[PHP] Nagios Monitoring

2009-04-13 Thread Waynn Lue

Hey guys,

I'm looking to write a nagios plugin that essentially monitors whether or
not a database query returns a value > 0 at any given point.  I was hoping
to write this in PHP, but I haven't found too many examples of Nagios
plugins in PHP (
http://www.barryodonovan.com/index.php/2007/11/02/asterisk-pri-nagios is the
best one I've found so far).  Just wondering if anyone has any experience
writing them?

The problem is that validating xhtml does not necessarily render 
properly in some browsers *cough*IE*cough*


That's why I prefer to send html 4.01 to those browsers.

Would this function work for sending html and solve the utf8 problem?

function makeHTML($document) {
   $buffer = $document->saveHTML();
   $output = html_entity_decode($buffer,ENT_QUOTES,"UTF-8");
   return $output;
   }

I'll try it and see what it does.

Huh - not tried above yet - but with

$xmlBody->appendChild($test);

both saveXML() and saveHTML() do the right thing.

However if I have the string

שלום

and load it into a DOM -

With loadHTML() the utf8 is lost regardless of whether I use saveXML() 
or saveHTML()


With loadXML() the utf8 is preserved regardless of whether or not I use 
saveXML() or saveHTML()


php 5.2.9
libxml2 2.6.26-2.1.2.7 (CentOS 5.3)

I wonder if the real utf8 problem people experience is really with 
loadHTML() and not with saveHTML() ??

Go to http://www.clfsrpm.net/xss/dom_script_test.php

The page was meant to test something else but enter some UTF-8 into the 
textarea (well formed xhtml) -


With IE - html 4 is the only thing it will output but with FireFox and 
Opera, by default it outputs xhtml but you can check a box to force html.


When it outputs html it uses saveHTML()
When it outputs xhtml it uses saveXML()

The source is linked there so you can see.

Anyway - it looks saveHTML() works fine with UTF8 as long as loadXML() 
was used to load the data.


I've tried both Hebrew and Polytonic Greek.
It outputs correctly regardless of html or xhtml - but only after I 
changed the code to load the textarea as xml opposed to html.

I'm not a nagios expert but as far as I know a plugin can be anything
executable that returns the necessary values. So basically you could
just write a php script and make it executable with

#!/path/to/php

write the script here

You can find more information how to use the php cli here:

http://php.net/features.commandline

And here you can find the needed return values:

I hope this helps!

Like that? If your array is associative you can drop the $lastIndex calc

Thanks for the suggestion, Mark. I've already experimented with count;
you're close, but there is still a small glitch and that's in count();
foreach doesn't give a damn about count so you can't use that - it is
reset once inside the foreach loop. And, the "as $index" cannot relate
to the $lastIndex because the array index (which would be the index in
the "as $index") can be any number and is not sequential. There are a
couple of other ways, one is suggested by Jim Lucas in the thread
"extract varying data from array with different formatting"; another is
to change the SELECT query to use a ranking reference - I think it may
be a bit more complex, though.
Any other thoughts? ;-)  I'll appreciate them.

Re: [PHP] what to use instead of foreach

2009-04-13 Thread PJ

Hi Leon,
Thanks for the suggestion; I'm quite new to all this, so it's a bit
complicated for my peanut brain.
I have already tried with several count and for schemes. None work
because foreach ignores any counters once in the loop. Also, this
foreach is nested within another foreach; don't know if that affects
anything.
I'll try to understand the second suggestion using for. I'll see what
comes up.
There are actually several conditions that have to be met:
1. if only 1 author = echo "author"
2. if 2 authors = echo "author & author1"
3. if more than 2 authors = echo "author, author1, author2 & author3"
That's what makes it a "toughie"

Your example kind of defeats the point.  The point of a try {} block is 
that it will attempt to execute code and execute catch on a true 
failure.  Your function already is protected against failure.


Consider this

$x = 0;

try {
   $y = 4 / $x;  // This will divide by zero, not good.
} catch (Exception $e) {
   echo "Error: $e"
}



More importantly, the try/catch should be in your function, not around 
the invocations of your function:


function inverse($x) {
try {
return $x/0;
} catch(Exception $e) {
return false;
}
}


Consider this also, simply echoing an error on divide by Zero might not 
be great if your function is called, say, before headers.  Throwing 
exceptions can be re-caught by executing code, which can easily avoid 
pre-header output.


Does that clear up the purpose a bit?  I'm no expert, but that's my 
understanding.

Kyle

Yes and No...
Right now I was thinking to start using try/catch block on places where could 
be problem in my code and, if there is an error - send to myself email with 
error info.
E.g., I use right now something like this:

function send_conf_email($to, $subject, $content)
{
  $headers ="MIME-Versin: 1.0\n" .
 "Content-type: text/plain; charset=ISO-8859-1; 
format=flowed\n" .
 "Content-Transfer-Encoding: 8bit\n" .
"Reply-To: \n".
 "From: LL\n" .
 "X-Mailer: PHP" . phpversion();

mail($to, $subject, $body, $headers);
}

function send_error_email_to_admin($email)
{
$to = 'l...@yahoo.com';
$subject = '[Error Report] '.$email['subject'];
$content = $email['content'];

send_conf_email($to, $subject, $content);

}

if (!send_conf_email($to, $subject, $content))
{
   send_error_email_to_admin($subject, $content);
}

how would/should be the code by using try/catch() block? something like this:

try
{
if (!send_plain_email($this->submitted_email, $subject, $body_plain))
{
throw new Exception('Confirmation email is not sent');
}
}
catch (Exception $e)
{
send_error_email_to_admin($subject, $content . $e->getMessage());
}

there is something "fishy"

There *are* encoding options when you setup the domdocument so it

Re: [PHP] Generate XHTML (HTML compatible) Code using DOMDocument

2009-04-13 Thread Michael Shadle

I will say though this negates the reason I chose to use domdocument  
to begin with. I am feeding it snippets of HTML that usually do not  
validate and I am not sure I want to run it through tidy first to  
convert from HTML to XHTML to run the domdocument and then convert it  
back... I am essentially using this to traverse the DOM and process  
all a href and img src attributes for a link remapping job. (also  
realizing the power of php's DOM for other things I used to try tidy  
and then use simplexml when doing HTML scraping ...) but php's dom  
allows me to give it absolutely crappy HTML and it still works.


However if someone has a nice regular expression or chunk of code that  
allows you to scan a doc for a href and then replaces them in the  
proper context (not just globally) that would work too. I can't just  
blindly find urls and then replace them (although the reason for this  
escapes me right now)

this was the only workaround I received for the moment, and I was a
bit afraid it would not process the full range of utf-8; it appeared
on a quick check to work but I wanted to run it on our entire database
and then ask the native geo folks to examine it for correctness.

Re: [PHP] Generate XHTML (HTML compatible) Code using DOMDocument

2009-04-13 Thread Raymond Irving


Hi Michael,

Your script works fine. The only problem I'm having is that it does not support 
html entities. 

The following code will cause the page to crash:

©

I think that's because you're using loadXML and not loadHTML.

Has anyone from the dev team contacted the libxml guys about the utf-8 issue 
with loadHTML()?

/path/to/test2.php on line 18 

any help or suggestions would be very much appreciated. details follow.

Re: [PHP] try - catch is not so clear to me...

2009-04-13 Thread Marc Steinert

Basically try-catch gives you the ability to handle errors outside a class or method scope, by the 
calling instance.
This comes in handy, if you are programming in an object orientated way and thus enables you to 
seperate error handling from the rest of your functionality.
Means, your methods do only the things, they are meant to do, without bothering to handling occuring 
errors.

Hope, that made things clearer.

RE: [PHP] what to use instead of foreach

2009-04-13 Thread Leon du Plessis

Hi PJ, 

Ok, If I understand correctly you can attempt to alter your code as per
following example (I am breaking it down a little for readability):

a) If you only wish to output the authors, see also Mark Kelly's example,
You can simply output as many authors you have associated (you will need an
associated array!!:

Or b) I include the following alternative example:

$string_out = "":
Foreach ($my_titles as $titles)
{
   Echo "Title: $titles By:";
   Foreach($my_authors[$title] as $author)
  $string_out .= "$author, "; /* Building string */

   // Add 
   $string_out .= "";

   // Here you would replace your last comma with the "&" you want
   // There are a few ways to do this (like Mark Kelly's), but will try 
   // another way (older, maybe less complicated?).
   $final_string = substr($string_out,0,strrpos($string_out,",") - 1);
   $final_string .= " & " . 
  substr($string_out,strrpos($string_out,",") + 1);
}

So all you need is to modal your data around this, and you should be fine. 
You could construct your arrays then as follows as an example:

$my_titles = array("title1","title2");
$my_authors["title1"] = array("a someone","a notherone");
$my_authors["title2"] = array("mr. a","mr. b");
... 

and so forth...how you construct the data is then very important as you can
then later use it simplify your coding as you progress and as demonstrated
below:

In future, where the need justifies it, you can construct your array to
already contain the needed string you want to output, it may help, but you
will sometimes have the same effort in constructing the data for the arrays,
so it is up to you to decide which approach is going to be best: e.g.
$my_titles = array("title1","title2");
$my_authors["title1"] = array("a someone, a notherone & Mr. X");

Then you can simply echo the array value:
echo "$my_authors["title1"] . "";

Hope it is enough info for to work on for now!!

Have fun!
Leon

Hi Leon,
Thanks for the suggestion; I'm quite new to all this, so it's a bit
complicated for my peanut brain.
I have already tried with several count and for schemes. None work
because foreach ignores any counters once in the loop. Also, this
foreach is nested within another foreach; don't know if that affects
anything.
I'll try to understand the second suggestion using for. I'll see what
comes up.
There are actually several conditions that have to be met:
1. if only 1 author = echo "author"
2. if 2 authors = echo "author & author1"
3. if more than 2 authors = echo "author, author1, author2 & author3"
That's what makes it a "toughie"

Re: [PHP] what to use instead of foreach

2009-04-13 Thread PJ

Hi Leon & thanks.
It sure is complicated. Jim Lucas example did the trick very nicely (in
my other post -
"extract varying data from array with different formatting" but here I
am learning about other ways & means.
Redoing the arrays means redoing the queries :-(  but I'll have a go at
it if I'm to learn anything. I already have a ranking column set up but
am not using it at the moment for the author display. Anyway, I have
enough to keep my neurons busy for a while.
Thanks.

You know, this is the first explanation of exceptions I have seen that
actually makes sense. I could never figure out what they were and why
they were. It always looked like it was just a special subset of errors,
a distinction without a difference, as it were. But looking at them as a
technique to move the handlers out of the mainline code actually shines
some real light on the subject.

[PHP] multi-dimensional arrays

2009-04-13 Thread Andres Gonzalez


Hi,

I am learning PHP and have a simple question.
I have a input string in this form:

xxx    xx  x  xx   xxx
xx  x   x  xxx  xx  xx
.
.
.
xx  xxx  xx    xx   xx

each line has 6 words of various lengths, all separated by white space.
the input string can have any number of lines

I want to put this into a multi-dimensional array, each line an array 
that is an element of an outer array.


I have tried various ways to do this--I have used explode() and 
array_filter() and can get a single line parsed and into an array but I 
am having problems getting a well formed 2 dim array.


What is the easiest way to do this? With all of the PHP array functions, 
there should be an very straight forward way to do this.


Any help would be appreciated.

-Andres

Well in your approach you get a bunch of empty elements where the spaces
are.  Here are two ways but I'm sure one preg_match_all() without the
explodes and loop could do it (some guru will show us):

//one way
$text = 'xxx    xx  x  xx   xxx
xx  x   x  xxx  xx  xx
xx  xxx  xx    xx   xx';

$lines = explode(PHP_EOL, $text);

foreach($lines as $line) {
$temp = explode(' ', $line);
$result[] = array_filter($temp, 'reduce');
}
function reduce($var) {
return !empty($var);
}
print_r($result);

//another way
$text = 'xxx    xx  x  xx   xxx
xx  x   x  xxx  xx  xx
xx  xxx  xx    xx   xx';

$lines = explode(PHP_EOL, $text);

foreach($lines as $line) {
preg_match_all('|([^\s]+)+|', $line, $matches);
$result[] = $matches[1];
}
print_r($result);

[PHP] Re: multi-dimensional arrays

2009-04-13 Thread Joï¿½o Cï¿½ndido de Souza Neto

I think the best way would be:

$arrays = explode(PHP_EOL, $field);
foreach ($arrays as &$array) {
$array = explode(" ", $array);
}

Not tested, but should work.

i use apache 2.2.x so i'd guess the answer would be no. but i'm not sure.

After assigning the string do

$string = preg_replace('/\s+/',' ',$string);

Then you should be able to do the two explodes.

RE: [PHP] $_GET verses $_POST

2009-04-13 Thread Daevid Vincent

Just to clarify. Obfuscation is NOT a substitute for security. While I don't
disagree with the "when's" here of GET vs POST, this statement is a bit
misleading... 

Any cracker worth his salt can easily install any number of Firefox
extensions or unix command line tools and not only view the POST data, but
alter it as well. So if you are sending something like a password, don't
think that it's "secure" just because Joe Average doesn't see it. If you're
not using SSL, then it is sent as plain text like everything else.

And don't assume that what you presented on a web page in select boxes and
other form elements is the ONLY thing that is going to come back to your
server to process. It's trivial to mangle the data. This is what SQL

It also should be noted that post is not automatically secure against 
csrf attacks. While most csrf attacks are get, they can and do happen 
via post as well.


I agree that passwords need to be sent via SSL.
Unfortunately most users use the same login and passwords for many 
sites. So even if your site doesn't otherwise need SSL, using SSL for 
login helps protect your users.


For me the biggest advantage of post is the URLs aren't ugly.
For cases where get with a variable in the URL is useful (IE 
product=BluePhone) - I prefer to handle that via mod_rewrite.


The requests get handled by generic.php and generic.php then looks at 
what the requested URI is to figure out what otherwise would have 
specified by a get.


Just as linkable as ?get=whatever and a lot prettier for the user to 
look at in the url bar.


I think doing it that way also has search engine indexing advantages.

i use GET when i want the user to be able to email the link to someone,
mention it on a blog or bookmark it and it will always yield the same page.

i use POST if submitting the form causes any change in the database or
session data (as required in the HTML standard) or if i want to hide the
mess of posted data from the user (they wouldn't be happy to see personal
details in the address bar after filling in, say, a user registration form).

if there's a grey area between these two, i'm not able to think of an

now we've gotten into aesthetics.

RE: [PHP] linux console on the PHP

2009-04-13 Thread dhorton

I am sorry if I don't understand quite what you are after.

Answer A:
If you want a console connection to a server (e.g. engsan01 as below), then
you could use a TELNET URL which is still supported in various browsers.
This doesn't require PHP, but could be embedded in the HTML part. 

engsan01:23

I have my telnet client as just the windows default client which doesn't
support secure connections. If you have a better SSH-aware client then perhaps
engsan01:22


Answer B:
If you want to execute commands from a web form then you presumably want
to use the "system" function with commands read from form
http://www.php.net/manual/en/function.system.php
Probably pretty insecure

Answer C:
If your client is on a local network and has X, then use system to run "xterm
-display clientip:0"
I think clientIP will be available on one of the $_ENV variables.

your answer lies with not replacing foreach to make your life/output
better.  But with how the data is prepared and handed off to the
foreach statement.

I am guessing that what you want would be something like this.

Since this looks like a snippet of code I sent you the other day, I
will snag it "complete" from the other thread.

 $authorData ) {
# Add all the authors to that new array
 $aList[] = "{$authorData['last_name']},
{$authorData['first_name']}";
}

# Sanitize the output
$aList = array_map('htmlspecialchars', $aList);

# Get a count of how many authors their is.
$tAuthors = count($aList);

# If more then one, do...
if ( $tAuthors > 1 ) {
# Take the last one off, so we can handle it differently
$last_author = array_pop($aList);
echo join(', ', $aList), ' & ', $last_author;

# If only one, then do...
} elseif ( $tAuthors == 1 ) {
echo join('', $aList);
}
echo '';
} else {
echo 'No authors found';
}


...

?>


Hi Jim,
Please excuse my writing to you directly. If you don't think it's
proper, just let me know & I'll swing off.


No problem with hitting me directly, but your findings could be of use to others
since it is cleaner way of solving your problem.

So, on the list we go


So, while I have your attention and if you have a moment, I found this
interesting possibility: someone threw "implode()" at me and I looked it
up in the php manual and hey, found and interesting little function:

function ImplodeProper($arr, $lastConnector = ' & ')
{
  if( !is_array($arr) or count($arr) == 0) return '';
  $last = array_pop($arr);
  if(count($arr))
return implode(', ',$arr).", $lastConnector $last";
  else
return $last;
}

Since my limited understanding of php impedes me to implement it
experimentally in my application, I was curious if, indeed, it could be
another option. It does look to me like it could work, but it would
require a slightly different implementation of the query, probably
somehow using something like a CONCAT(first_name, " ", last_name). Am I
learning something here or is this the wrong tree to bark up?



This would be a very nice way to clean up the code

Although you could do something with CONCAT(), I would suggest leaving the code 
as is.

Data is all that you want to get from MYSQL, not format.

Basically, take the above function and place it in a lib you include
for everything.  Then replace the if/then/else statement that I built for you 
with a
call to said function.

 $authorData ) {
 # Add all the authors to that new array
  $aList[] = "{$authorData['last_name']}, 
{$authorData['first_name']}";
 }

 # Sanitize the output
 $aList = array_map('htmlspecialchars', $aList);

 echo implodeProper($aList), '';

 } else {
 echo 'No authors found';
 }

...

?>

That would do the trick.

[PHP] Logging out of a SSL / https:// site using PHP? (or JS?), Client Side Cache

2009-04-13 Thread scubak1w1

Hello,




I have a series of web sites which use https:// authentication (using AD 
integration to 'check the credentials' as it were) - all seems to be working 
well..

I have been Googling et al. for a way to log the user off the site 
"fully"...


I can do a series of things on the server side per Dreamweaver's Server 
Behaviour / User Authentication | Log Out User, etc - but the client's 
browser cache (?) still keeps the credentials, and so ifthey return to the 
site (say, with their back button) they can get right back in... the only 
sure fire way that I can see, simply, is to close and reopen the browser.


Any thoughts on how to clear the user's browser's cache of a https:// site's 
credentials and then send them on to a non-secure page?


I thought of:




  a.. closing and reopening the browser with some JS, if this is indeed 
possible - buT I would need to somehow keep track of what other pages the 
user had open, their security settings might now allow it, the user would 
likley get annoyed, etc, etc


  b.. "forcing" a 401 or 403 - but my attempts at 'coding' this were 
unsuccessful - and also how do you get the page to redirect on to something 
like www.adobe.com or something (because seeing a 403 'standard page 
message' would likely be "alarming" to the average user


  c.. I have some code in ASP that will do this, but the user would be have 
to be limited to using Internet Destroyer  -ugh!  :-)



Thanks In Advance:

GREG...

[PHP] https and Credit Cards

2009-04-13 Thread Skip Evans


Hey all,

I've always put any forms that collect credit card information 
behind a secure connection, https, figuring that sending that 
information from the client browser to the server should be 
secure, but I'm having convincing a client that it is necessary.


He instead insists that only the call to the credit card 
processor's server needs to be secure and of course the 
processor supplies the connection there.


But doesn't also the form need to be secure since you're 
sending CC information from that form back to the web site's 
server?


That's what I've always assumed.

I need some opinions on this, and if I'm right I think the 
client will defer to a few more votes.

Re: [PHP] try - catch is not so clear to me...

Subject: Re: [PHP] try - catch is not so clear to me...

Basically try-catch gives you the ability to handle errors outside a class or 
method scope, by the calling instance.
This comes in handy, if you are programming in an object orientated way and 
thus enables you to seperate error handling from the rest of your functionality.
Means, your methods do only the things, they are meant to do, without bothering 
to handling occuring errors.
Hope, that made things clearer.

Looks like I still didn't get it correctly:

try
{
if (!send_confirmation_email($email, $subject, $content))
{
throw new Exception('Confirmation email is not sent');
}

}
catch (Exception $e)
{
send_email_with_error_to_admin($e, $content);
}

why am I getting both emails? I'm receiving confirmation email and email with 
error message - that I'm supposed to get if the first one is not sent for some 
reason?!?!?!?

thanks for any help.

You're absolutely right, no question, and for exactly the reasons you
give. The path back to the server from the client is unencrypted if you
don't use https, and the credit card information is in the clear when
transmitted.

In fact, if I were a hacker and found out that you were doing this, I'd
make it my business to hijack that connection so I could transparently
capture credit card information. I mean, for a hacker, that's just too
sweet a setup.

Incidentally, if he insists, I'd decline the job. Even if he signed
waiver after waiver to absolve you of responsibility (which I'd make him
sign), he could still go after you later when the consequences hit. Let
some less ethical coder do it the way he wants.

Sounds like you are not properly expiring the session.
The only login credentials that ever should be stored with the client is 
a session id.


Expire the session id - and the session ID in their cookie becomes 
completely meaningless.

I've done a bit of research into that, and can't find any evidence to
suggest that the so-called "friendly URL's" are actually of any benefit
to search engines. Just put a question into Google, and more often than
not, the top few results are from forums, which tend not to use these
friendly URL's. The only reason one might help with SEO is the case
where a site is being redeveloped or re-versioned, and you need to
preserve old page names to retain any ranking the site once had.

Of course, I'm welcome for any evidence to the contrary, so if any of
you have stumbled across links to any of that...
