I'm enjoying using the PHP class FPDF http://www.fpdf.org/ It's not a one-step conversion utility, it's a PHP class you invoke from your code to build the PDF document incrementally. If you've got a clear idea of how you want the query results rendered, FPDF can make it nearly as easy to output to PDF as to HTML.

[PHP] FTP - moving/copying files
I'm setting up an ftp manager which allows a user to connect to their space on an external server. All the php-ftp functions work fine - after I'd realized how to use the passive functionality - see previous email to list! I've also got working the download and upload functionality, which is quite nice, but annoying - it doesn't allow you to download the file without creating a temporary version (whereas if it were a local copy you'd be able to copy it to a variable, then echo it out... Finally, what I now need to do it be able to move/copy files within the FTP space. The standard FTP commands (mv cp or copy) are not featured in php-ftp functions. Does anyone have any suggestions bar copying the whole lot to a local drive then upload in the new space? Cheers Nunners

This still seems overly complex to me -- there are 3 identical occurrences of
some items.
When constructing an if() sequence, I think it's always important to isolate
the parts that genuinely differ, so my effort would go like this:
echo tr;
echo td$row[0] ;
if ($row[1] != none $row[1] != $row[2]) {
echo ($row[1]) ;
}
echo $row[2]/td;
echo /tr;

Whenever you need a elseif, then it's time to consider a switch -- like thus:

break;
case: $row[2];

[PHP] creating a threaded message system--sorting messages
This question might deviate from PHP into the domain of MySQL but I thought best to post here first. I'm building a message board system with PHP/MySQL. I'm trying to present the messages to the users in threaded order rather than flat. I'm having a lot of trouble figuring out how to sort the posts so they appear in the correct threaded order. I don't think I can do this purely with a SQL query. If it can be done this way, please suggest how and I'll take this question to the MySQL list. I think I have figured out the basic logic, I just have no idea how to translate it into code. Also, I may have the logic wrong. Anyhow this is what I have so far: relevant data structure loosely: post_id (unique, autoincrement, primary index) parent_id (if the post is a child, this field contains the post_id of its parent) ... 1) Query the database for all messages under a certain topic, sort by parent_id then post_id 2) Somehow resort the data so that each group of children is directly after their parent. Do this in order of ascending parent_id. Can this be done with usort() and some programatic logic/algorithm? How do you sort groups of items together rather than comparing each array element to the next array element (ie: sorting one item at a time)? Should this be done with a recursive algorithm? Anyone with experience writing code for this type of message board, or implementing existing code?

Re: [PHP] Update site through email
Hello, At my last job there were several companies that would send us text invoices by email. These email accounts were on a Linux box, and when the mail would come in the message was sent to scripts via STDIN. I'm not sure HOW it was done but I know that it CAN be done. I would be concerned about security in this case. The From: header can be spoofed, as can any other header, so before you do this make sure you have some kind of authentication scheme. Wouldn't want some lamer finding the email address and spamming it with v14gr4 email. -K.Bear Hy guys I'd like to know if there is a way to update a site through sending an email.

[PHP] Re: Update site through email
How i'd do it is not simple, i'm sure there is an easier method but here goes for mine. First you have to setup an inbox that you can read, it can be POP3 or IMAP, as long as your PHP script can read it it's fine. Second, create a script that can actually connect to that inbox and read for a new message periodically. You can use a CRONJOB or a Scheduled Task if it's available, else, you'll have to check the mailbox from time to time when your page launches from a web browser (Try not to do it all the time or your page will suffer from this process if it is launched all the time). That script will have to read the emails in the inbox, finds the appropriate email and stores the content the way you want, database or file, your choice. Then, your web page will have to read from that stored source of your choice and echo the content at it's right place. As you can see, it CAN be done, it's just a strange way of doing it. Furthermore i see problems to that. You can probably get very easily hacked using this method. Its easy to read the incoming data in the server, find the email address used to update the content and then send a mail yourself. There is nothing you can do to stop that except encrypt your email using SSL... But thats a bit hardcore and there are much simpler ways than using SSL encrypted email to update a page ;) Math Rodrigo de Oliveira Costa wrote: Hy guys I'd like to know if there is a way to update a site through sending an email.

I must admit, I've never used Pear for anything (I stick to SimpleXML
myself). Perhaps it doesn't like the new cdata tag you're writing? Have
you tried replacing the entire cdata tag with an empty string, or trying
another XML parser (like SimpleXML) just to see if the trouble is with
your XML or Pear?

[PHP] Re: creating a threaded message system--sorting messages
Ben Liu wrote: This question might deviate from PHP into the domain of MySQL but I thought best to post here first. I'm building a message board system with PHP/MySQL. I'm trying to present the messages to the users in threaded order rather than flat. I'm having a lot of trouble figuring out how to sort the posts so they appear in the correct threaded order. I don't think I can do this purely with a SQL query. If it can be done this way, please suggest how and I'll take this question to the MySQL list. I think I have figured out the basic logic, I just have no idea how to translate it into code. Also, I may have the logic wrong. Anyhow this is what I have so far: relevant data structure loosely: post_id (unique, autoincrement, primary index) parent_id (if the post is a child, this field contains the post_id of its parent) ... 1) Query the database for all messages under a certain topic, sort by parent_id then post_id 2) Somehow resort the data so that each group of children is directly after their parent. Do this in order of ascending parent_id. Can this be done with usort() and some programatic logic/algorithm? How do you sort groups of items together rather than comparing each array element to the next array element (ie: sorting one item at a time)? Should this be done with a recursive algorithm? Anyone with experience writing code for this type of message board, or implementing existing code? Thanks for any help in advance. - Ben Just throwing an idea out there, but you can do the sorting entirely in the SQL query. The trick is to figure out the best way. The first idea that came to mind (and it sucks, but it works), is a text field with padded numbers separated by dots, and the number is the position in relation to the parent. So, with this: Post 1 Post 3 Post 5 Post 6 Post 4 Post 7 Post 2 Post 8 Now, to the helper field would contain this for each post: Post 1: 1 Post 2: 2 Post 3: 1.1 Post 4: 1.2 Post 5: 1.1.1 Post 6: 1.1.2 Post 7: 1.2.1 Post 8: 2.1 Now, by pure ascii sorting in that field, that would sort out to: Post 1: 1 Post 3: 1.1 Post 5: 1.1.1 Post 6: 1.1.2 Post 4: 1.2 Post 7: 1.2.1 Post 2: 2 Post 8: 2.1 Which is the correct sort order. The depth of the post (how far to indent it?) could be told in PHP by counting the number of periods, or storing it in the database. Now, how to figure out what to put in that field for each post? We need to do two things. First, each post needs to store the number of children. Next, when a new post is made, we do three things (Keeping in mind that in real life I'd pad each entry in the sort helper field with zeros on the left up to some large number): 1) Get the sort helper field of the parent and the parent's child count field 2) Take the parent's sort help field, and add on a period and the parent's child count plus one, insert the child. 3) Update the parent's child count. OK, now, this method sucks. It's slow, and limits the number of child posts to whatever you pad (In itself, not a big issue, if each post can only have, say, a thousand direct childs (which each themselves can have a thousand childs), not a huge issue). The slow part from ascii sorting everything is the problem, I'd think. I've never done threaded anything before, so I assume there's a better solution. I'm just saying that the job CAN be done entirely with SQL sorting. And probably faster than your proposed method of resorting everything once PHP gets ahold of it.

[PHP] design?
Hi there, I am starting a new, very small project. A simple question and answering form. In one screen, question and answer can be typed, the strings will be saved in a database table questions which holds question and answer (as there is only one answer to a question). There will be a webpage displaying all the questions, clickable to the webpage of the answer to the question clicked. I want to create a class Question for dealing wiht the questions and a class answer for the answers. Each could contain an array with the their part of the content of the database table. The class Question manages the class Answer, so when instantiating the Question, the Answer will follow. Beside of this I want to create a 'visual' component class that creates the lists as displayed on the webpage. Is this a good idea? Or should I not bother, and just create one class Question that also deals with the Answers. Thanxs!

Re: [PHP] Re: creating a threaded message system--sorting messages
I've come into this discussion pretty late so please bear with me if I
go over something that has been ruled out.
You are trying to print out in a threaded method the first post in a
thread followed by each post after that, that is a child/reply to that
post. Is that correct?
So something like
Example 1
Thread1
Post1
Post2
Post3
Post4
.
or
Example 2
Thread1
Post1
Post2 - reply to post 1
Post3 - reply to post 2
Post4 - reply to post 1
Post5 - reply to post 1
Post6 - reply to post 2
Post7 - reply to post 3
Example 1 is very common and is the easiest to implement. From what I
remember you would need a couple of DB tables for post, post_thread,
post_post, thread
So for your question thread isnt very relative but I thought I would
throw it in.
thread {
threadid int(11) auto_increment,
threadname
threadsort
...
thread_post {
threadid int(11)
postid int(11)
post {
postid int(11) auto_increment,
postname
posttext
...
post_post
postid int(11),
postid2 int(11)
Please note I have two kids fighting over the cat, trying to cook
dinner and stave off a flood of water from the rising river so the SQL
structure is for example.
You can get everything in one query from the DB and lay it out based
on the id of the post, if you DB is properly indexed and setup and
queries are optimized you'll hardly notice a blip when the load gets
up. You do not want to be doing multiple queries on a page when one
well written query will do the trick.
Either way if this is more what you are looking for we can get into
specifics later.

Hello,
As Adam pointed out, this can be deadly to your database, especially as the
number of posts grows. If you want to go that route, I would recommend
selecting all the posts in that particular thread and sorting the data out
in PHP somehow. No need to slam your database with (potentially) hundreds of
queries to display a discussion. Multiply that by several page views at
once...
If you don't mind the extra work and investigation, I would recommend
downloading some PHP forum software that supports threaded discussion and
see how they implement it. I found several listed in DMOZ:
http://dmoz.org/Computers/Programming/Languages/PHP/Scripts/Forums/
Let us know what you come up with! I'd like to see how you work this out.
This is a good computer science type of problem with practical application -
the kind of stuff they should have taught me in school but never did. ~(o:
Best of luck,
-K.Bear
SOLVED, almost. I read the article suggested by K.Bear and found the
recommended solution to be a bit more complicated than I wanted to
implement. I then found another way to do this using the existing
Adjacency List Model through a recursive function. So basically, you
query the database for the post_id of the very first post in the
discussion. You then call a function that displays that post, searches
for all children of that post and then calls itself recursively on
each of the children it discovers. This works great for spitting out
the posts in the proper order. Now I'm trying to figure out how to
make sure the indenting looks right in the browser.
- Ben
Wouldn't that involve a separate SQL query for every post?

[PHP] xpath question
hi... in getting information on xpath/xml.. i thought i'd ask these lists as well... i'm trying to find out if there's a tool that i could use to load an HTML web page into, that would allow me to point to a given item/element within the Tree/DOM structure and allow me to see what the Xpath statement would be to generate that given itm/element of the Tree... i've seen a few tools but none that have exactly what i'm looking for... has anyone knowledge of any kind of tool/plugin like this? i'd also like to hear your comments pro/con of the tool if you've actually used it!! thanks -bruce -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] design?
Sjef wrote: Hi there, I am starting a new, very small project. A simple question and answering form. In one screen, question and answer can be typed, the strings will be saved in a database table questions which holds question and answer (as there is only one answer to a question). There will be a webpage displaying all the questions, clickable to the webpage of the answer to the question clicked. I want to create a class Question for dealing wiht the questions and a class answer for the answers. Each could contain an array with the their part of the content of the database table. The class Question manages the class Answer, so when instantiating the Question, the Answer will follow. Beside of this I want to create a 'visual' component class that creates the lists as displayed on the webpage. Is this a good idea? Or should I not bother, and just create one class Question that also deals with the Answers. You have essentially three pages: one that displays a form and inputs the entered data to a database; one that gets a list of questions from the database; one that displays a specific question/answer pair. As a ballpark estimate, I'd say that the above should be possible in under 100 lines of PHP code. You are looking at creating a Question class, an Answer class and a Visual/List class. The net result being that you double the number of PHP files and considerably increase the amount of code, there isn't much opportunity for code reuse here. Now, if the objective is to play with php OOP then go ahead. I would even suggest a DB class, a TableRow class, the Question and Answer then inherit from the TableRow, a TableRows class from which your List class would inherit. Maybe throw a few in to control the templates etc. as well. If the objective is just to get the job done and the site out, I don't see why you should bother with OOP at all.

Do this in order of ascending parent_id. Can this be done with usort() and some programatic logic/algorithm? How do you sort groups of items together rather than comparing each array element to the next array element (ie: sorting one item at a time)? Should this be done with a recursive algorithm? Anyone with experience writing code for this type of message board, or implementing existing code? Thanks for any help in advance. - Ben I've written such a system before more than once. You do the sorting in SQL, and then traverse the data recursively in PHP to build the tree. It's a single SQL query. Check the archives for this list for about 3-4 weeks ago, I think.

Re: [PHP] Functions
Two things:
1. You're not returning anything from the function.
2. You're not even using the function.

You need to return the value from the function:
return trim(strip_tags(.)
or pass in a reference:
