[PHP] Why Should I Use Zend Optimizer?
I posted this on the Zend.com forums but have not been able to get a response yet. So I decided to ask the people that know. I do not understand the need for an optimizer. What exactly is Zend Optimizer optimizing? If it is changing my code, then how about if I just learn how to code better? Is that all that Zend Optimizer is doing? Making my code better? Instead of making a program to fix all the dumb things that programmers like me do, why not show us what is not working. If post-incrementing is slower than pre-incrementing then I will just start pre-incrementing. What if I already write perfect code? Would I still benefit from having Zend Optimizer on my system? In other words, is Zend Optimizer a program designed to help poor coders have faster running code despite their lack of skill? Or is it also optimizing other things? If so, why are those things not already optimized? Can anyone help me unfold this mystery? I have read quite a bit about what Zend Optimizer is and perhaps I have missed the point. So if there is a document that explains this, please direct me to it. Thanks, Jonathan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Downloading very large files

Thank you for the input. For now we are just using PHP to create symbolic links to the video files and the links are removed when they are done viewing the video.

Re: [PHP] Something is messing up the php output
Yes, it has happened on different servers, none of them is bleeding edge, still using Apache 1.x and PHP 4.3.x. The sites are not using any character sets other than default. The machines are in a heat controlled environment and monitored for change so I would know if there was that kind of problem. One of the sites that I have seen it on is an osCommerce site. Another site is a custom built site. I am inclined to think that because it happens so rarely and when it does happen it is so random that there must be some combination of events that are hard to track as being part of the same problem. Thanks for the brainstorm, you did give me some things to think about. It has since subsided again so I will have to wait for it to happen again before I can troubleshoot more. This makes it very hard. Thanks everyone. If anyone has more ideas I am still open to them. Jonathan Richard Lynch [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] WILD GUESS ALERT! Until you said on more than one server I was thinking a heat-related intermittent hardware error corrupting the file read, so a turned into some not-quite-random character...

Run it and ab stress test it and pound on it with as many different requests in as random an order you can achieve. If you can get the dev box to mis-behave somewhat reliably, try getting rid of one PHP Module after another, and re-test incessantly.

I'm not sure about variable expansion with backticks(I don't use
backticks, if necessary I use shell_exec() instead). I'm just after
installing a fresh SuSE 9.1, and php is giving me a segfault at the
minute, with that particular code, but if you were using double quotes
you could:
$command = adduser -l=$dist_id -p={$user['password']}
--f=\{$user['name_first']} {$user['name_last']}\;
bearing in mind that the variables have been {}'ed, and your double
quote around $user['name_first'] and ['name_last']) has been escaped
to \
you can use shell_exec($command), which is identical to the backtick
operation.
Having that said, you should consider using alternative program
execution instead, instead of using the shell. What do you need the
shell for? You might(albeit unlikely) also come across a situation
where the shell is something like /bin/false, or /bin/falselogin, or
/bin/scponly, or basicly something that doesn't particularly work that
well as a shell.

Re: [PHP] Page that checks if a user exists on a remote system
Richard, Very good point, and you are correct, I am not looking to hire an army and spend tons of time and money on it. I have since rethought this, thanks in part to this thread. I have decided to go with something more secure. Since I have a database of users already for the site on ServerA, I will just set up a cron job on ServerB that runs a script that queries that database and then adds, edits, removes users accordingly. That way the access of the shell is being done always by a trusted system only user. I will put an extra table in my database called something like user_email_account_management_requests and the remote script with check that for any tasks it needs to do.

$idResults = `sudo -u admin ssh [EMAIL PROTECTED] id usertocheck 21`;
echo id: (.$idResults.)\r\n.\r\n;
if (ereg(no such user, $idResults)) {

And, here are the results that I get when I access the above code with my
browser:
*-*-*-*-*-*-*-*-*-*-*
id: (id: alain: no such user
)
id blah!
*-*-*-*-*-*-*-*-*-*-*
I have added the webserver user to sudoers which gives that user only the
ability to sudo to the admin user and run the ssh command which then allows
the webserver user to ssh to the remote machine without a password since I
setup secure keys for that user.
So what I wanted to do is now working. My question now would be, are there
any security concerns with how I am doing this? Aside from doing an id
check I will also be doing a remote command to add a user to the remote
system (ServerB) from the same PHP script. I will of course escapeshellarg
any information my users submit to the script.

The real answer is: There is *NO* *WAY* to do this on a general basis,
unless you control the remote machine, or know enough about its setup, to
be certain that it will respond correctly.
ServerA and ServerB
Ah. The original poster probably has control of ServerB.
Life is now simplified immensely.
This, of course, is because the script is being run as www
who has no
place to put ssl keys.
Could this be solved by having www su to a user who has
remote access
privileges? Something like this:
$idResults = `su admin | ssh [EMAIL PROTECTED] id bigbob 21`;
su simply won't let you do that. su requires a TTY to avoid you doing
something so incredibly dangerous as this.
So, no, that won't work. And you shouldn't be trying to do that anyway.
Anyone else doing or done something like this?
Sure.
I've never done it, but many many many have.
One fairly simple thing is to create the 'www' user on ServerA so that
they *do* have a home directory where they can store SSH keys. You may
need to su to 'www' once, and do some ssh work -- ssh-key-gen or whatever
it is.
That, however, increases your risk in the event that the www user is
compromised on ServerA.
Probably the best answer is to attack this from the side of ServerB.
You want ServerB to:
Only allow ServerA to even ask.
Tell ServerA if user X is a valid username.
From the point of ServerB, making sure that ServerA is the one asking is
fairly simple. You could check the IP (which can be spoofed, but that's
fairly difficult) or provide some other means of authentication (SSH/SSL)
that ensures that ServerA is really ServerA.
Then, ServerB can just check /etc/passwd usernames. Or be even simpler to
use a shell command like 'user' (?) or 'groups' to verify that a user is
valid.
In other words, instead of writing some hacky code on ServerA to try to
poke at ServerB to get the answer you want, write some nice clean code on
ServerB to provide the answer, WHEN APPROPRIATE.

RE: [PHP] Page that checks if a user exists on a remote system
This is in reply to both Stefan and Richard, I gave it some brief thought in the past, but brushed it off as not as convenient. However, rethinking about it, it may actually be more secure. H, darn it, now you have me thinking again. Security is a big concern for me. As it is now, the web user has the ability to sudo. But that user can only sudo to one other user, who is limited, and can only run 2 commands as that user. Sooo... while the web user is certainly limited, and the PHP script will be outside of the document root of the web server, and access to that script will be through an include on an SSL connection, there could still be something that I am not thinking of. Adding the people to a database first and having a script run by cron (or some other trigger) running on ServerB that accesses the database that is on ServerA would be a nice firewall and the web user would not need any access rights or the need to sudo. Ok, I am going to break this down and rethink my strategy. Thanks to everyone. Richard, I consider myself a highly security conscious person, but you are making me think more like a criminal, and that is good. Security is very important. I will post back with my results.

Subject: [PHP] Page that checks if a user exists on a remote system
I have two servers: ServerA and ServerB. One server serves
web pages, the
other serves mail. I am making a web page on ServerA that
will access
ServerB to find out if a users exists and if not then add
that user to
ServerB with information collected from the web page on ServerA.
I have this in a php file:
$idResults = `ssh [EMAIL PROTECTED] id bigbob 21`;
echo id: (.$idResults.)\r\n.\r\n;
if (ereg(no such user, $idResults)) {
echo 'username is available!';
}
When I access the page I get:
Could not create directory '/nonexistent/.ssh'.
Host key verification failed.
This, of course, is because the script is being run as www
who has no
place to put ssl keys.
Could this be solved by having www su to a user who has
remote access
privileges? Something like this:
$idResults = `su admin | ssh [EMAIL PROTECTED] id bigbob 21`;
echo id: (.$idResults.)\r\n.\r\n;
if (ereg(no such user, $idResults)) {
echo 'username is available!';
// function addUserToServerB(vars);
}
Anyone else doing or done something like this?

Re: [PHP] Page that checks if a user exists on a remote system
Perhaps this gets more into server administration, but it is mixed so much into the php script, which is why I am asking it here. Yes, sudo was one of my first thoughts. As far as the implementation goes though. How do you work the remote access bit? Using ssh do you use the ssl cert switch so that the www user can shell into a remote machine? Or does the sudo process actually make www the root user for a certain command and can then shell into a remote machine using the root ssl cert? Or can sudo make www into a user that can shell into a remote machine? I am still becoming familiar with sudo.

[PHP] Blank Page instead of Errors
I am baffled. I really hope someone can save me. (PHP 4.3.4) I am getting blank pages (or partial blank pages if my HTML comes before the PHP) instead of errors. I know there are errors on the page because I have specifically put parse errors in my code to see if the server would give me errors, but instead all I get are blank pages. I have checked the PHP.INI file and I see this: error_reporting = E_ALL ~E_NOTICE display_errors = On I have included different renditions of error_reporting at the top of my script: error_reporting(E_ALL) error_reporting(E_ALL | E_PARSE | E_NOTICE) error_reporting(E_ALL E_PARSE E_NOTICE) ... and some others. Still nothing. Is there something that I am missing? Why can I not see any error messages?

Re: [PHP] Parse an email message for content
Ed, Thanks for the reply. Actually, I have the module version and the cgi version of PHP running on my server. I have another script that I run daily, but that is a different beast with my own content. Also, I know about egrep and preg_egrep, great functions. However, I am looking for an idea on how to actually read the email files. I have been reading about fread for reading the file and then I have considered doing an fseek to start reading where the email headers stop, and then explodeing the contents of the file separated by the = delimiter that comes in the message. However, I do not know where to start. Any pointers? Thanks, Jonathan Duncan Ed Lazor [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

[PHP] Processing Code created on the fly
I am trying to create an HTML Table which has TH headers which are different
depending upon the link clicked to access the page. Also, the content of
the TD's below the headers would be different depending on the headers and
depending on the link clicked.
I have sorted out many of the details, but one eludes me. Attached is an
example that I have created to try to prove my point. In it you will first
see two variables that have been created inside of a function. The function
is called with certain values and these variables are created and populated
with PHP code that needs to be evaluated at a point later in the file that
calls the function.
Next you will see a WHILE statement that should take the contents of the
those variables and evaluate those contents as if they had been hard-coded
in place of the variables.
So far, when I run the script as is it simply prints the contents of the
variables, which is raw PHP code, but does not process it. The results is
that the raw PHP code that is in the variables doesn't get process, but is
output at text on the resulting HTML page.
Can anyone help me figure this out? I would really appreciate it.
Thanks in advance,
Jonathan Duncan

These variables are populated and assigned in a function:

Re: [PHP] Processing Code created on the fly
Yeah, I have played with the eval function a bit, but it didn't seem to help
much. Then again, I haven't ever used the eval function before so I may not
know how to properly implement it. I have read the page for eval on php.net
several times as well as the very helpful examples, but whenever I use eval,
it just prints out the same stuff. By same stuff I mean wether I use eval
or just the variable by itself it just prints out the contents of the
variable. In the web page source it looks as if the contents were merely
echoed because it still has the $'s and variable names. Any other ideas or
examples on how to implement eval on this?
Thanks for the help,
Jonathan Duncan

You need to check out the eval() function.

[PHP] Dynamically creating PHP before it is executed
I am trying to figure out a way to dynamically create some lines of PHP code and then have it executed. This is because I want a page to display different columns in a table depending on whatever link is clicked. There are hundreds of different combinations of column headings so I don't want to make a different PHP page that is formated for each different combination. The column headings are stored in a database. So far what I have come up with is to have a starting page, that takes the value of the link that is clicked, it queries the database for that value and then does a while statement to make all the TD's for the different columns. Each TD is populated with a different variable, one for each column header. Each iteration I append to a variable to hold all of these TD's. Then I write the contents of that variable to a temporary include file and call the page that will display the table. That table then includes those TD's from the include file I wrote them to and executes the PHP that runs another query on the database and fills in the variables in those TD's. This seems like a lot of work. Does what I am trying to do make sense to anyone? Does anyone have any idea how to do this an easier way?

Re: [PHP] Dynamically creating PHP before it is executed
Bogdan,
Thank you for your comment, it actually made me think of a possible solution
for something else I am working on. However, it is just as I thought, I am
being too vague. I am most likely making my whole situation more
complicated than I need. Another idea is just to do a select * and run
the whole shebang through an IF/ELSE series to determine which headers are
being used. However, to remain on my current train of thought, here is a
snippet of my code:
include(inc/dbconnect.inc);
$sql = select columns from tablename where id=$someid;
$sqlresult = mysql_query($sql, $connection) or die(Couldn't execute
query. (7));
$columns_array = explode(,, $sqlresults['columns']);
while (list($col) = each($columns_array)) {
$sql = select coltitle from FreudColumns where colid='$col';
$result = mysql_query($sql, $connection) or die(Couldn't execute query.
(12));
$ch = mysql_fetch_array($result);
// Set the column headers
$headers .= TH CLASS=\hlink\$ch['coltitle']/TH;
// Set the item variables
$setitemvar .= \$$col = \$isr['$col'];;
// Set the measurement columns
$setitem .= TD CLASS=\\$itemclass\\$$col/TD;
}
Afterwhich I write $headers to a file, $setitemvar to a file, $setitem to a
file and call the page that is supposed to include these files I have just
writed so that the PHP code that I have just dynamically written will then
execute and the variables will be replaced.
Does this make any more sense?
Thank you,
Jonathan Duncan

I don't quite understand why you chose such a complicated solution - I
may be missing something, in which case sorry for wasting your time. But
why don't you just dynamically build the select statement and then use
the whatever_fetch_array() -- and walk that array instead?

Re: [PHP] Dynamically creating PHP before it is executed
Sam,
The questions you write are good. I am not sure why they can't. I just
assumed that if I make lines of code like:
TD CLASS=\\$itemclass\\$$col/TD
and populate them like:
TD CLASS=$itemclass$column1/TD
TD CLASS=$itemclass$column2/TD
TD CLASS=$itemclass$column3/TD
that I would have to then evaluate them on a different page. Am I
incorrect?
Thanks,

You make sense until the last paragraph.
It sounds like you are making this way more complicated than it need be.
Why write these out to files and then include them? Why not just echo
your

I want to make a web site that displays news headlines from my favorite news sites So the theory is that I fopen their web page, fread the contents of the page, look for the sections that have the news headlines (with regex I assume) and their href link information, paste that into an include file and call it when my page loads Sounds simple enough right?
