Asunto: [PHP] smtp mail sending on unix
Importancia: Baja


Hi,

I am running apache in a chrooted enviorment on solaris and trying to get
mail() to work over smtp rather than sendmail, but unsuccessfully. php.ini
states that this is for win32 only. Is there any solution to that? It seems
quite awkward to have the code for smtp but no option to run it.

thanks,
Jaanus

RE: [PHP] Smarty problem

What do you mean with garbage? What's that garbage?
What's the content from $entry_events ?

Asunto: [PHP] Smarty problem
Importancia: Baja


Hi,

I already posted this question in the Smarty group, without success.

I have a problem with Smarty. I wrote the following function that gets data
from a mysql database:

 function showHeadlines()
 {
  global $db;
  $entry_events = array();

  if ($this-showold == true)
 {
  $db-select(*, news, (d_kategorie = 'de_termin'), d_datum
ASC, , , );

  $entry_events = $db-fetch_array();

  $this-assignVars('termineAus', $this-aTrans['termineAus']);
   $this-assignVars('entry_events', $entry_events);
  }

The template part looks like this:

   table width=100% border=0 cellspacing=0 cellpadding=5
align=center
tr
  tdh2{$events}/h2/td
 /tr
 tr
  tda
href={$filenpath}?showold={$showold}i{$termineAus}/i/a/td
 /tr
 {section name=i loop=$entry_events}
 tr
 td bgcolor=#e2e2e2b{$entry_events[i].d_datum}
{$entry_events[i].d_zeit}/b/td
 /tr
 tr
 tdb{$entry_events[i].d_ueberschrift}/b/td
 /tr
 tr
 tdb{$place}:/b {$entry_events[i].d_ort}/td
 /tr
 {/section}
   /table


The problem is that the output in only garbage?
Is there a logical problem ?

Thank you very much

have a situation where clients will be uploading images via a web interface.

We need to process these images to create thumbnails.  In the past we have used
image but have found that the output is somewhat less than desireable and
limited to jpg.

We would like to be able to soften the image prior to resize so it is a little
clearer in the thumbnail, as well as have the option of working with gif, png,
etc...

Comments appreciated.

RE: [PHP] breaking a string into chunks

Make your own function, for example:

function transformDate($format,$str) {
  $d = Array();
  for($i=0;$istrlen($str);$i+=2) { $d[]=substr($str,$i,2); }
  return
date($format,mktime($d[4],$d[5],$d[6],$d[2],$d[3],$d[0]$d[1]));
}

print transformDate(Y-m-d H:i:s,20030917181909);

So, you can change to any format with the first arg. of the function.

Hi, all --

Now it's my turn to ask a simple question, or one that sure sounds like
it should be...

I have a 14-char date string like 20030917181909 and I need to break
it
into its component parts for a more readable 2003-09-17 18:19:09 view.
How can I do that?  Do I really need to call substr half a dozen
times?(!?)

I tried unpack() but all I ended up getting was an array with one entry
(sometimes with a very strange-looking key).


TIA  HAND

RE: [PHP] embedding PHP in MySQL

[Javier Tacon]

Instead to eval the code, try to save the query result into a new file, then execute 
this file (require_once, include).

Something like:

function executeFromQuery($query) {
  global $DB;
  $file = /tmp/temp.php;
  $code = $DB-getOne($query);
  $fh = fopen($file,w);
  fwrite($fh,$code);
  fclose($fh);
  include($file);
}

It should work.

I'm currently developing some pages where I use

Some days ago, as I said, I formated my hard disk,
installed everything again and from that day on
$_SELF[PHP_SELF] stopped working, same goes for
$_SERVER[REQUEST_URI] or $_GET[location] (which are
the solution I tried to find, without success). The
page says:

Notice: Undefined index

(for $_GET) or it just says nothing (the other ones
above, no error reported, it just displays nothing).

Inside PHP.ini I have globals set to On, but if I set
them to Off nothing changes...

Can anyone help me? At PHP.net I saw If PHP is
running as a command-line processor, this variable is
not available, but I am running it from a web page on
Windows 2000 + Xitami.

Thanks a lot for your help and sorry if I asked
something stupid, but I couldn't find any solution

RE: [PHP] Sessions doubt

[Javier Tacon]

In PHP = 4.3.3 versions, start a session when you have a session started already, 
causes a notice error and the second call is ignored.

In older versions, the second call is ignored without errors (assumes the first 
session started)

Put this to your top.php:

@session_start();

And then, remove all the session_start from the others php files, when you are done, 
remove the eat '@' in the session_start() (isn't smart)

Hi,
I have a small (simple?) doubt, if you know the answer kindly reply.

I have a top.php and bottom.php template files so that the whole site has
pretty much the same look and feel, then I have around 150 scripts that call
this files such as index.php or something.php like so:

?php
session_start();
include top.php;
subject or page matter here
include bottom.php;
?

I am relying heavily on sessions, right now its become an habit for me to
have session_start(); on every page as I start to write it, but have started
seeing some funny results as I have a session_start(); in both the calling
file and the top.php

do I really need to have it in both or just one?
or does it really matter at all?
 if just one it should be the file that is calling top.php right?

Thanks,

Dear Javier,

We have done the following as per your suggestion
15 17 * * *   /path/to/your/php/binary  /path/to/your/script.php
After editing and saving crontab file the following message pops up at the
commond prompt -
crontab:installing new crontab
crontab:error renaming cron/tmp.1885 to cron/root
rename: is a directory
crontab: edit left in /tmp/crontab.1885

It did not work.  Please suggest what to do next?

For example, you want execute a script every day at 09:00 am:
$ crontab -e
And put this line:
0 9 * * *   /path/to/your/php/binary  /path/to/your/script.php
Crontab only can say if the cron was executed correctly or not, but it
doesn't say if your script in php has sent the mail correctly or not.
For debug if the mail was successfully sent, develope the debug into your
script.
You can use a some mail classes that they have debug options (for example I
use phpmailer v1.65).

Asunto: [PHP] Urgent help required for using Cron


Hi friends,
  I have to send mail  to people automatically at specified time . Our
environment is RedhatLinux 7.3 , Apache ,mysql and php. I am writing a
program in php to send the mail if some
Condition is met. I want to activate this program at specified time using
cron facility.
So, How can we do that? Can any one help me?.

I have another problem also.   We want Cron to indicate ( through a message
or a mail)  to us that a given task is completed or not.  In the present
case Cron does a task of sending a mail to a user.  After sending the mail
we want Cron to indicate to us that the mail was successfully sent or not
sent.  This we want to know through a program because we want to use this as
a part of automation of sending mails.

Thanking you,

Siva

RE: [PHP] reboot pc with PHP

[Javier Tacon]

You can write a little script with expect (man expect) and execute it from php with 
exec().

Other solution its to write a .procmailrc in root that executes the reboot when coming 
a mail with some text in subject or boyd, so, from php you only need to send a mail.

Asunto: [PHP] reboot pc with PHP


Hi List

I've gone through the list for previous questions and the only one that
seems to be a solution is to use sudo, however, I cannot seem to get it
right.

Just as background:

I want to make a small admin utill for an intranet machine, so the
security risks don't bother me at all.

Instead of myself having to ssh into the box to reboot or do other
routine commands, I'd like to make a simple password protected webpage
that would have simple links on them like reboot, redial etc, so
that someone with some sort of responsibility can do it themselves.

Obviously these command(s) need to be run as root, so I looked at the
/etc/sudoers and added apache , BUT, in the error log it prompts for a
password.

I tried to add the option NOPASSWD: ALL to the file, but it says there's
a syntax error.

What am I missing?

Any other ways of doing this?  PS, I don't even want to consider Webmin,
it's way too complicated, I just want a handfull of predefined commands
to be run, nothing else)

Thanks

RE: [PHP] reboot pc with PHP

[Javier Tacon]

A more easy solution is that:

Make a cron that executes every minut /tmp/rreboot.sh for user root
crontab -e
Add the line:
* * * * *  /tmp/rreboot.sh

The script is:
/tmp/rreboot.sh
---
#!/bin/sh
if [ -f /tmp/rreboot ]; then
 rm -f /tmp/rreboot
 shutdown -r now
fi
---
Make executable the file with chmod +x /tmp/rreboot.sh

And a simple PHP like:
?php
exec(echo rreboot  /tmp/rreboot);
echo Ok, i'll reboot in a few seconds;
?


So, when anyone calls to this PHP, creates a file, that if its detected by rreboot.sh, 
the root will reboot the machine.

RE: [PHP] reboot pc with PHP

[Javier Tacon]

Exactly ..
Well, the script removes the rreboot file before the shutdown.

For security choose a directory for rreboot file placed in a directory that only can 
be readed/writed by apache, and the php file in the example its very simple, but you 
can ask for a password, create a log, etc ..

chown 700 /directory/for/rrebootfile
chown apache.nobody /directory/for/rrebootfile

just one little point (i'm glad i don't have to give a setuid lecture) personally
i would make sure that the location of the check file is extremely secure.

under normal circumstances, any user could write the rreboot file and cause a reboot

also, remember to remove the file again in rc.local before cron starts etc.

but i like the idea. its much more secure (from a web perspective).

 And a simple PHP like:
 ?php
 exec(echo rreboot  /tmp/rreboot);
 echo Ok, i'll reboot in a few seconds;
 ?
 
 
 So, when anyone calls to this PHP, creates a file, that if its detected by

Try to add --with-jpeg, but probably you need to install some libraries, like libjpeg

RE: [PHP] speed of mail() on two servers

[Javier Tacon]

I think that may be 'problem' from sendmail .. mail() function under
linux only interacts with sendmail, it doesn't contact to the remote
SMTP to leave the mail. Do you have the same sendmail version in two
machines? You should compare both sendmail configuration and try to
check the speed from a bash script for example.

Asunto: [PHP] speed of mail() on two servers


Hi, all --

I'm working up a [cli] script to send a personalized (ugh) email to some
[often large] number of web site subscribers.  Unfortunately, I'm
getting
lousy performance, running about 0.54 sec per email.

My partner has a mail script implemented on another machine and he's
running somewhere down around 0.10 sec per email, which is better but
still not very good for sending to 60k users.

The box (dual Xeon 2.2G with mirrored fast SCSI and 1G RAM) has plenty
of
horsepower, and it certainly shouldn't need more.  It's running RH 7.3
(Valhalla) with 2.4.20 on ext3 and has qmail installed as its MTA.

It seems to be the mail() call itself, because I can make a system call
(system, exec, passthru) to just echo the current data and it rips
through my list in nothin' flat.  So how do I tune mail() to make it
faster?  Or do I need to give up and call qmail-inject directly?


TIA  HAND

There are a lot of methods. The most common is using an array:

$_SESSION['sv_CampusList'] = Array (1,2,3,4,5);
foreach($_SESSION['sv_CampusList'] as $id) {
  echo $id;
}

If you want to use sv_CampusList as string:

$_SESSION['sv_CampusList'] = 1,2,4,5; 
$tmpArr = explode(,,$_SESSION['sv_CampusList']);
foreach($tmpArr as $id) {

Hi,

I have a list contained in a session var. I want to loop through the list,
getting the value of the current item, then do a query based on that value.
Is there an easy way to do this, or do I need to convert the list to an
array first? In the code below, $id isn't being set.

Here's my code (this is just testing stuff, sv_CampusList is set somewhere
else):
?php
session_start();
$_SESSION['sv_CampusList'] = 1,2,4,5; 
for($i=1; $i=strlen($_SESSION['sv_CampusList']); $i++){
$id = strpos($_SESSION['sv_CampusList'],$i);
echo $id;
}
?

You can play with a $_SESSION var, ..

Imagine that you have the file a.php with ..

?php
// Your code 
session_start();
$_SESSION[lastFile] = $_SERVER[SCRIPT_FILENAME];
?

And you want b.php that can only be executed after a.php:

?php
session_start();
if($_SESSION[lastFile]!=a.php) die(Access denied);
$_SESSION[lastFile] = $_SERVER[SCRIPT_FILENAME];
?

I have an application that consists of some 30 php modules.  Each one links 
to another, as you can imagine. How can I create a security mechanism that 
only allows the modules in my system to be called from one-another? I do 
nto want any of the modules to be called by typing them on the address bar. 
Of course, sessions takes care of folks who have not logged into the 
system, btu I don;t want registered users hacking around either.

I though of using HTTP_REFERER as a handshake restrictor, but it seems to 
be unstable and unreliable. Any suggestions?

RE: [PHP] PHP Interview questions

[Javier Tacon]

Yes, I gree with all.

To test their mySql level, you can show them two tables, and the results from a join 
between the two tables, so you ask them for what is the SELECT statement to get that 
results.

Example ..

Table1:
++-+-+--+
| id | name| surname | departmentId |
++-+-+--+
|  1 | John| Doe |1 |
|  2 | Scott   | Johnson |2 |
|  3 | Mikael  | Martin  |2 |
|  4 | Nicolas | Survey  |3 |
++-+-+--+

Table2:
+++
| id | departmentName |
+++
|  1 | Production |
|  2 | Sales  |
|  3 | Marketing  |
+++

Question: What's the select statement to show this results:
+-+-++
| name| surname | departmentName |
+-+-++
| John| Doe | Production |
| Mikael  | Martin  | Sales  |
| Nicolas | Survey  | Marketing  |
| Scott   | Johnson | Sales  |
+-+-++

Answer: select name,surname, departmentName from table1 left join table2 on 
table1.departmentId=table2.id order by name asc;

This example is very very easy, don't put it into your exam :)
Look for other examples searching in google or any searcher ..

Asunto: Re: [PHP] PHP Interview questions


From: Micheal Harris [EMAIL PROTECTED]

 I am in the process of hiring someone that needs to have extensive PHP and
 MySQL experience. Does anyone have any suggestions for interview
questions?
 I have no PHP or MySQL experience, and come from a non-technical
background.
 I want the questions to be technical, but I am unsusre as to how specific
I
 should get with the questionning!

How are you going to grade it, though, if you don't know PHP or MySQL?

I say you should send them to the list and let us grill them!! We'll sort
out the riff-raff.. :)

Seriously, look at their portfolio, call their references, and MAKE them
write code.

TASK: Create a PHP application that will insert names and dates of birth
into a MySQL database.

CONDITIONS: Given the PHP Manual, MySQL Manual, Notepad (or similar text
editor), and database host, user, and password information.

STANDARD: The application will run without errors when complete. The
application will accept a first name, last name, and date of birth (in
DDMMMYY format) through an HTML form and store the information in a MySQL
database. The application will list all current entries in the database in
an HTML table after a new row is inserted.

Things to look for:

1. Do they program for register_globals ON or OFF?
2. Do they check the setting of magic_quote_gpc?
3. Do they include error checking of form data and queries?
4. Is their program open to cross site scripting or SQL injection attacks?
5. Do they use a DATE type column or VARCHAR column for dates?
6. Do they write valid HTML?
7. How many files do they use to accomplish the task?
8. Do they try to add extra fluff instead of just accomplishing the task?

Hopefully others will pipe up with their comments, also. :)
