So, if I understand correct mysql_real_escape_string is the way to prevent
sql injection.
Is there still need (as in both good coding and security) for variable
validation at that point? Like a hidden field id that must only be an int?

I don't think so. What if magic_quotes_gpc gets turned off or you move to
another environment. Best practice is to turn if off (if you can) and so
gain fine control over your data. You can either compromise and use a
function that checks whether the setting is enabled and either add your own
slashes or do nothing. To ensure the best level of control over escaping
data before it goes into your db, check out mysql_real_escape_string.

With magic_quotes_gpc or addslashes it's harder to do injection attacks
but it's still possible. http://shiflett.org/archive/184 demonstrates
an attack using php and mysql with multi-byte characters.
I think the more likely attack is actually due to how annoying
magic_quotes is. You have to remove it to do any work, then you have to
remember to put it back on because you aren't escaping your sql.
A final point is that it looks like magic_quotes will be removed from PHP6.

What exactly do you mean by ' You have to remove it to do any work '?
Seems that the only and best way to prevent mysql injection is the
combination of mysql_real_escape_string combined with value validation.

Yes, this should be what you use. When you think about application
design, not only should you escape the data going into the database for
security purposes. DBMS's have certain characters specific to them that
can make the DMBS think what's been inputted as a quote, but PHP won't
see it as a quote, and magic_quotes, addslashes, etc. won't catch it -
still leaving a security hole.
You should also be making sure you're inserting the proper data (ints in
integer fields, strings in varchar, char, text, etc. fields) so that
your DBMS doesn't start spitting SQL errors out in a log (or worse yet -
to your visitor) and cause nightmares for visitors entering seemingly
valid data when they aren't. This is definitely done in the case where
you don't have quotes around your data in the SQL query - as is done
sometimes with integer, double, etc.
Easy validation for integer:
is_numeric($_POST['var'])
Easy way to just straight-up typecast:
$clean['var'] = (int) $_POST['var'];
The best way is to check to see if it is_numeric rather than force it's
type to be integer - but for simplicities sake, it can be used.

As noted, that's a javascript question. However your PHP code is
vulnerable to XSS attacks; you should at least encode the output with
htmlspecialchars() so that URLs like
"foo.php/<script>alert('hi');</script>" are safe.
eg. <?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>

Oh, I wanted to call a php function on my page that changes some CSS. I
was hoping I could change my CSS on the fly without having to reload
page... but after doing more research, I think that a page refresh is
best way to go.
All the Ajax/PHP examples i have seen deal with elements on page (in
this case i have PHP script in head that changes my css)... Still new to
"Ajax" and XMLHTTP... I know how to handle JS, but I am way more
comfortable with PHP. Not too many examps on the web that show some good
techniques for calling PHP functions to manipulate CSS that I could find.
I am also not a big fan of plugging-in a huge Ajax scripting
library(ies) for something as simple as calling a PHP script to
manipulate CSS. I would prefer simple on the JS end of things and make
it more about PHP without a page refresh. :D
Lol, hope that makes sense... In a bit of a rush - headed out door to
work. :)
You guys are right though, I should probably ask on the JS listserv.
Many thanks for your time.

hi, it's strip_tags and only removes the tags (<a href ...) but keeps
the plain text that would be displayed in a text browser.

Hi there,
thank you for the hint. This it the one I was searching for. However
unfortunatelly the function also strips all other tags! I am looking for
one that only does strip the <a href tag.
I am not so familar with regex, but I fear I would need to :-(
My guess is that it must be something like this:
$str = 'foo <a href="">test</a> o';
$str = preg_replace('<a (.*)', '', $str);
echo $str;
Can anybody help me on that? Thank you so much in advance.

Merlin

Two things:
First, you can actually specify which tags you don't want strip_tags to
take out. Say for example you want <p> and <br /> tags to remain in the
string:
$string = strip_tags($string, '<p><br />');
Second, don't forget the tags you'll need in the preg_replace function:
$str = preg_replace('/\<a href="([^\"]*)"[^\>]*\>/', "\1", $str);
You can use other characters, such as ! if you want instead of /, but
you have to use the same at the beginning and the end.

This seems to be a hair faster. I extended the test to 10000 requests
(still concurrency 10) to make the test a little more reproducible:
echo str,var,str did 604.65 requests a second where <tr><td><?= $x
?></td></tr> did 599.63 requests a second. I also tried echo str . var .
str, and it came in at about 584.55 requests a second. printf("str %i
str",var) came out at 547.01 requests a second and printf("str %s
str",var) was only 452.03 requests a second.

Approximately 330 (?!) requests a second for that one.

I'm not sure that my results would count as contradictory - I'm running
APC which would likely throw performance related numbers out of whack as
compared to out-of-the-box PHP.
Because of that, I wouldn't recommend anyone take my numbers too
seriously - they're just an example taken from my server: 1.8 GHz
SMP/1G/RAID5/Linux 2.6.17.7/Apache 2.2.3/PHP 5.1.6/APC 3.0.12p2. Anyone
else's results would probably vary widely.

Which begs the question, does it make much of a difference? (not you
being bored, but the rather speed concers).
With all the things out there that can slow your browsers reaction
time in presenting some result, does a couple of seconds count much
in the over all scheme of things?
I know, purest will say that they want to make whatever they do as
fast as possible, but is that time to make it faster be better spent
elsewhere? We used to have to worry about the size of our strings,
but now we can place the kjv of the bible in one. So, what's the
point of counting characters in strings now?
I suspect at some point, probably soon, speed isn't going to matter much.
Opinions?

There seems to be one thing rarely anybody remembers, echo admits multiple

Done, but again it doesn't seem to make any significant difference to
the performance.

I would have to agree. Having watched the server CPU load while playing
with this test script it would appear that the performance can be
skewed a lot more by that than by the method you use for squidging out
the output.
As a curiosity I've also added a test using <?php print $x; ?> and
bizarrely that appears to be slightly faster than <?=$x?>.
Weird.

I would have been surprised if an opcode cache had made a huge
difference. I don't think the Zend Engine is intelligent enough to
compile the various different tests to the same set of opcodes - but I
could be wrong. I'm still quite new to the PHP internals.

As I said in another post, the performance varies wildly with the load
on the server.

When I run those tests locally, the numbers are totally different and the
performance of one over the other comes out far clearer. I can only assume
that the numbers in the test run in a remote server are so much influenced
by the ability of the server to push out the characters into the output
stream that the processing time itself is of very little relevance. This
table shows the numbers for the different tests as run on my machine,
locally (where output streaming is irrelevant) and run from your site:
Using <?=$x?> Took 0.2801 seconds Took
3.5937 seconds
Using <?php print $x; ?> Took 0.3286 seconds Took 5.2654 seconds
Using line-by-line single-quoted print: Took 0.1215 seconds Took
3.2256 seconds
Using line-by-line single-quoted echo
with comma separated arguments Took 0.2542 seconds Took 3.2220
seconds
Using line-by-line double-quoted print Took 0.1782 seconds Took
3.3129 seconds
Using buffered single-quoted print Took 0.0277 seconds Took 3.3077
seconds
Using buffered double-quoted print Took 0.2038 seconds Took 3.3012
seconds
It would seem that it takes about 3 seconds to push those bytes into the
network, the actual processing times get completely masked behind a simple
glitch in the throughput of the communication line. While the differences
on the rightmost column (except for the second one, which is way off) are no
more than 5%, in the middle column the differences are up to 10 to 1. But
then there is that second row, which is so much higher and it is so in both
columns.
Unfortunately, I cannot make much sense about all this. I don't get it.
Nevertheless, something it is clear is that buffering all the output first
and then pushing it out all at once seems to beat them all, specially using
single quoted strings. Run locally, the differences are amazing!

My guess would be that it's in the interpreter -- the look-up for
"<?" as compared to "<?php" may be delayed because of checking for
the short-tag option-on, or something similar. But, I admittedly
don't know.
However, I strongly suspect that drawing to the screen will take
longer than executing any "=" or "print" statement anyway. So
regardless of the time saved in computation, the delivery would
appear identical. It reminds me of the "hurry-up and wait" saying we
had in the Army some 50 years back.

Its jpg. Look... I don't know exactly what your point, I'm just asking you about the function to resolve the size of image like the
codes below:
if (file_exists($img_path)){
list($width,$height) = getimagesizes($img_path);
}else{
$width = $ height = $max_size;
}
So is there any other option to replace file_exists();?

It's a RS232 serial register. PHP, running at the server side, could

You might also consider MySQL functions for this -- there's many of

Just realized I forgot to CC: the original list on my reply below.
I also have since realized that using the solution in my reply below,
the SERVER *COULD* cause the register to open. On the server side, a
script that connects to HTTP://ip-of-register-to-open:secret-portnum
would cause the register to open as desired.
So, this is just a simple modification of my original reply. You still
write a socket listener app. that runs on the workstation where the
register is connected, that is capable of opening the register on
demand. Then, when the user using the browser does something to open
the cash drawer, you run a script on the server that connects to
REMOTE_ADDRESS:secret-port which makes the "listener" app. open the cash
drawer. (Okay, so it's technically client based, but server driven.)
A similar tool (the same listener app, even) could be used to send text
to the workstation-attached receipt printer. It could be setup such
that any text received on the port it's listening to, is simply echoed
to the printer. So, now the server generates what needs sent to the
printer and prints it by connecting (from the server) to the listener
app., followed by a connection to the port that causes the drawer to open.

I think I'd be tempted to write a simple socket listener app., that
could listen on a TCP/IP port and when it makes a connection (and
optionally gets the right command), could open the register.
There are lots of examples of socket listener apps. done in Perl (check
Google), but the local app. would *not need* to be in Perl (that's just
one I've used personally).
Once the app. is running, simply connecting to
http://localhost:secret-portnum *could* be enough to make the app. open
the register (by sending the right command to the serial port).
Using this technique, any HTML that references
http://localhost:secret-portnum would open the register, regardless of
how the HTML is generated.

I guess that embedding an ActiveX object to open the drawer into the web
page would be the easiest option for the application programmers to handle.
It would give the added flexibility to use JavaScript on the client side to
call the object method to open the drawer, besides sending the page with the
object embedded and the property to open the drawer set to open. Besides,
it would be easier to mantain since it is obvious which cash register you
are talking about, the one physically attached, otherwise, you would have to
mantain a table of which cash register corresponds to which client.

Is it always in that format?
preg_match ( "/&friendID=(\d{5,})&/", $source, $id );
The result will be in $id[1].

Keep in mind that if the ID is less than 5 digits, it won't match (I

That depends on if you reset the cookie when they come back or not. If
your routines set the cookie only if the cookie does not already exist,
then it would not reset the cookie at 25 days, so it would indeed expire
5 days after that.
If you check to see if the cookie exists first, and then reset the
expiration date at that time, then the cookie would last for another 30
days...

There are several things you need to check for, and probably add to your
emails that you're sending.
Number one, add additional headers to make SPAM / Bulk filters realize
the message is not SPAM or should not be considered SPAM. IE:
$headers = "From: Suresh Kumar <myemailhost.net>\r\n".
"X-Mailer: PHP 4.3.2\r\n".
"X-Sender: $_SERVER['HTTP_HOST']\r\n".
"X-Comment: If you can put a comment here, do it.\r\n";
mail($to, $subject, $body, $headers);
The above is considering you have already declared the $to, $subject,
and $body variables. Also, make sure your $subject is not
'undisclosed-recipients;' or something like that - it's a big no-no and
will definitely flag some SPAM filters. Put a valid e-mail address - but
you can still use the BCC-headers and everything should go just fine.
Alternatively, if your list is not too large, it looks better to run a
for / while loop to send each recipient a message directly (ie: not
using BCC) as that will cut down on the SPAM probability.
Second, if you are making MIME emails, make sure you are doing so
correctly. You can learn about creating multipart/alternative MIME
emails more at www.php.net/mail.
Finally, if none of the above works, it would be helpful for us to see
the headers of the received message from one of your recipients where
the message was put in the BULK folder.

For future reference it is best you provide a full code example in
what your problem is when you ask the question, Asking if it something
is proper isn't going to get you far.
<?php echo $am_somevar; ?>
is perfectly valid but accoring to the mistake you had you should have
been using:
<?php echo $I_am_somevar;?>
It would have been more relevant to supply the problem along with the solution.

No problems at all. I just noticed that the question you originally
proposed couldn't really be solved without more info other wise
everyone would be guessing at what the issue is.. And in the end you
solved your own problem.
It is a common thing to do such a thing, i tend to practice this
method of posting questions to ensure i provide enough information to
solve the issue:
1) compose a question
2) forget the question was about and read the question, and see if
it is even able to be solved.
3) if it cant be solved, include a statement like: I've been looking
over this and can't see what I'm missing (type of thing).

Hello,
I would appreciate your help. I am trying to get php and apache work
together and have a strange error while starting apache:
Can't locate API module structure `php4_module' in file
/usr/local/libexec/apache2/libphp5.so: Undefined symbol "php4_module"
I am using PHP 5.1.6 (cli) and Apache/2.0.59 on a FreeBSD 6.1 stable
release. Could anyone offer any suggestion why php4_module is missing in
libphp5.so?
Many thanks!

Thanks for such a fast response. I used portinstall. I did have apache
1.3.37 at the beginning but it later turned out that for some reason I
will have to upgrade for apache 2.x so I ran pkg_delete and the went for
apache2.
I am quite new to FreeBSD but the machine is not online and I want to test
and learn. I need these to working as I am running/testing/learning exim
and plan to use vexim in future. Probably irrelevant here but I am willing
to provide output.
Here is the content of php5 options:
_OPTIONS_READ=php5-5.1.6
WITH_CLI=true
WITH_CGI=true
WITH_APACHE=true
WITHOUT_DEBUG=true
WITHOUT_SUHOSIN=true
WITH_MULTIBYTE=true
WITH_IPV6=true
WITH_REDIRECT=true
WITH_DISCARD=true
WITH_FASTCGI=true
WITH_PATHINFO=true
Many thanks for your help!

This is where port understanding comes in handy, I avoid port
installation of my server level of applications (php/apache/db).
If I understand correctly you first did a portinstall to get
apache/php4 installed and then did a pkg_delete to remove those old
versions and then added portinstall php5. What seems to be happening
is that you have an apache version that is trying to load php4 but
php5 is installed and thus the error. There are two options i think
will help:
1) start over
2) ensure there arn't any current port issues (via the bsd port mailing list)
Or
1) install php/apache/(db) manually and manage updates yourself.
What ever is the case it is obvious that you have conflicting
(configuration/installation)'s.
You might also want to try some bsp-port resources on searching for
what is going wrong.
HTH,
Curt.

OK. Thanks! I did try to start over by deleting php5 and issuing make,
make install and make clean. However, the result was just the same.
I need to go to BSD lists to find out how to completely wipe out PHP from
the system so that there is no trace of it left. Would that be a good
solution for a newbie in *nix systems in general?
Thanks again. I really appreciate that you are devoting so much of your
time to help me!
Warm regards,

Hi,
Please, please forgive! How dumb a person (me!) can sometimes be....!
I looked at httpd.conf again and saw that instead of replacing php4.so
library object I added a new line with php5 entry...
Sorry to have bothered!
Thanks!

I don't know about big and ugly, it seems more clear on what is going
on in this situation. But yeah it is best to clearify the switch as
you rewrote it.

Hello all,
I don't really get it to work with that functions from http://www.php.net/manual/en/ref.dom.php
I try to get the content of <td> fields on an external html page, where I just know some ids of the rows.
Example:
...
<tr id = 'tr01'>
<td>1</td><td>2</td><td>3</td><td>4</td>
</tr>
<tr id = 'tr02'>
<td>1</td><td>2</td><td>3</td><td>4</td>
</tr>
<tr id = 'tr01'>
<td>1</td><td>2</td><td>3</td><td>4</td>
</tr>
<tr id = 'tr02'>
<td>1</td><td>2</td><td>3</td><td>4</td>
</tr>
...
PS: Please note, that id is written more than once. So DomDocument->getElementById('tr01') returns only one element and not two or more...
I can't find out how to grab the data in the td fields... I don't find examples to look at... :-(
I'd be really glad if somebody could give me some advice or tutorial websites about that...
Thanks a lot

To start with, an ID should never be repeated. A name can be repeated, an
ID shouldn't. That is why there is a function to get an array of elements
with a certain name but there is none to get a list of elements with the
same ID simply because there shouldn't be any. Something helpful in
traversing the DOM is any tool that gives you a good view of the tree
structure. One such comes already in the Firefox browser.

Unfortunately, I have no way to modify the source html page, it's on the web.
By the way, because I found it strange to have more than one field with the same id, I looked on the famous selfhtml tutorial website http://de.selfhtml.org which says that unique id is only mandatory for css, but not for javascript actually. I was surprised...
http://de.selfhtml.org/css/formate/zentrale.htm#individualformate
http://en.selfhtml.org/css/formate/zentrale.htm#individualformate
(english translation is a little different)

The techs at Rackspace just enabled SOAP for me. I have a command:
$soap = new SoapClient('http://geocoder.us/dist/eg/clients/
GeoCoderPHP.wsdl');
which works fine on my PHP 5.1.6 development server, but it won't run
on my 4.3.9 server at Rackspace. The only place 'soap' appears in
phpinfo() is '--with-soap' up in the Configure Command section. There
is no Soap section further down on the page, as there is on my dev
server (which, I notice, says '--enable-soap' instead).
Is it possible that the Rackspace techs didn't do something right?
That would be a first indeed.
