there is, your control-Z is not a Z at all, and it's only printed as ^Z
so you can see it ... it's actually a non-printing char.
try this regexp for stripping control chars:

I'm normally OK with regex, especially if I fiddle with it long enough,
however I have fiddled with this one so long that I'm either totally
missing it or it's something simple. Does it have anything to do with
the backref, or the fact that the value of the backref has a $? I have:
$out = '
{$sites}
<tr>
<td>
{Site.id}
</td>
</tr>
{/$sites}';
And I want to capture the first {$tag}, everything in between and the
last {$/tag}. I have tried several things and here is my current regex
that looks like it should work, but doesn't:
preg_match_all('|{\$([^}]+)}(.+)({/\1})|Us', $out, $matches);
Gives:
Array
(
[0] => Array
(
)
[1] => Array
(
)
[2] => Array
(
)
[3] => Array
(
)
)

Shawn,
First thing I see--your first capture group doesn't include the $, and
so your final capture group will always fail given your current $out
(because it's looking for {/sites} instead of {/$sites}). Also, your
{} are outside of your capture group in \1, but inside in \3. Here's
what I came up with:
$out = '
{$sites}
<tr>
<td>
{Site.id}
</td>
</tr>
{/$sites}';
$matches = array();
preg_match_all('#{(\$[^}]+)}(.*?){(/\1)}#s', $out, $matches);
print_r($matches);
Produces this:
Array
(
[0] => Array
(
[0] => {$sites}
<tr>
<td>
{Site.id}
</td>
</tr>
{/$sites}
)
[1] => Array
(
[0] => $sites
)
[2] => Array
(
[0] =>
<tr>
<td>
{Site.id}
</td>
</tr>
)
[3] => Array
(
[0] => /$sites
)
)
Keep in mind, I had to view the page source in order to see the HTML
tags, but it showed me everything I expected to see.

Yes, thank you. I was fiddling before I got your post and I came up
with roughly the same.
preg_match_all('|{(\$[^}]+)}(.+){(/\1)}|Us', $out, $matches);

My page submits the AJAX request to complete a report that takes some
time, and upon completion stores results in a database. A second AJAX
request polls every 5 seconds and queries the database if the report is
ready. This hopefully will get around any timeout problems I am having
with a long running request, and seems to be working. It looks like I
can accept the default behavior for now. I don't depend on getting a
response from the original request, but is there a point where the AJAX
response script will be stopped either by Apache or PHP before it can
insert into the database?

Some browser would like to receive at list N characters (bytes) even if
you force the flush, before the browser will show those characters.
In
any case, the Ajax request will not be completed until its readyState
will be 4, which means the page execution on the server has finished
(released, php has gone, flush or not flush)
For a task like this one you have few options:
1 - launch new thread if your host is able to do it
2 - use a Comet like response (for php I wrote Phico some while ago)
In any case, I hope this stressful operation cannot be performed from thousand
of users or you can say bye bye to the service.
Alternatives:
1 - optimize your database
2 - delegate the job once a time rather than every click (cronjob)
3 - if the bottleneck is PHP, create an extension in C to perform the same task
Hope this help.
Regards
P.S.
Internet Explorer a part, you can read the responseText on readystate 3
which will be called different time (most likely for each flush).
If IE is not your target, you could consider this opportunity to read the sent
stream so far.

Try something like this

Sorry, Kim, but why on earth you are polling with a second request to know when
the first one has finished?
I mean, when the first request inserts data in the database that's it, you'll
manage the end of the request.
$A ---> do stuff; do stuff; do stuff; report ready;
$B ---> report ready?
$B ---> report ready?
$B ---> report ready?
$B ---> report ready?
report ready; ---> notification to A
$B ---> report ready;
the report ready, if it is when $A request has been finished, will be in $A,
the polling via $B is absolutely useless, imo.
There is no timeout from Ajax, it simply keep waiting, but obviously if your
PHP has max_execution_time 30 seconds and the script execution takes more than
30 seconds there's no polling that could save you.
The same if the user closes the browser, connection lost, bye bye response.
To have a notice, you need Comet, try out Phico but still, a page that requires
that much is not suitable for the web. Report creation should be a cronjob in a
separed thread if it is that stressful.

yes.
my conclusion is that 2-param strtr is safe if the subject text and
parameter strings are valid utf-8.

You could have a landing page to the site, that consists of image links
(you could use their photo for this?) and each link is in the order of
page.php?person=mum etc. That would require an extra click, but no
typing for a login, and should make the unique person process a bit more
intuitive.

Hi all.
Newbie here.
I have set up a blog site where my family creates posts and they get emailed to
members of the family. To keep up with their identities, I created a script for
each family member to run (dad.php, mom.php, etc.), and it sets a cookie on
each computer and uses sessions so I know who is connecting. It works great
unless I want to share a computer between two users.
I thought I had a solution: install both Firefox and IE on the same computer
and set two different cookies. But this doesn't seem to work. My question is:
Is it possible to set one cookie for IE and another for Firefox so that,
depending on which browser is used, I can tell who is connecting to the blog?
If this is not possible, is there another easy way to do it?
Thanks for your help.
- Ken Watkins
Why not just use session cookies that expire as soon as a session is
over (browser quits) and use a login?

Hello gang,
I know this is not an fpdf mailing list but if anyone has experience
on the matter please help. I am working on a pdf generation part of a
project and I am using fpdf to generate them.
The content of the pdf needs to be in greek. But I am having
difficulties to get the pdf generated properly. This means that I can't
see the greek in the pdf file that is generated. I have tried to set the
encoding to non-UTF since fpdf doesn't support UTF-8 but the problem
still remains. As a second solution I am trying to add new fonts with
the ISO-8859-7 encoding but it doesn't work as expected. The font is not
being although I am following the fpdf's directions step-by-step.
Does anybody know another way to generate pdf files with greek properly
or can help me with the fpdf??
Thanks in advance.

The site is under maintenance. You could wait or download it from:

Note that I do not know of the validity of that site so have your

The php script language has no bearing on the output unless you have
characters In the php file itself.
We had some issue like this at work. They found a way using iconv to
to it but had to change because redhats iconv isn't updated. They do
something with saving the output to a utf8 encoded page and then
sending it out or something. I assume you're trying to have this be
used in excel?

file. I am
outputing html tables with the Content Type set to msexcel.
The chinese texts came out as symbols. I tried
using mb_convert_encoding the text from UTF-8 to UTF-16LE
iconv from UTF8 to gb2312
iconv from UTF-8 to cp1252
Can anyone who has successfully export english text with chinese
characters
mixed in to CSV help?
Thank you very much,
Ai Leen
Strictly speaking, a csv file won't contain HTML markup, so you should
probably just stick to delimited value lines in your file. Have you
tried changing the Content Type to text/plain and then save your PHP
script as utf-8. It's this last one that sometimes causes problems,
as I
believe it is needed for PHP to correctly output utf-8.

I do have a bit of a problem which has not been clearly explained in
the suggestions to my previous posts and that is the question of
hierarchies. I have not yet understood how to include a file anywhere in
a directory tree and have it point to the right file which may be in the
top directory or, most likely, in a /lib/ directory from the file that
is including.
Any suggestions, or should I just make myself small and
wait for the rotten eggs and spoiled tomatoes to come raining down on my
head? :'(

Are you talking about having a file structure such as:
/home
/include
/webroot
/->images
/->css
/->java
And you want to include a file from the include folder which is above
the webroot, so doesn't have access to it?
If that's the case... you just need to set the path such as:
ini_set("include_path", "/home/include");
then in your PHP file you should be able to: include("mysupperfile.php");
and it should work :)

Not quite, but interesting option. This would be fine on my local
intranet, if needed; but I don't think this would be allowed on a
virtual hosted site.
Actually, my problem is to use a header.php (for example) in pages in
the webroot directory or any directory within (or under) webroot:
/ <---- webroot
/site1
/files
/images
/lib
/more files
/admin
/other_files
/still_others
/site2
/site3
files
files
files...
I have the header.php file in /lib .
If I put include dirname(_FILE_)."/lib/header.php"; in a file under
/site1, the header is displayed.
If I put the same include statement in a file under /site1/files, the
header is not displayed; if I change the include to
..."/../lib/header.php"; it then works.
I want to be able to point to the include to the same file in the same
directory without having to change the include directive.

I actually use that on a shared host... Really depends on the host
though... My actual file path is something more like:
/home/
/myusername/
/include/
/public_html/ <---- Web root
/file.php
/another folder/
So all my files are inside my home folder on the server, but nothing
outside of public_html is accessible from the web.
As for the rest... I haven't started using dir(__FILE__) stuff yet so I
won't be any help with that...

The problem is with how you are organizing your app. Includes are
relative to the first file that's loaded, so if the first file that is
loaded is in /site1/files/ then you have to know where /lib/header.php
is from there.
Most people don't load individual files (at least not from different
dirs) as you seem to be doing. My advice is to always load the same
file first from the root dir and then include your other files. Then
those files will include header.php relative to the root dir.
*** Example:
(/site1/index.php)
<?php
//based upon some criteria
include('files/yourfile.php');
?>
(/site1/files/yourfile.php)
<?php
include('lib/header.php');
?>
*** Better Example:
(/site1/index.php)
<?php
include('lib/header.php');
//based upon some criteria
include('files/yourfile.php');
?>
(/site1/files/yourfile.php)
<?php
//content that is original to this file
?>
Above when I say "based upon some criteria", it would be something like
this (example only):
switch ($_GET['file']) {
case 'yourfile':
include('files/yourfile.php');
break;
case 'somefile':
include('more_files/somefile.php');
break;
}

Hi,
I am trying the following code to generate a pdf:
try {
// Create a new pdf handler
$pdf = new PDFlib();
// open new PDF file
if ($pdf->begin_document("", "") == 0) {
die("Error: " . $p->get_errmsg());
}
// Set some info to the new pdf
$pdf->set_info("Creator", "Test");
$pdf->set_info("Author", "Test");
$pdf->set_info("Title", "Test");
// Start the page
$pdf->begin_page_ext(595, 842, "");
// Load the documents font and set the details
$font = $pdf->load_font("Times-Roman", "iso8859-7", "");
$pdf->setfont($font,24.0);
$pdf->set_parameter('autospace',TRUE);
// Set the position inside the document
$pdf->set_text_pos(50, 700);
// Now start to show the data
$str = 'Αυτό είναι ένα τεστ.';
mb_convert_variables('ISO-8859-7','UTF-8',$str);
$pdf->show($str);
// End the page and the document
$pdf->end_page_ext("");
$pdf->end_document("");
// Get the document from the buffer find it's length
$buf = $pdf->get_buffer();
$len = strlen($buf);
// And finally print it out to the browser
header("Content-type: application/pdf");
header("Content-Length: $len");
header("Content-Disposition: inline; filename=hello.pdf");
print $buf;
}
catch (PDFlibException $e) {
die("PDFlib exception occurred in hello sample:\n" .
"[" . $e->get_errnum() . "] " . $e->get_apiname() . ": " .
$e->get_errmsg() . "\n");
}
catch (Exception $e) {
die($e);
}
Although greek are printed normally the characters are overlapping on
each other. The script in encoded in UTF-8.
Does anybody have any suggestions on this? Please any help would be
appreciated.

LaTeX has some greek stuff that works fairly well - though you have to
use one of the fonts encoded for LaTeX.
If you mean to have a web app generate the PDF you'll have to output to
.tex and then use a shell command to compile the document, but it is a
solution that is fairly well tested for creation of Greek (monotonic and
polytonic) PDF documents.
I know that isn't what you asked, but in case there isn't a PDFLib
solution to the typesetting issue, I suspect an application designed for
typesetting will give better results anyway.

the article at http://devlog.info/2008/08/24/php-and-unicode-utf-8, among
other web pages, suggests checking for valid utf-8 string encoding using
(strlen($str) && !preg_match('/^.{1}/us', $str)). however, another article,
http://www.phpwact.org/php/i18n/charsets, says this cannot be trusted. i
work exclusively with mbstring environments so i could use
mb_check_encoding().
which leads to the question of what to do if mb_check_encoding() indicates
bad input?
i don't want to throw the form back to the user because most of my users
will not be able to rectify the input. errors in the data are undesirable,
of course, but in my application, no disastrous. so i'm inclined to the
approach mentioned here:
http://blog.liip.ch/archive/2005/01/24/how-to-get-rid-of-invalid-utf-8-chara
cters.html, i.e. iconv("UTF-8","UTF-8//IGNORE",$t), which will quietly
eliminate badly formed characters and move on (iconv will throw a notice on
bad utf-8).
so i'm considering using a function like this:
function clean_input(&$a) {
if ( is_array($a) && !empty($a) )
foreach ($a as $k => &$v)
clean_input($v);
elseif ( is_string($a) && !mb_check_encoding($a, 'UTF-8'))
$a = iconv('UTF-8', 'UTF-8//IGNORE', $a);
}
and calling it on $_POST or $_GET as appropriate at the stop of any script
that uses those superglobals.
it seems a bit lazy to me but that's my nature and i think this might be
good enough. any thoughts?

Hi all,
I use session variables to store values from one page to another on
my website.
Alas, sometimes, but not always, the values persist from one
invocation of the script to another!
Just how, exactly, do I make them go away when a user exits the
program? I assume my users will not always be logging out explicitly.
Thanks.

if this is on a server with low traffic, e.g. a development or test server,
it could be because of the way the garbage collector works. it's explained
in the manual.

Unset the variable. Session variables (as far as I know) will persist as
long as the user keeps open his browser, or until they time out. But you
can do unset($_SESSION['myvar']) to unset a particular variable at any
time (assuming you have previously called session_start()).

Ok so, I have an array
[0(index)][1st key][2nd key]
Basically I don't care about the index. As a matter of fact I'd prefer it
reset to still be in order afterwards.
However, I need to sort the 1st key and keep correlation w the second key.
Then sort on the second key.
I have video volumes and scenes like
[0][110][1]
[1][110][3]
[2][110][2]
[3][110][4]
Any help would be much appreciated.
