value).
That noted, I don't think checking if a value was passed in is good
design - I think the function should be ignorant of what is passed to
it. But that's just me :)

Peter

that doesn't work (as it doesn't detect NULL passed in). Use
func_get_args() as that gives you any and all arguments passed to the
function, excluding defaults.
This must be my week to make enemies.
I beg to differ. If the user passes in NULL for $z or passes in nothing
for that variable, it does in fact show up as NULL. The following test
code works as indicated:
Did anyone say it wouldn't?
The responses in the first and third cases are NULL. You might be able
to argue that in the first case, where the user passed in NULL, it's
not the same as if the user passed in nothing. But I would assume that the
author considers NULL a signal value, such that if the user passed such
a value in, it would be equivalent to not passing a value for the third
parameter.
The point I was trying to make was specifically that someone might try
to distinguish whether a value was passed in for an optional parameter
or not (like the case Adam outlined). Relying on the value of the
optional parameter will not do, in that case (well it might, depending
upon how stringent you really need to be).
That said, if you're making use of optional parameters and need to
check if anything was passed in, you're almost certainly doing things
wrong.
Again, assuming you're talking about examples like the one above, I have
to disagree. Presumably, passing in an optional parameter changes the
action inside the function. Thus, you would *need* to test for its
presence. Otherwise, you would be stuck with assuming it's there,
attempting to use it on that assumption, and dealing with whatever
errors it causes when-- surprise!-- it's not there.
You should be wary of assumptions, they're not really working out for you.
- a) you're not addressing Adam's use case
- b) I wouldn't need to test for any presence if I wrote the function
as I would personally prefer, i.e. not trying to test if any value was
passed to the function or not. That's the whole point of optional
values: even if nothing is passed in, there's a default value. That's
why trying to check if something was passed for the optional parameter
is counter-productive: the idea of the default value is that you
shouldn't have to check.

Peter

The pattern I made was to work in cases where the page is
non-compliant to any of standard W3.
Not entirely sure what your input data is, as I'm guessing one or more
mail programs may have added line breaks. When I run the code I get no
matches at all - so I'm guessing you might have different input on
your end. More specifically, I'm also guessing you have line breaks on
your end, but not equally distributed - which would explain the one
hit.
Apart from that, there are a couple of things I'd rework in your regex:
%a\s+.*?(?!href)\s+href\s*=\s*([^\s\']+|\'[^\']+\'|\[^\]+\)[^]*(.*?)/a%ims
* added modifier to whitespace at first
* allowing for any character not followed by href (non-greedy)
* match the href
* use proper alternation
* capture anything inside the a tag, non-greedy
* match with a closing /a tag

Re: [PHP] is there a static constructor?
On 31 March 2011 06:56, D. Dante Lorenso da...@lorenso.com wrote:
All,
I want to build a config file class that gets called statically. Is there
such a thing as a static constructor? Example:
class Daz_Config {

public static function get($key) {
self :: load();
...
}
}
Daz_Config :: get('myvalue');
I want to call the load function when the class is used for the first time.
If no code ever calls Daz_Config :: get(...) then I never want to invoke
load() but if it does get called, I only want to call load() once before the
class is used further.
Anyone know how to do this with calling load() at the top of all the other
functions and writing a load() function that exits early if already loaded?
The concept doesn't really make sense - a class that never gets
instantiated never gets constructed, hence no static constructor (nor
a static destructor). You'll have to call your constructor function
at the top of the static methods you'll be using - just check inside
the constructor if it's been called before or not.

Re: [PHP] XML... Useful or another layer of complexity?
Like every other technology, XML needs to have a use before it becomes a useful tool. Just using XML because it's available quickly leads to headaches, as it isn't the best tool for all scenarios (config files written in XML for instance). That said, XML is awesome for a lot of things ... however, without having a better grasp of XML you're unlikely to know whether it'll fit your needs. If for no other reason, learning XML and related technologies is worth it simply because the rest of the world uses it. So get to know it, then you'll be able to actually judge if your project can benefit from it.

Here's some more sample code, then:

query)
}
$records = retrieve_records($condition);
$recordlist = array();
foreach ($records as $record) {
array_push ($recordlist, $record)
}
I know this code isn't very useful, but these are the conditions which cause
the issue I've mentioned.
class a {
public function __construct() {
$this-rand = mt_rand();
}
}
function retrieve_records () {
return array(
new a,
new a,
new a,
new a,
new a,
);
}
$records = retrieve_records();
$recordlist = array();
foreach ($records as $record) {
array_push ($recordlist, $record);
}
die(var_dump($recordlist));
gives me:
array(5) {

[rand]=
int(1375725959)
}
[4]=
object(a)#5 (1) {
[rand]=
int(100662005)
}
}
I'd say there's a problem in your code. Check where you might be using
references, chances are you're using one somewhere and not unsetting
it afterwards.

So I've added my own error handler, but it seems that I can't catch fatal errors. The error in question comes from doing something like: Fatal errors are fatal - if you could recover from them, they wouldn't be fatal. $res = $dbh-query ($sql); with $sql being an SQL statement, and $dbh being a database handle. I recently had a case where $dbh was NULL, which triggers a fatal error from SQLite. In principle such a bug should show up quickly, but this one had lain untriggered for about a year. It seems to me somewhat arbitrary for this to be designated a fatal error. Is there a way I can catch these? Most SQLite error situations I'm solving with try/catch but no luck with this one so far. You've got something wrong: either $dbh is not null or the error is not from sqlite. I'm guessing the former. To avoid situations like that, do proper error checking (i.e. actually check that your database connection was opened succesfully). Error handling in library packages seems somewhat arbitrary - e.g. opendir may give an E_WARNING, but closedir, readdir don't. You can avoid all problems with error output by turning off error displays in php.ini (set display_errors = off) - use error logging instead. That's the recommended setting for production servers.

I've tested this by introducing some errors (e.g. unitialised variables or setting $dbh to null) and these are all nicely picked up. You were trying to call a method on a non-object - how do you expect PHP to handle that if not with a fatal error? Anyway, good to hear you solved the issue - I misunderstood what you wanted to do (shut down in a proper fashion, not actually recover from the error) so I didn't think to mention this. * snip * You can avoid all problems with error output by turning off error displays in php.ini (set display_errors = off) - use error logging instead. That's the recommended setting for production servers. This is not a browser/webserver situation in the classic manner.

You can call it production server or not, if you are having problems with error messages from php then you should turn off error display - which shouldn't get in the way of you showing your own error messages but will solve the problem mentioned.
