Hi all. I'm curious as to the performance difference between scripts
that use sendmail vs. smtp for their mailing abilities.

I use the following class for delivering emails,
http://phpmailer.sourceforge.net <http://phpmailer.sourceforge.net/> ,
and since I don't have sendmail running on my local machine I'm using
the smtp server of the university where I work to deliver my messages.
However, it seems to be a bit sluggish.

I'm going to run a test of switching the mail handler from smtp to
sendmail once the application is in its permanent home in a few weeks,
but for now does anyone have any opinions on this, and is there any
advantage to using one over the other?

Thanks in advance,

Pablo

Using sendmail will almost always be very very much faster because

- you're talking to the local machine
- you're offloading the mail process to something else

and so if you can do so -- even if your machine is only set up with a
"dumb" mailer that only knows how to talk to your U's smarthost -- I
would recommend that you run, not walk, to do so :-)

Forget SMTP. There is a myth that SMTP is faster than queuing message
via sendmail but that is just a reflex that some people do not
understand how it works.

What you need to understand is that sending messages usually consists on
two things: queueing and deliverying.

Usually you do not deliver messages directly to the end recipient. You
just pass them to a MTA (Mail Transfer Agent) that will take care of the
delivery.

When you you pass the message to sendmail program, depending on it may
be configured, it may either try to deliver the message immediately and
return when it is done, or just leave the message on the local queue for
later delivery.

When you relay the message to a SMTP server, usually it just queues the
message there for later delivery.

Obviously, if you use sendmail and it tries to deliver the message
immediately, it will take eventually a little more time, but the message
is already delivered. If the message is queued for later delivery, your
PHP script does not have to wait so much but the message may take much
longer to be deliver.

Even if you just want to queue the messages for later delivery to free
your PHP scripts, sendmail can do it much faster because you will be
using local interprogram communication to injec the message in the local
queue. If you do it via SMTP server, you need to establish a TCP
connection which is much slower even when the SMTP server is in the same
machine.

If you just want to free your PHP scripts and leave messages in the
queue, what you may need to do is to pass sendmail the appropriate
switches to tell it to do it so.

For that, you can check sendmail documentation to see the available
modes, or you may want to try this e-mail message composing and sending
class that has sub-classes specialized in delivering via mail()
function, sendmail, qmail and SMTP.

The sendmail subclass provides options that translate to the appropriate
sendmail switches. For faster queueing, set the delivery_mode variable
of the sendmail_message_class to SENDMAIL_DELIVERY_DEFERRED .

If you can have a qmail MTA in your machine, use qmail because it is by
far the most efficient.

Hello PHP-list,

I'm building a script, that provides a honeypot of invalid email
addresses for spambots.. for this I want to provide a macro for the
templates that looks like %rand[x]-[y]%, where [x] and [y] are
integers, that specify the length of the random script.
My first thoughts were about the best parsing of the %rand..%-part,
but now I came to a point, where I could also need suggestions on the
random string generation..
It considers very basic word generations and the only meaningful word
I discovered was 'Java'.. *g

For generation of a random string with length 1.000.000 it takes about
13 seconds on my xp 1600+.. that's quite a lot, imho, so suggestions
are very welcome..

the script goes here, ready to copy'n'paste:

--------------------------------------------------------------

Just so we're clear on this - you're creating a string (an email
address) of a million characters? I don't know my mail RFC's that well, but
I'm sure this is well beyond what it considers "standard".

Does the string HAVE to make sense? I mean does a spambot really
care less, or can even detect, what the email address contains? Surely
just creating a truly random string would suffice (and indeed remove
the need for the rather elaborate function you posted). I fully accept
I might be missing the whole point here :)

I missed the original post, and I'm too lazy to go looking, but the
following code runs in approx. 2.75 seconds on my Athlon 2400 running
linux:

    $chars = '0123456789'
            .'abcdefghijklmnopqrstuvwxyz'
            .'ABCDEFGHIJKLMNOPQRSTUVWXYZ';

$charArray = array();

 for( $i = 0; $i < 1000000; $i++ )
 {
 $charArray[] = $chars[rand( 0, 61 )];
 }

It's runs much faster than using a .= style of string creation.

Cheers,
Rob.

We're not clear.. ;)
the function I've posted is designed for templates, that handle the
output my script generates.. it's useful to have non-email text
portions in between or a short random string for the mailto-links
description..

RD> Does the string HAVE to make sense?

I found it better to follow some rules..
At first that were spaces in between and it got bigger.. if I'd write
a spambot I would check if the page I'm lurking on is a oneliner or
does only contain non-email words with > 20 characters, and so on..

Looks good, I have already something similar as "generate invalid
addresses" in my project, which only needs translation of the config
section and some logging statistics, which are done in MySQL.

At first, I only wanted to do a floodprotection for the notifybyemail
feature, but now I'm with the whole config part into db.. :o)

Anyone who'd like to betatest this, is very welcomed to drop me an
email.

A release post will also go here..

..and replacing "$charArray[] =" with "$s .=" crawls this down to 3.5

If you mean so that the user can click the "department" column heading
and have the data sorted by department, then you can create a link to
the current page with url parameters orderBy and disposition. For
instance:

myPage.php?orderBy=department&disposition=ascending

Then in your page you can check the values of these and modify the
"ORDER BY" clause of your query. The following example exemplifies what
I'm saying:

     $qString =
        "SELECT "
       ." name, "
       ." department "
       ."FROM "
       ." foo_table "
       ."ORDER BY ";

    if( isset( $_GET['orderBy'] )
        &&
        $_GET['orderBy'] == 'department' )
    {
        $qString .= 'department ';
    }
    else
    {
        $qString .= 'name ';
    }

    if( isset( $_GET['disposition'] )
        &&
        $_GET['disposition'] == 'desc' )
    {
        $qString .= 'DESC ';
    }
    else
    {
        $qString .= 'ASC ';
    }

    mysql_query( $qString );

Rob.

Guys,

A problem arised on my application when a user enters a Unicode format code
on the site. Well, we really catch every information and i really need to
get some explanation about it.

ex:

C = U+0108: Latin Capital Letter C With Circumflex

Now this unicode character does not have any keystroke on my computer, i
only have "Character Map (Windows)" to generate this.

On my php form i can type this clearly, but once preview it changes the
character to Í or something similar (I guess).

But when i used a Unicode character that has a keystroke value ë for example
once preview it generates the correct character.

Any bright ideas on this?

Even better, use header('Content-Type: text/html; charset=UTF-8') at the
beginning of your PHP page.

I'm not quite following this and I'm not sure what exactly you're having a
problem with, but I'll try to explain some stuff that it looks like will
help.

Unicode(UTF-8) is a variable multi-byte format. Each character is
represented by 1 to 4 bytes, UTF-8 character number 0x108(264) happens to
require 2 bytes.

So, if anything is trying to read UTF-8 characters with the rules for a
single byte character set you will see the C Circumflex as two separate
characters. UTF-8 should display fine on web page if you set the charset
(like the previous emails incstructed you too) and the users OS supports
UTF-8 (Windows 2000 and XP do, probably the recent flavors of linux as
well).

ISO-8859-1 (Which is the most prevalent character set on the internet) is
single-byte. UTF-8 and ISO-8859-1 do share characters, Every character from
0x00(0) to 0x7f(127) in ISO-8859-1 is a single byte character in UTF-8, with
the same nubmer. So if you are trying to display one of these characters in
the other format, it will appear normal, while all UTF-8 characters
0x80(128) and above will be different and not display correctly.

Are you just trying to store data to be able to retrieve it later?

A block of text submitted to a webform maintains the character set of the
webpage that submitted it (at least in my experience, there may be some
exceptions to this though it is dependant on the browser). So you shouldn't
have any problems displaying the data if the character set on the submitting
page and displaying page are identical.

If a character doesn't fall into a particular character set, there is no way
to store it. UTF-8 is a good catch all because it can handle just about any
character out there.

Plenty of information about Unicode can be found here:
http://www.unicode.org/

I'm working on a page which displays details for a given record, and allows
the user to flip back and forth through a large set of records, much like a
set of index cards. "Previous" and "Next" buttons reload the "card" with the
new record id.

It is important that the URLs for the "cards" be very simple and static
(easily bookmarked), along the lines of: "card.php?id=123".

The complexity comes because there are a number of ways in which one would
want to flip back and forth: by date, by creator, etc. We have a select menu
on the card which provides these options.

If the prev/next buttons and select menu are part of a form, one can check
the menu upon the reload of the page and find the correct new id, but the
page in this case will not have a useful, clean URL. Most likely it will
reference the referring card. We don¹t want that.

What we need is a way of saying "if the menu says date, use this id", etc.

It seemed to me that we might be looking at problem requiring a client-side
solution, but my javascript experiments have been frustrating, and seem to
be veering into browser-conditional waters - one of the great arguments for
server-side scripting.

Still the js approach has been closest to what we need: the php script puts
all the possible links from that card into the page, and then the js
function uses the correct one.

Does anyone have any advice?

Thanks

Let PHP choose the correct one?

Maybe something like this will work:

<a href="foo.php?bar=<? echo $bar; ?>">Click here</a>

Then, you can let PHP choose what the appropriate value of bar should be.
Show us some code, and I'm sure we can give you more specific examples.

The trouble is that the value of $bar is dependent on the value of a select
list. And, as noted in my original post, the hrefs for the pages need to end
up being nice, static URLs which cleanly point to the correct data.

That's not all that different from what I'm doing. The following gets called
from the left arrow graphic:

...

I know next-to-no javascript, so this has all been cobbled together via an
afternoon's research. It appears to be what _should_ work, but it only
behaves in one browser out of six I've tried (Safari).

I'd just as soon ditch the JS, since I don't want to rely on it being
enabled for this site. I just can't think of a server-side approach.

Assuming you mean the double quote marks, and not a blank space, use
the function htmlspecialchars() to convert the double quotes into PHP
and SQL friendly HTML entities.

disappears.

<html>

<?php
$db = mysql_connect("localhost", "root");

mysql_select_db("mydb",$db);

if ($submit) {

// here if no ID then adding else we're editing

if ($id) {

$sql = "UPDATE employees SET first='$first',last='$last' WHERE id=$id";

} else {

$sql = "INSERT INTO employees (first,last) VALUES ('$first','$last')";

}

// run SQL against the DB

$result = mysql_query($sql);

echo "Record updated/edited!";

} elseif ($delete) {

// delete a record

$sql = "DELETE FROM employees WHERE id=$id";

$result = mysql_query($sql);

echo "$sql Record deleted!";

} else {

// this part happens if we don't press submit

if (!$id) {

// print the list if there is not editing

$result = mysql_query("SELECT * FROM employees",$db);

while ($myrow = mysql_fetch_array($result)) {

printf("<ahref=\"%s?id=%s\">%s- V - %s......</a>\n", $PHP_SELF,
$myrow["id"], $myrow["first"],$myrow["last"]);

printf("<a href=\"%s?id=%s&delete=yes\">(DELETE)</a> ", $PHP_SELF,
$myrow["id"]);

}

<?php

if ($id) {

<input type=hidden name="id" value="<?php echo $id ?>">
<?php

}

?>
 Team A:<input type="Text" name="first" value="<?php echo $first?>">
 
 Team B:<input type="Text" name="last" value="<?php echo $last ?>">

</form>

<?php

}

?>
</body>

The problem is that you're only printing the list if there has been no
editing of the database, when in actual fact you want to print the
list regardless.

Why not just remove this part?

// this part happens if we don't press submit
if (!$id) {

Once again, I have a new version of my DHCP web page. The major fix in this
one is that it does an "nmap -v -p 80 192.168.1.0/24" (thanks to Mike Klinke
for the idea) to re-populate the "arp -n". The old version of my program
would not always show ALL devices on the network. Some would also show up as
"incomplete". I have removed all incomplete ones for this version, but you
could simply comment out the line to put them back if you want them. You can
specify the server's IP manually (as in the case of dual NIC cards), or let
the script figure it out for you.

umm... It all looks good except this one :

function foo::f ()

This is where you get the T_ error. Dont know what you are
trying to do here, but thats the error anyways, :)

Your first example is all correct,

    // myclass.inc.php
    class foo
    {
        // constructor and destructor
        function f () {}
    }

Dont know if it helps you though.

Doesn't work at all…

The code

// Prepare the content of the xml-file to go to the xsl-parser
$xml = str_replace("?", chr(63), $contents);
$xml = str_replace("<empty/>", $kurt, $xml);
$xml = trim($xml);
$xml = utf8_encode($xml);
echo $xml;
makes the string

"<?xml version="1.0" encoding="utf-8"?>"

become

"ï»¿<?xml version="1.0" encoding="utf-8"?>"

And the crap in fron of the string, which seems to come from nowhere,
makes the parser complain about not well formed markup in the
xml-source…

Hi all:

Having some doubts with sql select queries here :

Right now, I have a "student" and a "withdraw" tables.
For example, when student "John" has withdrawn, his name will be inserted
into "withdraw" table but John's record will be kept in "student" table for a
period of 30 days before it is deleted from "student" table. In the meantime,
in "student" table, the status for John should be set to "0" (inactive).
Wonder the solutions I have mentioned is possible? And if so, how shld i go
about doing it ??....Hope to get some help really soon...Thanks in advance!

Hallo People,

I have one problem with creating images on-fly.

Therefore I created 2 files:

1. resize_image.php with the following

<?php

if (!$max_width)

$max_width = 150;

if (!$max_height)

$max_height = 100;

$size = GetImageSize($image);

$width = $size[0];

$height = $size[1];

$x_ratio = $max_width / $width;

$y_ratio = $max_height / $height;

if ( ($width <= $max_width) && ($height <= $max_height) ) {

$tn_width = $width;

$tn_height = $height;

}

else if (($x_ratio * $height) < $max_height) {

$tn_height = ceil($x_ratio * $height);

$tn_width = $max_width;

}

else {

$tn_width = ceil($y_ratio * $width);

$tn_height = $max_height;

}

$src = ImageCreateFromJpeg($image);

$dst = ImageCreate($tn_width,$tn_height);

ImageCopyResized($dst, $src, 0, 0, 0, 0,

$tn_width,$tn_height,$width,$height);

header("Content-type: image/jpeg");

ImageJpeg($dst, null, -1);

ImageDestroy($src);

ImageDestroy($dst);

AND

2. filex.php .In that file i read from database where the image is stored en

then i show small images(thumbnails).

thet part of the code is :

<?php do { ?>

<tr>

<td width="156" height="32" valign="top"><?php echo

$row_rsSubGroup['name']; ?></td>

<td colspan="2" valign="top"><?php

$fotolink="../dbtest/".$row_rsSubGroup['image_1']);

echo "<IMG

SRC=\"resize_image.php?image=$fotolink\">";

</td>

</tr>

<?php } while ($row_rsSubGroup = mysql_fetch_assoc($rsSubGroup)); ?>

This doesn't WORK. Please HELP.
