[PHP] [JS question] : I want to block onChange event in Firefox...

2006-06-30 Thread David BERCOT

Hi,

I am blocked on this problem since so a long time that I prefer asking here my 
question...
I'd like, if the data isn't correct, that the user stay in the input zone. 
Everything is ok with IE but not with Firefox.
Here is my code :
// Validation des données.
function demarrage_controles() {
  if (FF) {
document.captureEvents(Event.KEYPRESS);
document.captureEvents(Event.CHANGE);
document.onkeypress = process_keypress;
document.onchange = process_change;
} else {
document.onkeypress = process_keypress;
for (i=0; i < document.forms[0].elements.length ; i++) {
  
document.forms[0].elements[i].attachEvent("onchange",process_change);
}
  }
}
// On n'accepte que des chiffres.
function process_keypress(e) {
  if (FF) {
if (e.target.tagName == "input" && !((e.which > 47 && e.which < 58) 
|| e.which == 0 || e.which == 8 || e.which == 13)) {
  return false;
}
  } else {
if ((window.event.keyCode < 47 || window.event.keyCode > 58) && 
window.event.keyCode != 13) {
  return false;
}
  }
}
// On compare au dernier cumul.
function process_change(e) {
  if (FF) {
if (e.target.id.substr(0,3) == "var" && e.target.alt != "") {
  if (Number(e.target.value) < Number(e.target.alt)) {
alert ("Vous ne pouvez pas saisir de données 
inférieures au dernier cumul !");
e.preventDefault();
e.stopPropagation();
e.returnValue=false;
  }
}
  } else {
if (window.event.srcElement.id.substr(0,3) == "var" && 
window.event.srcElement.alt != "") {
  if (Number(window.event.srcElement.value) < 
Number(window.event.srcElement.alt)) {
alert ("Vous ne pouvez pas saisir de données 
inférieures au dernier cumul !");
window.event.returnValue = false;
  }
}
  }
}
My problem comes from the process_change function in Firefox where I put 
everything I know (stopPropagation etc...) but without success. The user go to 
the next field. In IE, the window.event.returnValue = false is ok.

Do you have any clue ?

Thank you very much.

David.

[PHP] Stop process when user close window browser

2006-06-30 Thread weetat


Hi all,

 I am using PHP 4.3.2 and MYSQL database.
 I think this question has been asked many times, however not solutions.

 The problem is that I have a php script which connect to db and update 
data to db which took length of time to be completed. However sometimes 
user accidentally close the window browser or kill the window browser.
The php which a server script language will not know that the window 
browser has been closed , so the program execution is keep running .

This will choke the memory in the server and thus choke the web page.

So ,are there ways to stop program from executing when user close the 
browser window.


Thanks

By default, PHP will also stop execution when the browser is closed. See:

Yes I did. No error...

I was told to go to a JS list (here, it is a PHP one), so I'll look for one ;-)

[PHP] bug in php 5.1.4

2006-06-30 Thread Alain Roger


Hi,

I' ve discovered a bug in PHP 5.1.4. This version of PHP create a new
session everytime you refresh the same php page or that you switch from 1
page to another page.
I downgraded it to PHP 5.1.2 and it works correctly.
It could be interesting to fix this bug.

if you want moredetail, contact me.

There must be a special code in your script that causes it like this bug:

if it is a bug it sounds like it's rather critical!

you might want to post a small repro script to internals to illustrate the
problem... if you do you better off asking if it is a bug rather than declaring
it to be so.

chances are that you'll be asked to make a report at bugs.php.net if someone 
sees
merit in your observation.

Hi all...
I'm interesting in a page (using PHP script) in internet,

the question is:
Can I..?
  

Hi,
you can't directly.
you have to ask the webmaster of the site.
but the source code won't be helpfull if the script requires other

PHP doesn't know the browser has gone away until it tries to write 
something to it.  So if you are inside a long-running SQL-query and the 
browser drops, nothing will happen until the query call returns and you 
try to write something.

Hi Larry,

Thanks for the help. I was just coming to a similar conclusion last  
night after reading the warnings on this thread about querying the  
database recursively. I guess my test data with 7 posts is not a  
rigorous simulation. :-)


I've looked through the posts on the PHP general list going back  
about 3-6 weeks and can't find the thread you speak of. I searched by  
your name assuming that you posted into the thread and searched by  
the string "recursive" and "recursion". If you could steer me to it  
in some other way (subject of the thread or subject word) I would  
appreciate it, but only if it is not too much trouble. I can take a  
go at it now that the basic approach is carved out: query once,  
recurse the data in PHP.


Thanks,

the 'right' that he has to see them (or others have to see his cookies)
has nothing to do with whether it is technically possible.

the HTTP specifications state that a site should only have access to
cookies set within it's own domain - so in a perfect world Peter doesn't have
access.

BUT:

1. security flaws in browsers (and/or webservers?) can (and have) occassionally
make cookies available to third parties unintentionally.

2. cross-site-scripting (XSS) hacking techniques are capable of stealing
cookie data from third parties.

you can't do much about 1. but you can take measures to protect your site
from XSS. http://www.phpsec.org is a great place to learn more about XSS and
other security issues.

> Asking such unethical

there are no unethical questions and to presume that Peter is out to steal
other peoples cookies is shortsighted - there is no evidence to back this up...
turn it around - maybe he wanted to know if it was possible for other 
people/sites
to view *his* cookies.

the ethical issue arises if Peter would try to read cookies that don't belong to
him/his site.

I feel it was unfair to insinuate dumbness; if you want to call people dumb why

Point well taken -- but how about placing one link to the "best" reference? We

At least we can say "Did you read the intro?" or "Please read the intro." when

Hi there,


Hi Sjef,

First off, I think David has a good point with regards to the OO vs
Procedural approach.  If you're looking to do this quick and easy, it
might not be worth your time fussing with OO.  Unless you'd like to
just for the exercise, which I wholly support, so go for it!


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.


As far as how to design it OO-style, I'd first urge you *not* to have
separate classes managing lists of questions and answers.  Say for
example you query your db for questions, build up your array inside
your questions class, and then while doing the same for your answers
class, you inadvertently introduce a looping bug that drops one of the
answers from the array, or possibly changes the order that you create
your array, or any other number of possible mistakes (human or
otherwise).

Point is, in the end you'd have two out-of-synch classes that really
should've been built separately to begin with.  A single question and
it's answer(s) are tied together, so keep it that way in your class
abstraction.

That said, I'd suggest building a question-answer *pair* as a class,
and then you'd have an array of these question-answer pairs
representing your entire list (which could be encapsulated into a
container class if you wished).

You could, to be even more abstract, create base question and answer
classes to represent the most basic type of question or answer, and
then hold individual, **related** instances of these within your
question-answer pair class.  Do you see the difference?

You could even take it a step further and build derivatives of your
base answer class to represent different types (string, multiple
choice with one answer, multiple choice with many answers, etc)...But
I'm sure I'm already getting far ahead of your original design.  But
David started it!  :)

Yep, you're on the right track here.  If your tree is a directed acyclic
 graph (read: every node has at most one parent, and never loops back on
 itself), then it's quite easy to do with one SQL table and one SQL query. 
 (Or similar, if you're not using SQL, but I've done this many times in SQL.)

First, fetch a list of all nodes, in whatever sort order you want (say,
alphabetical), ignoring the nesting.  You want an array of records (an SQL
result works, or an array of objects, or an array of arrays), where each
record has at minimum its own ID and its parent ID (0 meaning it's a root
node), and some sort of label.

Then, starting at parentid=0, iterate over the list and process just those
with that parent id.  "Process" means, in this case, for example, to print
out a list item with the name, save the current cursor, and call the function
again recursively with the id of the active node as the new parent node.
When you return, reset the cursor.  The cursor stuff is so that you can pass
the array by reference rather than by value and not waste a ton of memory.

So the pseudo-code would look something like:

function foo(&$nodes, $parentid) {
  reset($nodes);
  foreach ($nodes as $node) {
if ($node's parent is $parent id) {
  $output .= ""
. $node (or whatever portion of it you want)
. foo($nodes, $node's id)
. "";
}
  }
  if ($output) return "$output";
}

$nodes = get_my_nodes();
$list = foo($nodes, 0);

There's probably a small bug in the above somewhere since I haven't tested
 it, and it would vary a bit if you're operating on an SQL result directly,
 but that's the basic idea.  The advantage is that you get HTML that is
structurally representative of the relationship, as well as pre-styled for
you by default by any browser.

Not true.  I've come to really appreciate the structure of switches.
What helps to "unlock" their power is that you don't *have* to compare
your switch() param with your case() params.

Building on Paul's good advice of splitting logic from presentation:

[code]

$display_name = '';

switch('set_display_name')
{
case($row[1] == 'none'):
case($row[1] == $row[2]):
$display_name = $row[0] . ' ' . $row[2];
break;

default:
$display_name = $row[0] . ' (' . $row[1] . ') ' . $row[2];
break;

}

// now print table, using $display_name
[/code]

[PHP] apc and ZendPlatform

2006-06-30 Thread Rick Emery

We're running Zend Platform on a server that also has apc installed;  
we're using apc in the scripts to cache data, and I understand (I  
think) that it also does bytecode caching.


Zend Platform includes a php accelerator, which (I think) is also  
caching bytecode.


Does anybody know if we'll see adverse effects from this?

apc comes with a cool page (apc.php) that shows information about its  
cache. While it shows that scripts are being cached, it's showing 0  
hits for all of them. That seems wrong to me, but I may be  
mis-understanding it.


Does anybody have any insight?

Thanks in advance,
Rick

Re: [PHP] Stop process when user close window browser

2006-06-30 Thread tg-php

On the other hand, you can tell the web server that the browser has been closed 
or the page has 'exited'.  Not 100% reliable, but in theory you could use the 
"onUnload" (think that was it) event for a web page   that does something sloppy like spawn a popup 
window that hits a PHP script that then checks MySQL processes or something.

Not a great solution, but if you really need some kind of feedback to the 
server if someone leaves a page, that may be one way to do it.

Also, another thing to think about, don't confuse an active query and an active 
database connection.   What you may be seeing is just the database connection 
still active.  You can use the database query "show processlist" to see if the 
connection is just open or there's actually a query still running.

PHP doesn't know the browser has gone away until it tries to write 
something to it.  So if you are inside a long-running SQL-query and the 
browser drops, nothing will happen until the query call returns and you 
try to write something.

only if you turn on both accelerators (opcode caches) - at least trying
to run both is more than likely to open up a whole can of worms and leave your

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.

Dan McCullough wrote:

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


Not a valid example, because there is no guaruntee that the posts are in 
order. In your example, the order could easily be:


Thread 1
 Post 1
  Post 6
   Post 7
 Post 2
 Post 3
  Post 4
   Post 5

Since somebody can reply to any leaf in the tree at any time.




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)



Tables that serve only to tie two other tables together are a waste. I 
suggest you look up your normal forms again. But to sum up the 
reasoning, there is no point to have thread_post because you can simply 
have a "threadid" field in the "post" table, because it's a one-to-many 
relationship. A post can't belong to more than one thread.




post {
postid int(11) auto_increment,
postname
posttext
...

post_post
postid int(11),
postid2 int(11)



Same thing,  I think. A post can't have more than one parent, so you 
might as well put the parent id into the post table. Unless you have one 
"post_post" row for every parent that a post has. This spams the 
database like nobody's business, but makes queries easier.




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.


I'm not seeing it. Unless you have a many to many relationship on 
post_post, you're going to need multiple queries. Unless I'm missing 
some SQL syntax that allows references to previously found rows. It's 
been a long while since I did advanced SQL queries.


I think your example relies on getting everything in one query by 
getting all posts with the same threadid, and then sorting by ID, but 
the problem is that we don't want to sort posts by ID, since a higher ID 
might could easily go before a post with a lower ID based on where 
people replied.

Re: Re: [PHP] Re: creating a threaded message system--sorting messages

2006-06-30 Thread Ben Liu


Thanks to everybody who posted on this thread. I wanted to post back
the solution I came up with after removing the DB query from the
recursion. In case anyone else is trying to accomplish the same thing,
this is how I solved it (criticisms welcome, and note that I have not
tested it extensively yet):

DB structure

table: discussion_posts

post_id (auto increment, unique, primary index)
parent_id (post_id corresponding to this post's parent)
discussion_id (to allow multiple discussions, not required but I added
a discussions
member_id (to identify the post to the particular member posting the post)
table as well to store the discussion description and unique ID for
each discussion)
dt_posted (date/time the post was posted)
subject (title of the particular post)
post_text (substance of the post)

So the user selects a particular discussion from a list of
discussions. We query the database for the post_id of the first post
in the discussion requested, this post will have a parent_id of '0' or
NULL since it has no parent. We then query the DB for all the posts in
the discussion joining the members table using member_id to grab the
member's first and last name (or any other member info desired). We
order this query info by dt_posted.

We then write the contents of our second query into a two-dimensional
array ($workArr):

while ([EMAIL PROTECTED]($result)) {
 foreach ($row as $key => $value) {
   if ($key=="post_id") $numerKey=value;
   $workArr[$key][$numerKey]=$value;
 }
}

The processing of the threads into proper order looks like this:

function processthread($post_id, $workArr) {
echo "";
echo "{$workArr['subject'][$post_id]} (#{$post_id})\n";
echo "by {$workArr['first_name'][$post_id]}
{$workArr['last_name'][$post_id]} "."• on " .
fixdate($workArr['dt_posted'][$post_id]) . "";
echo "{$workArr['post_text'][$post_id]}\n";
echo "reply to this";
// find all children, call itself on those too
foreach ($workArr['post_id'] as $value) {
if ($workArr['parent_id'][$value]==$post_id) {
processthread($workArr['post_id'][$value], $workArr);
} // end if
} // foreach
echo "";
}

And somewhere in the HTML, where appropriate, the function
processthread is called for the first time passing it the $post_id
value we determined in the first query (the very first post of the
discussion) and the $workArr array.

Use of unordered lists for design/layout is helpful here since
browsers will by default indent lists within lists and list items
within their respective list. This saves some PHP and CSS troubles if
one were to use  or  structure instead, as I found out.

Apologies for any formatting issues and vagaries about the data
structure and variable naming in this post.

How about this -- a paraphrase of which occurs in many of my scripts:

   if (isset($_POST['id'])):
  $id = $_POST['id'];
  // etc. -- other initializations based on $id
   elseif ($_POST['action']=='add'):
  $id = generate_id();
  // initialize stuff to empty values
   elseif (potential_other_test_to_detect_other_valid_states()):
  // other stuff
   else:
  KaBlooie();
   endif;

Of course, that *could* still be implemented using the switch(TRUE) technique 
(and I've used that elsewhere), but in a case like this instance I prefer the 
if/elseif construct.

Cheers!

Re: [PHP] design?

2006-06-30 Thread Sjef

Thanks, John,
I'm not sure I completely get the idea of a pair class.

As an question and answer are in the same database tabel I now created a 
questionDepot class that gets the array from the db, does save and update 
operations, and for example, sets a flag in the db tabel when a question is 
accepted for the list.

My question was asked with the experience that a complete procedural 
approach often turns out to become messy, you have to use certain visual 
objects more often in teh app, therefore why not create a visual class to 
use more than once.

So, it was just an urge to write cleaner code 

By the way: as always, I already exceded the 3 or 4 pages David mentioned, 
if only for the idea to add a 'placed' tag in the db.

A more descriptive explanation along with some code will help us to help
you. AFAICS we do not have enough information to go on. Does each frame
generate its own session? Can you show us that? The last session setter
always wins if the variables are the same. So, if I say;

$_SESSION['user'] = 'foo';
$_SESSION['user'] = 'bar';

echo $_SESSION['user'];

Like any good variable will return its last given value;

2. Optimize opcode
3. Cache opcode

I need to be able to cache data. If I set apc.cache_by_default to off,  
can I still cache data within the application using apc_store and

Yes. If you are using mysql, why not create  connection functions that sit

Sorry, here's more information:

I have a remote session system, like a database or a cache.
I have an Apache server running PHP 5 (although it does it on 4.x as well)
I am running Squirrelmail on the server.
Squirrelmail has frames.
The frames on squirrelmail each use the same session information
Multiple frame requests are sent from the browser at the same time.
The time to handle the requests is a non-zero amount of time that varies
with each frame
session_start is called for each frame request
The frame pages are processed
The session information saved via (I believe) session_write_close for the
frame requests
as each frames modifications to the session data is saved, the last session
to finish ends up writing the final version of the session data.

A log looks like this:

PS_READ_FUNC()
PS_READ_FUNC()
PS_WRITE_FUNC()
PS_WRITE_FUNC()

It should look like this:

PS_READ_FUNC()
PS_WRITE_FUNC()
PS_READ_FUNC()
PS_WRITE_FUNC()

In my session handler code, I have added a loop that looks like this:

for(tstart=time(0); elapsed < 30; elapsed = time(0) - tstart)
{
stat = network_lock(xkey);
if(stat==LOCK_OK)
{
NETLOCK_G(fdlock) = xkey;
break;
}
sleep(1); // Connection is busy, sleep for a second
}

This fixes the problem, but requires that PHP poll. I can put the same login
the the network system, but then that requires a socket and perhaps a
thread.

Does PHP have a way to tell the browser to respond once frame at a time, or
some more efficient serialization methodology.

You need to return the value from the function:

return trim(strip_tags(.)

or pass in a reference:

function cleaner (&$var)

One wild theory would be that the Zend Cache has been holding your
entire set of PHP scripts in RAM, so has never had to hit the "disk"
for the source, and so APC, down in the chain later, has never had
anybody even ASK for a page a second time...

Using both Zend Cache and APC together seems decidedly "odd" to me,
but there it is...

Instead of trying to stop it, just "Don't Do That"

Whatever it is you need the database to do, set something up to let it
do that task "later" while the user isn't stuck waiting for your

[PHP] Quick Question re: Windows/Linux PHP

2006-06-30 Thread Beauford

Hi,

I'm just curious, because I come across this from time to time.

Why does the code below work on Windows and not on Linux. PHP is 5.0 on
Linux and 4.4 on Windows (still can't get 5 on Windows). The code at the
very bottom is how I got it to work on Linux. Also, why is it with the same
setup I can't call a function within a function in Linux, but can in
Windows. Sorry I don't have the error, but something about calling a static
function. Would this be a difference between OS's or with the different
versions of PHP? 

Thanks

If you have physical access to it, Netscape and IE cache their
non-session cookies in files you can dig out.  Session cookies can be

If you mean to ask if you can see from your server, the cookies I sent

Re: [PHP] Re: creating a threaded message system--sorting messages

2006-06-30 Thread Adam Zey


Ben Liu wrote:

Thanks to everybody who posted on this thread. I wanted to post back
the solution I came up with after removing the DB query from the
recursion. In case anyone else is trying to accomplish the same thing,
this is how I solved it (criticisms welcome, and note that I have not
tested it extensively yet):

DB structure

table: discussion_posts

post_id (auto increment, unique, primary index)
parent_id (post_id corresponding to this post's parent)
discussion_id (to allow multiple discussions, not required but I added
a discussions
member_id (to identify the post to the particular member posting the post)
table as well to store the discussion description and unique ID for
each discussion)
dt_posted (date/time the post was posted)
subject (title of the particular post)
post_text (substance of the post)

So the user selects a particular discussion from a list of
discussions. We query the database for the post_id of the first post
in the discussion requested, this post will have a parent_id of '0' or
NULL since it has no parent. We then query the DB for all the posts in
the discussion joining the members table using member_id to grab the
member's first and last name (or any other member info desired). We
order this query info by dt_posted.

We then write the contents of our second query into a two-dimensional
array ($workArr):

while ([EMAIL PROTECTED]($result)) {
 foreach ($row as $key => $value) {
   if ($key=="post_id") $numerKey=value;
   $workArr[$key][$numerKey]=$value;
 }
}

The processing of the threads into proper order looks like this:

function processthread($post_id, $workArr) {
echo "";
echo "{$workArr['subject'][$post_id]} (#{$post_id})\n";
echo "by {$workArr['first_name'][$post_id]}
{$workArr['last_name'][$post_id]} "."• on " .
fixdate($workArr['dt_posted'][$post_id]) . "";
echo "{$workArr['post_text'][$post_id]}\n";
echo "reply to this";
// find all children, call itself on those too
foreach ($workArr['post_id'] as $value) {
if ($workArr['parent_id'][$value]==$post_id) {
processthread($workArr['post_id'][$value], $workArr);
} // end if
} // foreach
echo "";
}

And somewhere in the HTML, where appropriate, the function
processthread is called for the first time passing it the $post_id
value we determined in the first query (the very first post of the
discussion) and the $workArr array.

Use of unordered lists for design/layout is helpful here since
browsers will by default indent lists within lists and list items
within their respective list. This saves some PHP and CSS troubles if
one were to use  or  structure instead, as I found out.

Apologies for any formatting issues and vagaries about the data
structure and variable naming in this post.

- Ben


I think that will work, but there is one huge improvement you can make. 
You are making millions of copies of your work array! Not only do you 
pass the entire array by value recursively, but foreach makes copies of 
the arrays it loops through! So who knows how many copies of the darned 
work array are being spawned left and right. This can be a memory leak, 
consuming lots of memory until it finishes the recursion.


The first thing you can do is tell the function the array is to be 
handled by reference:


function processthread($post_id, &$workArr) {

You never change the work array, I think, so you can just keep referring 
back to the original. The second thing to do is to make the foreach work 
on references instead of copies. I actually think that since what we 
have in our function is now a reference, the foreach WILL NOT copy it. 
But if it still does, there is always the fallback of doing a foreach on 
array_keys($workArr). Then each $value would be the key, which you'd use 
to reference $workArr.

Of course.

As I recall, you HAVE to get the OUTER php page, with the FRAMESET in
it, to start the session, and then in that page, all the FRAME page
requests will be using the same session, because it has already been
established.

I think I even went so far as embedding the session_id in the URLs for
the FRAME SRC="...SID=SID" and then I made sure each frame page was
using that ID.

At the simplistic level, the problem is that you are not using
"return" to actually RETURN the answer, so you do all that work and
throw away the result.

return trim(strip_tags(ucfirst(addslashes($var;

At a higher level, the problem is that you are basically doing several
things very very very wrong here...

#1. addslashes should be replaced with the database-specific escaper,
such as mysql_real_escape_string, or you should use prepared
statements so that the DB cannot possibly mistake data for SQL.

#2. Don't alter the case of the input data, if at all possible. 
Accept what the user has given, and take it as it is.  You can make
your application not care about case, and you can format the case on
ouput (maybe even with fancy CSS stuff) but don't mess with their
input.

#3. strip_tags should probably happen first...  Otherwise the escaping
of the data going into the DB could, possibly, be defeated by clever
arrangement of HTML tags that disguise the invalid data.

#4. There is a complete lack of actual validation here...  You'd be
WAY better off to make sure the incoming data is what you expect, and
not accept bad input, than to just blindly strip_tags on it.

From your code snippet there are clearly too many fundamentals that you

You can.

The thing to do is to store the "pre-order traversal" as a "threaded
tree" in your database.

If you Google for those terms along with SQL, you should find some

Odds are REALLY GOOD that the "or die" is fine...

Try this:  Change line 4 to be:
echo 'Successfully connected: ', $conn;

If $conn shows something like "Resource #4" then you know you have a
good connection.  If it shows "false" or nothing, then you know the
connection is not working, and or die() is doing the right thing.

Except in PHP which supports:

apc optimization is in the words of the author still an experiment -
I don't think it will give you anything much at all at this stage in it's

NB: optimization != opcode caching.

optimization involves juggling the compiled code (the opcodes) so that
they do [exactly] the same in less operations

opcode caching involves caching whatever [possibly optimized] opcodes were
created when compiling a script so that second and subsequent calls to a script
can skip the compile stage completely (which would mean that if an opcode cache
was in affect the optimization would also only need to occur 'once')

find the file named apc.php and use it (as documented) to discover exactly
what apc is doing on your setup... my guess is that apc is caching opcodes for 
you
(given the settings you mentioned) and that your Zend setup does not include
an opcode cache [but it is optimizing whatever is being compiled] - my 
knowledge of
the Zend stuff is patchy at best - I don't really know which of their various 
packages
offer what kind of functionality.

So you end up with this:

value="905.362.6000"1""s"'L'"
   ^
And, in HTML, this | marks the end of the string.

You know how you do mysql_real_escape_string to put data in a database?
In the same way, you need http://php.net/htmlentities to put data into
HTML.

In fact, if you think about it, almost every time you put data from
point A to point B, you need to "escape" it for that specific usage.

data -> MySQL : mysql_real_escape_string
data -> HTML : htmlentities
data -> URL : urlencode

You can frequently "get away" with not doing the escape only because
the data doesn't happen, by mere chance, to have any 'bad' characters
in it.

That doesn't make your code correct.  It just happens to sort of work.

RE: [PHP] Displaying data from a MySLQ table

2006-06-30 Thread Richard Lynch



The fact that you are calling stripslashes tells me that one of two
things has occurred.

#1.
You escaped data coming into the DB *twice*, which often happens with
Magic Quotes GPC + (addslashes || mysql_real_escape_string) used
together.
Your data is corrupt, and until you fix that, you'll just have
nightmares.

#2.
You just don't understand the purpose of escaping data to go into MySQL.

The purpose of the escaping is not to STORE the data with extra slashes.

The purpose is to add extra slashes so that MySQL parser/reader can
"eat" them and end up with the correct raw data you had before you
escaped it.




RIGHT WAY
Raw Data Escaped Data What MySQL puts on hard drive
can'tcan\'t   can't

WRONG WAY
Raw Data Doubly-escaped   What MySQL puts on hard drive
can'tcan\\\'t can\'t

If you're getting can\'t "out" of MySQL with mysql_fetch_row, then you
are in situation #1.

If you don't but you are calling stripslashes() anyway, you are in
situation #2

[PHP] Update or add?

2006-06-30 Thread Brian Dunning

I have a table where I want to update each record with today's date  
as it's hit, or add the record if it's not in there:


+--+-++
|  id  |  creation_date  |  last_hit  |
+--+-++

I'm trying to do this with a minimum of hits to the db, so rather  
than first searching to see if a matching record is in there, I  
thought I'd just go ahead and update the matching record, check to  
see if it failed, and if it failed then add a new one, like this:


$id = $_GET['id'];
// Update
$query = "update table set last_hit=NOW() where id='$id'";
$result = mysql_query($query);
// Add
if(the update failed) {
  $query = "insert into table (id,creation_date,last_hit) values  
('$id',NOW(),NOW())";

  $result = mysql_query($query);
}

What's the fastest way to check if the update failed?

The second thing to do is to make the foreach work

Anyone have any ideas on this? Is the foreach loop in fact copying
$workArr? And how could we tell (test for it) if it were?


I should note that the DEFAULT behaviour of foreach is to make a copy of 
the array you pass it. What I'm saying is that, now that we're passing 
it a reference to an array instead of an actual array, is that enough to 
stop it from copying? The manual seems to indicate that, but is a bit vague.





But if it still does, there is always the fallback of doing a foreach on
array_keys($workArr). Then each $value would be the key, which you'd use
to reference $workArr.


I'm sorry, you lost me here a bit.



I mean, do this:

foreach ( array_keys($workArr) as $key ) {
echo $workArr[$key]['foo'];
}

instead of this:

foreach ( $workArr as $key => $value ) {
echo $value['foo'];
}

Both let you do the same thing, you just reference data differently, and 
the first example involves working with the original array, so foreach 
has no chance to copy it. HOWEVER, if my above supposition about foreach 
not copying a reference is correct, you wouldn't need to do this. It's 
just a backup plan.

Maybe you should be looking at using REPLACE instead of INSERT or UPDATE.
REPLACE will update the record if it exists, OR add it if it doesn't.

This is from the php.net docs.

Return Values

For SELECT, SHOW, DESCRIBE or EXPLAIN statements, mysql_query() returns a 
resource on success, or FALSE on error.

For other type of SQL statements, UPDATE, DELETE, DROP, etc, mysql_query() 
returns TRUE on success or FALSE on error. 
 

So if($result == 0){
do something;
}

No no no no no! Never like that! What you want is this:


if($result === false){
do something;
}

Never use 0 as a placeholder for false, and never use == to compare 
boolean values. 0 is an integer, false is a boolean. Using === ensures 
that result is false, and that it is a boolean that is false. It 
compares the value AND the type.

Okay, I think I get the idea.

So using my code example...

this:

foreach ($workArr['post_id'] as $value) {
if ($workArr['parent_id'][$value]==$post_id) {
processthread($workArr['post_id'][$value], &$workArr);
} // end if

would become this?:

foreach (arraykeys($workArr['post_id'] as $key) {
if ($workArr['parent_id'][$key]==$post_id) {
processthread($workArr['post_id'][$key], &$workArr);
} // end if

Seems to work just fine. Will take the hamsters running in my brain a  
little more time to fully understand it... :-)


Thanks again for all your help.

Hi All,

there is not-so-used format of SQL format that is

INSERT INTO table SET col1=data1, col2=data2... ON DUPLICATE KEY UPDATE 
col1=data1, col2=data2...;


you have to define a primary or unique key in the table and all will 
work well. for more info

I think the point here is that you said [1] and [2], but you still haven't 
provided an example.

The following works just as well as your elseif example.

switch (TRUE)
   {
   case isset($_POST['id']:
  $id = $_POST['id'];
  break;

   case $_POST['action']=='add':
  $id = generate_id();
  break;

   case  (potential_other_test_to_detect_other_valid_states()):
  break;

   default  KaBlooie();
  break;
   }

Additionally, in my timed tests, I find both control structures to be generally 
equal in speed -- so I don't find any support for elsif being better matched 
than switch in any equality based computations.

So, I believe the choice to use one control structure in preference to the 
other is purely a personal one -- and one that has no support stemming from any 
performance differences, because there are none.

Thanks for your reply.
