[PHP] Re: [PHP-INSTALL] Getting file pointer from file descriptor
You seem to be quite confused. First of all, a function like fdopen() which has never existed in any version of PHP, wouldn't read/write anything. In C that function will return a FILE pointer from a file descriptor. You would then use fread()/fwrite() to read and write from that FILE pointer. But PHP doesn't have file pointers nor file descriptors, so none of this applies to PHP. In PHP an open file is a resource just like an open database connection is a resource. So, is your question really how to read and write to files? There are many ways to do that. The easiest is to just call file_get_contents()/file_put_contents(), but you can also use fopen()/fread()/fwrite() if you prefer that approach. -Rasmus On Fri, Apr 16, 2010 at 5:15 AM, Naga Kiran K k.nagaki...@gmail.com wrote: Hi Rasmus, Thanks for reply. The requirement I was looking for is to read/write given only the file descriptor number. PHP-CGI binary is invoked by a webserver that runs in jail-directory and doesn't have access to the file path directory. So, it communicates with another daemon that opens a socket to that file and in turn passes the file descriptor alone. Can you please suggest if there is any API in PHP that serves this requirement [read/write to given file descriptor] Please let me know if I need to provide more information.

[PHP] escape \n
Hello guys i am trying to figure out what is worng with thoose special escaped character, like \n \t \r ... As i cannot make them working. The browser doesn't display them, but doesn't eithr crate a new line, or else. I am using them fro example like this: print: this shoudl be on a line \nwhile this on a new line; I've searched google and saw man people struggling with this, but apparently not a clear answer to whymaybe is a stupid beginner question, but i would just like to know. (Personally i solved for the moment by printing out br or pre, but i would like to understand this. Cheers, Nick

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?
Joao, Jason, thanks for the code.

[PHP] public readonly variables
I know the subject line might sound a bit like an oxymoron, but bear with me! What I'd like to have is a property of an object that behaves like a public variable when it comes to reading, but like a protected one when it comes to writing, as it would make my code a lot easier to read. I know about the __get($var) method to magically provide this behaviour, but from all I've read it can be pretty slow compared to a regular public variable. I've seen a thread on the dev lists where someone requested it, but can't find anything in the manual. Does anyone know if this is available in a later version of PHP, or if it's implementation is penned for some time in the future? Thanks, Ash http://www.ashleysheridan.co.uk

I started the way I guess most people did: from a basic book which broke things up as it saw best. Obviously some books are better than others; I won't mention any here as there are quite a few threads about good PHP books. From there, I just looked into what I thought I needed to know as I came across it. It's a bit haphazard, but it did the trick. Mostly though, I think if you find a good book, that should break things down well enough that anyone can pick it up and follow along. You don't have to follow a book linearly though, I found myself often focusing in more depth into something a book only mentioned briefly because it either sounded interesting or I needed to know more for a project.

[PHP] htmlentitites ENT_QUOTES in HTML attributes?
Hi List,
I just figured, that the Browsers on my system do interpret #039;
inside href or onclick attribute as a plain '.
Imagine the user input is the following line:
param2 foo';);alert(document.cookie);alert('
Which is being written by the script like that:
a href=javascript:void(0); onclick=test(1,
'USER_INPUT_GOES_HERE');test/a
USER_INPUT is sent through htmlentities($str, ENT_QUOTES, 'UTF-8');
The result is the following then:
htmlbody
script type=text/javascript
function example(a, b) {
alert('valid alert; params: '+ a+', '+b);
}
/script
a href=javascript:void(0); onclick=example(1, 'param2quot;
foo#039;);alert(document.cookie);alert(#039;');test/a
/body/html
My browsers will alert the document.cookie.
Please confirm this (and keep in mind that document.cookie is just
empty when tested locally).

It's easier if you already know how to code in a different language; then you really mostly need to know the differences between the languages. If you want to learn without the benefit of a book, then I'd suggest looking over existing beginning programming books for various languages. My observation is that they generally follow a pattern.

I'm sorry for the delay in response, I was able to create the child table,
which works great.
So thank you to everyone that responded Helped.

[PHP] creating a PHP wrapper script?
i'm sure this isn't hard to do, but i'm having end-of-week brain cramps. just now, i installed a PHP package that lets me download thumbnails of image files stored on a server -- the URL to generate and download a thumbnail is, say: http://server/d1/d2/thumbnail.php?fileID=whateverarg1=val1arg2=val2 and so on. unsurprisingly, the thumbnail generation program accepts numerous arguments and is incredibly sophisticated, and is stored in a subdirectory under /var/www/html and ... well, you get the idea, calling it directly involves creating quite the URL. instead, i'd like to stuff a wrapper script at the top of the document root which hides all that complexity, so i can just browse to: http://server/thumb.php?fileID=whatever and have that top-level thumb.php script make the appropriate invocation to the real thumbnail.php script with all of those (default) arguments and values. so, what would thumb.php look like? i obviously need to simulate a POST call, retrieve the output and pass it back unchanged. thoughts? surely this is something that people want to do on a regular basis, no? rday -- Robert P.

Whilst you can easily code __get()/__set() or getVar()/setVar()

[PHP] Remote Key Question
Hi gang: A few times I've found myself confronted with a problem that might be better solved than the way I currently solve it. I would like your opinions/solutions as to how you might solve this. Here's the given (as an article/author example). I want to create a list of articles in a database. The articles are listed in a table with the fields title, description, and author. article table: id - title - description - author The authors are listed in a table with the fields name and bio. author table: id - name - bio Now here's the problem each articles will have one, but perhaps more authors -- so how do I record the authors in the article table? As it is now, I use the remote key for each author and separate each key by a comma in the author field of the article table. For example: author table: id - name - bio 1 - tedd - tedd's bio 2 - Rob - Rob's bio 3 - Daniel - Daniel's bio article table: id - title - description - author 1 - PHP Beginner - Beginner Topics - 1 2 - PHP Intermediate - Intermediate Topics - 1,2 3 - PHP Advanced - Advanced Topics - 1,2,3 As such, article with id=3 has a title of PHP Advanced and a description of Advanced Topics with tedd, Rob, and Daniel as authors. Is there a better way to link multiple authors to an article rather than placing the remote keys in one field and separating them with commas?

I think for now I'll just resort to leaving it as a public variable.
I'll leave the specific set function for it in and just hope that is
used instead! As it's only me who'll be using it for the time being, I

A third table does have the added advantage that you might specify the type of author they were.

The setter is to go some way towards keeping the values sane, which I realise goes against the whole public variable thing, which is the reason for my original question. Another reason for the setter is that it actually modifies a couple of variables, so there's no good way of getting rid of that, as it would then mean setting two properties of the object manually, which would actually lead to more issues down the line if not set correctly.

If not, or if an author may belong to more than one article (many to many) then a third table is the way to go, and use a couple of joins. A third table does have the added advantage that you might specify the type of author they were. For example: idauthor_idarticle_idtype(enum maybe?) 1 11 main 2 21 co 3 12 main The third table is obviously more complex, but offers a better relationship model to be built between authors and articles.

If its just for listing authors of an article, not letting them edit it, the my solution is best but if it was was editing I would go with Ash's approach maybe even making is so its something like ArticleParts: ID|ORDER|ArticleID|UserID|ENUM(OWNER,CONTRIBUTOR) So that the owner can edit any ArticlePart in their article but the CONTRIBUTOR can only edit their specific part.

Adam -- Nephtali: PHP web framework that functions beautifully http://nephtaliproject.com There is a trend towards denormalization (see BigTable, SimpleDB, etc), and generally, I'm an advocate of the phrase Normalize until it hurts, denormalize until it works. However, part of the question is how does Tedd want to be able to query the data. If it's possible that he wants to query from the authors table to the articles table (e.g., select all of the articles that Richard wrote), a junction table gets much more useful (and easy relative to the denormalized approach), especially as the queries increase in complexity. So, Tedd, I'd carefully evaluate your expected query needs, and if they're basic, your current scheme would work, but I suspect a junction table would be better in this particular case.
