Thodoris wrote: How are your groups linked with your users? Does every user has a GroupId in his record? Does this question has to do with building an html tree or it is about the best database schema that helps to construct and retrieve a tree faster? My users-table is linked to the groups-table via a link table (2 fields, 1 field in primary key). This question is about how to manage "virtual" or "smart" node-items. Node-items that represent something in another table, that will likely change in that table. Like 'users' and 'groups' in the CMS. The solution i'm trying now is to have certain root-nodes that get populated by a custom php abstraction layer. Every node has a type, linking it to rights-management settings (and other things later i assume). And every node has a 'target'. That links 1-to-many to records in tree_target_identifiers table. That table lists fields like table_name, key1_name, key1_value_int, key1_value_vc, etc. I have fields for 2 keys defined in that table. Now the clue of this question is what to do when the user-list changes. With my current solution, unless the user is actually deleted from the system, i wont have to make any changes to the admin tree, since the admin tree will get most of the 'data' for any node from the target tables, whether that be 'users', 'groups' or 'articles'. If the user gets deleted, i could find-and-delete-the-corresponding-node, or i could rebuild that section of the tree (wont do that coz of resources and potential tree size). But in any case the code that deletes a user, group, article, or any other object under the tree's management, will have to call code to update the tree aswell.. Sometimes theres just no way around hard work ;) I've yet to experiment with nested trees and moving items between the nodes.. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'd go with a regular expression any day for something like this.
Something like:
"/$[0-9]{1,3}\.\ .*^/g"
should do what you need. Note the space before the last period.
That would only work for files with 1-999 lines, and will wind up
matching the entire line (since you used $ and ^ and a greedy .*
inbetween... also... $ is "end-of-line" and ^ is "beginning-of-line" :))
rather than just the "line number" part. I would stick with my
originally-posted regex ("/^\d+\.\s/"), but I would modify yours like
this if I were to use it instead:
"/^[0-9]+\.\ (.*)$/" (What was the "g" modifier for, anyway?)
Then, you could grab the capture group made with (.*) and use it as the
"clean" data. (It would be group 1 in the match results and "$1" in a
preg_replace() call, I believe. Group 0 should be the entire match.)

Personally, I would go this route if you wanted to stick with a regex.
This takes care of all possible issues related to the char after the
first period. Maybe it is there maybe not.
Could be that it is a tab and not a space. Could even be multiple
tabs or spaces.
There it goes again.
Every time someone asks a simple question (like the kind it's solved
with a simple trim, ltrim or rtrim) the discussion about which is the
best regular expression for this problem, makes a thread get "elephant"
sized :-) .
I love this list!!
Your not going to be able to get it with any of the xtrim() functions. you
would end up with various nested ltrim() calls that, IMO, would be a
nightmare to manage.
So, a top to bottom comparison here
If $line is this:
$line = '01. asdf';
And you use either one of these:
A) ltrim(ltrim(ltrim($line, '0123456789'), '.'));
B) preg_replace('/^[0-9]+\.\s*/', '', $line);
Which do you prefer?
A's Pros:
Not a regex
A's Cons:
A little slower then B
multiple function calls
B's Pros:
Slightly faster then A
Single Function call
B's Cons:
Regex
You should really check the manual again Jim. AFAIK ltrim doesn't remove
a single character but as long they belong to the list they are all
removed you just do:
ltrim($line, '0123456789')
and this does the job perfectly. So perhaps you need to reconsider your
thoughts on this.

[PHP] Globals or Super Global Variables To Be Reused from For Loops
Hi,
I have a snippet of code as shown in the following:
$message2="47406|Detroit";
$stringChunk2= explode("|", $message2);
if ($message2!="") {
$count_chunk2= count($stringChunk2);
$count_chunk_2= $count_chunk2-1;
}
for ($j=0; $j<$count_chunk2; $j++) {
$string3= $stringChunk2[$j];
if ($j <$count_chunk_2) {
$string2= " OR ";
$string3=$string3.$string2;
}
else {
//Don't do anything
}
echo $string3;
}
The code itself works, but I would like to reuse $string3 variable somewhere
else where I can build SQL statements from it.
I tried using
global $string3;
echo $string3;
after the final curly brace, but I only get Detroit and not "47406 OR Detroit".
Can anyone please suggest me what I should be using here?
Thanks for your help.

Alice,
The big problem here is that you are resetting the $string3 variable in the
loop
for ($j=0; $j<$count_chunk2; $j++) {
$string3= $stringChunk2[$j];// <<<-- resetting
the value
if ($j <$count_chunk_2) {
$string2= " OR ";
$string3=$string3.$string2;
}
else {
//Don't do anything
}
echo $string3;
}
I am not sure of your goal since you have not stated it, but it certainly
should be easier to just replace the PIPE with the OR
$message = str_replace("|", " OR ", $message);

RE: [PHP] Globals or Super Global Variables To Be Reused from For Loops
Hi,
Sorry, I cannot use that because I am supposed to turn the string into
something that looks like regions.name LIKE '%47406' OR regions.name LIKE
'%Detroit', which I had to fix $string3 variable to
$string3="regions.name LIKE '%" . $stringChunk2[$j] . "'";
The goal is that the $message variable would be only a $_POST['message']
variable so that the where clause can be generated dynamically.
The code I have above is part of my where clause in the full SQL statement I
intend to
construct, which means I have to reuse this $string3 variable somewhere
else.
This is what my global declaration looks like:
if ($j <$count_chunk_2) {
$string2= " OR ";
$string3=$string3.$string2;
global $string3;
}
else {
//Don't do anything
}
echo $string3;
}
echo $string3;
The last $string3 echo only gives me regions.name
LIKE '%Detroit' according to the current construct and not regions.name
LIKE '%47406' OR regions.name LIKE '%Detroit'. Is there something else I should
do to have it give me the same output as the echo $string3 as I have had after
the second to last curly brace?
Thanks again for your help.

Maybe instead of saying "AFAIK", you should go and check it yourself. But
obviously, since you didn't care to do it the first time around, I will
supply the relevant parts for you and the list archive. And I quote:
Reference: http://us3.php.net/ltrim
Under "Returned Values" section...
Return Values
This function returns a string with whitespace stripped from the beginning of
str . Without the second parameter, ltrim() will strip these characters:
* " " (ASCII 32 (0x20)), an ordinary space.
* "\t" (ASCII 9 (0x09)), a tab.

Yeah, I think people under-estimate the performance of (SIMPLE) Regular Expressions for text manipulation and searching. As long as you don't have like 15 nested groups and callbacks and optional chars/groups out the wazoo in your PCRE pattern, it will be very quick: it was designed with efficiency and speed in mind. I feel it's also worth mentioning that it may be worthwhile to lean towards RegEx functions for text searching/manipulation so that there is a consistency between methods throughout your code. 15 regex patterns may be better than intermingling xtrim(), strstr(), stripos(), str_replace(), etc... and are probably more easily-readable than scanning 15 10-line algorithms to discern their purpose.

against my better judgment, I believe this is what you are looking for.
# Get your starting string
$pieces = "47406|Detroit";
# Break it into the parts you are looking to use
$parts = explode("|", $pieces);
# Empty temporary array
$tmpHolder = array();
# Loop through parts list
foreach ( $parts AS $part ) {
# Create a single statement and stuff it in your tmp array
$tmpHolder[] = "regions.name LIKE '%{$part}'";
}
# Join all the parts together, placing an OR between each element.
$string3 = join(' OR ', $tmpHolder);

Computer functions to generate random numbers are not designed to do what their
name suggests.
Software testing requires repeatability, and this includes random number
generation.
Without knowing how PHP seeds the generator it is difficult to predict what it
will do.
I still think taking the last digit of the current time is your best solution.

Which PHP version are you running? After 4.2.0, it should be random

Really, you think this step is difficult?
Try looking at the page http://php.net/date it will give you all that you need.
$second = (int)date('s');
This will give you the current second of the current minute of the current
Anyways.
Take that and run it through a modulo then add one to keep it within the 1-10.
This should do

The PHP developers understood the random problem and the need for
predictability, so they did 2 things.
1. Randomly seed the random number generator every time
2. Allow you to set the seed for predictability

of each line. How can I accomplish this?
Opening the file to modify it is easy, I'm just lost at how to
remove
the text.:
I'd go with a regular expression any day for something like this.
Something like:
"/$[0-9]{1,3}\.\ .*^/g"
should do what you need. Note the space before the last period.
That would only work for files with 1-999 lines, and will wind up
matching the entire line (since you used $ and ^ and a greedy .*
inbetween... also... $ is "end-of-line" and ^ is
"beginning-of-line" :))
rather than just the "line number" part. I would stick with my
originally-posted regex ("/^\d+\.\s/"), but I would modify yours like
this if I were to use it instead:
"/^[0-9]+\.\ (.*)$/" (What was the "g" modifier for, anyway?)
Then, you could grab the capture group made with (.*) and use it as
the
"clean" data. (It would be group 1 in the match results and "$1" in a
preg_replace() call, I believe. Group 0 should be the entire match.)
Todd Boyd
Web Programmer
Personally, I would go this route if you wanted to stick with a regex.
This takes care of all possible issues related to the char after the
first period. Maybe it is there maybe not.
Could be that it is a tab and not a space. Could even be multiple
tabs or spaces.
There it goes again.
Every time someone asks a simple question (like the kind it's solved
with a simple trim, ltrim or rtrim) the discussion about which is the
best regular expression for this problem, makes a thread get "elephant"
sized :-) .
I love this list!!
Your not going to be able to get it with any of the xtrim()
functions. you would end up with various nested ltrim() calls that,
IMO, would be a
nightmare to manage.
So, a top to bottom comparison here
If $line is this:
$line = '01. asdf';
And you use either one of these:
A) ltrim(ltrim(ltrim($line, '0123456789'), '.'));
B) preg_replace('/^[0-9]+\.\s*/', '', $line);
Which do you prefer?
A's Pros:
Not a regex
A's Cons:
A little slower then B
multiple function calls
B's Pros:
Slightly faster then A
Single Function call
B's Cons:
Regex
You should really check the manual again Jim. AFAIK ltrim doesn't remove
a single character but as long they belong to the list they are all
removed you just do:
ltrim($line, '0123456789')
and this does the job perfectly. So perhaps you need to reconsider your
thoughts on this.
Maybe instead of saying "AFAIK", you should go and check it yourself. But
obviously, since you didn't care to do it the first time around, I will
supply the relevant parts for you and the list archive. And I quote:
Reference: http://us3.php.net/ltrim
Under "Returned Values" section...
Return Values
This function returns a string with whitespace stripped from the beginning of
str . Without the second parameter, ltrim() will strip these characters:
* " " (ASCII 32 (0x20)), an ordinary space.
* "\t" (ASCII 9 (0x09)), a tab.
* "\n" (ASCII 10 (0x0A)), a new line (line feed).
* "\r" (ASCII 13 (0x0D)), a carriage return.
* "\0" (ASCII 0 (0x00)), the NUL-byte.
* "\x0B" (ASCII 11 (0x0B)), a vertical tab.
Notice the second sentence of the first line?
"Without the second parameter, ltrim() will strip these characters"
That means their is a default set of chars that it uses IF you do not supply a
list of chars.
On a side note. If you notice, under the ChangeLog section, the second
parameter wasn't added until PHP 4.1.0.
What you said was "if they belong to the list they are all removed." Then what
exactly did this this function do before 4.1?
I did my requested homework, but I think you need to go back and study that
chapter now.
This :
ltrim($line, '0123456789 .');
does remove all those characters doesn't it (as the OP asked and Richard
suggested on a previous thread). Without calling it more than once as
far as I tested. That was my point on the first place and sorry if I
didn't make that clear. On the other hand who ever suggested calling
ltrim without the second parameter.
You suggested before something like that:
ltrim(ltrim(ltrim($line, '0123456789'), '.'))

[PHP] PHP and Cyrus problem
Hello, My company have almost ten thousand mailboxes on Cyrus Imap. We use Thunderbird for IMAP client and PHP for webmail. We have a problem in a very few mailboxes. This boxes don't have any visible problem with Thunderbird access but in PHP, the (webmail) access provide a "segmentation failed". If I modify the cyrus.header file the "segmentation failed" problem is resolved. This is a problematic cyrus.header: ¡^B<8b>^MCyrus mailbox header "The best thing about this system was that it had lots of goals." --Jim Morris on Andrew user.02401695bc4b7c0488731c8 0240169 lrswipcda$Forwarded $label1 $label4 $label2 $label3 $label5 $MDNSent NonJunk acade acgap alfredo andre_porto carneiro chevalier cida-bruno cida_coutinho claudia concei&aoca4w-o daniela elaine erlan fazer_reuni&aom-o fernanda godinho helenac inah joao_almeida katia lm luis mara marcio_rfb marco maria_lucia_-_acbsa nelicio pc pendente plinio pp resolvido rwagner tema vinicius-oracle 0240169 lrswipcda If I modify cyrus.header, the "segmentation failed" is resolved, but this generate a Thunderbird labels messages problem.

I'd go with a regular expression any day for something like this.
Something like:
"/$[0-9]{1,3}\.\ .*^/g"
should do what you need. Note the space before the last period.

Your not going to be able to get it with any of the xtrim()
functions. you would end up with various nested ltrim() calls that,
IMO, would be a
nightmare to manage.
So, a top to bottom comparison here
If $line is this:
$line = '01. asdf';
And you use either one of these:
A) ltrim(ltrim(ltrim($line, '0123456789'), '.'));
B) preg_replace('/^[0-9]+\.\s*/', '', $line);
Which do you prefer?
A's Pros:
Not a regex
A's Cons:
A little slower then B
multiple function calls
B's Pros:
Slightly faster then A
Single Function call
B's Cons:
Regex

w/e $all is, im guessing $all->fetch() is never returning false (or a value
which can be type juggled to a boolean false equiv). if youre code is
getting beyond the while loop, then there could be something wrong w/
$all->close(); and if its getting passed that, then obviously, something
else is wrong.

In pseudo code you have:
for each result from the db
explode the issues
add another issue to the list
So:
no issues at start
row 1 fetched
explodes issues
adds another issue (1 issue)
row 2 fetched
explodes issues (now 1)
add another issue (now 2)
row 3 fetch
explode issues (now 2)
add another issue (now 3)
and so on.
So your list is getting longer and longer and you're adding to it for
each row you get from the db.

[PHP] I have a problem with dynamicly updating files...
I got a lot through a tutorial, but problem is when i tried to insert,
problem occured using following code:
$query = "INSERT INTO contacts VALUES
('','$first','$last','$phone','$mobile','$fax','$email','$web')";
mysql_query($query);
But when i used a code provided by my server for same purpose was
sucessful, which was:
$sql = 'INSERT INTO `server account_database name`.`table name` (`id`,
`first`, `description`, `mobile`, `fax`, `email`, `web`) VALUES (NULL,
\'first\', \'$description\', \'$mobile\', \'$fax\', \'ghjhjhg\',
\'ghgjghjghkgk\');';
Now My problem is that :-
It supports only a single or static record at a time & from my
cpanel, but I want that the users of my website can
fill that form and when the click "submit query", then their input
should be added to the table and they can view their data...
I think that , here is a trouble in diff. version. Please If you give
me the code(query").

Your query looks fine. You need to look at the error codes you receive.
change:
mysql_query($query);
TO:
mysql_query($query) or die(mysql_error());
The resulting error message should help you find your MySQL issue.

You can only omit the fields you are adding data to in an INSERT query
if you are inserting data into ALL the fields, and in the order they
occur in the table.
However, I'm not sure quite what your problem is, could you give some
more details?

You have a loop inside a loop. What makes it worse is that the loop is
growing with every iteration.
If there are 100 rows, then at the end, there are 100 entries in the
$issues array.
To get to that point, you are doing a loop of size "X" where "X" = the
row number being processed. ie row "2" is doing a foreach over 2
entries. row 15 is doing a foreach over 15 entries. row 90 is doing a
foreach over 90 entries.

I'm 99% sure you have applied it in wrong place and have your data sent out already destroyed by addslashes. Only 2 places where any escaping should occur: 1. before writing data to storage, use appropriate storage-dependent escaping routine. 2. before sending data to client. Use appropriate encoding routine, such as htmlentites() Don't use add*slashes and any kind of it, including magic_quotes*, unless you surely know what you're doing and why. And please, don't top-post. -- Sincerely Yours, ANR Daemon <[EMAIL PROTECTED]> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That's not QUITE right. The value of $issues will always be set to the
column value for the next row when $all->fetch() is called, therefore
overwriting the value it had after the previous iteration. The
variable $row2 should be set to an empty array before the foreach loop
just in case different rows have different numbers of issues.
Iteration 1:
before foreach
$issues == 'a, b, c'
$i == 0
$iss_link == Array
(
[0] => 'a',
[1] => 'b',
[2] => 'c'
)
$row2 == empty
after foreach
$i == 2
$row2 == Array
(
[0] => 'http://mantisus/view.php?id=a"; target="_blank">a',
[1] => 'http://mantisus/view.php?id=b"; target="_blank">b',
[2] => 'http://mantisus/view.php?id=c"; target="_blank">c',
)
after implode
$issues == 'http://mantisus/view.php?id=a";
target="_blank">a, http://mantisus/view.php?id=b";
target="_blank">b, http://mantisus/view.php?id=c";
target="_blank">c'
Iteration 2:
before foreach:
$issues == '1, 2'
$i == 0
$iss_link == Array
(
[0] => '1',
[1] => '2',
)
/* STILL CONTAINS THE ARRAY FROM THE PREVIOUS ITERATION */
$row2 == Array
(
[0] => 'http://mantisus/view.php?id=a"; target="_blank">a',
[1] => 'http://mantisus/view.php?id=b"; target="_blank">b',
[2] => 'http://mantisus/view.php?id=c"; target="_blank">c',
)
after foreach:
$i == 1
$row2 == Array
(
[0] => 'http://mantisus/view.php?id=1"; target="_blank">1',
[1] => 'http://mantisus/view.php?id=2"; target="_blank">2',
[2] => 'http://mantisus/view.php?id=c"; target="_blank">c',
)
after implode:
$issues == 'http://mantisus/view.php?id=1";
target="_blank">1, http://mantisus/view.php?id=2";
target="_blank">2, http://mantisus/view.php?id=c";
target="_blank">c'
There is the potential for wrong behavior, but it the multiplicative
loops you are talking about shouldn't happen.

Re: [PHP] Infinite Loop Issue
To get to that point, you are doing a loop of size "X" where "X" = the row number being processed. ie row "2" is doing a foreach over 2 entries. row 15 is doing a foreach over 15 entries. row 90 is doing a foreach over 90 entries. That's not QUITE right. The value of $issues will always be set to the column value for the next row when $all->fetch() is called, therefore overwriting the value it had after the previous iteration. The variable $row2 should be set to an empty array before the foreach loop just in case different rows have different numbers of issues. You're right, I missed that $issues was a bind_result. -- Postgresql & php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What the heck is in $db? Which SQL class(es) are you using for your DB handler?

Not sure, but is your bind_results() method handling all the variable here as
pass by reference?
If so, I hope you are not expecting them to be updated as you run the while
loop below...

Usually, a while statement like this looks a little more like this...
while( $row = $all->fetch() ) {

Where are you defining the $issues variable? Where is this coming from?
I see that it will exist on the second pass through, but you need to not cause
a PHP E_NOTICE warning...

Why have a counter here??? php will take care of dynamically added an index to
an array if you call it with $row2[]

Where are the above variables defined/create?
