Re: [PHP] a question about user and permission on linux
There isn't a php user. If php scripts are executed through the web server, they belong to the server. If they are cli scripts, then they belong to the user that executed them, or the user the process that executed them is running as.

[PHP] PHP Question
Hello my name is Paulo Carvalho and I am struggling with the following: I am building a website with basic CMS functionality. My problem is that in one of the pages I am using Easyslider to display small comments about the clients. These comments are divided in 3 per slide. ex:(li pcomment 1/p pcomment 1/p pcomment 1/p /li) Now I am struggling with the following: I am pulling the comments from the db and I would like to know if i can split that array in 3's (array_slice) perhaps? My goal is to within a foreach loop output 3 comments within a slide(wrapped in li), so first 3 would output: (li pcomment 1/p pcomment 2/p pcomment 3/p /li) Then another 3 (li pcomment 4/p pcomment 5/p pcomment 6/p /li) Thank in advance for all the replies.

Hi everyone,
I hope you're doing well (haven't written here for a long time :-)).
The question is as follows: I have a regexp that would do the
following. If the string begins with Re:, it will change the
beginning to Re[2]:; if it doesn't, then it would add Re: at the
beginning. But (attention, here it is!) if the string starts with
something like Re[4]:, it should replace it by Re[5]:.
Here's the code:
$start=mb_strtolower(mb_substr($f['Subject'], 0, 3));
if ($start==re:) {
$subject=preg_replace(/^re:(.+?)$/usi, re[2]:$1, $f['Subject']);
} elseif ($start==re[) {
// Here $1+1 doesn't work, it returns Re[4+1]:!
$subject=preg_replace(/^re\[(\d+)\]:(.+?)$/usi, re[$1+1]:$2,
$f['Subject']);
} else {
$subject=Re: .$f['Subject'];
}
I know there actually exists a way to do the numeral addition
(Re[5]:, not Re[4+1]:).
How do I manage to do this?
This looks like a job for the e modifier (see
http://php.net/manual/en/reference.pcre.pattern.modifiers.php, and example #4
at http://php.net/preg_replace). Something like:
$subject = preg_replace(/^re\[(\d+)\:](.+?)$/eusi, 're['.(\\1+1).']:\\2',
$f['Subject']);

Watch out for the missing '[1]'. This needs to become '[2]' and not '[1]'.
The callback seems to be the only way I could get the regex to work.

Already provided an example using that : http://news.php.net/php.general/308728
It was the 'e' modifier I couldn't get to work, though I suppose, as
the code is eval'd, I should have been able to do it.
The callback just seems a LOT easier.

Regular expressions do not support any mathematical operations. Instead, you
need to use preg_match() to extract the number inside the brackets,
increment it, and build a new string using simple concatenation (.).
elseif ($start==re[) {
if (preg_match('/^re\[(\d+)\](.*)/i', $f['Subject'], $matches) 0)
{
$f['Subject'] = 'Re[' . ($matches[1] + 1) . ']' . $matches[2];

I cant see why you are getting the letter 'z' (assuming $msgContent was referenced properly) . Complete code will be helpful to debug the problem.

Not sure if it it is a typo above, are you actually passing
$msgContent in the function above? If it is a global variable, you
would need to add a 'global' declaration:
function ProcessForm($values)
{
global $msgContent;
mail('myemail:domain.com', 'Website Enquiry', $msgContent, From:
\{$values['name']}\ {$values['emailaddress']}\r\n);
.

Also try adding CRLF sequence at the end of the header line as shown above.

Re: [PHP] Array question
I'd also like to add to that:
$array = array();
$array[] = 'text';
$array[2] = 123;
$array[] = 'hello';
Would output:
$array(
0 = 'text',
2 = 123,
3 = 'hello',
);
Note the missing index 1, as php makes a numerical index that is one greater
than the highest already in use. As the index 2 was explicitly created, php
made the next one at 3.

Mike,
$results[] will automatically push a value unto the end of an array.
So doing this...
--
$magic = array();
$magic[] = 'a';
$magic[] = 'b';
$magic[] = 'c';
-
is exactly this same as doing this...
--
$normal = array();
$normal[0] = 'a';
$normal[1] = 'b';
$normal[2] = 'c';
-
And yes, in your example $results[] would be equivalent to $results[$j]

What PHP magic is at work here? Mike: That's just a shorthand way to populate an array in PHP. One of the reasons for this feature is that somewhere in your code you may not know what the next index should be. So, if you use -- $results[] = $next_item; -- then the $next_item will be automagically added to the next available index in the array. So you may be right in calling it PHP magic because I have not seen this in other languages. Understand?

What PHP magic is at work here?

Re: [PHP] PHP Email Question
Just on this topic, I found swiftmailer library to be really useful
esp. in dealing with 'template' emails with custom variables per
recipient:
http://swiftmailer.org/
The e.g. on email template processing:
http://swiftmailer.org/docs/decorator-plugin-howto
There are batchSend() functionalities, ability to compose various mime
type emails etc...

I would advise against ignoring the other parameters. Doing so will pretty
much guarantee having your email end up in SPAM. Instead look up the
examples in the docs, or better yet use something like phpmailer as Tom
suggested.

The mail command lets you send mail (an RFC2821 envelop). The function is:
bool mail ( string $to , string $subject , string $message [, string
$additional_headers [, string$additional_parameters ]] )
$to is where you want it to go
$subject is whatever you want the subject to be
$message is the information you want to send
Ignore the other parameters unless you are very familiar with RFCs 2821,
2822 and their associated RFCs
So if you want to send info from a form you might want to roll it up in xml
and send it via the message part. when you receive it you can easily decode
it. If you don't want to do that put it in a format that you can easily
decode on the receiving end.
Basically mail is a way to deliver information in the $message body. How
you format the information there is up to you. However, depending on your
system's config you are probably constrained to placing only 7bit ascii in
the $message body.
You might also move away from the mail function and look at phpmailer at
sf.net if you need more complex capabilities.

Re: [PHP] PHP Email Question
You should format the email message content first, like this:
$msgContent = Name: . $values['name'] .\n;
$msgContent .= Address: . $values['address'] .\n;
Then you should send a this content, like this:
mail('em...@address.com', 'Subject', $msgContent, From...);

[PHP] Image question for runways
Hi,
I am trying to create an on the fly image of runway layouts but am
hitting a brick wall.
I have both the starting and ending coordinates of each runway, it's
length, as well as it's angle of direction (heading).
I can draw one runway without any problem, but where I am falling short
is how to 'scale', if that is the right word, the other runway(s) to
display properly in a 500x500px image
function imagepolarline($image,$x1,$y1,$length,$angle,$color)
{
$length=($length/500)*20;
$x2 = $x1 + cos( deg2rad($angle-90)) * $length;
$y2 = $y1 + sin( deg2rad($angle-90)) * $length;
imageline($image, $x1,$y1,$x2,$y2, $color);
}
//'base' coords
$x1=200;$y1=200;
$scale=1;
//if first runway
if ($d==0) {$xbase=abs($lon1);$ybase=abs($lat1);}
//for all others
else
{
$x1=$x1+(($xbase-(abs($lon1)))*$scale);
$y1=$y1+(($ybase-(abs($lat1)))*$scale);
}
Here is some test data if that would help:
length,lat_start,lon_start,heading,lat_stop,lon_stop
6869,38.8424,-77.0368,355.5000,38.8612,-77.0387
4911,38.8423,-77.0408,26.,38.8544,-77.0333
5204,38.8617,-77.0438,142.7000,38.8503,-77.0327
Any suggestions would be most appreciated.

If I have time when you reply I'll answer the questions, but I must ask:
Is this purely academic? Why is this a concern? Have you encountered
issues? If so, what?
@Tom: I have compiled php with pcntl on and this has never been an
issue. It works well (on a linux setup), and I have deployed
standalone daemons with out any major problems. I have a home-grown
'preforker' framework (which I hope to share soon) which can be used
to exploit multi-core boxes.
@Shawn: It is not academic. There is a follow-up I am planning based
on the doubts above. I have deployed such daemons in the past with
some assumptions on (2) by doing manual cleanups - e.g. closing curl
connections, closing up db handles etc... Really want to understand
how php works in such setups outside of apache+mod_php.

could be listening to new requests via sockets etc..
Few questions:
1) Does opcode cache really matter in such cli-based daemons? As
'SomeClass' is instantiated at every loop, I am assuming it is only
compiled once as it has already been 'seen'.
I am not very clear on how apc (or eaccelerator) works in such cases.
2) What about garbage collection? In a standard apache-mod-php setup,
we rely on the end of a request-cycle to free up resources - close
file descriptiors, free up memory etc..
I am assuming in the aforesaid standalone daemon case, we would
have to do this manually? In the loop above, would it be better to
'unset($a)' explicitly at the end of it before
it goes to the next iteration?
Note: I have written pre-forker deamons in php directly and
successfully deployed them in the past, but never looked at in depth
to understand all the nuances. Anecdotally, I have
done 'unset()' at some critical places were large arrays were used,
and I think it helped. AFAIK, unlike Java, there is no 'garbage
collector' thread that does all the magic?
Thanks,
Ravi
If I have time when you reply I'll answer the questions, but I must ask:
Is this purely academic? Why is this a concern? Have you encountered
issues? If so, what?

[PHP] newbie question about code
I'm looking at someone's code to learn and I'm relatively new to programming. In the code I see commands like: $code-do_command(); I'm not really sure what that means. How would that look in procedural style programming? do_command($code); or something else? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It's object oriented code. $code is an instance of class, and do_command() is a method if that class. I'd advise reading up on oop php.

Not just Java, but does I've seen this in several languages.
Javascript is one. But realize that Java is to Javascript as Ham is
to Hamster. In other words, the two aren't related.

Re: [PHP] newbie question about code
Adam- It is unique. I'm writing code that really can't be done any other way. How it handles events, sockets, etc is exceptional. The best part is everything now is JavaScript. The server (Node.js) is written in JavaScript. MongoDB is JavaScript. The frontend used to manage the WebSocket is entirely JavaScript. I have essentially replaced J2EE as the backend with Node and I couldn't be happier. Of course standard JavaScript woes apply. Debugging is a royal pain in the ass. Your code can and will suddenly fail due to odd strange errors. There are stability concerns with Node, it is version 0.2 after all. It won't replace PHP or Java as an enterprise level solution, but it does fill in the gaps very nicely.

Excellent point about the debugging relative to other environments.

Hi, I've been using NetBeans for some time and I found that there are some issues like for Web applications if you write html tag incorrectlly, you wont be informed about that, for stand alone applications in Java there were also some stupid errors, etc. So, I strongly suggest to check out Eclipse(http://www.eclipse.org/)!

Re: [PHP] NetBeans Question
Hi there. I'm also a User of the Netbeans IDE and I can tell you the following: - Netbeans is the only IDE who can load very large PHP scripts (f.e. 1mb PHP Script with a multiple of 10thousands of lines) with syntax highlighting and SUPERB code completion. It works with include files, you can adjust RAM settings, you can work with files opened via ssh, Subersion integration is absolutley loveley, you can connect to a DB-Server with it to have the Schema and so on in your IDE, the Debugging feature works like a charm and it's simply much better than the following IDEs: - Zend Framework - Komodo Edit/ Komodo IDE - Eclipse - Kdevelop (heh - just kidding, mentioning this one) I Use it on Linux 64 bit and it simply rocks. @tedd: I'd just do what's obvious: Use a versioning system like Subversion. It can work via ssh, so there's no need to open a port for an extra daemon on any server. Further questions may be addresses to this list, I'd say. You'll have a more chances for an answer. ;) Regards 2010/5/31 Mario Lacunza mlacu...@gmail.com: Hello, what about the Netbeans ram eating?

Will the base IDE package be enough, or is there something specific it needs for PHP development, like a netbeans-php package? I'm using Linux (Fedora 11) btw ;) Thanks, Ash Ash: I'm really new at NetBeans and am having some minor questions I was keeping off-list -- however -- can go on list if there is interest. As for specific needs that NetBeans requires being an IDE for php, they make a special one just for php, see here: http://netbeans.org/downloads/index.html Find the one that fits your needs, like the one that covers only php and download it -- that's what I did. It's very easy to install and its learning curve is pretty easy. There are just some minor things that are not obvious, such as downloading a remote file to your local directory. You see, I use two different computers and have two accesses to the same server. Occasionally, I may change a file remotely and my second computer needs to be updated. I know this could be solved via some version scheme, but I don't want to make a big production out of it -- all I need to do is download a remote file, but I didn't see an easy way to do that. So, I searched for a couple of hours until I found someone said Simply, right-click on the file locally and choose 'download' and you'll overwrite the file -- that was simple enough. But I had to find out how to do it. These are the types of questions I have. I wanted to ask my questions on the NetBeans forums, but I am having trouble logging in. They seem to have a problem with my given ID, password, and email address and I haven't the time to straighten it all out -- I just want answers -- so I turned to this list.

Thanks very much, /Ernie You need some sort of content management system (CMS) for it. For something as simple as this it's not too difficult to build a basic app yourself, or you could use a pre-built system such as WordPress, Drupal, Joomla or PHPNuke. If you've already got the site built as a series of HTML pages, it might be worth converting those into .php files and then taking out all the common elements and put them into include files. That way, if you need to update the navigation bar, for example, you just need to edit the navbar include file once. I tend to store all the individual content for pages inside a database and then pull it out as I need it. This makes it easy to add in features such as a site search. I use the CKEditor rich text Javascript component to allow the user to format their content (I often limit the options available to them so they don't break stuff!) and give them basic options such as adding content and updating content like that.

[PHP] Malware Question
Hi all, This isn't exactly a PHP question, but I don't know anyone else with the collected smarts of this list. Basically, a site I built and am managing has been identified by Google as a source of malware. Now, I've been over the source code with a fine-toothed comb and found nothing, I've gone over the HTML output for anything suspicious, checked ever single Javascript file out, looked to see the server headers are correct and aren't malformed, checked the .htaccess is as expected and have run the site against the unmask parasites website which found no problems except the 'suspicious' listing which Google has given it. The Google webmaster tools tell me nothing more than 'Of the 2 pages we tested on the site over the past 90 days, 2 page(s) resulted in malicious software being downloaded and installed without user consent.' It won't tell me what pages, although it tells me that the malicious software is hosted on one domain and tells me what it is. Needless to say I can't find that domain string anywhere in the code. I can't find any hidden iframe tags or hidden Javascript eval() statements. Basically now, although this is totally beyond my control, the owner of the site is expecting me to get this sorted asap. I want to, and have spent the entire day today looking at it, but have really come to the point where I'm coming unstuck. I can find nothing wrong with the site at all. Does anyone have any helpful advice for this sort of thing? Tools that I can use to check out the site with, or any bit of information that I can use to fix this? I can give the URL of the site to anyone off-list if they wish to check it out. Thanks, Ash http://www.ashleysheridan.co.uk

Solution by Find factors of any number
1252398 is NOT a prime number: 1252398 = 2 * 3 * 7 * 29819
Work Shown
1252398 is divisible by 2: 1252398 = 626199 * 2.
626199 is divisible by 3: 626199 = 208733 * 3.
208733 is divisible by 7: 208733 = 29819 * 7.
29819 is not divisible by anything.
So 29819 by 42 (7*3*2)
would be a route.
Aha. Missed the 30 bit.
So, having found the factors, you would need to process them to find
the largest combination under 30.
2*3
2*3*7
2*7
3*7
are the possibilities (ignoring any number over 30).
Of which 3*7 is the largest.
So, 1,252,398 divided by 21 = 59,638
Is that the sort of thing you are looking for?
Yes, that looks exactly what like what I'm looking for. I'm going to try
and wake up the algebra side of my brain that hasn't been used in years
and
see if I can digest all this.
For the 2, 3, and 7, that is based solely on the last number being
divisible
by a prime number?

Thank you. It was a quick knock up, so could probably be optimized a

It will also not work beyond PHP_MAX_INT, unless the code is converted

// Change 17 to the max amount allowed in the last group

Solution by Find factors of any number
1252398 is NOT a prime number: 1252398 = 2 * 3 * 7 * 29819
Work Shown
1252398 is divisible by 2: 1252398 = 626199 * 2.
626199 is divisible by 3: 626199 = 208733 * 3.
208733 is divisible by 7: 208733 = 29819 * 7.
29819 is not divisible by anything.
So 29819 by 42 (7*3*2)

Aha. Missed the 30 bit.
So, having found the factors, you would need to process them to find
the largest combination under 30.
2*3
2*3*7
2*7
3*7
are the possibilities (ignoring any number over 30).
Of which 3*7 is the largest.
So, 1,252,398 divided by 21 = 59,638

I'm working on Windows, but I'm all ears for solution on Linux systems. Best Regards, Bastien The easiest thing is to set up a local web server on your machine to test with. This isn't as daunting as it sounds, as there are a lot of ways you can get this set up with a minimum of fuss. The easiest to use software I've used for Windows was EasyPHP, which is basically a WAMP stack that is GUI all the way, allows easy add/drop of extra modules, and now ever comes with an English installer (it used to be all in French which made it a little tricky to understand!) Otherwise, if you want to try the Linux route you can set this up on a second machine, dual-boot with Windows or run inside a virtual machine (Virtual Machine OSE is open source and free to use). I've not seen a Linux distribution yet that didn't offer Apache and PHP. Generally a web server will run something like Fedora, RedHat or CentOS, so using one of those will get you a very similar set-up. Thanks, Ash http://www.ashleysheridan.co.uk

Best Regards, Bastien A couple of IDEs have web servers built in (NuSphere PhpED is the only one I can remember at the moment) which can generally be used to preview your applications offline, although you might struggle to get it running if it requires a database connection, depending on your hosting config (my hosting will only allow local connections to the DB). Alternatively, something like EasyPHP http://www.easyphp.org/ makes it very easy to get a LAMP server set-up going on your machine, so you could drop your app into the www folder and navigate to localhost on your web browser to view it. Stick some dummy data in the db and you have a fully functional version of your app running on your machine.

Hey all!
This is probably my second post on the list, so please be gentle. Right
now
I am running through the Heads First PHP and MySQL book from O'Reilly.
It's been quite enjoyable so far, but I have some questions about some of
the code they're using in one of the chapters.
Basically the code is retreiving rows from a DB, and I'm just not getting
the explanation of how it works.
Here's the code:
$result=mysqli_query($dbc,$query)
while($row=mysqli_fetch_array($result)){
echo $row['first_name'].' '.$row['last_name'].' : '. $row['email'] . 'br
/';
}
Now, I know what it does, but I don't understand how the conditional
statement in the while loop works. Isn't an assignment operation always
going to result in a true condition? Even if
mysqli_fetch_array($result)
returned empty values (or null) wouldn't the actual assignment to $row
still
be considered a true statement? I would have sworn that assignment
operations ALWAYS equated to true if used in conditional operations.
Please help explain! :)
Thanks so much!
-Matty
http://www.php.net/manual/en/function.mysql-fetch-array.php
Returns an array of strings that corresponds to the fetched row, or
FALSE if there are no more rows.
while($row=mysqli_fetch_array($result)) is equivalent to this:
$row=mysqli_fetch_array($result);
while ($row){
// do something
$row=mysqli_fetch_array($result);
}
So, if $row is not equal to FALSE, the loop will happens.
Another part to the answer is the value of the assignment. From the
documentation (http://docs.php.net/manual/en/language.operators.assignment.php),
...
The value of an assignment expression is the value assigned.
while($row = mysqli_fetch_array($result))
But there is a significant issue here. Whilst not attributable to the
mysqli_fetch_array() function, it is certainly possible to give
yourself a significant WTF moment with it.
May be will be easier to see the problem when the code is written as ...
while(False === ($row = mysqli_fetch_array($result)))
No?
If I say ...
0 == False
does that help?
Without running the 2 stupid scripts below, what output should you get?
?php while($pos = strpos('abc', 'a')) { echo 'a';} ?
and
?php while($pos = strpos('abc', 'z')) { echo 'z';} ?
Clearly, they should be different, yes?
Unfortunately, they won't be.
The first call returns 0 and the second returns False.
And as 0 == False, the while() does not loop.
But ...
?php while(False !== ($pos = strpos('abc', 'a'))) { echo 'a';} ?
and
?php while(False !== ($pos = strpos('abc', 'z'))) { echo 'z';} ?
now operate correctly. The first one runs forever, printing a's and
the second one quits straight away.
By always using ...
while(False !== ($var = function($param)))
you can clearly differentiate between functions that return false to
indicate failure and 0 to indicate a position or actual value.

Richard.

Re: [PHP] Newbie Question about Conditionals
After looking up the === operator, I see exactly what you mean. Thanks for
your help everyone. I think the confusion was that I was always under the
impression that assignment is either true or false; I would never have
guessed it was equal to the value assigned. Your examples really helped to
solidify the concept though!
PS: I have to say that PHP has the *best* documentation I've ever seen
beside Java.
