Re: [PHP] advice on sql injection/XSS prevention
Actually there is a tool available for automated validation of PHP code. It's called static source code analysis which, very simply stated, acts like a spell checker for custom developed code. This tool is very accurate at finding, especially SQL injection and XSS, and can be run directly against the source code so it doesn't need the application to be up and running. This company http://www.armorize.com/services/securityasaservice?utm_source=jordanutm_medium=post is offering this kind of tool delivered as a service directly over the Web which means you can either request that those authorized people verify thier code security before posting, or you can do it after they have posted. The tool shows the vulnerability as well as the tainted origin that introduces it and provides fix suggestions, etc so everything can be fixed in a very short time with very little effort -- no installation required.

[PHP] PHP Security!!! www.armorize.com
Hi, I would like to introduce a new tool for verifying your PHP application's security. Our product uses the most advanced static source code analysis for identifying vulnerabilities in PHP code. Right now we are working with our version 1.17 which has improved functionality, speed and coverage. We have an under 5% false positive rate which drops to under 1% with a little configuration. Our false negatives are negligible! Our language parser and transformer creates an abstract model of the code through which it runs a series of program path, inter-procedural and data flow analyses after which it can tell you not only what line of code the vulnerability lies, but also highlights the tainted variable that introduced the bug and how it propagates throught the code to become a vulnerability. This provides an end to end illustration of the vulnerability, educates you regarding the dymanics of security problems in PHP and actually provides suggetions of how you should go abuout fixing the code. The best part is that becuase it is static analysis, the application does not need to be up and running, so you can run the scans during development. We are launching our Security-as-a-Service model which represents the hosting of our core technology at our RD center, all you need to do is log-on via your Web browser and you can verify your application's security. Today we are introducing the SaaS model and are providing it on a monthly subscription basis. Purchase for one month and fix your entire code base, when you need to modify your application again, it will only cost you that month's subscription. Our introductory price is very low for this kind of tool, because there is no tool as advanced as this. But you need not take my word for it, write to [EMAIL PROTECTED] to apply for a free 2-day trial account. Please inlcude a valid business e-mail, your name, and phone number (optional). The first 50 subscribers will recieve a full month's subscription at 50% discount. The first 25 will recieve 2 months at 50% discount.

FW: FW: [PHP] Re: Please hack my app
Hi Ivo,
Jordan forwarded me your mail to provide some technical explanation.
First of all, sorry for the delay, due to recent business travels and
out-of-office events, I haven't had a lot of time to go through my
mailbox.
The product version that you were using is a trial version, which does
not support all of the most recent improvements we've added (version 1.2
will be released in January). You encountered one of the limitations,
when you noticed that calling your own functions caused a vulnerability.
Due to the way our algorithms analyzes and processes information flow
through function calls, we can sometimes determine a user-defined
function to be vulnerable, regardless of the parameters passed to it.
One simple (artificial) example would be the following situation:
function update_last_login($user_id) {
mysql_query('insert into users (id, login_date) values ('
. $user_id . ',' . $_GET['date'] . ')');
}
No matter if you sanitize $user_id or not, the function will always pass
an unsanitized user parameter into an SQL query, so the function call
will always lead to a vulnerability - this would even happen if there
were no function parameters.
In that situation, the current trial version will report those calls to
your user defined function vulnerable, possibly without finishing the
tainted information flow trace to the actual sensitive method (the
mysql_query in the case above). A complete traceback with a more
fine-grained reporting level has already been implemented by not yet
deployed to the trail servers.
By the way, we would greatly appreciate any feedback that you could give
us concerning usability and performance of the trial account.
If you have any more technical questions, please don't hesitate to
contact me.
Best regards,

Hi Ivo, Sorry for the late reply, I have been traveling. I am assigning someone to your case who will assist you in understanding the cause of the inclusion of the vulnerability in your own functions. To my understanding it is that it could be the result of a repetition of an instance discovered in your function. If you are then to include the function a number of times, the vulnerability will be identified in all those instances. However, I am assigning someone to this question who will give you a better answer, his name is Chris. As to your comments, I would greatly appreciate them.

Hi List,
As this subject may start you wondering what the hell I'm thinking,
let me
clearify:
I've been rewriting an GPL'ed PHP/MySQL app from scratch for the last
12
months or so. It facilitates storage of DNA mutations and the
corresponding patient data. Because patient data is involved, privacy
is
very important.
Now of course I read lots of pages on SQL injection and whatnot, and I
strongly believe my application is protected from this kind of abuse.
However, believing is not enough. I've had some comments in the past
about
security (previous version of the software) and although I didn't
agree to
the critic, I want to be able to say the new app went though various
forms
of attacks. This month, I want to release 2.0-alpha-01...
*** THIS IS NOT ABOUT HACKING THE SERVER ***
But about getting in the application when you're not allowed to!
If you feel like helping me out, it's located at
http://chromium.liacs.nl/LOVDv.2.0-dev/
1) Please try to get in. There's one account in the system, a database
administrator, capable of doing anything. If you get in, you can
easily
create a new user using the setup tab. This will be the prove of you
breaking my security rules.
2) Can you manage to view unpublic data? Using the Variants tab, you
can see there is currently one entry in the database (with two
mutations).
This entry has a hidden column, called 'Patient ID'. There is a
text-string in that column. If you can tell me what that string is,
you
win :)
3) Feel free to register as a submitter to see if that gives you any
rights that you shouldn't have. A submitter is only capable of adding
new
data to the database (Submit tab), but that data will not be published
immediately.
4) After a while, I will release login details of a curator account.
This
user is allowed to see non-public data and handle the specific gene,
but
NOT create new users or the like.
If you have any questions, please ask. Thank you in advance for using
your
expertise for the good cause :)
In case anyone is interested; I've created a low-level user
('untrusted')
in the system. Password is equal to username. Feel free to try and do
stuff you're not supposed to, like creating a new user or creating a
gene.

I'm sure most of you can relate. :) But, as long as people on this list are willing to discuss things with me and answer my questions, I'd greatly appreciate it! :) With respect to how this relates to you, your sessions and what Jochem wrote... If I read your above comment correctly it doesn't really sound like it applies to your problem only that you used ColdFusion to describe what you would have done in that environment. Sessions by nature are per user only and not application scoped. Of course. Jochem, feel free to jump in here if you've got time. :) Your comment may not have *really* applied to my specific situation, but I'm intrigued now. :) You said: This becomes a much more difficult issue when a program holds private data in memory that requires a specific way to access it. For instance if you stored some kind of application variable in memory (a la ColdFusion, Java, ASP) then this value would not be normally transparent to other computers without some kind of synchronization system to transfer it around. Perhaps I'm being dense (it wouldn't be the first time), or maybe a bit unimaginative, but I can't think of an instance where while a user is logged into an app and using it, that another computer (besides the web server, database server and the client machine), would need to have access to that data. Are you referring to state here? Or well other than passing data around between browser windows, I'm not really sure what you mean. I'd love it if you could find the time to expand on that. Imagine a configuration system loaded from a slow medium and cached in the running process for all subsequent page requests. The speed advantage is immense, but it violates the share nothing rule. Okay, I can see what you mean there. Only that *one* machine has the data cached, so if you were to want to spread the load out over several machines, they'd all have to cache the same configuration and any time it changed they'd all have to re-cache it, since none of the machines knows about the others... that kind of thing? To emulate this in PHP one would punt the cached data to a database so that it could be retrieved in a single lightweight query. In this respect PHP often differs from Java or ASP that often load configuration data and keep it resident for some time. That said, PHP merely forces the user into the share nothing philosophy, whereas Java lets the developer choose since anyone can write their code to share nothing if they want. In this regard-- protect the users from shooting themselves in the foot-- PHP often takes an arguably overzealous position. Okay, I think I'm starting to understand now. Right now, I'm working on a very large CF project for a national company and I'm trying to think of where I might apply the idea of the share nothing rule. Nothing leaps to mind, but it may when I least expect it. I'd still be interested in hearing from anyone who's applied this idea on any scale. Sometimes I've got to be beaten over the head with something before I can get my mind around it, so examples would help. Heck I'm *just now* starting to get to the Ah-ha! stage of OO programming (and I'm loving it, by the by), but it took what seems like forever to get there. You know? You Said: Using the share nothing philosophy such data doesn't generally exist, and if it does, then it is stored in a database. Databases are a better system for such data since they were designed
Re: [PHP] Questions from a ColdFusion Developer
Jochem,
Thanks so much for your advice.
In the end, I managed to find why that little EZSql tool wasn't working for me,
and thus what I'm *really* putting into the session variable is an array.
I understand also that each user would get a copy of the same session
variables, but this is for a small antique dealer and there will only ever be
one or two people using the admin screen which started this mess in the first
place.
Also, I'm using the auto_prepend_file to simulate the CF concept of an
application.cfm which gets included at the start of every page. I've configured
it such that if the include file doesn't exist in the application's directory,
it then goes and gets an empty file of the same name to prepend from the
default include path... pretty neat, actually.
When you said:
...the strength and simplicity of PHP stem from the decision to make/keep
PHP a 'share nothing' architecture.
What did you mean, by that? I've not heard of this share nothing idea. What
is the idea of share nothing and why is it a strength? I'd like to understand
so if I'm doing something ass-backwards (read: inefficiently), that I can
change what I'm doing.
So far, things seem to be working for me, but perhaps there's an easier way to
accomplish some of the stuff I'm doing, you know?
I'd appreciate any time you could spend answering my questions.
Thanks,
Chris

with regard to shoving stuff in the SESSION superglobal:
1. it not shared between requests by different users - meaning
that the SQL query you gave as an exmaple would still be run once
by every visitor and each visitor would have a copy of the
result set object.
2. performance-wise sticking objects in the session is possibly
something to be avoided is possible - storage and retrieval of 'complex'
structure (i.e. objects in this case) comes with a certain performance
penalty (you might want to consider using an array to store the query results)
3. you MUST load the class definitions of ALL the objects that are in your
session
BEFORE you start the session.

I've got a page that does a search on one of my tables. I'm using Justin

like:

$users = $db-get_results(SELECT name, email FROM users);
foreach ( $users as $user ){
// Access data using object syntax

So far so good. So I've got an iframe on the page which (I hope) will
eventually display the results of the search. The user will then click on
the search result for which they want to view the details, and the
information from that row will be populated inside the main page (the one
that houses the iframe).
Hope that makes sense.
Okay, so my trouble is that I don't know how to enable the page inside the
iframe to have access to the result object created by Justin Vincent's nifty
little class. In CF I can just say:
session.oResults = queryname
CF automatically returns any query as an object with the name of the query
as the object name (i.e. queryname.MyIdField, or queryname.EmployeeNumber,
etc.) Using a line like the one above (assigning the query object to a
session variable) all of my subsequent requests would have access to that
result set simply by using the object.
I'm *sure* there's a way to do this in PHP. I'm just falling short of
finding the answer. I've tried:
$_SESSION[SearchResult] = $db-get_results($query);
But it doesn't seem to work. I may have some other problem using the
object. I just re-read my error and it says:
Fatal error: Call to a member function get_results() on a non-object in
inventorymanager.php on line 93
hmm... I sure would appreciate a little guidence here. Even if my problem
is with the way I'm using the object, is the idea of assigning that object
to the session scope the right way to do this or is there a better approach.
To that end, I suppose I'm looking for an idea of the best practice.

In speaking of *large* scale applications I suppose I might be able to see where you'd want something different than the session superglobal since the more users you have accessing the app and using that scope, the more memory it's taking up on the server. I thought cookies might be used in such cases. I don't usually use cookies, because ColdFusion has an configuration option of storing session data in the system registry (windows version obviously)... which alleviates the problem of running out of memory via the session scope.

why don't you just echo your $query to see if it is coming out correctly, before even trying to mess with mysql_query()? I think you should be able to see the problem from there.

Re: [PHP] Declaring vars as INT ?
Hello,
you could treat your variable as a string, and use the is_numeric()
function (but this will include floats, too). To answer your question
precisely and accurately, you may have to do regex matching since you
are out of the bounds of int.
However, why, *exactly*, are you trying to confirm that your string
is an integer? It seems to me kind of cumbersome and unnecessary. If
you provide more explicit information on what you are trying to do,
your overarching goal for the script, including what are your inputs
and intended outputs, along with some real code, we can probably find
a solution that will do what you want without mucking about like
this. Just my two cents.

Re: [PHP] Funky array question
Hello,
what have you been trying for comparison so far that has not been
working?
if you have php 5, you would want to use stripos, which is case-
INsensitive, not strpos, which is the opposite.
Also, note the warning on the man page. you would want to use a
triple equals sign !===false because stripos could return a zero or
an empty string which is actually ==false.
http://www.php.net/stripos/
if you do not have php 5, i would use regex so you can get case
insensitivity.

Re: [PHP] Funky array question
sorry, I am mistaken here. I forgot that !== is the same functionality as a ===, in that the comparison is made by value *and* type.

Re: [PHP] Funky array question
one more thing... if you have php 5 and = 3.0.6, you could use
stristr for case insensitive comparison without having to deal with
the slower and more cumbersome regex.

Re: [PHP] why does this not work?
javascript is a client-side language, while php is a server-side
language... the value you are passing to $width only exists on the
client side, therefore the php server-side boolean fails.
i think you will have to pass the client-side calculated variable of
screen.width to the php server before you can do this properly,
probably through a POST form or GET request. nice idea, though
(dynamically loading css based on screen resolution).

echo $width;

Re: [PHP] Easy question - delete strings from the beginning of space...
to get rid of potential double spaces after the explode, you could do:
foreach ($words as $word) {
if (!empty($word)) {
$first = $word;
break;
}
}
echo $first;
This will always return the first word.

(PHP 4, PHP 5)
array_pop -- Pop the element off the end of array
Description
mixed array_pop ( array array )
array_pop() pops and returns the last value of the array, shortening
the array by one element. If array is empty (or is not an array),
NULL will be returned.
Note: This function will reset() the array pointer after use.
Example 1. array_pop() example
?php
$stack = array(orange, banana, apple, raspberry);
$fruit = array_pop($stack);
print_r($stack);

After this, $stack will have only 3 elements:

[0] = orange
[1] = banana
[2] = apple
)
and raspberry will be assigned to $fruit.

I meant to give a valid example of when you can't pass the return
value from
a function to another function due to the fact that a reference is
expected
and in some situation the var you are passing is a reference to
'nothing' -
which works in older version of php but is also the cause of a
couple of
weird/nasty inexplicable potential seg faults ... it was fixed,

give a shit

Re: [PHP] Deny access from certain hosts
if people are allowed to post copyrighted images to your bulletin board, shouldn't you have some sort of password protection anyway? negating that, i would do it with PHP and not Apache. rather than simply serving up the file raw: img src=image.gif why not setup a php script to do URL referring blocking: img src=getFile.php?img=image.gif in the getFile.php file, you could check the referring URL, and then present the file, or not. you would need to move the images out of the web tree, though, so people couldn't bypass your script. it sounds like you need to reconsider what you really want, though.

$RFC_formatted = date('r', strtotime($timestamp));
done!

Re: [PHP] Sessions , expiry times and different time zones
As I said, **rather** than relying on cookie expiration. This *necessarily* means that you will need to set the cookie expiration to sometime way in the future, like next year (or more dynamically, use the date() and mktime() functions to always set the cookie expiration to + 1 yr from today). If you do this, you will have no chance of the cookie itself expiring; therefore you can rely solely on the $_SESSION variable. The cookie will contain the session id that the webserver will be able to use to repopulate the $_SESSION variable as long as $_SESSION['expiration'] is still in the future. If $_SESSION['expiration'] is in the past (or is empty) and you issue a session_destroy() and a setcookie(), the cookie can be destroyed, too. I have written something similar to this in the past, and it behaves exactly as you would like and expect. Another benefit is that this is more secure than relying on a cookie-supplied expiration time. Jordan On Sep 6, 2005, at 8:51 PM, Dan Rossi wrote: client cookie expires hence no more session ...

Re: [PHP] Better timestamp explanation to the client
methinks you should convert the datetime to a unix timestamp with
strtotime(). then you can compare the difference between this
timestamp and a unix timestamp of now to find if you have logged in
within a min. of the previous time. Then, once you know what text to
display (e.g. Less than a minute ago!), you can format the original
datetime timestamp with the date() function to be however you like.
You may have to read the manuals for all three of these functions
several times. good luck!
actually, you may be able to do simple operators (e.g. , , or -)
with the datetime as is, without having to convert to a unix
timestamp. NOW in datetime format can be gotten with:
$now = date('Y-m-d H:i:s');
i'm not sure though. just try it!

Re: [PHP] Assign values in foreach-loop
Hello,
You simply need the $key variable, then you can set a new value for
$arr[$key] for each array element:
?php
$arr = array(1, 2, 3, 4);
foreach ($arr as $key = $value) {
$arr[$key] = $value * 2;
}
// $arr is now array(2, 4, 6, 8)
?
http://www.php.net/foreach
If you have PHP 5, you can perhaps more efficiently do this:
As of PHP 5, you can easily modify array's elements by preceding
$value with . This will assign reference instead of copying the
value.
?php
$arr = array(1, 2, 3, 4);
foreach ($arr as $value) {
$value = $value * 2;
}
// $arr is now array(2, 4, 6, 8)

I think $arr1 is only a temp-var, so the assignment won't reflect

Surely I can do it with a for-loop, but those arrays are a bit
complex and a foreach would be much easier to read.

Re: [PHP] Help: Get the value of pi up to 200+ digits?
http://us3.php.net/manual/en/ini.core.php#ini.precision
precision sets the number of significant digits, *NOT* the number of

If you want to get pi out to 16 decimal places you need a precision
of *17* because the beginning 3 is a significant digit.
Your code does exactly this, displaying pi with 15 decimal places.

Re: [PHP] running process in the background
Oh wait... you are not specifying your $_POST variable. you need to
use the key for $_POST. just do a print_r($_POST) to find the key
from the $_POST array that you are looking for. also, i would not
pass a $_POST variable directly to your shell without escaping it
somehow, first...

Did you try also sending stderr to /dev/null rather than stdout only?
I think the syntax is to add a 21:
foreach ($_POST as $kid){
`php run.php param1 param2 /dev/null 21 `;
}
This should put each process in the background and suppress all
errors and output. Does that work?

Re: [PHP] Problem with SimpleXML
Yes, simplexml can do this easily. See:
http://www.php.net/simplexml
Example 7. Setting values
Data in SimpleXML doesn't have to be constant. The object allows
for manipulation of all of its elements.
?php
include 'example.php';
$xml = simplexml_load_string($xmlstr);
$xml-movie[0]-characters-character[0]-name = 'Miss Coder';
echo $xml-asXML();
?
The above code will output a new XML document, just like the
original, except that the new XML will change Ms. Coder to Miss Coder.
Uros, it looks like you want to change one of the attributes; you
will need to use some of this code to handle the attributes:
Example 4. Using attributes
So far, we have only covered the work of reading element names and
their values. SimpleXML can also access element attributes. Access
attributes of an element just as you would elements of an array.
?php
include 'example.php';
$xml = simplexml_load_string($xmlstr);
/* Access the rating nodes of the first movie.
* Output the rating scale, too. */
foreach ($xml-movie[0]-rating as $rating) {
switch((string) $rating['type']) { // Get attributes as element
indices
case 'thumbs':
echo $rating, ' thumbs up';
break;
case 'stars':
echo $rating, ' stars';
break;
}
}
?

[PHP] syntax for two comparison operators
General question,
Is there a technical reason why PHP does not allow comparison
operator expressions like the following:
if (2 $x = 4) {}
I prefer this concise way as it is common for mathematics
expressions, and much easier to grasp physically on first glance.
From what I can tell, this expression can currently only be written as:
if ( $x 2 $x = 4) {}
Would adding this syntax to PHP be incredibly difficult or lead to
performance slowdowns?
I think I remember reading that PHP always evaluates expressions from
right to left, so I guess there may be a considerable codebase change
required. Maybe there could be a default function workaround for this
or some other way to automagically process these more concise
expressions without too much of a slowdown?? Just curious.

Is there a good tutorial out there (I can't seem to find it) on how to send HTML to a browser where the HTML includes IMG tags with links to image files? If I need to set up the filepaths with variables I can figure that out, but not sure what functions to use to set the paths up. You need to use absolute URLs for the images. Still, some mail programs and webmail sites disable remote image displaying by default as images may be beacons to spy on users. ALternatively you can embeded images in the actual HTML messages and they always display properly. That is done with MIME multipart/ related messages. You may want to take a look at this MIME message class that can be used to compose messages with embedded images.

Re: [PHP] PHP MySQL insert
besides just escaping your strings, i think you are having a quoting error: http://www.php.net/manual/en/language.types.string.php Commas should not have to be escaped, and indeed the mysql_real_escape_string() function will not escape commas. After escaping your input data with this function, I would make the $query text a bit more technically correct: Change this: $query = insert into testtable6 (indx, col1, col2) values (NULL, '$data1', '$data2'); to this: $query = insert into testtable6 (indx, col1, col2) values (NULL, '. $data1.', '.$data2.'); echo $query.br\n; to ensure proper handling of all data in the sql commands. If you echo your $query before the insert, what do you get? This is always a good practice when you're having trouble.

Re: [PHP] Re: PHP 5 limits readfile to 1.9 MB?
Catalin,
Wow, that worked great, thanks.
I'm curious why you set a static buffer of 1024768... why not just do
filesize($file), as shown at http://www.php.net/fread ? Is it better
for memory usage to have a potentially smaller buffer? Also, you may
want an fclose($fp) after the file has been downloaded.
So is this a bug in PHP 5 or are they just purposely limiting the
abilities of the readfile command?

Re: [PHP] optional argument when creating a function
apparently the ampersand means to treat $link as a reference, not as
an optional argument:
http://www.softwareprojects.org/php-functions-12.htm
I think the way to do it would be to set a default value in your
function so that if a value is set by the calling statement that
would override it:
function doEmail($username, $link = false)
{
if ($link !=== false)
{
// doEmail($arg1, $arg2); gets sent here
print $link $username;
}
else
{
// doEmail($arg1); gets sent here
print $username;
}
}
haven't tested this, but give it a try.

Re: [PHP] mail()
Did you install sendmail? http://www.php.net/mail Requirements For the Mail functions to be available, PHP must have access to the sendmail binary on your system during compile time. If you use another mail program, such as qmail or postfix, be sure to use the appropriate sendmail wrappers that come with them. PHP will first look for sendmail in your PATH, and then in the following: /usr/bin:/ usr/sbin:/usr/etc:/etc:/usr/ucblib:/usr/lib. It's highly recommended to have sendmail available from your PATH. Also, the user that compiled PHP must have permission to access the sendmail binary.

what you need is the value in the HTML form to be the text you want

Re: [PHP] Help correcting a form mailer problem...
Ted,
On your sticky page, your checkbox input commands no longer have
their corresponding value attributes. Just add those back in, and
you will be all set (you only have the value attribute set on the
event_reg.php page, NOT on the event_reg_calc.php page). This is your
only problem.
i.e. change the code so that the output here:
http://www.passeycorp.com/event_reg_calc.php
will change from this:
input name=gmev[] type=checkbox id=gmev checked=checked/
to this:
input name=gmev[] type=checkbox id=gmev value=September 9th
checked=checked/

Subject: Re: [PHP] Help correcting a form mailer problem...
thanks for the reply...
after using the print_r($_POST['gmev']); and selecting all the
checkboxes to
send to the form
the return is Array ( [0] = on [1] = on [2] = on [3] = on ). So
the
values are missing.
don't really know how to proceed at this point.
any help is appreciated.

I would first start out by dumping the values of $_POST['gmev'] by
using
print_r($_POST['gmev']);
Sounds to me like you're not getting the data that your expecting
from the form for some reason. Maybe $_POST['gmev'] is an array of
null values?
-Good Luck

I previously built a sticky form with dynamic checkbox

The form works beautifully thanks to help from Jochem Mass and

I now have a slightly different problem...I have built an email
form to send
the form data.
I copied and used the following code which works great in the
sticky
form.
if (isset($_POST['gmev']) is_array($_POST['gmev'])) {
foreach ($_POST['gmev'] as $gmev_day) {
print pYou have registered for the: b$gmev_day/b Good
Morning East
Valley Event./p;
}
} else {
print 'You are not registered for any events!';
}
The results is this:
You have registered for the: September 9th Good
Morning
East
Valley Event.
Now when I use the same code modified for the form mailer I am
getting this
result.
if (isset($_POST['gmev']) is_array($_POST['gmev'])) {
foreach ($_POST['gmev'] as $gmev_day) {
$msg .= You have registered for the: $gmev_day Good Morning
East
Valley
Event.\n;
}
} else {
$mgs .= You are not registered for any events!;
}
result is - You have registered for the: on Good
Morning
East
Valley Event.
I am missing the value of the variable even though I am receiving
all the
instances of the variables from the checkboxes. When they are
selected, they
are present.
I really don't know what to do about correcting the problem. Any
guidance
here would really be appreciatedand...go easy on me...I am new
to PHP
Thanks before hand...

Re: [PHP] sending HTML (incl. embedded images) to browser
Hi Jake, You don't have to do anything special, you just have to have standards compliant HTML output. What is the HTML for the IMG tag output to the browser (i.e. go to the web browser, load the page in question, find the img tag, and send us this text). I think maybe your images are just not in the right directory or are not being referenced correctly. also, what is the actual PHP code used to print the img tag? maybe you're not escaping quotes correctly...?

[PHP] PHP 5 limits readfile to 1.9 MB?
Hello all, I am new to this list and I have searched the archives to no avail. I am having a peculiar problem when upgrading to PHP 5: My downloads are now limited to the first 1.9 MB of the file in question, with the download either terminating at 1.9 MB or seemingly continuously stuck in a downloading process at 1.9 MB. The code in the PHP script has not changed and all parameters that I could find that are relevant to this problem are given below: the minimal code needed for download: // $file_to_read is the complete path of the file to download header(Content-Type: application/pdf); header( Content-Disposition: inline; filename=\$filename\); $len = filesize($file_to_read); header(Content-Length: $len); @readfile($file_to_read); php.ini file for both php version 4 and 5 contain the following settings that may be relevant: allow_url_fopen = On max_execution_time = 300 ; Maximum execution time of each script, in seconds max_input_time = 300; Maximum amount of time each script may spend parsing request data memory_limit = 8M ; Maximum amount of memory a script may consume (8MB) post_max_size = 200M upload_max_filesize = 200M Some additional details: All files less than 1.9 MB download fine It is not a corrupted file, because all files larger than 1.9 MB fail after 1.9 MB The connection is not timing out (download of 1.9 MB takes only ~15 sec) Mac OS X 10.3.9 with Marc Liyanage's PHP 5.0.4 Fails for both Safari and Firefox Fails regardless of inline or attachment Fails regardless of pdf or ppt content-type This PHP code ALWAYS works for Marc Liyanage's PHP 4.3.4 with the same settings, above What am I doing wrong???

Hi Matt,
try this:

strtotime possibly will not work if your date is 01/01/1970.

Re: [PHP] Code Review PLEASE !!!
Wells first of all, you are going to want better form input validation.
For Example:
foreach ($_POST['fleet_id'] as $key = $value) {
$fleetCode = $_POST['fleet_code'][$key];
$historyUrl = $_POST['history_url'][$key];
$downloadUrl = $_POST['download_url'][$key];
mysql_query(UPDATE imp_fleet SET fleet_code = '$fleetCode', history_url =
'$historyUrl', download_url = '$downloadUrl' WHERE fleet_id = $value) or die
(mysql_error());
}
Are you sure that $_POST['fleet_id'] is valid? or even a number?
What happens with $_POST['fleet_id'] == '1 = 1'?? Well, long story
short, imp_fleet has no more records.
Just a simple example of a huge problem.

Re: [PHP] Code Review PLEASE !!!
If it were me I would do both Client and Server side validation.
The majority of the time the client side will suffice, but, simply put,
because you don't/may not look at the HTML source of a web page, doesn't
mean that nobody else does.
The fact of the matter is, you should not trust any data that comes from
a form. Even if the ids come from the database, you still want to
ensure that they really are a valid numerical value or whatever your ids
happen to be based upon.

Matthew Oatham wrote:
Yes I agree I need some validation, dunno whether to do server or client

as this is retrieved from the database where the field is an int.

Hello Guys,
I need a little bit of help with recursion. I've searched our PHP website
and Google, but none helped me understand my problem. There is a code below
this message in order to help you understand what I am trying to achieve.
Here is an explaination:
What I'm trying to do is list a typical category/subcategory system with
parents and children associated with those parents. My database table
(categories) lists all the parents and children together, each with a
parent_id field
(with root being a value of 0). What I want to do is, if a user clicked on
one of the parent categories, only one level of that category will show (or
only the direct children of that specific category will show). I want the
depth to be endless because I want to control the depth some other way. I
know that using a recursive theory would cost a lot as far as speed goes,
but I'm willing to risk it for now.
Here is the problem: The problem is that the recursive method yields several
arrays, instead of one long array. I tried to use an array_push() function,
but that doesn't seem to work well with multi-dimentional arrays. I tried
the straight way, i.e. $menu_array[$count]['name'] = $name_of_category or
$menu_array['name'][$count] = $name_of_category, but that yields several
arrays instead of one long array or category names. The depth of the
categories can be determined by the $_GET string passed, $_GET['some_path'],
which is in the format: parent1_child1_grandchild1_grandchild2,
etc.($some_path = 1_4_6_8), where all of these are related to each other.
These, of course, are split using the underscore delimeter: $path['0'] = 1,
$path['1'] = 4, and so on.
And finally, here is my question: How do I get all these categories, parents
and children, listed into one array and then returned. I want to be able to
list them on the web page using one array. I will also include id,
parent_id, and other info with each array, but first I want to get the name
listings of the categories to work. Also, if anyone has any suggestions
about a more speedier way to do this, please let me know.
Sorry for the long explaination, I just wanted to make sure you guys
understood my goals. Thanks in advance to anyone that responds, I appreciate
it very much. Here is the code I promised:
-
function menu_tree($parent_id = '0', $cPath = '', $menu_array = '') {
if (!is_array($menu_array)) {
$menu_array = array();
$cPath = $this-separatePath($_GET['cPath']); // separates $_GET
string into array of category ids
} else {
reset($cPath);
array_shift($cPath);
}
if (sizeof($cPath) = 0) {
$db = new base_db();
$query = select cid, name, parent_id from categories where
parent_id = ' . $parent_id . ' order by sort_order, name;;
$categories = $db-fetch_results($query);
//echo sizeof($cPath).br /;
//echo $query.br /;
for ($i = 0, $count = 0; $i count($categories); $i++, $count++) {
// The following are the methods I tied, but failed to work
//$menu_array['name'][$count] = $categories[$i]['name'];
//$menu_array[]['name'] = $categories[$i]['name'];
//$menu_array['name'][] = $categories[$i]['name'];
//array_push($menu_array, $categories[$i]['name']); // This one works,
but
does not yeild a multi-dimensional array, which is what I need if I were to
add more information to the output of this array, like id and parent_id
//array_push($menu_array[$count]['name'],
$categories[$i]['name']); // This does not work, gives error saying the
first parameter of array_push must be an array
if (($this-get_children($categories[$i]['cid']))
in_array($categories[$i]['cid'],$cPath)) {
$this-menu_tree($categories[$i]['cid'], $cPath,
$menu_array);
}
}
}
print_r($menu_array);
}
-
Here is what it returns using the print_r() function on $menu_array
Array ( [name] = Array
(
[0] = Cars
[1] = Honda
[2] = Accord
[3] = 1996
[4] = 1997

You can pass it in the function as a variable.
