Hi,
Brand new to regex. So I have a cli which runs a regex on users input,

Windows; I have not yet tested this on linux, and I will, but I would
like this to be compatible with both OS's) it loops infinitely saying
invalid data (because of the next method call, which decides what to
do
based on your input). So, here is the input code. Is there a way I can
ensure that control commands are stripped, here?
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:
/[\x00-\x1f]+/
public function getSelection() {
$choice =
$this-validateChoice(trim(strtoupper(fgets(STDIN;
return $choice;
}
private function validateChoice($choice) {
$choice =
ereg_replace(/[^0-9A-Z]/,,$choice);
return $choice;
}
I have tried a ton of different things to try and fix this. Tried
/\c.|[^0-9A-Z]/, and many variations of \c and the [^0-9A-Z], to no
avail. I also tried using both preg_replace() as well as
ereg_replace().
I spent a lot of time on the regex section of the PHP manual, but I am
not finding anything. Any advise on how to accomplish this?

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:

[0] = Array

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.

RE: [PHP] flushing AJAX scripts
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.

Sad to say, same result. The second option looped an error: Warning: preg_replace(): Compilation failed: nothing to repeat at offset 17 The actual value is 0x1A, and it maps to the ASCII SUB (substitute) control character. The carrot-Z (^Z) representation is how Unix CLI software would display it. Many control codes that didn't actually do anything were printed on the terminals with the carrot prefix. Sometimes codes that did trigger a function in the terminal would be printed that way to prevent the function from triggering. Control-Z is a left over from the CP/M days. It was used to mark the end of text files, since the original file allocation table (FAT) only tracked the number of clusters assigned to a file. Some MS-DOS and MS-Windows applications still tack it on to the end of files. I guess that's their idea of backward compatibility.

Thanks, but this regex did not seem to work for me. At least, not on
Windows. I will not be able to test on linux for a few hours.
I spoke too soon yesterday, too. Control-Z is a problem on Windows, and
not on Linux. However, on linux, control-D is a problem.

RE: [PHP] Regex
Bruce,
Sure thing. So basically what I am trying to accomplish is when this
script runs, a menu is displayed to the user, it looks somewhat like
this:
Welcome
To continue, please select your game mode.
[Mode] [Description]
A.) Mode A
B.) Mode B
C.) Mode C
D.) Mode D
E.) Mode E
F.) Mode F
Q.) Quit.
To begin, please type the mode letter.
Mode:
Then, the below lines of code come into play:
public function getSelection() {
$choice =
$this-validateChoice(trim(strtoupper(fgets(STDIN;
return $choice;
}
private function validateChoice($choice) {
$choice = preg_replace(/[\x00-\x1f]+/,,$choice);
return $choice;
}
So now the script is waiting for user input. The next thing to happen,
right after this code, is:
private function validate($choice,$display,$input) {
$valid = false;
while(!$valid) {
switch($choice) {
case Q:
$display-writeCredits();
sleep(4);
exit(0);
case A:
$valid = true;
break;
case B:
$valid = true;
break;
case C:
$valid = true;
break;
case D:
$valid = true;
break;
case E:
$valid = true;
break;
case F:
$valid = true;
break;
default:
$display-writeInvalidChoice();
$choice =
$input-getSelection();
break;
}
}
return $choice;
}
Now, this is where the script loops infinitely. But, this is only the
first method which validates user input. There are several others.
Basically, my script should accept user input, strip anything that will
not be needed (like anything other than letters and numbers) and then
allow the user to proceed, where the script checks to see if the
numbers/letters they entered correspond to the menu's in any way.
Everything in the script runs perfect, except the fact that the control
statements print infinitely. And while I am sure there is something I
could do to this method to make it not loop infinitely, I would also
need to do this to several other loops.
Thanks,
Jesse Hazen

Brand new to regex. So I have a cli which runs a regex on users input,
to make sure that only 0-9 and A-Z are accepted. It should strip
everything else. My problem is that when you press control-Z (on
Windows; I have not yet tested this on linux, and I will, but I would
like this to be compatible with both OS's) it loops infinitely saying
invalid data (because of the next method call, which decides what to
do
based on your input). So, here is the input code. Is there a way I can
ensure that control commands are stripped, here?
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:
/[\x00-\x1f]+/
public function getSelection() {
$choice =
$this-validateChoice(trim(strtoupper(fgets(STDIN;
return $choice;
}
private function validateChoice($choice) {
$choice =
ereg_replace(/[^0-9A-Z]/,,$choice);
return $choice;
}
I have tried a ton of different things to try and fix this. Tried
/\c.|[^0-9A-Z]/, and many variations of \c and the [^0-9A-Z], to no
avail. I also tried using both preg_replace() as well as
ereg_replace().
I spent a lot of time on the regex section of the PHP manual, but I am
not finding anything. Any advise on how to accomplish this?
Thanks,
Jesse Hazen

[PHP] Regex help please
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 = '

{Site.id}
/td

{/$sites}';
And I want to capture the first {$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);

Re: RE: [PHP] flushing AJAX scripts
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? Jim Andrea Giammarchi wrote: 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.

RE: [PHP] flushing AJAX scripts
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.

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

[PHP] validating and sanitizing input string encoding
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?

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.
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;
}

[PHP] SESSION values show up days later!
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!

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?

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.

Session variables (as far as I know) will persist as long as the user keeps open his browser, or until they time out.

Re: RE: [PHP] flushing AJAX scripts
Well, the point was that I had tried the first way, submitting one AJAX request and waiting for it to finish and it was timing out, probably on my firewall which it shouldn't have - but it did. The reports can take 10 seconds or 10 minutes to create. Doing it this way I can still load the report even if the original request shuts down after 3-4 minutes.

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.
