Obviously the more connections the more of certain resources it will be using, but it doesn't block for every connection. The exception, of course, being if you have something going on at the MySQL protocol level such as LOCK TABLES or a transaction. That will hold up certain other queries.

Reading Ted's post didn't give this impression. I wanted to make sure he wasn't doing it that way. Chris et al: Actually I am. When I need something from the dB, I open it, get the information and close it. It's like opening a drawer, getting what you need, and then closing the drawer. Where's the problem? Uh, what if you want to do more than one query in a single request? You aren't seriously suggesting you would connect and disconnect from the same database multiple times within the same request? In my experience, connecting to the database takes up more than half of the execution time of the average database-driven PHP script (I said *average*, there are exceptions).

That would be a needless BC break. I'm sure that was the thought on magic quotes and register globals also. If PHP didn't close connections at the end of scripts we'd either have just about every script in the world throwing errors when they finished, or lots of memory leaks. Neither is particularly favourable, so I don't think it will happen any time soon... Also, I do it this way because some projects that use my framework want persistent connections. If my framework closed connections automatically then that wouldn't be possible. Your database layer should handle whether a connection is really freed. Just because the developer calls the close() method on your DB object, doesn't mean you need to close the connection. But if they don't call a close() method, then in the future if you do need that functionality... it's not there. Of course, it wouldn't exactly be a rewrite to make it close the connection at the end of every script before PHP did, if I'm proven wrong and it one day is necessary. I'd only need to change the database objects layer. Wrong, you would just be doing the same thing PHP does... closing the connection at the end of the script. What happens if you need to open 20 connections to 20 different databases... are you going to keep them all open? I guess you would since it sounds like you don't have a facility to close them. I don't think what you're doing is incredibly obscene, I mean 90% of PHP developers are doing the same thing. 90% of the coding population can't be wrong... but one that same line of thought... when you open an image file or text file for reading or writing... do you close it? Or just leave it open for PHP to close at the end? I mean PHP will magically close all resources for you, there's obviously no need to close it... or maybe there are valid times when you need to close a resource yourself, I dunno, I feel like I'm out on a limb here ;) Yeah, I can see your point. Simple answer though: my framework isn't designed for connecting to 20 different databases :) It's designed for normal database-driven websites -- where there usually a maximum of two connections (master and slave), and often only one connection, open. I guess I'm just gambling the time-saving benefits of not having to call $db-close() or whatever all the time, against the slim possibility that I might one day have to write a new framework to deal with apps that do 20+ DB connections at once. The framework is fairly light anyway as it's built on top of PDO, so a rewrite is not a huge deal. -- Jasper Bryant-Greene General Manager Album Limited http://www.album.co.nz/ 0800 4 ALBUM [EMAIL PROTECTED] 021 708 334 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Dont know if you guys see the MAJOR difference between your code, so I
will point it out.
Jasper did this
function __get($k) {
var_dump($k);

Uhm, no I didn't. Jochem did :)
Jochem did this
public function __get( $key ) {
return $this-array[$key];

No, I did that.
First off, the required public before the function call was not
included, secondly, Jasper is var_dumping the key of the array, not the
array it self.
Public is not required. I always put it regardless, but if you leave it
off then PHP defaults to public for compatibility reasons.
Jochem's code, which behaves incorrectly, does var_dump. Mine just
returns the array key as you would expect. That's why Jochem's doesn't
behave correctly with arrays.

That's terrible overkill. Regex is not designed for simple substring
matching. You want:
if( strpos( $string, '../' ) !== false )
echo 'string has ../';
By the way, your problem is that . is a special character in regular
expressions, so needs escaping with a backslash, and you have used / as
your delimiter but also use it inside the pattern. You should use a
different delimiter (also, there's no point in using the 'i'
case-insensitive flag, since there's no characters in your pattern).
The strpos() solution above is much better and faster in this case, though.

here you store an empty array in the $vars member array, under the key

now you are adding elements to this array under the 'arr' key in the

if (isset($tc-arr['b'])) {
unset($tc-arr['b']);

you just removed b from the array under 'arr' in the $vars member array.
//var_dump is only to see results of above

this should show something equiv. to:

what does it actually show?

Re: [PHP] HTTP status code
The default Apache error handler is not called when PHP sends a 404
header. The code that does Apache error handling happens *before* PHP
gets in the loop, and checks to see if the script being referenced
exists, which it indeed does, whether it sends a 404 header or not.
Tested on Apache 2.2 with PHP 5.1.
If you really want to get the default Apache error handler to appear
then either readfile() it or redirect to it.

While this seems like excessively ugly code (have you considered an
array? what is the point of all those variables if they all hold the
same value?), replace all of those '' with '=' and you will be fine.
PHP evaluates right-to-left and the result of an assignment is the value
that was assigned, so that will work.

I think what you are trying to do is coordinated a bit wrong, perhaps

Taking a look at your query, i do see what you are trying to do, but the
structure is wrong.
$query = INSERT INTO users (avatars) VALUES ('$avname')WHERE id
='$user_id');
Also - it looks like an UPDATE might be more suitable for what you want,
given that you've got a WHERE clause tacked on the end. Google for a
good SQL tutorial; the PHP mailing list is not the place to learn SQL :)

Yes, your friend (or anyone who compromises his server, who may very

You could do:

[PHP] Execute a program from PHP CLI and allow user interaction
Hi all
This one's got me stumped. I'm working on a PHP CLI interface, and I
need to allow the user to input a bit of HTML.
Rather than bandy around with readline() and the like, I thought it
would be nice to just create a temporary file, pop nano up, and read and
then delete the file once it's been edited. That way I get nano's syntax
highlighting and other useful features.
However, I can't for the life of me figure out how to allow the user to
interact with nano once the process has been launched. The usual culprits:
{exec,system,shell_exec}( nano tmpfile.txt );
all just hang (top shows nano is running, but it doesn't seem to be
attached to the terminal).
How can I launch a process and attach it to the terminal PHP CLI was
launched from so that the user can interact with it?
TIA

The difference between POST and GET lies in the semantics -- POST represents something changing on the server, e.g. updating a database field, and allows the browser to warn the user if they try to refresh. GET represents nothing of importance changing on the server, e.g. performing a search on the database, and can safely be repeated.

This ftp account points to a directory that PHP can have access to. The user then drags and drops (IE only) the files on this new window, which uploads the files to this directory. Once they're done, they close the window, and hit a second button 'Click here when finished uploading' which tells php to grab all the files in the upload directory and put them where they need to go. This is far from ideal, causes miserable problems when more than one person is using the technique at once, and offers a host of security and usability issues. Oh, and it's IE only, Firefox can't do this, and I don't think opera/safari can either. However, it's much better than uploading a ton of files individually using a form.

If your table isn't too big, it's fine to do:

If you've got more than a few 10,000s of rows, you might want to look at
other ways, like selecting a random row based on the primary key by

If you are attempting to access the variable $DB inside the function

$DB = new DBInterface;
function doSomething() {
$DB-doSomethingElse();
}
Then it will not work unless you either pass $DB to doSomething(), or
declare $DB as a global at the start of the function. Like this:
function doSomething() {
global $DB;
$DB-doSomethingElse();
}
Or access $DB through the globals superglobal. RTFM.

The code I just showed you is supposed to do the following, the

$mac3 is the only var that should not be thrown into the fix_mac()
function which is working correctly. The problem is when $mac1 and
$mac2 get put into the fix_mac() function nothing is being returned.
I am not recieving any error codes, just an empty var.
Sample output:
00aa11bb22cc converted to
00-aa-11-bb-22-cc converted to
00:aa:11:bb:22:cc is valid.
As you can see $mac3 is a valid example of a h/w address where $mac1
$mac2 were returned from the fix_mac() function as an empty string.
OK, thanks for that. I've rewritten your function below in much cleaner
code. Some of the situations you've used regexps in, string functions
would work fine. They're also much faster.
The below function works fine in my testing. I removed the special-case
for a valid MAC address at the start since your regexp was throwing
errors and there was no need since you already checked if it was valid
with chk_mac() (which by the way should return true or false, not 1 or
0, but meh).
?php
function fix_mac( $mac ) {
if( eregi(
^[0-9A-Fa-f]{2}\- .

It looks fine to me, but you might like to try accumulating the records
say up to 100 at a time and then doing extended INSERTs (if your MySQL
version supports them) like this:
INSERT INTO tablename
(col1, col2)
VALUES
('value1', 'value2'),
('value3', 'value4'),
('value5', 'value6'),
('value7', 'value7')
... and so on.
These are apparently much nicer for MySQL to process, which may result
in lower memory usage and faster operation.

$Blah, cannot be larger than 2147483647, and sometimes, I get negative
integers back from the above function.
This is with PHP 4.4.0 on FreeBSD 5.4-STABLE. Can anyone else perhaps
confirm this, and if it is indeed true, is this a bug, or a limitation
somewhere on PHP? Any other ways to confirm that *large* numbers, are
indeed integers? I'm working with numbers in the form of mmddsss
(20051025001 for today for example)
It's not a PHP bug. I'm guessing you're on a 32-bit platform. 2147483647
is the maximum length of a signed integer on a 32-bit platform, and PHP
doesn't do unsigned integers.
A date in the form of mmddsss etc. isn't really a number, so if it
was me I'd probably treat it as a string. If you really *have* to treat
it as a number, then use float and get all the precision errors that
come with floating-point, or use binary coded decimal or another
arbitrary precision system.

I've already warned them that a PDF embedded into a page is impossible. That may not be true, technically, for all I know, but I've sure never seen it, and don't even want to try to go somewhere that so few have gone. I would expect that putting the PDF in an iframe would work, but I wouldn't trust browsers or the Acrobat plugin to not crash horribly in that sort of situation. It's also going to be very confusing for users seeing the Acrobat toolbar floating in the middle of their page. It would be interesting to see some tests of PDF-in-iframe done in various different browsers, but unless it just happened to work perfectly in every common browser (we can all dream, can't we?)

So I'm reading up on character encoding in XML documents as I think
this is the problem (after the many helpful suggestions on this list).
With regards to your second question; no, I'm not sure if I'm using
proper utf-8 througout the entire process. When I input from the form
I'm converting everything via htmlentities . This is why I'm getting
egrave; etc... (On a side note, is there a function or way to check to
see if a form is using the native characters (from a copy and paste of
a word document like è) or the HTML entity egrave; .
If you're using the correct character set all the way through, you only
need to do htmlspecialchars() to convert things like amp; and lt;, as
all the other characters should already be present in the character set
you are using (UTF-8). htmlentities() is mostly used for converting
characters outside of your character set into entities.
I've changed the content-type from text/xml to application/xml but that
doesn't seem to help.
As only UTF-8 and UTF-16 have to be supported, I'm concerned whether
the processor might think it is some other encoding.
The HTTP headers are:
Date = Sat, 15 Oct 2005 17:49:02 GMT
Server = Apache/1.3.33 (Unix) mod_jk/1.2.8 PHP/5.0.4
mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4
FrontPage/5.0.2.2635 mod_ssl/2.8.22 OpenSSL/0.9.7a
X-Powered-By = PHP/5.0.4
Cache-Control = no-cache
Connection = close
Content-Type = application/xml
header('Content-Type: text/xml; charset=UTF-8');
I guess pursuant to cc's suggestion, I should do an html_entity_decode
when I make the xml document and then do another htmlentities on the
html representatoin.
Shouldn't be any need. Characters like è don't have any special meaning
in XML, and they can be represented in the UTF-8 character set, so
there's no need to convert them to entities at any stage.

Everything works as long as $row['LITERATURE_title'] is one word, see

same thing happens.
If you've got a row ID number or something, just call the form lit[id]
(replacing [id] with the ID number), because I don't think a form name
can start with a number. Otherwise you could sha1() the title and use
that as the identifier, or simply remove all spaces...

Don't create a table for every song Have a `songs` table containing all of the songs. Something like: CREATE TABLE songs (songID INT UNSIGNED NOT NULL AUTO_INCREMENT, artist VARCHAR(50) NOT NULL, title VARCHAR(50) NOT NULL, PRIMARY KEY(songID)); (simplified) and another table `comments` like this: CREATE TABLE comments (commentID INT UNSIGNED NOT NULL AUTO_INCREMENT, songID INT UNSIGNED NOT NULL, comment TEXT NOT NULL, PRIMARY KEY(commentID), KEY(songID)); and another `ratings` like this: CREATE TABLE ratings (ratingID INT UNSIGNED NOT NULL AUTO_INCREMENT, songID INT UNSIGNED NOT NULL, rating TINYINT UNSIGNED NOT NULL, PRIMARY KEY(ratingID), KEY(songID)); That's why it's called a *relational* database. If you're using InnoDB you can even define the relations between the tables using foreign keys. Go to http://dev.mysql.com/doc/en/mysql/ and have a good read of the MySQL manual, it will be very helpful for you.
