[PHP] filling an array(2)

[Steve Buehler]

h.  Ok.  Can somebody explain this one?  Why won't it work correctly?

for($m=1;$m<=5;$m++){
$div_idd[$m]=${'row->sub' . $m . 'd'};
}

Can it not be done with a 3 parter?  The columns in the table that $row 
gets, are sub1d, sub2d, sub3d, sub4d and sub5d.  Or is it the "->" that is 
messing it up?  I have tried escaping them "row\-\>sub", but that didn't work.
What would I search for on the PHP site or where are directions located 
that tells me how to use this type of putting a variable together.  It 
makes it hard to search for it if I don't know what it is called.

Thanks
Steve

Re: [PHP] Help: header function

[Tech Support]

If you have session cookies disabled in your browser then you have to add
the session ID to the redirect. If you have your cookies enabled and you are
still losing the session then there must be some other problem.

no cookie compatible:

header("Location: http://someplace.com/somepage.php?PHPSESSID="; .
session_id() );
exit();

if you have session.use_trans_sid = 1 or you compiled
with --enable-trans-sid the session id will be automatically added to
relative get or post. Both links that are not a relative URI and header
redirects require that you manually append the session id to the query
string to keep the session without the need for a session cookie.

[PHP] including just created file

[Marek Kilimajer]

Hi all,

I just coded a cache mechanism for some slow code that looks like this:

$cache_file_name = "cache/$id/$tid". ($showall ? '_all.php' : 
'.php');
$cache_dir_name= "cache/$id";
   
if(!file_exists($cache_file_name) || 
@filectime($cache_file_name) + 30 < time() ) {
if(!is_dir($cache_dir_name)) {
mkdir($cache_dir_name, 0777);
}
$lock=@fopen($cache_file_name . '.lock','w');
if(flock($lock,LOCK_EX)) {
include('modules/rally_live/create_cache.php');
flock($lock,LOCK_UN);
}
fclose($lock);
}
clearstatcache();
for($i=0;!file_exists($cache_file_name);$i++) {
if($i==3) die('Cannot read cache file!');
clearstatcache();
}
include($cache_file_name);  // *sometimes includes empty file*
echo "";

The 'create_cache.php'  creates a php code, that later needs to be 
executed. The problem is, the just created cache file seems to be empty 
*sometimes* when included, however, if I look at it, it does contain 
code. I do call fflush($cache_file) before closing it, so I don't see 
why the file is empty.
If anyone can help me, I would be really glad.

I never rely on JavaScript existing, much less working correctly for

[PHP] How to UPDATE two MySQL Tables

[Monty]

I have two tables: member_basic and member_detail. When a member edits their
record, they can edit or add data for either table, but, the data stored in
member_detail isn't required, so, they can possibly leave these fields
blank. By the way, both tables would be linked by a member id.

Here's my dilemma: If they do fill in any fields associated with
member_detail, I have to first see whether or not there's an entry in the
member_detail table already for that user (based on member id number). If
not, I then have to check ALL the form fields associated with this table to
see if any data was actually entered so I know whether or not to create a
new record for the member in member_detail. If there is already an entry for
that member in member_detail, then I can just do a standard UPDATE.

Now maybe this is how it has to be done, but, I was hoping there might be an
easier way to do this. It appears it's not possible to UPDATE a JOINed table
during a query, which is what I was hoping. I am trying to keep the DB
efficient by keeping optional data that may be left empty in another table,
but, it's only making my life difficult, so, unless there's an easier way, I
may just combine all the fields into one table and be done with it.

Sorry for the long-winded explanation. Any suggestion are greatly
appreciated!

Monty

RE: [PHP] Close A Databse Connection

[Peter J. Schoenster]

Hi,

The question was about the use of mysql_close. Use it or not (not when to use it or 
when not to). So far:

> Agreed... you should always "clean up after yourself."

> PHP will close the connection automatically will be closed and all
> information cleared.

2 says use it
1 says no.

>From my read of docs I'd say not to use it. I use the Perl DBI with Apache::DBI and 
>it simply overrides the DBI disconnect so calling a disconnect is only a waste of 
>minimal time and typing 
when using it. 

So, in PHP there are also 2 types of connections:

mysql-pconnect
mysql_connect

Well if you are using mysql-pconnect then you would "rarely" use mysql_close() as the 
docs say

Using mysql_close() isn't usually necessary, as non-persistent open links are 
automatically closed at the end of the script's execution. See also freeing resources.
__end quote

Okay, so when, when using a persistent connection would I use mysql_close()? 

http://www.php.net/manual/en/function.mysql-pconnect.php

says

"Second, the connection to the SQL server will not be closed when the execution of the 
script ends. Instead, the link will remain open for future use (mysql_close() will not 
close links 
established by mysql_pconnect())."

See the above url for information from user comments about cutting down idle 
connections.

I think it's safe to say one would not use mysql-close() when using mysql-pconnect, 
although I wonder about the cost of doing that. 

http://www.php.net/manual/en/function.mysql-close.php
says

> Using mysql_close() isn't usually necessary, as non-persistent open
> links are automatically closed at the end of the script's execution.

It seems to me better to err on the side of caution and use mysql_close(). If you are 
using a persistent connection then the call to mysql_close() should be overridden but 
I've got no clue if it's 
done that way. Seems to be related to opening and closing a file. In Perl the file 
will close when the script exits and that's fine for quick stuff but once a script 
begins to grow it allows for bugs. 

I vote to suggest use of mysql_close().

Peter

[PHP] filling an array

Thank You Andrey, Matt and Martin for your answers.  To summarize for 
everyone, here are the answers:

 From Andrey (tested, works):
for($m=1;$m<=5;$m++){
$div_id[$m]=${'divid'.$m};
}

 From Matt:
for($m=1;$m<=5;$m++){
$varName = 'divId' . $m;
$div_id[$m]=${$varName}
}

 From Martin:
for($i =0; $i < 5; $i++) {
$offset = $m + 1;
$divid[$m] = $div_id{$offset};
}

Ye Gods!

I don't think HTTP POST upload is going to be reliable for *that* size
files, no matter *what* you do...

Give them an FTP account or something.

At least FTP can be "continued" (assuming the server/client are configured
properly and current) when they lose their connection after 95MB...

HTTP POST can't be "continued", last I checked...  At least not on most
systems.

Is it possible to pass variables from a form as an array to another PHP

When the form re-loads after being submitted (it calls itself when SUBMIT is

Is it only possible to POST variables to a page if they are not in an array?

[PHP] Close A Databse Connection

[Jay Blanchard]

Well, it's Friday afternoon and the pre-pub run debates have started :^]

The choice of arguement today is born of the fact that I advised a newbie to
always use mysql_close() to close the connection to the database. It's good
form and will cover any ills where the database connection fails to close
for some other reason (say the user stops the page from loading after the
connection is made). I know that it is not required, but always being
competitive I thought I would turn to the group for a concensus, whether I
am right or wrong.

Thoughts?

[PHP] High Resolution Images

[[EMAIL PROTECTED]]

Hello,

I am creating a script that takes an uploaded image, creates a thumbnail
from it, and saves both files.

The script works great, but the problem is, the files It will have to
handle, are high-resolution files (300dpi, 24 bit-depth).. it works fine on
regular files (72 dpi), but when I upload a 300dpi image, it says that the
image is not a valid JPEG file.

Warning: imagecreatefromjpeg:
'/home/sites/site1/web/uploadedHi-Res/mo_0001.jpg' is not a valid JPEG file
in /home/sites/site1/web/site/designers/doSubmit.php on line 6

The image appears to be valid here, it opens on photoshop, and everywhere,
however, once uploaded, the image seems to be corrupted somehow, bc if I
download it again, it won¨t open anywhere. Has this happened to anyone else
on this list?.. if so, please advise!.

Here is the code for the script if it helps:

[PHP] Table formatting

[César Aracena]

Hi all.
 
Last nite I’ve came across a problem I wasn’t able to figure out by my
self. It’s not difficult to make a loop that will make new *TABLE ROWS*
() to show several DB objects in a nice way… what I need to do, is
to display 2 or maybe even 3 of this objects stored in a DB per table
row, separated in different *TABLE COLUMS* ()… how can I achieve
this? What I usually do is:
 
--
// DB QUERY
$query = “SELECT * FROM table_name”;
$result = mysql_query($query) or die(mysql_error());
$num_rows = mysql_num_rows($result);
 
// NOW THE LOOP
for ($i=0; $i<$num_rows; $i++)
{
 $row = mysql_fetch_array($result);
 echo “”;
 echo “”;
 echo $row[whatever];
 echo “”;
 echo “”;
}
--
 
but how can I get 2 or 3 columns displaying different db objects? A loop
inside a loop?
 
Thanks in advance,

Re: [PHP] Re: sessions

[Tyler Durdin]

Still getting the same message. This script used to work perfectly in an 
older version of php. Could it be a problem with how I am setting the 
sessions. Has anything changed with how we code sessions?

[PHP] RE: Paying Job...

[Jason]

I just thought I would share a personal experience that I am currently going
through that relates to this.

I was approached by a client to develop a full e-commerce solution for his
company. I am only one guy, and I had never done any PHP code on this scale
before. I knew this, but I wanted to do the job. So I undercut myself. I
mean really undercut (in hindsight, I shouldn't have undercut myself as much
as I did). I am in the process of delivering a $20,000 - $25,000 website to
this company, and I am only making $2000 on it. I have spent close to 700
hours on the development of this project in my evenings and weekends.

So why did I do it? Three reasons...
1) I wanted the job.
2) I needed a 'good' portfolio piece.
3) I can now buy computer parts cheaper than Future Shop.

If you decide to charge by the project make sure you know what you're
getting yourself into, and that its going to be something you can deliver.
Since I have started working on my project I have gained 3 more contracts
without even trying just by showing them this project.

That and being able to say "I did this... ALL BY MYSELF!" is pretty cool.

Basically, someone is looking to get a database driven site built,

Im looking for advice, as to how the experienced coders in here charge
for their work.
Do you charge by the page, script or by the hour (that would be nice).

You don't have to close it; it's automatic. Just treat $_SESSION like
the regular variable it is. Anything you assign to it will be available
on any page you call session_start(). How much easier can it be??

If you really want a message, then on the last line of your file put 

echo "Session Closed";

Re: [PHP] Installed PHP on home Win98se, now how can I get browser to see it?

[Tech Support]

You need a web server like M$ IIS or Apache. I would rather chew tin foil
than run an IIS server even if it was on a win machine.

You can install the win version of the Apache web server and then just
browse to http://localhost/ to view your work.

I think only fully qualified domain names and paths are in the HTTP spec but most/all

support relative names in Location (not that they have to).

MySQL and PHP timestamps are in different formats. MySQL uses MMDDHHMMSS
and PHP uses a unix timestamp, the number of seconds since January 1st,
1970.

You can use UNIXTIMESTAMP(your_column) in your query to get a PHP style unix
timestamp.

Although, if you explain what you are trying to do a little better, you
could probably do the comparisons a lot easier in your query and not involve
PHP at all.

SELECT * FROM your_table WHERE your_column > your_column + INTERVAL 10
MINUTE AND your_column != 0

That looks equivilent to what you're trying to do in PHP. You might have to
say your_column+0 != 0 to get your_column as an integer and not a string.

It does this because you have willfully dis-regarded the warning messages!

You did so by not using error_reporting(E_ALL) at the top of your scripts,
or similar setting in your php.ini or .htaccess

As a result, you have some SECURITY HOLES in your scripts.

Until 4.2.x where register_globals was turned off, a malicious user could
do:

http://nadrew.com/whatever.php?blah=Hack!

Now, the $blah that your code assumes is blank is *NOT* blank, and I've put
stuff into it you've never even considered might be in there...  And it
might be malicious code.

Now, if you were *REALLY* rigorous about checking values/data/content of
*ALL* variables, and not just the ones you *thought* were coming from the
user, that would be fine, but since you almost for sure didn't, it's an
unacceptable risk.

Re: [PHP] PHP UPGRADE on LINUX

[Tech Support]

It really depends on what version you have now.

I'd say the biggest thing to look out for is the register_globals, which is
now defaulted to "Off". This will break lots of sites!!! Turn it on unless
you want your phone to ring for days. Users should, however, be urged to get
used to coding with it off. It can be turned off on a per directory basis
using .htaccess.

I have not actually tried this but one of our users reported a problem with
setcookie. He was doing this:
setcookie('username', $username, "", $protected_dir);
The manual says you must use an integer for the expire argument and cannot
escape with an empty string so I'm surprised it ever worked at all, but he
says it did work before the upgrade. I had him switch to this:
setcookie('username', $username, 0, $protected_dir);

Other than that you might have some Redhat specific problems that I'm
unaware of. I don't see why you people put up with that rpm crap. :-)

Re: [PHP] How can I get my session variable to pass to anotherpage?

[Martin Clifford]

You have to have session_start() in each page in order to carry over session 
variables. :o)

Hi,

I have a form that calls a PHP script which sets a session variable and
redirects to anopther URL as such:

session_start();
$HTTP_SESSION_VARS['userid'] = "someidnumber";
Header('Location: ' . 'http://www.mydomain.com/welcome.html');

On welcome.html, I have the following code:


echo 'userid: ' . $HTTP_SESSION_VARS['userid'] . '
';


When I run it in my browser, the value of 'userid' is empty.  Anyone know
why?

The mailing list archive:
http://groups.google.com/groups?group=php.general

Good search terms:
hyperlink "regular expression"

Yields this article:
http://groups.google.com/groups?q=hyperlink+%22regular+expression%22+group:php.general&hl=en&lr=&ie=UTF-8&safe=off&selm=3A248B2C.13ED233C%40analysisandsolutions.com&rnum=2

Which has an excellent [shamelessly patting myself on the back] hyperlink
regular expression for ereg*:

  "(http://|https://|ftp://|gopher://|news:|mailto:)
  ([[:alnum:]/!#$%&'()*+,.:;=?@~-]+)([[:alnum:]/!#$%&'()*+:;=?@~-])"

Do note, if the last character of the URI is a "," or "." it assumes those 
are punctuation and leaves them off.

Enjoy,

RE: [PHP] php redirect

[Martin Clifford]

Learning about HTTP protocol helps a LOT with understanding headers.  Basically, the 
headers are generated by the server to tell the client (browser) what to do.  If you 
send ANYTHING (even a hard return) before the header function is invoked then you will 
get this error.  In essence, if you are going to use the header() function without 
output buffering, then it should be just like this:

—--top of text editor

—-- End of text editor

Re: [PHP] Help: header function

[Tech Support]

>Kamesh's trouble was he was refering to something like http://mypage.php .
I figured it would save time to just get rid of the protocol and go
relative.

I'm aware of the spec for header, but I have always used a relative URI and
just about all the code I've seen uses relative also. I would be interested
to know of any possible problems as well. I suppose it would be good
practice to start using it correctly. I mean, even with trans-sid set to
"on" session ID's are never sent in header redirects or anything containing
a full URI anyway so it's not like it's going to mess anything up... unless
you moved your code from one site to another and hard coded your full URI in
all your header redirects... yikes!!. That's when a main config file would
come in real handy :-)

Re: [PHP] sessions

re php info:

put this into a file, put it on your server, and call up the page in a
browser:



it will show the settings for php on your server.  As Jim suggested below,
you should check the register_globals setting.  If register_globals is on,
you'll need to use the _Get function.  see more on this by looking up
register_globals and _Get in the php manual at php.net

You CANNOT reliable set a cookie and re-direct in the same script.

Never gonna work across the board on browsers/servers.

Call it a "bug" if you like (though it's not) but it will NOT work reliably
on multiple platforms.

Re-design to just send the Cookie, and then include the page they wanted in
the first place.

Also, what's to stop me from setting my own Cookie?  Are you using an
un-guessable value for the Cookie?

[PHP] Re: mail() function

[Richard Lynch]

>what has to be configured, and how, on a bsd server to allow the mail()
>function to work in php? using sendmail?

php.ini
Use the path to sendmail there, with the -t as suggested, and *YES* the
quotes *ARE* supposed to be part of it:

sendmail_path = "/path/to/sendmail -t"

You may also need to ease up restrictions in sendmail.conf so that the PHP
user is *allowed* to send out email, forge headers, and other fun things
that are pretty essential to making mail() useful.

You may also want to create a specific new user, different from the usual
"nobody", and use that for User in httpd.conf, so that PHP (all of Apache,
really) runs as 'www' or 'httpd' instead of 'nobody'

It will stop a few stupid people trying to abuse the lack of restriction on
email sending...

Not *really* much of a barrier, but every little bit helps.

[PHP] what do you wish you knew then now?

[Peter J. Schoenster]

Hi,

I'm still learning PHP. Against suggestions from most of this list I 
took the Brain Bench test and got in the Master category :) but even at 
RHIC I scored in the expert range on their test. It must be the 
similarity to Perl.

Anyhow, I was wondering (and I've asked this in a different way before) 
if some people with "experience" might suggest certain functions or 
classes etc. that you only encountered after perhaps writing it 
yourself. This happens a lot in Perl. Many Perl programmers will write 
a template system only to stumble upon the vast repository at CPAN 
afterwards. So I always tell new Perl programmers to search CPAN first. 

Allow me to show my ignorance. I use the following site to find stuff 
before writing myself:

http://www.phpclasses.org/

But I'm not using Pear for anything and never even look wherever it 
might be. I hope this is not like a Perl programming ignoring CPAN. Ah, 
I have it in my bookmarks here:

http://pear.php.net/manual/en/faq.php

I think this is the standard to follow for documenting code:

http://www.phpdoc.de/

When I installed PHP on my windows box I saw all the things I could do 
to the ini file. I much prefer to strict environment. I wrote a LOT of 
code that was not like it should have been. 

I would guess that if I wanted to follow an accepted coding standard 
this would be the one:

http://pear.php.net/manual/en/standards.php

And that's about it. I name files .inc or .cls or I use .php rather 
arbitrarily I must admit. Only .php files are returned to a client as 
that was brought up in a recent thread.

Any tips or suggestions very much appreciated. 

PLEASE NOTE. I know that of course I'm free to code however I want. I 
fully understand that. But having worked on websites where every 
programmer coded however they wanted ... well, I've become a fan of a 
standard outside of myself. No point in saying that I can do it however 
I want, that I know.

Well...

There are several options:

1. Make the files be delete-able by "nobody"  This, of course, means *ANY*
other user on the system can delete them whenever they want to.

2. Use PHP (CGI) running under a cron job to delete the things that are
"old" or somehow marked for deletion by the web-page.  The cron job can be
schedule by a real user, and will have all their powers.  This is probably
"safest" and "easiest" of all the options.

3. Add another mime-type to httpd.conf and run a *second* PHP as CGI under
that mime-type (and filename extension) and then suExec that to run as the
owner of the files.  Once again, *anybody* who can use the mime-type can
then run as that user, so be sure you pin-point the (using httpd.conf
) this into a directory only *YOU* can put PHP scripts, or you
might as well just do 1.

4. Write a sudo shell script that allows *ONLY* the files in question
(either restricted by directory or name or something similar) to be deleted
by nobody.

There are probably more options...

Even though you said "--with-ldap=shared" it just didn't "work"

You'll have to do ./configure again and figure out why LDAP didn't get in
there.

For starters, try losing the 'shared' crap.  It's just not that big a deal
to have it static -- Not worth pulling hair out anyway.

You can log your ./configure output better than usual using:

./configure ...  2&>1 > configure.output &

Then you can use:

tail -f configure.output

to see it scroll by, (control-C to quit)
or even:
less configure.output
to check it later.

I'm not sure it matters so much *WHICH* version you use for those packages,
as it does that the version you tell PHP you are using matches the one
actually *IN* your system...

If you tell PHP you have libpng 1.2.3, and that's the headers it uses, but
your OS actually has 1.2.4 or 1.2.2, it's going to crash, almost for sure. 
The farther apart the versions, the more quickly you'll notice the crash. 
Very "close" versions might have only a couple functions out of sync that
will puke when you try to use them.

Uninstall all the damn RPM's, and install the tarballs.  Look inside the
libpng/jpeg directory and find the header files.  Do a "locate" on the ones
that seem pretty likely to have always been there for jpeg (eg "jpeg.h") and
make sure you don't have any copies of that in your /usr/.../include/
directories.  If you do, get rid of all the *.h files that came from the
jpeg library, *and* the libjpeg.so files in the parallel /usr/.../lib/
directory.  Then install from the tarball so that there is one, and only
one, libjpeg on your entire hard-drive.  Remember to do ldconfig after every
"make install"

[PHP] mysql question

Sorry this may be a little offtopic, but I am currently moving a site I was
developing from coldfusion+MSAccess to PHP+MySQL. I remembered reading
somewhere that there is a utility that will convert/transfer (data and
structure) a MSAcess database to Mysql, and vice versa. Anyone know? Thanks

Here is the code that starts and registers the session. It is  login page 
that logs in to itself so the form that produces $_POST["username"] is 
actually on the same page, but nothing happens until the user logs in. It 
there is something in this code that is not correct or making the other code 
from the previous mssages not work please let me know. Thanks again for all 
of the help.

There are TWO possibilities:
1. You already *HAVE* MySQL succesfully installed and running and now MySQL
is saying, "Excuse me, but this little /tmp/mysql.sock file is telling me
that I'm already running!"

2. You managed to crash MySQL so badly that it didn't clean up after itself,
and that /tmp/mysql.sock file is a BOGUS version of 1.

You can be *SURE* which is which by doing:

ps auxwww | grep mysql

Either you see some kind of 'mysqld' in there, in which case it's already
running, or you don't.

If it's *NOT* running, it's perfectly safe to just destroy the
/tmp/mysql.sock file.

If it *IS* running, do *NOT* remove that file -- You will cause yourself
major pains if you do.

[PHP] sessions

[Tyler Durdin]

I used this logout page using sessions a while ago and it used to work 
great, but now it doesn't work. The only thing i have changed is my version 
of php. Can someone take a look and see what i have to change?



then a little further down i have this

";
 } else {
echo "Could not log you out.";
 }
} else {
echo "You have not logged in; therefore, you cannot logout.";
}
?>
It seems to log me out still, but it always gives me the "you have not 
logged in; therefor, you cannot logout" message. i also checked it with a 
script to see if my original sessions were actually registering and it 
seemed that they were. i am stumped. Any ideas would be greatly appreciated. 
Thanks.

[PHP] Logging: Best archive method

[Julio Nobrega]

  Hi all,

  I am serializing every get, post, cookie and server variables to log them. 
I was using mysql to store this data, but I've generated with 900 pageviews 
a 5 (five) MB table. Now I am using the bz2 extension to accomplish this, 
but I am not sure if it's the best method.

  Are there any better alternatives? I must log this data for every 
requested page since it's for a bank application (ever had the Central Bank 
of your country asking for log files? ;-)

  Thanks,

   echo "$var" OUTPUTS the contents of $var

2)  Checkout the func_get_args() function.

[Richard Lynch]

>Is it possible to make the browser wait say, 5 seconds before redirection by

>outputting headers

The header version pretty much hits the browser long before your HTML, and
then the browser will immediately move to the new location, and, in fact,
PHP probably won't even bother to send your HTML since, what's the point?
now that all the browsers are supporting the re-location header.

In short -- No, you can't do that with headers.  If you want that 5-second
"flash" of a page, stick with META tags.

People who are in areas with active PHP User Groups may well have opted to
skip meetup...

I signed up, if only to be sure any event was informed of the existing user
groups, but I dunno that I really expect a Chicago event to happen when we
already meet monthly, no twice monthly now anyway...

But hey, I'm not opposed to a more informal gathering.

Went to the slashdot one last night, and had a nice time, though it was in a
much too expensive (Guinness $6 Martini $10) joint, but the bread and oil
was free, so with Guinness and bread, who needs to buy a meal? :-)

If you got it installed.

insert a script called php_info.php on the companies webserver.

here is it's contents:


That will give you lots of info about the configuration of PHP.

do the same thing on your PC.

if they are differant:

Use windows explorer/my computer to browse to C:\WINDOWS\

then find a file in that directory called php.ini.

Check the settings against the ones shown with php info.

change them to the isp/companies config.

uncomment (remove the # at begin of line) the following lines in 
/usr/local/apache/conf/httpd.conf

Apache 1.3.26 default httpd.conf does lack of this entries. You have to add them 
instead of uncommenting

AddType application/x-httpd-php .php
AddType application/x-httpd-php .phtml
AddType application/x-httpd-php .php3
AddType application/x-httpd-php-source .phps

Since PHP Version 4.2.1, »register_globals« are set OFF. This can bring you in 
problems running PHP-Code not using the $HTTP_GET_VARS methods. To enable 
register_globals edit the
following line in your /usr/local/lib/php.ini:

register_globals = On

[PHP] imagettftext, GD2, and Freetype

[Sean Coates]

Hello, I'm playing with imagettftext:

http://sean.caedmon.net/ttf_example.php?text=PHP

This works fine with some fonts, and not fine with others:

http://sean.caedmon.net/ttf_example.php?text=PHP&font=a

The (broken) font in question is available at:

http://sean.caedmon.net/new/fonts/TRIACSEV.TTF

I read that this might be because of a non-unicode font..

how can I check this?
is there a way to unicode-ify a font? (-:

Thanks,

Since I'm always looping through choices in my database, and not hard-coded
values, it's really no trouble to do:

while ($id = ...){
  $selected = $id == $previously_selected_id ? 'SELECTED' : '';
  echo "...\n";
}

If I *really* want hard-coded options, I'll just put them in an array and do
the above.

create table cart(
  session_id char(32),
  item_id int
);

Then, if I have item #42, #57, and #314, there will be 3 rows in this table
for me:

adsfqweradfzxcvasdfqwer 42
adsfqweradfzxcvasdfqwer 57
adsfqweradfzxcvasdfqwer 314

So you can just:

select item_id from cart where session_id = $PHPSESSID

[PHP] php 4.2.2 on redhat 7.3

[Fifield, Mike]

I am trying to figure out how to upgrade php from 4.1.2 (which is the
default that comes with redhat 7.3), to version 4.2.2. From the small amount
of documentation I have been able to find on the subject, it looks like I
need to download a rpm. Is this the best way to do it or would it be better
to try to use the install files off of php.net, and if the php.net install
files are the way to go, how would I go about installing them over the
current copy of php. I know this may not be the proper list for this
question but I am also sending this email to the redhat list in hopes that
someone from one of these two lists can point me in the right direction. 
 
Thanks in advance for any help.

[PHP] exec() not working in one script...

Frustrating!

I have scripts that do this exact thing, on this exact server, for that
matter in this exact set of directories, now it will not work;

$filename = "NIIRTQWCDR." .  date("Ymd") . "." . $cycle;

//open new file and write records to it
$cdrfile = fopen("/usr/local/www/data.default/rcr/" . $filename, "w+");
while($cdrrow = mysql_fetch_object($dbcdr)){
fputs($cdrfile, $cdrrow->whole_record);
}
fclose($cdrfile);
//move file into outgoing directory
exec("mv /usr/local/www/data.default/rcr/$filename
/usr/local/www/data.default/rcr/outgoing/$filename");

The file gets created just fine, gets populated just fine, it just will not
move. *g*

Well, it's Friday afternoon and the pre-pub run debates have started :^]

The choice of arguement today is born of the fact that I advised a
newbie to
always use mysql_close() to close the connection to the database. It's
good
form and will cover any ills where the database connection fails to
close
for some other reason (say the user stops the page from loading after
the
connection is made). I know that it is not required, but always being
competitive I thought I would turn to the group for a concensus, whether
I
am right or wrong.

Thoughts?

PHP 4 is very aggressive about reclaiming memory.

Don't bother with the unset, unless your array is *HUGE* and you really need
it gone immediately...  Even then, I suspect you won't find any difference.

RE: [PHP] php redirect

[snip]
Learning about HTTP protocol helps a LOT with understanding headers.
Basically, the headers are generated by the server to tell the client
(browser) what to do.  If you send ANYTHING (even a hard return) before the
header function is invoked then you will get this error.  In essence, if you
are going to use the header() function without output buffering, then it
should be just like this:

As said before you can use Output Buffering to prevent this;

Good luck. I had a summer job once (would've been longer if my boss 
didn't spend all the company money and had to shut the company down) 
where we used ASP for all our dynamic pages. It's a joke. You go (back) 
to using dim statements and VBScript! Of course you can use JScript, but 
that's even more difficult at times. Connecting to a server? There are 
methods, but error reporting is not ASP's best feature.
IMHO, stick with PHP, maybe a bit of Perl, but anything you can do in 
ASP you can do better in PHP.
