[PHP] Re: Going through 2 arrays at once

Greetings,
PHP Rookie here with a quick question - how do I go through 2 arrays at
once with different keys?
I'd like to combine these 2 arrays into one:
for ( $i = 0; $i sizeof($logicalDrive); $i++) {
echo $arrLogDrive[$i]br /\n;
}
for (reset($logicalDrive); $i = key($logicalDrive); next($logicalDrive))
{
echo $i: $logicalDrive[$i]br /\n;
}
The first array returns things that the OID in the second array
represent. I.E. $array = array( 1= 'Controller Index:', 'Drive Index:',
Fault Tolerant Mode:', etc, etc);
While the second has the MIB name as the key, then the return value of
the snmpget:
CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1: 0
CPQIDA-MIB::cpqDaLogDrvIndex.0.1: 1
CPQIDA-MIB::cpqDaLogDrvFaultTol.0.1: mirroring
What I'd like to do it replace CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1
that gets displayed into the Controller Index: in the other array.
I hope this makes sense. Sorry if it's super simple to solve, but I
tried a few things, and googled a few things, but I must have not found
the right thing I was looking for, as I still can't figure it out.
Thank you very much!

It sounds like you want to use a while loop and then iterate manually
through both arrays, iterating both arrays once per loop iteration.
Sorry if I've misunderstood the problem.

Something like this below would work, but I'm wondering if there is
something I could do differently in the date() fuction to make it work:
$date = date(a);
if ($date == am)
{ echo a.m.}
elseif ($date == pm)
{ echo p.m.}
The date function itself doesn't support it, but you don't need IFs.
To replace your example: echo str_replace(array(am, pm),
array(a.m., p.m.), date(a));
And to do the replacement on a full data/time:
echo str_replace(array(am, pm), array(a.m., p.m.), date(g:i a));
which would output something like 12:52 p.m.

The idea is to get TCP tunneling working, once you do that you can rely on other programs to use that TCP tunnel for more complex things, like SOCKS. You're trying to get a square peg through a round hole. The HTTP protocol was not designed to do anything like this, so the standard implementation by most web servers and PHP does not allow what you are trying to do. That's the fun of it, making things like PHP and HTTP do things they weren't supposed to. I'm curious about your 'lots of POSTs' solution. How are you keeping the connection open on the server-side? It's certainly not possible to maintain that connection between requests without using a process outside the web server that maintains the connections. I've implemented a system in the past to proxy IRC, MSN and AIM connections in this way, but it only worked because the requests that came into PHP got passed to this other process which held all the connections and managed the traffic. And yes, it did generate a huge amount of traffic even when it wasn't doing anything due to the need to poll the server for new incoming messages. With the lots-of-posts, the connection is a regular keepalive, which any webserver happily keeps open. When this keepalive connection closes, you open a new one. At least this way, while I still need to send lots of posts (Say, one every 100ms, or 250ms, something like that), I can limit the new connections to once every minute or two. While 4 messages per second may seem like a lot, I would imagine that an application such as Google Maps would generate a LOT more than that while a user is scrolling around; google maps would have to load in dozens of images per second as the user scrolled. Polling for incomming messages isn't a problem, as there is no incomming data for the POSTs. A seperate GET request handles incomming data, and I can simply do something like select, or even something as mundane as polling the socket myself. But I don't need to poll the server. And, the 4-per-second POST transactions don't need to be sent unless there is actually data to be sent. As long as a keepalive request is sent to make sure the remote server doesn't sever connection (My tests show apache 2 with a 15 second timeout on a keepalive connection), there doesn't need to be any POSTs unless there is data waiting to be sent. Of course, this solution has high latency (up to 250ms delay), and generates a fair number of POST requests, so it still isn't ideal. But it should work, since it doesn't do anything out-of-spec as far as HTTP is concerned. This demonstrates a point at which you need to reconsider whether a shared hosting environment (which I assume you're using given the restrictions you've mentioned) is enough for your purposes. If you had a dedicated server you could add another IP and run a custom server on it that would be capable of doing exactly what you want. In fact there are lots of nice free proxies that will happily sit on port 80. However, it's worth nothing that a lot of firewalls block traffic that doesn't look like HTTP, in which case you'll need to use SSL on port 443 to get past those checks. I wasn't targetting shared hosting environments. I imagine most of them use safe mode anyhow. I was thinking more along the lines of somebody with a dedicated server, or perhaps just a linux box in their closet. The thing is, I'm not writing a web proxy. I'm writing a tunneling solution. And, the idea is that firewalls won't block the traffic, because it doesn't just look like HTTP traffic, it really IS HTTP traffic. Is a firewall really going to block a download because the data being downloaded doesn't look legitimate? As far as the firewall is concerned, it just sees regular HTTP traffic. And of course, a bit of obuscation of the data being sent wouldn't be too hard. The idea here is that no matter what sort of proxy or firewall the user is behind, they will be able to get a TCP/IP connection for any protocol out to the outside world. Even if the user is sitting on a LAN with no gateway, no connection to the internet except a single proxy server, they should still be able to make a TCP/IP connection by tunneling

Ideally, there should be no delay between the client wanting to send data and the data being sent over the connection; it should be as simple as wrapping the data and sending. So, I need some way to send data to a PHP script that lives on a webserver without any buffering going on. My backup approach, as I described in another mail, involves client-side buffering and multiple POST requests. But that induces quite a bit of latency, which is quite undesirable. How much data are you sending? A POST shouldn't cause that much delay unless your talking about a lot of POST data Curt. Please see my more recent messages on the subject for the reasoning behind this. It's interactive data being sent that may require an immediate response. If a user is tunneling a telnet session, they expect a response within a matter of milliseconds, not seconds. POST holds onto the data until the client is done uploading, which with a persistant POST request never happens, which is why I spoke of multiple POST requests above and in more recent messages.

[PHP] Re: str_replace(), and correctly positioned HTML tags
Dave M G wrote: PHP list, This may be a simple matter. Please feel free to tell me to RTFM if you can direct me to exactly where in the FM to R. Or, alternately, please use simple explanations, as I'm not an experienced PHP coder. I'm building a simple content management system, where users can enter text into a web form. The text is stored in a MySQL database. The text should be plain text. When the text is retrieved from the database for display, I want to add some HTML tags so I can control the format with an external CSS. I'm assuming the best way to do this is with str_replace(). But there are some complications which make me unsure of its usage. First, here is the code I initially made: $content = p . str_replace(\r\n, /p\np, $text) . /p\n; echo $content; The problem is that I want to give the users the ability to add text that will be converted to h3 tags. I figure the best and easiest way to do this is give them some text markers, like --++ and ++-- that can be converted to h3 and /h3 respectively. So I guess I do: $content = str_replace(--++, h3, $text); $content1 = str_replace(++--, /h3, $content); $content2 = p . str_replace(\r\n, /p\np, $content1) . /p\n; echo $content2; But of course a user is likely to put their h3 heading at the beginning of their text. Which would generate: ph3Heading/h3text text text/p That's not good. What I need is: h3Heading/h3ptext text text/p And figuring out how to do that was where my brain stopped. I need to be able to account for circumstances where it may not be appropriate to arbitrarily put a p tag at the beginning. As well as h3 tags, there may also be things such as images and hr lines, but they are all similar in that they will take some text code and convert into an HTML entity. I need to be able to separate those out and then be able to place opening and closing p tags at the right place before and after paragraphs. Is there a way to do this? Is there a good tutorial available? Any advice appreciated. Thank you for taking the time to read this. -- Dave M G It seems like your life would be a lot easier with break takes instead of paragraph tags. Break tags behave like newlines, so work rather well for a 1 to 1 correspondance when turning \r\n into br /. This way, you don't have to worry about the opening tags. The fastest way to do this may be the function nl2br(), which takes only one parameter, your string, and returns your string with the newlines replaced by break tags. Another piece of advice is that you are creating a lot of strings. Do you need the string $text to be unmodified? Why don't you do this: $text = str_replace(--++, h3, $text); $text = str_replace(++--, /h3, $text); $text = p . str_replace(\r\n, /p\np, $text) . /p\n; echo $text; Remember that PHP works by value, not by reference. So what happens in that first line is that it makes a copy of $text, does the replacement on that copy, and then overwrites $text with that copy. With your method you are creating a bunch of strings that I would imagine go unused later in your script. Since you seem to want to maintain a newline in the HTML source, nl2br might not be exactly perfect for you. Here is your original code modified to work with break tags: $text = str_replace(--++, h3, $text); $text = str_replace(++--, /h3, $text); $text = str_replace(\r\n, br /\n, $text); echo $text; And here is the same code using arrays and one single replace instruction to do it, since replacement order doesn't matter: $text = str_replace(array(--++, ++--, \r\n), array(h3, /h3, br /\n), $text); echo $text; And of course, if you never do anything with your formatted string except echoing it out, don't store it, just echo it: echo str_replace(array(--++, ++--, \r\n), array(h3, /h3, br /\n), $text); So, to sum up my advice: 1) Don't create extra variables that you will never use 2) Consider using break tags instead of paragraph tags, they're easier to deal with in your situation. 3) Use arrays for replacement when appropriate 4) Don't store data if you're only ever going to echo it out right away and never use it again. I think that's it, unless I missed something. Regards, Adam Zey. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

One difference though is I used preg_replace_callback (http://us2.php.net/preg_replace_callback) so that I can do custom scripting with the matched string to be replaced. I know I'm entering this discussion a bit late, but one tool that I've found indispensible in writing regular expressions (even after knowing how to write them) is The Regex Coach (http://www.weitz.de/regex-coach) (Free, and runs on Windows and Linux). Essentially, you paste the text to search into the bottom textbox, and then start typing your regular expression into the top one. As you type, it shows you what it is matching in the bottom one. It can also show you what individual submatches are matching, and all sorts of neat stuff. So, if I have an HTML web page and I want to suck some specific information out of it, I'll paste the information in, write up a regex, and make sure it's matching what it's supposed to. But the feedback AS you're typing it is super handy. For example, if I have a regex, and I add a [a-z], then the indicator will show it matching the next character, then if I add *, the text selection will expand to show it matching the rest of the letters, and so on.

**NEVER** use regular expressions for simple search/replace

should be avoided if at all possible. What you are doing is a very
simple string replace, and you should not use regular expressions for that.
I am assuming you want to remove the ! and ? and not replace them with a
space. In this case:
$str = str_replace(array(!. ?), , $str);
Or if you did want to replace them with a space:
$str = str_replace(array(!. ?), , $str);
This is especially important if you're doing the string replace in a

expressions for such a simple replacement.

This is all in the manual...
Essentially you want pcntl_fork(), although you might want to use
something like stream_socket_pair() to do interprocess communication.
You should be able to find all the documentation and examples you need

PHP is a server side scripting language, so the information would not be
sent to the browser( aka client) until the server side script has
completed its execution.
-Brad
That is incorrect. There is nothing stopping a PHP script from doing
exactly what he says, and being a server-side script doesn't imply that
the data will be buffered.
I suggest that both of you examine the contents of
http://www.php.net/manual/en/function.flush.php for more information on
obstacles to getting data to the client as it is generated.
As an unrelated note, there is no point in using print for some things
and echo for others. For your uses, you might as well just use echo
for everything.

I getting a really hard time doing this. I thank any imput you guys can give me. Thanx, Rodrigo First, get the file using file_get_contents(). Now, do two nested regular expression matches. As in, do a regular expression match to get all the select/select blocks, and then for each match do another regular expression match to grab all the option blocks. Alternatively, you could do this with strpos(), since it lets you specify where to START searching from. It might be faster, but it would probably end up being less flexible. Alternatively, if you need a super robust solution, you might want to look into actual HTML parsing libraries, like tidy (which has a PHP module).

something...
Thanks,

HTML can't be parsed line-by-line since even a single tag can be broken
up onto multiple lines. And also, if ($line[85]) simply checks if
there is a character in position 85 of the line. It looks like your code
is reading in a file, checking if each line is at least 85 characters
long, and then writing it out again.
I suggest you read in the whole file using file_get_contents(), and then
do the regex matching or strpos matching that I described in my previous
message. Also keep in mind that as of PHP 5 there is a
file_put_contents() function that lets you dump out a file in one go
(with higher performance than doing it yourself). php_compat also has a
copy of that function for other versions of PHP, although of course they
do it in PHP code so the performance benefits are slightly less.

Assuming allow_url_fopen is on.
If not, you could try using curl - see http://www.php.net/curl
allow_url_fopen is on by default, and curl requires custom compile-time
options. Considering that, it is logical that if the user can't enable
allow_url_fopen, they're not going to be allowed to recompile PHP.

If you're going to be using 5.1.2 in production, develop on 5.1.2. PHP
doesn't guarantee backwards compatibility, especially in such a big
change as 5.0.x - 5.1.x. Better to develop on 5.1.2 from the start than
to develop on 5.0.5, put the code on 5.1.2, get a bunch of errors, and
then have to develop again on 5.1.2 to fix the bugs. Not to mention that
any testing done with 5.0.5 is invalid since you can't be sure that
things will behave the same with the different production version. You
may even waste time working around bugs in 5.0.5 that don't exist in 5.1.2.

1. Incrementing strings: Best example giving was File1++ == File2 or FileA++ ==
FileB. In that case, wouldn't you want it to go from FileZ to FileAA? Makes sense right?
2. Comparing greatness of strings: Rasmus mentioned this earlier, but I
wante to illustrate it a little more because I think it was overlooked. If you have a
list of names, for instance, and you alphabetize them, you'd get something like this:
Bob
Brendan
Burt
Frank
Fred
Just become a name is longer doesn't mean it comes after the rest of the names in the list. So in that vane,
anything starting in A will never be something starting with a Z. a z aa
z aaa z because:
a
aa
aaa
z
When using interation and a for loop and = z it gets to y and it's true, gets to z and it's still true, then
increments to az and yup.. still z. As mentioned, it's not until you get to something starting in z with something
after it that you're z.
So hopefully that makes a little more sense.

If it is a network socket, and the remote end disconnected unexpectedly (which you MUST assume is a possibility), then the only way to find out if the connection is still open is by SENDING data. Just trying to read it won't cut it. The thing to understand is that when a remote client/server disconnects, it normally safely closes the socket and notifies you. But an abrupt disconnection (Something crashes, loses connectivity, etc) sends no such thing.

In any event, I simply want my php application to run another, like so:
switch (option)
{
case a:
run a.php;
exit;
break;
case b:
run b.php;
exit;
break;
case c:
run c.php;
exit;
break;
}
I know that from within an application I can run another php application via a user click
(.e., button), or from javascript event (onclick), or even from cron. But, what if you
want to run another application from the results of a calculation inside your main
application without a user trigger. How do you do that?
I have tried header(Location: http://www.example.com/;); ob_start(),
ob_flush() and such, but I can't get anything to work.
Is there a way?
Thanks.
tedd
See the documentation for include(), include_once(), require(), and
require_once().

Jeff Lewis wrote: I have been working on a script to parse a CSV file and in the process I clean out a lot of the garbage not needed but I am a bit stumped on one aspect of this file. It's a list of over 3000 contacts and I'm trying to mask a lot of the information with *. So as I loop through this list I am checking the array elements as if I find a phone number (555) 555-1212 (I was searching for the (555)) I want to convert it to (555) ***- For fields not containing an area code, I wanted any text to be replaced by an * except for the first and last letter in the element. I'm stumped and was hoping that this may be something horribly simple I'm overlooking that someone can point out for me. This will take a string and replace everything but the first and last characters. $string = substr_replace($string, str_repeat(*, strlen($string)-2), 1, -1); It seems like you want to do it based on letters though, so Hello, World! would become H**d!, not H***! (which the above would do). To do this you'll need to get the positions of the first and last letters in the string and use those instead of 1 and -1. Off the top of my head I don't recall any functions that can do this, strpos and strrpos don't take arrays as parameters. You may be better off with regular expressions for the actual replacement unless somebody knows of a function to get the positions. BTW, in functions like substr, specifying -1 for length means keep going until the second to last character.

[PHP] Re: running conditions while looping through arrays....
IG wrote:
I want to run filters on an pop3 inbox.
I have the following arrays which I'll get from the database-
$subject
$email
$body
$subject_like
$email_like
$body_like
I then go through each email in turn using this loop-
$popy = {.$pop3./pop3:110}INBOX;
$mailbox = imap_open($popy, $un, $pw);
$num_messages = imap_num_msg($mailbox);
if ($num_messages = $no_srch) {$rrt = 0;} else {$rrt =
$num_messages-$no_srch;}
for($i=$num_messages; $i($rrt); $i--) {
What I want to do is to check if the email address or subject or body of
each email is exactly like any of the details stored in the arrays
$subject, $email, $body and to check if the email address or subject or
body contains a word or phrase from the arrays $subject_like,
$email_like, $body_like.
For example-
$subject[0] = SPAM; $email[0]= ;
$body[0] = ;
$subject_like[0] = ;
$email_like[0] = ;
$body_like[0] = ;
// If the subject of the email = spam
$subject[1] = ; $email[1]= [EMAIL PROTECTED];
$body[1] = ;
$subject_like[1] = ;
$email_like[1] = ;
$body_like[1] = ;
// if the email address of the email = [EMAIL PROTECTED]
$subject[2] = ; $email[2]= ;
$body[2] = spam body text;
$subject_like[2] = ;
$email_like[2] = ;
$body_like[2] = ;
// if the body of the email = spam body text
$subject[3] = SPAM; $email[3]= [EMAIL PROTECTED];
$body[3] = ;
$subject_like[3] = ;
$email_like[3] = ;
$body_like[3] = ;
// if the subject of the email = SPAM AND the email address =
[EMAIL PROTECTED]
$subject[4] = SPAM; $email[4]= ;
$body[4] = ;
$subject_like[4] = ;
$email_like[4] = ;
$body_like[4] = spam text;
// if the subject of the email = SPAM AND the body contains spam text
If any of the above conditions are met then the email message is then
stored in a database and deleted of the POP3 server.
Is there a quick way of doing the above? The only way I can think of is
by looping through each array for every email. This is really really
slow. I'd be grateful for some help here
Ian
Unless I'm mistaken,
for ( $x = 0; $x count($subject); $x++ )
{
if ( $subject[$x] == SPAM || $email[$x] == [EMAIL PROTECTED] ||
$body[$x] == spam body text)
{
# Mail is spam! Do something.
}
}
Or something like that. I'm not exactly sure what your criteria are.
What I'm doing above is looping through the mail messages one at a time,
and checking all aspects of that email in each loop iteration. If you're
doing complex analysis on each message, then that is probably the
fastest way.
If you're simply searching for things, you could always do array
searches. So, search through $email with array_search or perhaps
array_intersect. Then you don't need to loop at all.

Querying all data in the first place is a waste, and the practice of
seeking through a dataset seems silly when MySQL has the LIMIT feature
to specify which data you want to return.
I believe the proper way to do this would be something like this
(Simplified example, of course):
$query = SELECT SQL_CALC_FOUND_FOWS * FROM foo LIMIT 30, 10;
$result = mysql_query($query);
$query = SELECT found_rows();
$num_rows = mysql_result(mysql_query($query), 0);
That should be much faster than the methods used by either of you guys.
As a comment, it would have been better to do SELECT COUNT(*) FROM foo
and reading the result rather than doing SELECT * FROM foo and then
mysql_num_rows(). Don't ask MySQL to collect data if you're not going to
use it! That actually applies to why you shouldn't use mysql_data_seek
either.

[PHP] Re: shutting down a web app for maintenance
Shutting down Apache would do the trick ;) But if you're in a shared hosting environment that may not be possible. As for sessions, it depends how you track them. You can't kill all PHP sessions in one go, but you could have your web app nuke the sessions of users after they come back after maintenance. Something like first_login_after_maint in the database, that if set to true, mandates that any existing session data be destroyed before continuing. I assume that the reason you want to kill session data is because the data and how it is used would be different after the maintenance? Because otherwise, if you've denied all access to ANY of your webapp's php scripts, it shouldn't matter if the user has session data. If you physically move the web app's PHP scripts (Or set up a redirect, etc), they can't do anything with it. Regards, Adam Ben Liu wrote: Thanks Adam, What you say makes good sense to me.

If you really want to keep the p?name syntax, I would suggest throwing them in
an array with keys.
$arr[p1name]
$arr[p2name]
Then that way you can create the key dynamically:
$arr[p.$i.name]
Not pretty, but it works.
Thanks,
I haven't checked this, but couldn't you reference it as $arr[p$iname]
? Is there a reason why variable expansion wouldn't work in this

If it does, you could make it easier to read by doing $arr[p{$i}name]
even though the {} aren't required. It'd be a lot easier to read than
concatenations :)

You shouldn't rely on what other languages do, but the one you're working with; PHP has no explicit data-types and manages strings as PERL does. Just as you say there's a reason why == supports strings, there's also a reason (or more) for strcmp() to exists --it's just safer to use strcmp() instead of ==, e.g: 24 == 24/7 Safer, yes. And it'd be even better to do 24 === 24/7, in which case you don't need a function call, it's probably faster (I'd imagine that comparing equality is faster than finding out HOW close it is like strcmp does), and as I mentioned, easier to read.

You almost never need that information, in which case you're wasting processing time with a function call that does something that you don't need. Come on, face it, how many times have done anything with strcmp's return value OTHER than checking that it's zero? I bet the cases are fairly rare. Not to mention the fact that it leads to harder to read code. Which of these has a more readily apparent meaning? if ( strcmp($foo,$bar) == 0 ) if ( $foo === $bar ) That might be true, either way you need to know the language to understand what the first line does and that the second isn't a typo. === is a basic operator. One has to assume that somebody writing code is at least familiar with the basic operators. If not, well, asking them to know what the function strcmp does and what it means when it returns zero is just as onerous. If not more so.

should.
I'm trying the foreach function and key values, but I'm clearly not

But instead, I get:
val[type] = 2
val[resource] = 2
Am I still not doing the foreach correctly?

Dave M G
First of all, you're using invalid syntax. You should have $val['type']
rather than $val[type].
Second of all, mysql_fetch_array returns only a single row, $elements.
This is an array. From there, you're asking foreach to return each
element of the array as $val. So each time through the foreach loop,
$val will have the contents of that element. The element isn't an array,
it's a scalar. So you're taking a scalar and trying to treat it like an
array.
You really should read the manual, the pages for all these functions
describe EXACTLY what they do.
Remember that mysql_fetch_array returns an associative array. You can
refer to the SQL fields by their names. So if your select query was
SELECT foo, bar FROM mytable, after doing a mysql_fetch_array you
could do this:
echo $row['foo'] . br /;
echo $row['bar'] . br /;

For example, would this mysql query get executed if $number = 0 ?
If ($number == 1) {
mysql_query($blah)

Stuff inside an if statement will be compiled (So it has to be free of

Is there anything I can do from PHP or elsewhere to solve this? yes. lets start by saying that any webpage script that takes that long to run is shit by design. what I would suggest is that you run a script via cron that generates a static page which you can then view whenever required; let the cron job run at what ever interval is required/possible. your database maybe be in bad shape - check you have indexes on all the fields your searching/joining on (as a first step) another alternative would be to break down the output of the script into several pages. sorry I don't have a real solution with regard to forcing the browser to keep suckig on the connection. maybe someone else with more fu does. John Gunther Bucks vs Bytes Inc You can run DB queries asynchronously and periodically send invisible HTML (IE, font/font) to the browser every few seconds. But Jochem is right, there are exactly zero cases in which a web application should have page times measured in minutes. At that point, you're doing something wrong. Either your database is poorly designed and needs optimization, or you need to look into how you deliver data to the client. Even if a page is meant for internal use, if it takes longer than a second or two to load, I usually start looking into optimizing or another way of getting the data. I often spin big operations off into cron jobs so that the data or operation is already available by the time a user loads the page. Looking into the database angle, even complex queries against databases with millions of rows should happen almost instantaneously with proper indexes and structure. I used to run a site that had about 15 thousand rows. A single table, very simple queries. And yet, those queries started taking several SECONDS to accomplish as the table grew. By the simple act of throwing in a few well placed indexes, times dropped from seconds to milliseconds, improving by orders of magnitude. I further sped things up using the MySQL query cache, and by doing all my SELECT queries against a HEAP table (a MySQL table stored entirely in memory), while updates and inserts went to disk and then were mirrored back into the HEAP table.

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. It should be noted that you'd need each post to have a sort of superparent field that stored the topmost parent so that you could do something simple like selecting ten superparents and all their children.

Sure, you can send a message attaching the files you want to update in

to retrieve and parse the message to extract the files to be updated.
You may want to try this POP3 client class that you can use for that

It provides a cool feature that lets you retrieve messages from POP3

You can also use this message parser class that lets you process your

Take a look at this example that demonstrates how to integrate both

Example 2
Thread1
Post1
Post2 - reply to post 1
Post3 - reply to post 2

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.

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, $workArr) {
echo ul class=\posting\;
echo h3{$workArr['subject'][$post_id]} (#{$post_id})/h3\n;
echo h4by {$workArr['first_name'][$post_id]}
{$workArr['last_name'][$post_id]} .bull; on .
fixdate($workArr['dt_posted'][$post_id]) . /h4;
echo li{$workArr['post_text'][$post_id]}/li\n;
echo h5reply to this/h5;
// 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 /ul;
}
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 $workArr array.
Use of unordered lists for design/layout is helpful here since
browsers will by default indent lists within lists and list items
within their respective list. This saves some PHP and CSS troubles if
one were to use div or p structure instead, as I found out.
Apologies for any formatting issues and vagaries about the data
structure and variable naming in this post.
- Ben
I think that will work, but there is one huge improvement you can make.
You are making millions of copies of your work array! Not only do you
pass the entire array by value recursively, but foreach makes copies of
the arrays it loops through! So who knows how many copies of the darned
work array are being spawned left and right. This can be a memory leak,
consuming lots of memory until it finishes the recursion.
The first thing you can do is tell the function the array is to be
handled by reference:
function processthread($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.

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.
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.

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?
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.

[PHP] Schroedinger's Bug - may require exorcism...
So... I have this script (being called in a perfectly typical way by PHP 4.4.1 through mod_php in Apache 2.0.55) which sometimes runs perfectly, and sometimes chooses, totally haphazardly, to seemingly run itself twice, which of course causes it to die with a fatal error after it tries to redefine some functions. As mysterious as that is, it turns out it must be something altogether more sinister. I tried putting die() at the end of the script, on the assumption that it was for some reason executing twice, yet behold: the problem is still present, and the PHP error log still complains about constants and functions being redefined! The problem, I therefore thought, cannot be that the script is being run twice. (In retrospect, this was the most likely possibility, because the page doesn't actually output anything if it dies with this error.) So for debugging, I added a bit that logs one message to a file immediately before the die() at the end of the file, and a different message after the die(). The die() seems to be working normally, in that it only logs the first message... But wait a second! WTF? If the PHP error log is to be believed, then the script should be dying with a fatal error before it even *gets* to that point in the script, isn't it? And the greater WTF is the fact that, as I mentioned above, every time the page is requested, it unpredictably either does this or works flawlessly. Oh my. How do I even *begin* to debug something like this? Thanks for any help. -- Adam Atlas -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] XML and special characters
I've been having a tough time with parsing XML files and special characters. I have attempted every applicable engine, last try SAX, to attempt at parsing a (rather large, 17.8mb) xml file. The problem I hit, is when it hits a UTF8 encoded character. I've attempted at decoded the file before it hits the parser, I've attempted even ENCODING it (god knows why that'd work, it didnt, lol). I've tried html_entities, etc. Nothing as such has worked. I've also tried simply removing the character, and low/behold, it worked! Darned thing... §µÖÕÔÓÒ Those are the characters so far that have caused me problems. I'd give the utf8 encoded equivalent, but I'm not sure of it off the top of my head. My code, varies so much that I'm not sure it'd be useful to type it out. The issue seems not to be with my code, as when I parse the file manually with a whole bunch of inefficient regex statements, everything works out peachy. The problem with that way again is, it eats system resources for a very long time (remember, 17mb file, and its all plain text? :)).

[PHP] XML and htmlentities conditionally?
I have a block of XML that looks as follows: namelt;*_~_*gt; Røyken VGS lt;*_~_*gt;/name Now, if I run that block of XML through htmlentities, I will get the following: name*_!_* Røyken VGS *_~_*/name XML parsers will return a problem, as there is both an unclosed tag and an invalid tag, in two places no less (however the error will occur on the first tag. In order for this particular XML file to parse properly, I -must- run html_entity_decode. This causes quite the predicament as if I were to then run htmlentities() on this portion of the file, it would produce quite a bit of chaos. My question is, can I in any way efficiently (i -stress- efficiently, if anyone read my previous XML and special characters post its a rather large XMl file (breaking 18mb now) and speed is of the essence) cause html_entity_decode to not decode those tags? Or any other way would be nice too, I'm pretty much open to anything... as long as it doesnt severely hurt the efficiency of the script.

[PHP] Redirection after login with security
Synopsis: I am writing a management system for a MSSql database driven game, and I've run into an issue. The community site is located on a remote webserver, to protect the actual server from any possible vulnerabilities in the community application/forum application (as we all have seen the recent issues with phpBB and various CMS systems). The management system grants the ability to access and modify various properties of your in-game account. In an attempt to provide the best way to limit the # of accounts per person, I assumed that this could be accomplished by placing a dummy value only used by the site itself that is the username/encoded password for them on the community, and test if... when searched for in the database, a result set of x is discovered, then they are unable to create another account. Problem: I would like to possibly utilize a login system (created on the remote server), that would then check their username and password against the CMS database located there, then redirect with that information (encrypted of course), to the local site where the information gets stored in a session. Then when they go to create a new account, it stores the extra verfied information into the database. However, the issue at hand here is, I'm not sure how secure it would be if I were to say, create a secure login form, verify the data... and then create another pseudo form that directs the person to the local-based site using hidden post variables (this is my original thought on the subject). Is there another way I could go about doing this (ie, a way that I could identify a user that is almost assuredly never going to change) or is there a more secure way? Or, am I on the right track?

I suspect it's cause your both checking the variable and setting it in
the same clause.

Hi friends,
I am having a DSL Internet connectivity in our office and my PC is
connected to Internet using a HTTP/FTP Proxy(192.168.0.10) and the
browser(Mozilla) in my PC is configured to connect to net through the
proxy
When I tried to connect to our ftp site using the following script, I
have received the message that Unable to connect. But the same script
is working fine with a direct modem connection.
The script is
// connect to ftp server
if(!($ftp=ftp_connect(ftp.dirw.net)))
{
print(Unable to connectbr);
exit;
}
Please suggest me on how to connect to the ftp site using the proxy
server.
Regards,

You know me, I never ask for help if I haven't checked all my other options, but this is day two, and I'm getting spanked on this one. Some recently moved scripts from a WIN2K server running PHP 4.2.1 to an Apache PHP 4.2.3 setup have stop accepting HTML Form Variables. I can pass variables till I am blue in the face, even see them in the URL but they are still showing up as (!isset) My ISP (Whom is using Virtual Directories) has no solution, and I have tried every code variation I could think of to troubleshoot it. This code has been working fine for Months on the WIN2K box, but just doesn't pass a var on the Linux solution. Can any Server pros out there possibly throw me a bone?

[PHP] How to force an image to reload
Guys, not sure if this is a PHP problem or a more general HTML problem,
but...
I've written a small test script (see below), basically, which allows the
user to rotate an image by 90degrees.
When I press the button, the page reloads having rotated the image, but the
old image is still displayed. (I know it's done it if I load up another
browser window)
Pressing refresh does cause the image to reload.
Any ideas???

As one who has had to do the same thing and had gotten some help from
this list I'll put in my two cents.
? $rand = rand(1000,); ?
img src=image.jpg?? echo $rand; ?
This echoes a ? with a random number behind the filename forcing a request
to the server for the image because you probably wont have that exact same
image with the random number in your cache.

[PHP] Install Problem
I'm attempting to install Pear DataObjects on Windows 2000 Advanced Server with all the most current patches and updates. When utilizing the php-cli exe to run createTables.php, we recieve the error invalid function call to getStaticProperty, in DataObject.php on line 1620. I have attempted to run the DataObjects install script but it gave a warning that the archive was an old format because there was no package.xml. We have downloaded the most recent TGZ and received the same error when installing locally.

Re: [PHP] protect downloadable files
Make the download link a PHP page: download.php?fileid=199 Then check to make sure there session is valid, and what not and then use the header function to make the browser know it's supposed to give a save dialog box.

Re: [PHP] Include?
The passwd file is frequently world-readable so programs that rely on it don't need
root permissions. Now if you can view /etc/shadow, then that would be a problem since
that's where the actual passwords are stored (encrypted).

It seems that if I create a php file in my dir at my hosting provider and do

Is this expected behavior???
I am looking at creating a script that takes a var in the url and includes
the requested file. The purpose would be for only URLs
(myscript.php?page=http://mysite.com/dir/cool.html, or relative URLs
(myscript.php?page=/dir/cool.html).
Can I do this without allowing someone to include files by filesystem
reference???
Thanks!

Re: [PHP] Submitting a Form
1. Try: $_POST[Test]
2. $_POST[testmultiple][2] (Will give you position 3 of the select.)
Or: $list = implode($_POST[testmultiple]);
Will give you the values selected in $list in a comma seperated list.
3. print_r($_REQUEST)

Yet, I continually get the browser message:

1. Any reason that I can not pass the variable to the submit page? I am
using an Apache Web Server on Windows XP. I am simplying attempting to pass
a variable from one page to another, so I can update my database. This is
just a simple test that is failing.
2. If I have a select name=testmultiple multiple HTML tag, how can I
reference the x# of variables that are selected in that form value in the
submittest page? I would want to get every option that is selected in the
page.
3. Is there a variable so that I can see everything that is passed from the
form, some debug variable I could print() to see everything that was
passed from the form?
Anyone have an idea?
