RE: [PHP] Nasty DoS in PHP
Very odd indeed. Well, here's my setup:
Windoze2K
PHP 4.1.2
Apache 1.3.something
Accessing it via IE 6.0, although this should not have any bearing on
anything
I'd be interested in knowing your versions and the versions of the first guy
that posted about this. Maybe he has the same setup as me, or close enough,
but both of us are different from you. My browser just kept loading and
loading like all was well, while task manager was skipping all over the
place and I had to wait 5 - 10 seconds after I moved my mouse for the cursor
to move. I timed the script, and after 30 secs, it was still going (although
I stopped it soon thereafter to keep from having to reboot). So I reset
php.ini's execution time limit down to 5 seconds and ran it twice more, and
both times it went well past 5 seconds.
Of course, none of this bothers me as I won't be putting while(01) {
header(A) } into any of my scripts, nor was I ever planning on it! :)

[PHP] Re: mod_rewrite
Seriousely speaking, I don't think I can create you a working example here
because your case might be a whole different one, so you'd better read the
docs to get it right. To just give you an idea, here's what I use on
PHPBeginner.com:
# VHosts:
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} -f
RewriteRule ^(.+) - [L]
RewriteRule ^(.+) /index.php?%{QUERY_STRING}_PHPB_URL=$1 [L]
basically in human language it is:
Line 1: action: start Rewrite Engine
Line 2: condition: if the requested file exists
Line 3: solution: go to the untouched URL (the engine would stop here)
Line 4: alternative: if arrived all the way to this line go to
/index.php?query=URL
So, in the root we only have one single file (index.php) amd all the
requests are coming in to it as $_GET['_PHPB_URL'], there we take over the
game and decide what instances to lunch up from some shared libraries
outside the root.
In your case I think it would still similar, except, you could read the
apache docs better and assign more variables in your regex so you get the
correct data. Don't be too lazy, soon or later you will need Regular
Expression again, so thi is a good chance to learn them. :-)

I could really use your help with this. The examples I have received from
everyone thus far have not worked, including the last one that you posted.
This is the situation:
I have multiple domains, each with multiple subdomains, all of which
automatically point to the root of my web environment. I have only one
file that does all of the work for all of these websites/webpages, and
that is the index.php file in the root. This file is smart enough to
parse the url being accessed and create an appropriate page based on a
very complex set of rules.
Originally, I was using the ErrorDocument 404 to make it access the
index.php file, but this has some inherent flaws. The biggest problem was
that forms that were being posted to a page that doesn't really exist
never maintained the posted variables (due to the 404 redirect.) Another
limitation was that it just created a bunch of unnecessary error messages
in my error log since there are no real pages on my network, even though
it pretends there is.
So, I need to use mod_rewrite. That is apparent now. The problem is I
know nothing about creating regular expressions. I simply need it to
rewrite the url for any file that does not exist (it should not try to do
so for a file that really does exist, say an image file) and it needs to
have the following rule:
A*.B*.C*/D*.E*
Where A is a subdomain; B is the domain name; C is the top level domain;
D/E are a file or directory.
Some examples would be:

RE: [PHP] Nasty DoS in PHP
Good day, Just reading this thread, figured I would put my $0.02 in. This is apparently a known problem. It seems to occur whenever the php script uses lots of memory, actually, and it does the same thing whether it's run standalone or as a module. I first experienced it when I had a PHP script load a 10 meg LDAP database into memory, which took some 90 Megs of RAM to do (overhead, I guess). If I ran the script standalone, it wouldn't quit right away. If it was run as a module, Apache would have to kill the child off (it logged this activity) if I asked Apache to shut down. If I ran the script a few times, all of the memory of the machine would be used up, and I'd have to kill off Apache to get it back.

Darren Gamble wrote: This is probably just one of those cases that by the time the application determines that its child has exceeded its configured limits in resources, there are not enough resources (memory in this case) left to do the housekeeping and kill off the child. An acceptable algorithm to handle this might be difficult, namely, Apache would possibly have to keep track of the amount of heap left to it, make a difficult decision to kill the child before it exceeded its configured limits. In the mean time, sendmail, running on the same machine as Apache, grabs a bunch of memory and Apache, doing its best with what it thinks is available, gets screwed anyway with its new, sophisticated algorithm. Sendmail dies too. Maybe kerneld dies too. The machine dies. Er, I'll leave this to the CS researchers. We ain't gonna solve problems like this. I am not even sure this is worth a bug report... If there could be a moral to this thread, it is, go buy a few more Gigs of memory. _justin === Good day, Just reading this thread, figured I would put my $0.02 in. This is apparently a known problem. It seems to occur whenever the php script uses lots of memory, actually, and it does the same thing whether it's run standalone or as a module. I first experienced it when I had a PHP script load a 10 meg LDAP database into memory, which took some 90 Megs of RAM to do (overhead, I guess). If I ran the script standalone, it wouldn't quit right away. If it was run as a module, Apache would have to kill the child off (it logged this activity) if I asked Apache to shut down. If I ran the script a few times, all of the memory of the machine would be used up, and I'd have to kill off Apache to get it back.

[PHP] Re: How to create, name and start PHP sessions
In your example, simply place this line in your code (on *every* page you want the session to be on): session_name(HasLoggedIn); session_register(username); If your PHP was compiled with '--enable-trans-sid' you shouldn't have to worry about anything else. PHP will automatically store the session ID in a cookie, or it will pass the session ID in your HTML links. If it wasn't compiled with '--enable-trans-sid', you'll need to use the constant SID.

In your example, simply place this line in your code (on *every* page you
want the session to be on):
session_name(HasLoggedIn);
session_register(username);
If your PHP was compiled with '--enable-trans-sid' you shouldn't have to
worry about anything else. PHP will automatically store the session ID in
a
cookie, or it will pass the session ID in your HTML links. If it wasn't
compiled with '--enable-trans-sid', you'll need to use the constant SID.
Example:
--
?php
session_name(HasLoggedIn);
session_register(username); ?
Welcome ?=$username;?. !-- assumes user has already entered a username
on
some other page --
a href=nextpage.php??=SID;?Click here to continue./a

[PHP] function returning true or errors
I am writing a function that performs some actions. I would like to
return true if the actions succeed, or return an error message if the
actions fail. How should I go about it? The following code doesn't do
it, because the returned error message is interpreted as a boolean
true (I think that's what's happening):
if (custom_function() == true) {
print Custom Function succeeded!;
} else {
print custom_function();
}
I would actually rather just have the error message generated by the
script that calls the function, but the function performs some logic
that determines what kind of error message to give. I was thinking of
having the function return 1 if succeeds, 2 if error code A, or 3
if error code B, and then a switch statement could decide what to do in
the calling script -- but does this sound sloppy?

[PHP] php snmp
Hello...
Could some one please direct me in the right direction.
I am trying to get an snmpwalk on an snmp device.. I have set up the
community and IP correctly..
I can do a manually by doing the fallowing:
snmpwalk 126.4.202.157 public
from a terminal,,, and I do get some responses
if I use the fallowing code threw apache..
?php
$a = snmpwalk(126.4.202.157, public, );
for ($i=0; $i count($a); $i++) {
echo $a[$i];
}
?
and call this threw a browser
I get the fallowing:
and it seem as the page times out... but its very quick...almost as soon as
I call the page.
Other PHP pages work fine...
I'm running on a Dell PIII Duel 500 w/512Meg Ram running SuSE 7.3 SMP
I have compiled net-snmp
using ethereal.. I can see the snmp gets get-next ... as well as the
responses...
Anyone have any idea... ??

Your way would work perfect except that I simplified the function I
posted, for illustrative purposes -- a mistake, I realize. The returned
error message is actually composed of an imploded array, whose contents
are entirely dependent on the code in the function (basically it varies
depending on circumstances, so I can't write a test for it).
I ended up just performing the checks in the script itself, rather than
in a function, because I was only using a function as a subroutine to
keep my script's switch() statement nice and clean. But in this case,
it just was too much trouble (I was also running into a situation where
I had to deal with a global variable, etc). Since I don't really need
this anywhere else in the script, I don't really even need it to be a
function.
Thanks for your input though, Julio.

RE: [PHP] function returning true or errors
Rather than using true and false you can use 1, 0 it saves key strokes,
reduces script size, etc
Also use ' instead of if you don't need it evaluated by PHP.
if (custom_function) {
print 'Custom Function succeeded!';
} else {
print 'There was a problem!';
}
One thing I've done in the past is return a variable with a message and an
error code for example
function check_sheet() {
// if first name is less than 2 characters fail check and provide an
error
if (strlen($_POST['firstname']) '2') {
$return['status'] = '0';
$return['message'][] = 'First name must be at least 2
characters long';
}
// use if instead of elseif so we can return multiple error messages
at once
if (strlen($_POST['lastname']) '2') {
$return['status'] = '0';
$return['message'][] = 'Last name must be at least 2
characters long';
}
// if we have not encountered an error set return status to 1 (true)
if (!isset($return['status']) {
$return['status'] = '1';
}
return $return;
}
Now in my main script I would perform checking like this
// execute check_sheet function
$check_sheet = check_sheet();
if ($check_sheet['status'] == '1') {
// if the function returned 1 (true) display confirmation
print 'Thank you for your submission!';
} else {
// if the function returned 0 (false) display error messages
for ($i=0; $icount($check_sheet['message']); $i++) {
print $check_sheet['message'][$i] . 'br';
}
}
unset ($check_sheet);
This is example code written in my client for reference. This code will
allow you to return multiple error messages without echoing html code from a
function.

[PHP] Tabs + SELECTED
An interesting problem has surfaced while finishing the coding for an input form. The usual text inputs fields are in place for first name, surname, address etc. However, I've created a drop-down list for state and country. Since these drop-down lists have OPTION SELECTEDIn USA/Canada , tabbing in the form jumps over these drop-downs [simply becuase they're filled]. I would like them to be included in the tabbing. Originally I used tabindex to control the flow over optional fields. I deleted the tabindex since the behavior of the form was erratic and non-logical in flow. Any ideas on how to circumvent the default behavior of OPTION SELECTEDblah, blah , blah?

Not sure what you're tring to achieve, but that only checks the file's

is a JPEG, since people can put malicious data into a file named xxx.jpg

Make sure you aren't sending any HTML to the browser for any reason before

Surefire way to prevent this error: place the following line as the first

ob_start();

In your example, simply place this line in your code (on *every* page
you
want the session to be on):
session_name(HasLoggedIn);
session_register(username);
If your PHP was compiled with '--enable-trans-sid' you shouldn't have to
worry about anything else. PHP will automatically store the session ID
in
a
cookie, or it will pass the session ID in your HTML links. If it wasn't
compiled with '--enable-trans-sid', you'll need to use the constant SID.
Example:
--
?php
session_name(HasLoggedIn);
session_register(username); ?
Welcome ?=$username;?. !-- assumes user has already entered a
username
on
some other page --
a href=nextpage.php??=SID;?Click here to continue./a

Hope that helps!

Re: [PHP] Re: verify file types when uploading to server...
Unix systems have a program called 'file' that will look inside a file to
try to figure out what sort of data it contains, regardless of how it's
named. Generally it just looks at the first few bytes for a telltale
fingerprint but there are all sorts of rules for different file types.
This is similar to the mechanism IE uses to override server-sent MIME
types.
You can send the path of your uploaded file to the 'file' command and
parse the output to see what sort of data appears to be contained within.
Try it on the command line to see what sort of output it produces for
various file types.

Not sure what you're tring to achieve, but that only checks the file's
name. You might want to use file (man 1 file) to verify that it actually
is a JPEG, since people can put malicious data into a file named xxx.jpg
and perhaps fool IE into doing bad things.

I am wondering if any one has a good idea on how to do checking
based
on
a
files extension, what I am trying to accomplish is to be able to
upload
files to a webserver however I only want to have .jpg files
uploaded.
If
anyone has a good way to do this please share.
Thanks in advance,

[PHP] php printer functions...
I'm running PHP 4.1.1 on a Win2K box. If I understand the manual correctly, the printer functions have been integrated into PHP as of v4.0.4. However, when I try to call any of the printer functions, nothing works. Any ideas or suggestions?

[PHP] difference between $foo and isset($foo)
Hi,
I am looking at some codes. Some authors use $foo and isset($foo)
interchangeably. Just to want to make sure that the statement,
if ($foo) { ... }
is different from
if (isset($foo)) { ... }
Right? if ($foo) means variable exists and can be null. Whereas, isset($foo)
means that the value in $foo cannot be null?
Regards,
Norman

Not quite (or maybe I just don't understand your sentence).
if ($foo)
will be true if $foo has been set to some non-null (and non-zero) value.
It will be false if $foo==null.
On the other hand,
if (isset($foo))
will be true will be true if any value at all has been assigned to $foo,
including null or zero. It will only be false if $foo has never been
assigned in this scope. However, bear in mind that ($foo) will still
evaluate to null even in this case.

Norman Zhang [EMAIL PROTECTED] wrote: Right? if ($foo) means variable exists and can be null. Whereas, isset($foo) means that the value in $foo cannot be null? you've got it backwards. 'if (isset($foo))' tests that the variable has been set to some value, possibly including false or null. 'if ($foo)' tests that the value of the variable is true. jim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
