[PHP] New mailing list

2003-03-10 Thread Ron Clark
http://betterphp.org

The Better PHP mailing list is available for anyone who wants to learn
how to write secure, efficient web applications. We focus on the LAMP
(Linux-Apache-MySQL-PHP) platform but welcome other questions.

This list is intended for people who use PHP, and who want feedback on
code style, security, and other more advanced PHP topics.

Please note: this list is moderated. Anything you can find in standard
documentation will not be forwarded to the list, as we are trying to
keep the discussion about style, not syntax.

Everyone is welcome to join and learn, the goal is to get programmers
thinking about security.

[PHP] Why Can't I get this to work

2003-06-25 Thread Ron Clark
Hello all,

I have a php script that reads a flat text file with fields seperated by a
space. I explode them into an array just fine, but when I try then to load
that array into a mysql database, it doesn't work. Here is my script:

for ($i=0; $i<$number_of_alerts; $i++) {
// Split each line
$line = explode(" ", $ipfwlog[$i]);

$line[1] = intval($line[1]);

$IPFWsql = "INSERT INTO Firewall_Logs (month, date, time, fw_name, kernel,
fw_engine, rule_number, action, protocol, src
$results = mysql_query($IPFWsql) or die ("Could not execute query");

}

Any ideas why this does not work? I am completely stuck.

Thanks in advance,
RonC

2003-06-28 Thread Ron Clark
OK, normally I do not respond to my own posts, but I have been shown that I
did not get the whole script. So here it is:

for ($i=0; $i<$number_of_alerts; $i++) {

// Split each line

$line = explode(" ", $ipfwlog[$i]);

$line[1] = intval($line[1]);

$IPFWsql = "INSERT INTO Firewall_Logs (month, date, time, fw_name, kernel,
fw_engine, rule_number, action, protocol, src_ip_port, dst_ip_port,
direction, via, interface) VALUES ('$line[0]', '$line[1]', '$line[2]',
'$line[3]', '$line[4]', '$line[5]', '$line[6]','$line[7]', '$line[8]',
'$line[9]', '$line[10]', '$line[11]', '$line[12]')";

$results = mysql_query($IPFWsql) or die ("Could not execute query");

}



Again, any help with this issue is appreciated.



Thanks,

Ron Clark

[PHP] passing variable question

2002-11-11 Thread Ron Clark
Hello all,

I have a php script that reads all the files in a directory (pictures), the
outputs each picture as a link to be displayed in the main frame of the html
page. All of that works fine. I want to be able to "pretty up" the picture
out put by placing the picture into a html table so it is centered, add
color, etc. But I cannot seem to figure out how to pass the variable from
the menu page to the main frame page without using a goofy gray button form.
Anyone know how to pass a variable on just a link alone?

Thanks,
Ronnie

[PHP] php-4.1.1 and pspell

2002-01-16 Thread Ron Clark

I have a problem that I would be thankful if someone could help with.

When php-4.1.1 is compiled using pspell-.12.2 and apache-1.3.22 with
mod_ssl-2.8.22 apache core dumps when trying to start. Using the same
configure options with php-4.0.6 and apache-1.3.22 and mod_ssl-2.8.22
everything works fine. Does anyone know if this is a bug with php-4.1.1.

Operating system is solaris-8 on a sun enterprise 450

Most University CS departments prefer to teach programming using a more
structured language with stronger type casting. It is much easier to
move from a structured language to a language like perl or PHP than the
reverse after graduation. At our university we offer special topics
courses that are not on the curriculum when requested by students -
courses on PHP perl visual basic. Maybe you should talk to the CS
department head about special topic classes or department sponsored user
discussion groups.

But it returns a blank or empty. How do I convert this MySQL command

In other words, how do I specify the "y" at the end without messing
up PHP?

Consider the following:

while ($rows = mysql_fetch_object($result)) {

So why does this not return the Table names? I have even tried "echo

this?

[PHP] system command

2004-08-23 Thread ron clark
I an trying to add virus scanning to the file upload section of our 
portal using uvscan. The virus scanning is working properly using a 
system call , but I am having problems with formatting the output. I 
need to check the return value and if it is not a 0, I want to create a 
custom message. The problem is, when using system the output of the call 
is flushed to the browser before I can write the custom message so I 
have the uvscan message and then my custom message.

This is my code.
   $uvscan_cmd = "/usr/local/bin/uvscan " . 
$_FILES['file']['tmp_name'];
   $output = system("$uvscan_cmd" , $retval);

   if ( $retval != 0) {
   print "A virus was found in your file $output";
  exit;
   }
This results in the following sent to the browser.
/var/tmp/phpBFaaIa Found the W32/[EMAIL PROTECTED] virus !!!
A virus was found in your file.
Found the W32/[EMAIL PROTECTED] virus !!!
How can get rid of the first line and still have data $output? I tried 
adding a 2 > &1 to the system call and tried redirecting the output to 
/dev/null. This got rid of the first line but also resulted in $output 
not having an output.

You can use output_buffering to capture the output, or use a different 
method to make the call, i.e. backticks or exec(), which allow you to 
capture the output before it's displayed.

---John Holmes...

Thanks John. Was a simple fix. Turn output buffering on to prevent the 
output of the system command going to the browser. Capture the output in 
the $output variable then ob_clean to empty the output buffer before 
printing the the desired message.

ob_get_clean() is preferable:
$output = ob_get_clean(); // Gets the buffered output and cleans 
the buffer

Didn't need the contents of the buffer. All I needed was the last line 
which was contained in $output = system().

I thought you said in earlier email that your apache was running as user 
daemon. The tmp directory has to be owned by the user running apache. If 
you want to run apache as user apache group apache then you will have to 
edit httpd.conf and change the User and Group directives. Otherwise 
chown chgrp the tmp directory to the user/group that is listed in the 
httpd.conf file.

Re: [PHP] order of elements in $_POST super global

2006-06-08 Thread Ron Clark

Ben Liu wrote:

Hi Dave,

No, that is definitely a possibility. Right now I am using a foreach
loop to iterate over the $_POST array and determine if each checkbox
is checked or not, if it is checked, than a related piece of data is
written into the text file. This makes for pretty compact code. I
could as you suggest, simply check each element in the array manually
using the associative keys rather than using a loop, that way I could
do it in any order I wished, but the code gets rather long with a line
for each checkbox. I anticipate this set of checkboxes/boolean
responses may increase in the future also, so having the loop allows
for some future-proofing.

why not create an array with the keys in the order you want ( $array=

I have found that when learning a new language that it is a good idea to
read the whole manual it time permits, even it there are sections that you
don't think you will ever need. Later on when programming you may need to
do something and remember that function that you never thought you would
need. It never hurts to no what's available even if you don't think you
will need it.

When you do %> then you have broken out of ASP and are now writing HTML.
You then do <%=filen%> to go back into ASP to get the value of the
variable into the HTML code that you wrote. ASP is not including the file,
it is only supplying a file name for SSI includes whether apache SSI or
IIS SSI. The server parsing the HTML recognizes the HTML comment is
sentax for server side include and includes the suppplied file name.

With this new example you are still using SSI from the web server to
include an ASP file. ASP itself is not including the file.
