Unfortunately, it might also confound someone who doesn't speak the language.
Admittedly, they would probably already be struggling with the rest of the
site...
I guess locale-dependent captchas are a possibility.

I'm not talking about language problems for the user to solve. This
question originally started by the op asking for solutions to human
spam, but most of what I've seen so far in the thread is all about how
to stop bots. By Linguistic analysis, I'm talking about passing the user
offered content through a filter to check for the probability that it is
spam. This goes beyond just looking for spammy words by looking at the
relationship between words, frequency of words, and much more. It's very
complex, but by the end of it, each post gets a rating value, which can
be used as part of a threshold to reach in order to have a post
automatically verified.
Thanks,
Ash

That won't do what the OP asked, it will just return a list of all the
functions defined, which could be a lot more than is actually being used
in a process, such as in the case of included libraries of functions.
Would some form of PHP debugger help here? I've not used any debuggers
before, but I would imagine that this is something which could be
achieved quite easily with one.
Thanks,
Ash

There's xdebug, as mentioned, that'll do it as an extension.

Single quotes need to be escaped if you are using them as part of a
query. For example:
$query = "UPDATE table SET title='This is a title with \"quoted\"
\'characters\''";
Note that here, double quotes are used to encapsulate the whole query
string (as it is generally preferred this way), the value of the title
field is encapsulated in single quotes. Lastly, where I've wanted double
quotes to be used in the query, I've escaped them with a back-slash.
This escapes them from PHP, as mysql is using single quotes, so directly
in the query they're fine. The single quotes are also escaped with
back-slashes, but this time to escape them from mysql, as single quotes
are used as the string delimiters there.

(Serious question. I don't know the mechanism by which they determine
what is and isn't a dynamic IP.)
I run my own mail server and use the zen blocklist from spamhaus.org.
The zen list combines all the the anti spam lists plus all IPs
designated to end users (http://www.spamhaus.org/zen/)
The reason for blocking end users is that a lot of SPAM is sent out by
compromised machines from some home Internet connection. I am currently
getting about 5 connections every 2 seconds from compromised computers
attempting to spam my server. The origin is usually a dynamically
assigned IP from Sprint or Comcast (USA ISPs).
So blocking the end users from sending SPAM tends to cut down on a LOT
of junk.
Here is a bit more info about the end user blocklist.

You are talking about two different mechanisms here. The black or grey
lists are services that track known open relays and other sources of
spam, viruses and assorted malware. Anyone can subscribe to them and use
them to validate relay requests.
There are also services that keep track of valid domain addresses and
the IP assigned to them. They are usually called DNS hosts. These can be
polled to identify the IP address for authorized domains and hosts.
There are even special records for the email severs within a domain.
Most dynamically allocated IP addresses will not show up on these
servers unless you have access to a service authorized to inject
records.
So basically, qmail did a DNS lookup on your host/domain name and did
not find a record pointing to your server. Therefore it rejected your
request.
You will have to ask your ISP for the address of their SMTP and POP
servers if you don't know them. But usually your email client is already
configured to talk to them. I would just go into my Thunderbird setup
and look up those addresses.

Hiya,
I know this isn't the best place to ask, but I figured enough people
here would have at some point installed PHP on some Linux variant, and
I'm hoping that some of you may have even done it on Fedora 11.
I'm using the built in gui package manager in Fedora (kpackagekit) to
install php, mysql and php-mysql. I let it resolve the dependencies and
install, but phpMyAdmin refuses to connect to the Mysql database with
the default username and password (root, no password) even though I can
successfully connect to plain old Mysql over the command line with
"mysql -u root -p"
I thought it was some problem with the built in repositories, so I
attempted to build PHP from source, and after sorting out the
dependencies manually, I got PHP installed and working from the command
line. However, when I try to start httpd up again, it gives me the
following error:
libphp5.so: undefined symbol: OnUpdateLong
I ran a nm command against the libphp5.so file, and the first line is "
U OnUpdateLong" (intentional spaces there)
Has anyone come across either of these problems and do you know of a way
to overcome either one? All I need really is a way to get it working, so
don't mind whether it's via the GUI or the command line!
Thanks,
Ash

Hi Ashey,
What version of PHP did you compile?
What were your ./configure options?
It looks like the php source is using OnUpdateLong but the source file
containing OnUpdateLong is not included or linked properly.
I have ran into this kind of problem before.

I've actually got some steps closer to figuring out the problem. It
seems that the connection between PHP and MySQL was fine, it just
refused a connection as root. If I create another user it connects via
phpMyAdmin just fine.
The thing now is figuring out either how to get it to connect as root
(it currently keeps refusing root) or create another user with all the
privileges of root so I can connect with that. As of yet I haven't been
able to figure out either!

Well, I'm not compiling from the source now, I went back to trying to
use the Fedora repositories (which was the only reason I ended up trying
to compile from source in the first place)

I'm looking for a regular expression to accomplish a specific task.
I'm hoping someone who's really good at regex patterns can lend a quick hand.
I need a regex pattern that will grab URLs out of HTML that have a
certain link text. (i.e. the word "Continue")
This is what I have so far but it does not work properly (If there are
other attributes in the <a> tag it returns them as part of the URL.)
preg_match_all('#<a[\s]+[^>]*href\s*=\s*([\"\']+)([^>]+?)(\1|>)>Continue</a>#i',
$html, $matches);
It needs to be able to extract the URL and disregard arbitrary
attributes in the HTML tag
Test it with the following examples:
<a href=/path/to/url.html>Continue</a>
<a href='/path/to/url.html'>Continue</a>
<a href="http://example.com/path/to/url.html"; class="link">Continue</a>
<a style="font-size: 12px" href="http://example.com/path/to/url.html";
onlick="someFunction('foo','bar')">Continue</a>
Please reply
Your help is much appreciated.
Thanks in advance,
Brad F.

Looking at this document from an XML standpoint, I could see doing this rather
easily. Without having to use regex. You might look into using DomDocument and
simpleXML to complete the task.

\"\']+?).+?>Continue</a>#i', $html, $matches);
I just changed your regex a bit. What your regex was previously doing
was matching everything from the first quote after the href= right up
until the first > it found, which would usually be the one that closes
the opening tag. You could make it a bit more intelligent if you wished
with backreferencing to make sure it matches against the same type of
quotation character it matched as the start of the href's value.

I appreciate the help. However, when try this I only get the first
character of the URL. Can you double check it please.
Thanks again

I think it's probably the first ? in ([^\"\']+?)
Remove that and it should do the trick

Hi Brad,
I agree with Jim.
Take a look at this. It might help.
<?php
$xml_string = <<<TEXT_BOUNDARY
<html>
<head>
<title></title>
</head>
<body>
<div>
<a href="http://example.com/path/to/urlA.html";>Continue</a>
<a href="http://example.com/path/to/url2.html";>Brad Fuller</a>
<a href="http://example.com/path/to/urlB.html";>Continue</a>
<a href="http://example.com/path/to/url4.html";>PHP.net</a>
<a href="http://example.com/path/to/urlC.html";
class="link">Continue</a>
<a style="font-size: 12px" href="
http://example.com/path/to/urlD.html";
onclick="someFunction('foo','bar')">Continue</a>
</div>
</body>
</html>
TEXT_BOUNDARY;
$xml = simplexml_load_string($xml_string);
$continue_hrefs = $xml->xpath("//a[text() = 'Continue']/@href");
print_r($continue_hrefs);
?>

That did the trick. Thanks Ash you are awesome!
Also thanks Jim for your suggestion. I may move to SimpleXML if the project
grows much bigger. But for now I was looking for a nice one liner and this
is it.
Cheers,
Brad

Hi PHPeople
I have an odd problem at my new work and wonder if it's some sort of odd
setup that is causing this problem when using sessions:
Like I said, my new work and odd setup, an include file had a
mysql_close() in the bottom
Speaking of mysql_close(), I think I've read somewhere that in PHP6 a db
connection will not be closed, when the script is done. Is this true?
Cause then it would definetly be best practice to to _always_ have a
mysql_close() in the end for the main file.
