Because Microsoft engineers are incapable of reading and following a
spec correctly, you will have to supply a "path" along with that
time-out.  The best default path to use is "/"

You can have no time-out and no path, or both, but not just time-out.

For REAL browsers, you should send the content-type with a charset in
the headers as well.

Only something goofy like IE is going to ignore the headers and look
at a META tag instead.

Again, MS doesn't follow specs.  Surprise.

To be super-pedantic, it's also probably better to use:

so the tag closes itself in the new-school XHTML CSS blah blah blah
buzzword way.

Errr.

localhost is going to end up being THEIR localhost, which is, like,
their own computer where the browser is, which is very very very
unlikely to have your moviesite.php script on it, if you see what I
mean...

Unless YOU are running this on your own desktop or something.

And even then, you probably should use $_SERVER['PHP_SELF'] or
something instead of localhost, because if you move this script to a
freshly-installed Windows box, they don't actually set up localhost as
127.0.0.1 in some versions of Windows -- You have to dig around in
god-knows-which-directory to find the hosts.sam file (.sam is for
sample) and then copy it and edit it and then re-boot (cuz it's
Windows) to get localhost defined.

Did I mention that MS engineers don't follow specs?

Well, you WANT it to point to that page, but it probably doesn't, as
noted above...

You kinda need the function call here with () and everything.

Otherwise, what happens is:
#1. PHP "sees" an undefined constant, and assumes you meant:
'session_start';

#2. PHP issues an E_NOTICE error, but your default error_reporting in
php.ini is probably set to E_ALL ~ E_NOTICE which is *BAD* but there
it is, the old default.

#3. So this statement turns into a rather goofy non-operational
statement that does NOTHING but is, in fact, accepted as a valid PHP
staement, for reasons beyond my ken:
'session_start';
is valid syntax.
God only knows *WHY* it's valid, mind, but it's valid.

Also, you should realize that your setcookie isn't really doing much
but send an extra cookie to the browser, which will ANNOY those of us
who monitor cookies before accepting them -- It's just as easy to
store $_SESSION['username'] and use that instead, relying on the PHP
Cookie for the session to work for you, instead of managing your own
Cookie on top of the PHP session cookie.

For homework, you have to change your php.ini file from E_ALL ~
E_NOTICE to just plain E_ALL :-)

You'll be better off in the long run, even if it seems picuyane in the
short run.

While it's remotely possible somebody here uses WikiMedia and knows
the answer it's not really a "General PHP" type of question...

Your best options are:

Ask the WikiMedia folks.

Install LiveHTTPHeaders in Firefox and see what Cookies you get.

Configure your browser to prompt you for all Cookies and see what
Cookies you get.

Depends where your content is coming from.

If it's coming from a database, simply don't include the fields you

[PHP] Extensions Directory (PEAR/PECL)

[Robert Samuel White]

Please let me know if this would be more appropriate to post in a PEAR or
PECL forum.  Today, I've been trying to install some extensions - in
particular, the GD library and the ZIP library.  I've finally managed to get
it all working, but there was one issue that I'd like to clear up for future
reference if possible.

When I ran the command:

pecl install zip-1.3.1

It intalled the zip.so file to:

/usr/local/lib/php/extensions/no-debug-non-zts-20050922/zip.so

The only way I could get zip support working was to put it here:

/usr/local/php/ext

Which is where my extensions directory is located.

I've checked, and the extensions directory is set correctly in the php.ini
file.

Does anyone know where/how it would come up with this other path?

TIA

Hi All,

I have this code,

Short answer... change the value of error_reporting in php.ini to not
report notices. I'm guessing the script isn't working because it's
outputting the errors, in which case doing this should fix it.

Long answer... ignoring notices leads to sloppy coding and should be
avoided where possible. If I were you and I had the opportunity I'd drop
this OSS package in favour of something where the developers do not cut
corners.

I see no reason why the trouble would lie with php.ini.

I'll bet it has something to do with undefined variables.

But these are merely notices, not errors, so they don't explain why 
you never get to the bottom of the program.

Stut and Richard make a good point that these notices shouldn't be 
taking place, but I don't believe they would cause your program to err 
out (although you *are* using a strange OS, so I could be wrong).


Try to catch your mysql errors (as I've sid before) and throw in a few 
debug displays to narrow it down.

addslashes should be changed to http://php.net/mysql_real_escape_string

but that won't solve your problem.

Could you PLEASE tell us exactly what is in $_POST["notes"] other than
something with a quote?

Could you PLEASE use mysql_error() to give us the exact error message?

And, just for fun, print out the EXACT query after all that mess of
quotes is done?

For that matter, you're making life really difficult with the
double-quote thing...

$query = "INSERT INTO Books(...) VALUES('$CLEAN[copyrightyear]',
'$CLEAN[covertype]', ...)";

This presumes that you have scrubbed $_POST data into $CLEAN like you
should also be doing.

You could use $_POST in place of $CLEAN if you don't care about SQL
injection attacks...

E.

Since those probably ARE the correct characters, maybe you ought to
leave them alone, and use a UTF-8 as your charset in your HTML doctype
and headers and a META tag so that they display correctly in a
browser.

If they are just total garbage charactes from, say, MS Word
copy&paste, read the User Contrib notes here:
http://php.net/str_replace for three different solutions.

You may also want to look at iconv, utf8_decode and similar PHP
functions as a last resort if you really really want to throw away the
correct characters and use ASCII characters that are not really
equivalent, but us Americans like to pretend they are. :-)

It depends on the application.

For something with many reads and fewer writes like a forum or basic,
if busy, e-commerce you'd consider setting up MySQL replication with
one master for WRITE operations and multiple slaves for SELECT
operations.

For something with a high write/read ratio such as eBay, that would be
a wildly-unsuitable solution.

Your best bet is to ask the MySQL folks, honestly, since it's unlikely
that anything in PHP is going to be "the answer" to this one.

If you have RAM to spare, you could:
Configure /etc/my.cnf to have N + X connections
Use http://php.net/mysql_pconnect

N would be the number of Apache Max children

X would be a "few" spare connections so that, if, say, you NEED to use
shell 'mysql' monitor to DO something, the fact that ALL N connections
are taken by Apache, won't lock you out.

There are significant RAM issues with pconnect, as well as some bugs
in various versions of PHP/MySQL that make this answer a no-go.  Tread
carefully.

But it's at least an on-topic answer, even if an incomplete and maybe
downright bad answer.

Yes...

But suppose tomorrow you copy that perfectly wonderful script to let
your family upload their "pictures" and you put them in /pictures with
a couple quick changes in the script, because you don't want their
vacation shots mingled in with your web /images

Now, are you going to 100% for sure remember to change the Directory
/pictures as well?  I *know* I would not remember to do that.

Security only really works when it's repeatable, maintainable, and so
damned easy that it's more work to NOT do it than it is TO do it.

I'd rather assume that PHP newbies will write any damn code that
works, and not worry about picuyane things like the extension on an
image, because they don't know any better.

I believe I'm being more realistic that way. :-)

0777 is what you told us for the DIRECTORY containing the file, not
the file itself.

You did not tell use which user/group owned the file, nor directory,
nor which user PHP is running as.

We CANNOT answer your question directly, because you've asked your
question rather badly.

Posting abusive/argumentative replies to those at least trying to help
you is not likely to make things better, is it?

You're on the horse, and can't get the gate open.

We're leading the horse to water, and can't make him drink.

Maybe you can't get the gate open because you SHOULDN'T ride the horse

If $url is an actual URL to the file, with http:// in the front, you

You have to chmod it as a FILE in the file-system.

In Apache with PHP as a Module, it's the User directive in httpd.conf

With CGI, it's that same user, unless it's with suExec, then it could
be anybody, unless...

In IIS, it's probably E_MACHINE_USERNAME user -- but you're on your
own for that one.

The EASIEST way to find out, however, is  which will

except to say that PHP runs as a specific user, and that user can ONLY
change the files it is allowed to change, and that is a GOOD THING.

You should be able to Google for a "Linux filesystem permissions
how-to" and get what you want here.

If you are trying to chmod() the file that is in /tmp from the $_FILES
array, you probably can't do that -- but after you
move_uploaded_file() you should be able to chmod that...  Works for
me.

You may need to play with the directory to which the files are moving
and you may want to do:

$old = umask(0);
move_uploaded_file(...);
umask($old);

http://php.net/umask

Also research what current owner/group and permissions are on the file
to see how you got into this problem to start with.

You could combine up to 32 bits into a 32-bit integer, and store the
choices as an 'int'

Something like:


For nicer syntax, you could use those >> and << operators for
bit-shifting instead of that goofy "2 *" I used, because I was too
lazy to RTFM to lookup the syntax for << and >>

But since you are right on the edge of needing over 32 bits, this is
probably not such a good idea...

You could also just use a string with the same basic framework:

$data = '';
foreach (...){
  if (isset(...)){
$data .= '1';
  }
  else{
$data .= '0';
  }
}

This is not real flexible when you add more choices, however.

Probably the CORRECT way to do it is to store the values in another
table, with an id field back to the current table.

This will provide the most flexibility in the long run, and probably
be more maintainable and have clearer code.

You could claim that your error_reporting including E_NOTICE is the

You're likely to have problems when the user "reloads" (refreshes)
their page -- as well as all sorts of other problems with
forward/backward buttons.

In that case, what you REALLY need is the URL to be random, and the
same picture file to always be returned (for the picture you want).

See below.

It's way worse than that...

This presumably dumps out some HTML, which the user does not even get
for a long time, much less the browser ask for the image, so...

> //deletefile("pictures/products/1_$ran.gif");

Yes, this is WAY too early to delete the file.

> }

Try this:


showpicture("pictures/products/$fileName.gif?$ran", $dbProductName1,
300, 150)

The browser will "see" the ?$ran there and HAVE to get a "new" image
URL, even though it's really the same damn picture.

You may want to look into the many many many archived posts from me
that discus PATH_INFO which describe how to get the ?$ran into the
middle part of the URL, so the URL *looks* like a static directory,
even when it's really a dynamic PHP script.  This will default stupid
browser bugs from ancient browsers, and any similar bugs that crop up
in the future browsers.

You really would need to discuss this at length on a MySQL forum/list,
but basically, the first thing you have to look at is the indeces, if
any, on the tables in question.

If you have an index, it could be a B-tree, or a hash, or any other
number of low-level indexed structures which more-or-less imply the
algorithm to be used in a search/sort.

The second thing to examine is MySQL's estimate of the number and
distribution of records to be loaded/examined/returned.

If the result set to be loaded/examine/returned is relatively high
number and widely distributed over hard drive "pages" then MySQL
"knows" it has to do a full table scan anyway, and goes ahead and does
that, I think.

All of the above is a gross over-simplification of something that
MySQL has put a zillion man-hours into solving -- which is why a
database is so GOOD at this sort of thing.

Of course, one doesn't always have a choice...

For example, one might be faced with a dog-slow crappy Google adwords
API feed that can only return keyword traffic estimates for specific
bids, and then one would be forced to hit that dog-slow crappy Google
adwords API feed in a binary search algorithm just to have any hope at
all of completing one's task in some reasonable time-frame...  Not
that I've ever faced this problem, oh no. :-(

To me, the added complexity of a class to handle something as simple
as binary search, hash-search, or even a B-tree or order N, is just
overhead and complexity of integration that I don't need.

When I need that kind of algorithm, I do not find it difficult nor
tedious to just code it from scratch.

But I can see where others would find it a real boon, so I suspect it
would be quite useful for many to find in PEAR or some reasonable PHP
code library.

What might be MORE useful, perhaps, would be an extension in C to add
some of these algorithms to the language somehow -- Since that would
maybe include a performance boost in the algorithm itself, assuming
you could get the data/structures into and out of the C code in some
reasonable way.

YMMV

Assuming for the sake of argument that your visitor is on an IPv6
machine somewhere, would you want $_SERVER['REMOTE_ADDR'] to be not
set at all, or NULL or ???

For now, at least, you should filter the input and discard ipv6 data.

For that matter, you probably ought to be filtering that input anyway,
just in case, for better security and sql-injections, no?

Hard to see how somebody could push something through that variable to
do an sql-injection attack, but there it is.

Indeed but you specify that you reshow the form and then redirect...

Re: [PHP] Sparse 1.0b - framework for MySQL programs

[Daniel Orner]

	Well... okay, I'll be honest, I never really *wanted* to install it. 
8-) And I'm not exactly a server guru (even updating PHP4 proved to be 
too much for me... for some reason a bunch of dependencies which were 
fine when I got the server no longer work).


er why not? just install a second copy of php into a custom (e.g. your 
homedir)
dir and use that - check the archives for Rasmus' quick guide to setting 
up a second

apache/php installation.

possible reason number 1: XML handling in php5 is rather different than 
in php4,

they offer different xml tools - chances are the exntesion you use

possible reason number 1-N: objects work differently in php5.


	Well, I don't use objects too extensively... I took a look at the 
migrating from PHP4 to PHP5 page on the manual and there didn't seem to 
be anything that would have messed it up. I wasn't aware of the XML 
differences, so yes, that may be a problem. I won't know until someone 
tries. 8-)

How do you avoid a "Cannot modify header information - headers already sent

Nicholas,

As long as you haven't outputted anything from your script after the form
post, you can redirect just fine.

Step 3 and Step 4 are two different steps.

You need something like this:


if (isset($_POST["btnSubmit"]))
{

  // validate form

}

if (!$form_passes_validation)
{

  // show form

} else
{

   Header("location: ");

}

I see no reason why the trouble would lie with php.ini.

I'll bet it has something to do with undefined variables.

But these are merely notices, not errors, so they don't explain why you 
never get to the bottom of the program.


Short answer... change the value of error_reporting in php.ini to not 
report notices. I'm guessing the script isn't working because it's 
outputting the errors, in which case doing this should fix it.


Long answer... ignoring notices leads to sloppy coding and should be 
avoided where possible. If I were you and I had the opportunity I'd drop 
this OSS package in favour of something where the developers do not cut 
corners.

The value in that variable is coming from the web server not PHP. I

That's ok PHP5 is a fringe community *lol*. Although I may switch now
that you can use the var keyword again for class vars.

Then again maybe I should just wait for PHP6 for a full embrace *grin*.
All I know is I don't really need any of the sugar candy in PHP5.

Rob.

Robert,

I do the three first items but not the last one (#3 is done both client-side
and server-side by the way). I can add a hard redirect but I am a bit
surprised that it should fix the issue.

Yet I see it in Chris Shiflett's article at
http://shiflett.org/articles/guru-speak-nov2004

He also advises to add ini_set('session.cache_limiter', 'private');

Can somebody explain the login behind the redirect?

I apologize if this was already posted, but I didn't see it go through.

I'd like to announce the first release of Sparse, a new way to 
create MySQL programs without actually programming anything! Sparse 
takes care of handling the SQL data, navigation, displaying errors, 
input validation, and caching. Using a few extra HTML tags allows 
surprising power, yet remains easy to use and very customizable. It can 
save a lot of time and effort during development! It's especially 
well-suited for creating admin back-ends of sites that use MySQL.
This means that you can actually create entire MySQL-backed programs 
without using a single line of PHP code. However, more complex forms and 
queries can be easily integrated with PHP code as well.


The Sparse homepage is here: http://sparse-php.sourceforge.net/

Besides looking for beta testers, I'd also like to know the best way 
to spread the word about it, so if anyone has any comments or help they 
can offer, please do so!

Re: [PHP] Re: Object Array?

[Jay Paulson]

This keeps getting stranger and stranger.  I did the var_dump and I got this
for R:

  ["R"]=>
  array(10) {

So it's an array but when I pass it through is_array it says it's not an
array.  However, when I pass it through is_object it says it's an object?!

[PHP] Sparse 1.0b - framework for MySQL programs

[Daniel Orner]

I apologize if this was already posted, but I didn't see it go through.

I'd like to announce the first release of Sparse, a new way to 
create MySQL programs without actually programming anything! Sparse 
takes care of handling the SQL data, navigation, displaying errors, 
input validation, and caching. Using a few extra HTML tags allows 
surprising power, yet remains easy to use and very customizable. It can 
save a lot of time and effort during development! It's especially 
well-suited for creating admin back-ends of sites that use MySQL.
This means that you can actually create entire MySQL-backed 
programs without using a single line of PHP code. However, more complex 
forms and queries can be easily integrated with PHP code as well.


The Sparse homepage is here: http://sparse-php.sourceforge.net/

Besides looking for beta testers, I'd also like to know the best 
way to spread the word about it, so if anyone has any comments or help 
they can offer, please do so!

Thanks!

It is on an IIS server.  Any ideas what PHP.ini setting is causing this 
error?

I see no reason why the trouble would lie with php.ini.

I'll bet it has something to do with undefined variables.

But these are merely notices, not errors, so they don't explain why you 
never get to the bottom of the program.


Have you patched statusimage.php yet to report mysql errors? (Display 
your sql statements while you are at it.)


I posted the (GNU open) source here:
http://johnhicks.org/statusimage.phps
in case someone else on the list would care to look.

[PHP] $_SERVER['REMOTE_ADDR'] arriving in IPv6

[Marcus Bointon]

I'm running PHP 5.1.4 on OS X. When I look at $_SERVER 
['REMOTE_ADDR'], it seems to contain an ipv6 address rather than an  
ipv4 one (at present it's giving me 'fe80::1' instead of the usual  
dotted quad), and that confuses the hell out of things like MySQL's  
INET_ATON() function. I have ipv6 networking disabled in my network  
control panel, and my PHP is configured with --disable-ipv6. How can  
I force it to return only ipv4 addresses? Is there an ini setting  
somewhere?


Thanks,

Marcus

[PHP] Re: Object Array?

	Try using var_dump rather than print_r... maybe it'll give you more 
accurate data (e.g. to figure out if it's an object, as Rob said, or an

You are right: $xml->RES->R is an array.

If it doesn't act like an array, you might try assigning it to a new 
variable. Maybe something like this:


$MyArray = $xml->RES->R;
print_r($MyArray);

Others might have better ideas. Keep trying.

[PHP] Object Array?

[Jay Paulson]

I tried with no success yesterday to get an answer to this question so I'll
try again.

I have an object from using simpleXML and inside that object is an array
holding even more objects.  However, it's not acting like an array and
therefore I can't go through it. (i.e. I can't use the count function to see
how big it is and loop through it)

This below should be an array:

$xml->RES->R

When I use print_r($xml->RES->R) I get $xml->RES->R[0] printed, which is
below:

SimpleXMLElement Object

[PHP] Debug/Learn Recursion of an Object

[Graham Anderson]

I am a bit new to Objects and Recursion
Any push in the right direction is appreciated

Generated from Pear's mimedecode, I have an object whose print_r is:
http://www.siren.cc/dev/object.txt


The function below will correctly traverse the object and find the  
'correct' node.

Unfortunately, it is a little beyond my understanding at present. :(

Is there a way to debug the below function to echo how it is  
traversing the object ?
For example, how would I echo the key names  and values while it is  
traversing ?


The hope is that something will click and I'll finally wrap my brain  
around this


many thanks





function getBody(&$part, $primary = 'text', $secondary = 'plain')
{
$body = false;


if (is_array($part)) {

foreach($part as $subpart) {
if (! $body = getBody($subpart, $primary, $secondary)) {
continue;
} else {
return $body;

}
}

} else {

if (isset($part->parts)) {

return getBody($part->parts, $primary, $secondary);

} else {

if ($part->ctype_primary == $primary && $part->ctype_secondary ==  
$secondary) {

return($part->body);
}

}
}
return $body;

[PHP] Re: PHP and mySQL getting smashed...

[Robert Samuel White]

Upgrade your MySQL distribution to the latest version (5+).

 

Upgrade any shared MySQL libraries to the latest distribute.

 

Recompile MySQL with mysqli support.

 

http://php.net/mysqli

 

And use that instead of the regular MySQL functions.

 

That's what I did and it has made a huge difference.

 

Not to mention, the mysqli library has so many more functions available to
you.

[PHP] Re: [Repost] Getting rid of "Web page has expired" (POSTDATA Error)

[Robert Samuel White]

You might want to modify your coding.  The way I prevent this problem from
ever happening is this:

 

1.  The user completes information on the form.

2.  The form is validated by PHP.

3.  If there are errors, then the form is reshown with their values
populated.

4.  Once all errors are corrected, I process the form and then use a
Header("Location: ") to redirect the user to the same page (or another
page).

 

This has the advantage of allowing a user to click the back button and
seeing their form with their values still intact.

 

This prevents a method post page from being in the user's browser history.

Since this is open source code ('phpOnline') available at
http://www.dayanahost.com/phponline.cfm

I guess it's safe to post an excerpt here:

...
[a number of mysql statements without error checking or other exits]
...
[concluding with:]

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

if($LastAdmLoginTime==0 || $LastAdmLoginTime<($TTime-120))
{
   echo implode('', file('pathtooffline.jpg'));
   $OnlineStatus = 0;
}
else
{
   echo implode('', file('pathtoonline.jpg '));
}

Since both of these images are present (i.e. can be accessed
directly)
and since there isn't any exit prior to the execution of the above
statement, I conclude that the program must be erring out before
it gets
here.

Check your php error log first. If you don't find anything there
then
edit the program to add error checking for all the sql commands.

You might also find help at the phpOnline forums:
http://www.dayanahost.com/forum2/index.php?act=SF&f=11&;


If you can't find the problem, since the program is short, you could
post it to the list.

No problem being a dick -- my question was "is psacln the group"?


which is a question about the *nix filesystem - bit off the scope for
this list.

btw 'psacln' is a group created by Plesk Hosting Software installations.
googling for 'psacln' on its own actually would have given you this info
and confirmed that it is indeed a user group.



The answer was "Yes". I was looking for conformation.


confirmation as in confirm not conform.

 That confuses me, because who's the user here? Is it just the system
 administrator or the application?


This is the user that Apache (or whatever webserver) is running as.  If
you're using Apache, look at your httpd.conf file to find out who that
user is.  If you're creating files successfully, you can just look at
the owner of that file to find out who it is.

Is safe_mode enabled?

 >From the manual (http://us3.php.net/chmod):



In my code, I use:

ini_set( 'safe_mode', '0' );

Which I think disables "safe_mode" and from what I've read, the 
default is off and in my phpinfo, it says it's 'off" -- so I think 
it's off. :-)



Note:  When safe mode is enabled, PHP checks whether the files or
directories you are about to operate on have the same UID (owner) as the
script that is being executed. In addition, you cannot set the SUID,
SGID and sticky bits.


I understand that, except for the sticky bits -- I don't know what 
they are, but will look them up later.


But safe_mode is off, so any application should be able to chmod(), right?

However, when my application tries to change permissions via chmod(), 
it fails and generates a warning.


BUT -- considering that this is a permission issue and not a php one, 
as I've been told, I'll end this thread and look elsewhere for an 
answer.

chmod() is working the way it's supposed to.  You're not getting the 
results you desire, and to understand why, you need to understand how 
file ownership and permissions work on a *nix system.

[PHP] LDAP Query

[php]

Our organization is migrating away from Novell E-directory to MS Active 
Directory.  I have a php class that allows me to run various queries on our 
e-directory ldap server which I am working to convert to AD.  However, I'm 
running into an error that i cannot figure out.  I have updated the base_dn to 
point tothe correct location (verified by a third party ldap browser).  Also 
added a username and password since our AD environment doesn't allow anonymous 
queries.  The error I get is 

Warning: ldap_search() [function.ldap-search]: Search: Operations error in 
/var/www/html/intranet/_php/class.ldap_test.php on line 149

On that line I have this line of code
$result = ldap_search($this->conn,$this->base_dn,$filter);

Where $this->conn evaluates to Resource id #3, $this->base_dn is the correct dn 
(ou=something,dc=domain,dc=domain_part_2) and $filter is cn=myusername

Can anyone shed some light on this?  Below is the entire method from the class.

function connectldap($filter,$override=false) {
//connect to the server
$this->conn = ldap_connect($this->server);

//if the connection failed, set the error message
//and return false
if(!$this->conn) {
$this->errMsg[] = "Unable to connect to server\n";
return false;
}
//ldap_set_option($this->conn, LDAP_OPT_PROTOCOL_VERSION, 3);
//bind the connection.  This function will perform an
//anonymous query to get the full 
$bind = @ldap_bind($this->conn,$this->ldap_user,$ldap_passwd);
if(!$bind) {
$this->errMsg[] =  "Unable to bind to server\n";
return false;
}
echo "$filter - " . $this->conn . " - " . $bind . " - " . 
$this->base_dn . "\n";
//run the ldap query
$result = ldap_search($this->conn,$this->base_dn,$filter);
//if the search failed, then return false and set the error 
message
if(!$result) {
$this->errMsg[] =  "Search failed - " . 
ldap_error($this->conn) . "\n";
return false;
}
//get the entries and store them in a variable
$info=ldap_get_entries($this->conn,$result);

//if the number of entries reutnred is zero, then the user
//could not be found in the ldap server
if($info["count"] == 0) {
$this->errMsg[] =  "User Unknown\n";
return false;
}
//otherwise, if the number of entries found is greater than 1, 
then

Hi (please insert your preference):

This should be simple, but I'm having problems.

I have a program that uploads an image file and then tries to set the 
permissions for the image (to be altered later). However, I get a 
"Warning: chmod(): Operation not permitted" error when trying to set 
the permission, what gives? If my program created the file, shouldn't 
it have permission to set the files permissions?


What am I not understanding?


Without seeing code, permissions of the directories, what sticky bits 
might or might not be set, etc., you could not be understanding many 
thingsor just onewho knows.


I read all of your Google links, but no help. Just another example of 
how Google is not the answer.


Then you're asking the wrong question.


In any event, my code is pretty simple, just:

chmod($url, 0755);  //where $url is the file I want to change.

The error I receive is noted above in the subject line.

The permissions of the directories vary, but the folder that has the 
file I want to change permissions is currently set at 0777.


Nice security there.  Regardless, even if the user your webserver is 
running as has write permission to the directory (don't know who 
owns/what group that directory belongs to, as you didn't tell us that), 
you won't be able to change permissions of a file in that directory if 
the file isn't owned by the same user apache is running as.


In doing a lstat() of both the parent program that created the file and 
the child file shows that they both have the identical uid and gid 
(i.e., the same user and group id's).


And what user does Apache run as?


Now, everything I've read, says:

chmod() changes the permission of the specified file with the following 
caveat.


"chmod() can only change the permissions of files that are owned by the 
user running the command. In most cases, this is the user that the web 
server runs on."


That confuses me, because who's the user here? Is it just the system 
administrator or the application?


And if it is just the system administrator, then can't the system admin 
change anything he/she wants anyway? What's the point of having uid and 
gid's if a program can't change the permissions of a sibling file?


This question should answer the previous question for you.

I have tons of references as to what php filesystem functions are 
available, but I need a good reference as to what permissions are and 
how they actually can be changed in php -- does anyone have one a good 
reference OR care to explain?


As it is now, I know how ride the horse, but I can't get the gate open.


File permissions is beyond the scope of this mailing list.  You need to 
buy a book, research on the web, etc., on *nix system administration, 
and concentrate on the filesystem/security/permissions sections, and the 
section on how apps/daemons operate.

They more than likely don't exist because PHP's associative array is
O(lg n) and so everything else is pretty much just as good, except not
quite as good because it will be implemented in PHP whereas the internal
associative array is in C. Additionally PHP already provides all you
could probably need for sorting. If this is purely for academic fun then
I'd say go ahead, but if you are thinking real life applications, then
I'd suggest spending your time on algorithms that don't have a
just-as-good alternative already implemented internally.

BTW, I don't think you can make an O(1) hash table in PHP since even if
you succeeded in making a perfect hash then PHP will perform O(lg n)
lookup into whatever structure you've made.

Cheers,
Rob.

Andrew:

I know what you are talking about, I wrote a splay binary-tree demo, see:

http://www.sperling.com/freeware.php

I've often wondered if there are algorithms like that in php buried somewhere.

However, binary-trees are for searching and I use MySQL for that. I 
don't know specifically how MySQL preforms searches. I had hoped that 
somewhere one could set a bit and change the algorithms, but I 
haven't been able to find any references that allow that.


In any event, the size of the things I work with (<50k items) are so 
small that it really doesn't matter for me -- and I don't know at 
what size where it starts to be a problem for others.


So, if I was to take my previous code and port it over to php, I 
would most certainly test it against MySQL for performance before 
spending too much time providing something that doesn't significantly 
improve the status-quo.

Yes, when I generate my cart I use the itemID as a key field (since the
ID stayed the same but the # in the database could change).

And ALWAYS quote your inputs in HTML.  It makes for a lot less
headaches.  But then I wasn't sending COMPLETE code, just enough to get
him on the right track. :)

We should all be using the guidelines within http://phpsec.org/ to keep
good coding practices.

I too need the screens at 1 dollar (52" Wide-screen format please) as
well as the 6-person hot-tub and deck combo.

sounds like a good idea. probably the reason it doesn't exist is because
the entry level for making something worthwhile is high - and most people
with such needs end up building something specific because it's easier.

if you do go the PEAR route my suggestion would be to avoid all/any of the
PEAR base classes - to save bloat and make the components more usable for
people who don't want/need PEAR (or are not allowed to use it).

that way you can easily fish out the quantities when looping the

Will get you where you need to go on the HTML side of things, then on
the back end you need to process each array.  By setting a default value
of 0 for the qty, you force users to change the values, but you also
keep your arrays intact and easier (IMHO) to deal with.

The tip worked great !! All working as expected now...

$listvals=$_POST['item'];
$n=count($listvals);
$i=0;
while ( $i < $n )  {
if ($qty[$i] > 0) {
AddItem($item[$i], $qty[$i]);
UpdatePrice($item[$i], $price[$i]);
}
$i++;

[PHP] Pictures and caches

Hi!

The thing I want to do is to copy a picturefile to another picturefile.
The thing is that I want to copy this file, show it , and then delete it 
(when it has been shown) .Is this possible?


I want to do this, because of avoiding problems with cache when uploading 
file through an admin-online-system... (the customer uses IE)


When I delete the file in code down below, the picture is not shown (I guess 
because the browser hasn't rendered out all info?)


If you want more code, tell me :-)

Best regards
/Gustav Wiberg



$fileName = "pictures/products/$dbIDProduct1" . "_small";

$ran = strval(mktime()); //Current time

if (file_exists($fileName . ".gif")) {

   copy($fileName . ".gif", "pictures/products/1_$ran.gif");
   showpicture("pictures/products/1_$ran.gif", $dbProductName1, 300, 150,
