Ok, it's not the regexp for detecting email addresses what I need,
that's widely published, thanks. I'm using ereg to match this regular
expression:
(On)[\s\w\d\W\S\D\n]*(wr[i|o]te[s]?:)
That will match phrases like
"On 8/3/05, Carol Swinehart <cshartgreenapple.edu> wrote:"
the type "On date, name <email> wrote or writes:"
The thing is I tried this regexp with Regex Coach and it matches fine,
but ereg returns no match
ereg($regexpstr, $str, $regs)
I know there are some comments at php.net about how ereg has some bugs,
any idea if this could be one?

Though I will agree with you to some extent, I've had quite a lot of
success with this, which is pretty thorough:
^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-
\/\=\?\^\`\{\|\}\~]+(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}
[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|
(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]
\d|25[0-5])\]))$

This may be slightly OT, but I've modified a gallery script that I had
written for me which reads directories and echos the dir name as a
gallery.
Unfortunately, it doesn't look very nice with say picsofsomething so I
renamed the folder 'pics of something'
When this is read, the string inserts %20 for the spaces, which is
fine, but are there any reasons why I shouldn't be doing this?

A while back, this would have been liable to cause problems in Netscape
(v3/4). I don't think it makes so much difference these days, but I just
avoid it out of habit. You can get a more readable effect wihout spaces by
using an underscore, say, in the directory name, and when you need to print
it to screen, replace the underscores with spaces

Wasn't the plus sign the replacement for a space? Pics+of+something is more
readable.

I believe %20 and + are used to replace spaces.

Hi Roger
KnowledgeTree comes highly recommended - our company was reviewing it,

you'd think someone had done this before - try google first - there are
1000's of scripts that do this, have a look at some and see how they do it.
e.g.: http://www.google.com/search?q=website+counter+script+php
or use your fingers - but that could get problematic if you get slashdotted. ;-)

Suma,
I am working on that now. I will soon have a script ready under GPL.
There are two versions, one with mysql and one with flat files. Do you

if you're only getting a value of 1 it is likely putting everything on a

When I open the list in notepad everything is on one line with a
square box character.
When I open it in wordpad, it's one email address on each line.
[/snip]
Sounds like that there are not any newline characters in the file. You
could do something like this...
$theFile = fopen("http://www.mysite.co.uk/mailing_list_database.list",
"r");
while(!feof($theFile)){
$theLine = fgets($theFile, 4096);
$theCount++;
}
fclose($theFile);
echo $theCount;
attached mail follows:
do this:
$file = 'http://www.mysite.co.uk/mailing_list_database.list';
echo '<pre>';
print_r($file);
echo '</pre>';
im pretty sure you'll only see 1 key..
if each has its own line, you would see something like:
Array
(
[0] => foo
[1] => foo
[2] => foo
[3] => foo
)
etc...

Are you running this php code in windows, where a line break is made up of
a carriage return and a line feed? The file was probably created on
unix/linux where the line break is just a line feed. If you try to read this
file in windows, it will think everything is on one line. You either have to
replace all line feeds with carriage return and then line feed, or read it
in and parse it.

Windows is \r\n; unix/linux \n; MAC \r. So the \n gets Windows and Unix/linux/ If it's MAC or can be. then replace all
\r with \n first.
e.g., $str= preg_replace("%(\r\n|\r|\n)%", "\n", $str);

I have a question I can't answer by myself. :)
Do I need to use "--with-pic" option when configuring php 4?
I'm going to build it as an Apache 1.3 DSO module and going to
run multiple instances of Apache (under different users). I
use Linux (kernel 2.4.30).
Generally, when one may need to use "--with-pic"?

You should be able to set up a LAMP box directly from the distro's install
CD. Grab the distro of your choice, run the install, and during the phase
of the install where you choose the packages you want, choose Apache, MySQL,
and PHP. That will get you going with LAMP.
On the other hand, there are real benefits to doing it yourself. Install a
base Linux system, then go get the latest-greatest from the Apache, MySQL,
and PHP websites, and install them seperately. You will not only get the
latest versions that way, but you will gain a better understanding of how
they fit together.

Hello,
I am not quite sure if this is the correct mailing list to post this
question, but here I go anyway. I have a vanilla Fedora Core 3
installation, and I am trying to run a php script through a local
website that has calls into a MySQL database. I can run this script
at the command line using the php PHPScript.php command, and it runs
perfectly. When I run it through the firefox web browser, I get an
error that says:
[client 127.0.0.1] PHP Warning: mysql_pconnect(): Can't connect to local
MySQL server through socket '/var/lib/mysql/mysql.sock' (13) in
/var/www/html/index.php on line 4
I have checked the socket, it exists. Again, if I run this script just
using php, it works just fine. However, when running it through Apache or
httpd it does not. What am I doing incorrectly?
Thank you for your time,
Robert

Look into the SELinux settings for your system, if you have that
enabled, by default PHP is not allowed to get that file via the user
nobody.
If you look into /var/log/messages you'll see some selinux messages.
You either need to disable selinux, or set your policy...http://
fedora.redhat.com/docs/selinux-faq-fc3/
that url should help.

im working on a comment/forum app and when a user enters too many
carriage returns i want to remove them before insert to db.
example, user input:
-----snip-----
[quote=user]
foo
[/quote]
<bunch of extra lines>
more text...
-----snip-----
I to change to:
[quote=user]foo[/quote]
more text...
i try this regexp:
$message =
preg_replace('#(\[quote(=("|"|\'|)([^\]]*)\\3)?\])\s+#i', "\\1\n",
$_POST['message']);
doesn't remove / replace anything.
I need for it to work when they use [quote=xx] or [quote] and ends with
[/quote]
any help?

thanx for the reply, but 1 problem. there is not only \n there are \r in
the POST too (carriage returns) so a string can look like this:
$string = '[quote=xx]\r\nfoo\r\n[/quote]\r\nmore text\r\n\r\n\r\n\r\n';
and your regexp will only catch if there is just \n
any solution for \r\n in combination too?

that works for my orginal request, but i found something else:

now if they enter more carriage returns i get the results from above.
its no big deal, but you always have someone trying to 'break' the system.
thanks, i really need to learn some regexp.

Hi all, I just discovered the gethostbyaddr() function. By reading the
user contributed notes, I get the impression that either this function
may cause performance problems, or a user-contributed function based
upon it may be slow. So, is gethostbyaddr() slow? Is it dangerous?

I'm guessing that the speed is very much dependent on the speed of the
underlying dns query mechanism - so probably yes, it's relatively slow.
and not something you want to be doing many times within a single request.
probably someone will now declare me a retard ;-)

I can say from personal experience that gethostbyaddr() and
gethostbyname() can seem almost randomly slow, depending on machine, OS,
software, who knows. I'm not smart enough to figure out the reason why
it can vary so much on machines with nearly the same configuration, but
I can tell you that it works perfectly fast most of the time. Then
there's that other 5% where something makes it slow as molasses.
I have two machines that are so similar it's not funny, but
gethostbyname() takes 1/10 s on one, and 5 s on the other. I have yet
to figure out what's the difference between them that causing this.

if you are quering a external host, the bad network conditions may
cause delay in results.
if your server is connected to a heavily loaded hub/ cheap switch, or
the target hosts DNS servers are poorly configured/ slow in responce
it adds further delay to your result.
try dig/ nslookup on your server for the target hostname/address, you
may experience the same delay as with the php function.

i missed another keypoint..
if you are running unix/linux server, you need to have a properly
setup resolv.conf
or if you experience a slowness while you quering your own domains,
check whether you DNS servers are providing "authoritative" answers to
your domains.

Thanks for the reply. The problem I had - and that I was trying to
briefly describe - is not quite explained by slow DNS lookup, at least
not so far. I have one script, run on the same machine:
takes less than 1 second on CLI:
# php gethostbyname.php
Content-type: text/html
X-Powered-By: PHP/4.3.2
gethostbyname(www.imakenews.com) took 0.0010 s and resolved to
208.254.39.65<br>
gethostbyname(rssnewsapps.ziffdavis.com) took 0.0005 s and resolved to
63.87.252.162<br>
gethostbyname(itpapers.zdnet.com) took 0.1922 s and resolved to
216.239.113.159<br>
gethostbyname(rssnewsapps.ziffdavis.com) took 0.0005 s and resolved to
63.87.252.162<br>
Running CLI again, host names are apparently cached, because then they
all return in .0005 seconds.
takes 20 seconds under Apache 2.0.46:
gethostbyname(www.imakenews.com) took 5.0071 s and resolved to
208.254.39.65
gethostbyname(rssnewsapps.ziffdavis.com) took 5.0099 s and resolved to
63.87.252.162
gethostbyname(itpapers.zdnet.com) took 5.0097 s and resolved to
216.239.113.159
gethostbyname(rssnewsapps.ziffdavis.com) took 5.0099 s and resolved to
63.87.252.162
This will happen consistently, with less than 1/100 s variation in time
for each lookup.
Any DNS lookup tools are perfectly fast when run from the command line.
Also, other machines in the same subnet, using the same DNS servers,
using 99% same apache config files (I diff'ed 'em) run just as fast
under same apache/php version as they do command line. It's hard to
imagine what external DNS problem could exist that would affect only one
of our servers, and on that one, only apache/php and nothing command
line. Something else is going on, but my initial tries of
downgrading/upgrading both php and apache haven't made a different yet.
Perhaps you have another suggestion?
Thanks,
kgt

could you please mention the environment, i mean, the os, and the
versions of php? is it binary install or a compile?

attached mail follows:
I've wanted to make a ping 'program' in PHP, so after reading up on
this, it occured to me that the only difficult thing was to calculate
the ICMP checksum. So after some heavy reading I could calculate this by
pen and paper. And after some hours trying to make my calculations into
PHP code, I discovered this piece of code in the online doc:
(by Khaless [at] bigpond [dot] com)
http://dk2.php.net/manual/en/ref.sockets.php
<?PHP
// Computes Internet Checksum for $data
// will return a 16-bit internet checksum for $data
function inetChecksum($data)
{
// 32-bit accumilator, 16 bits at a time, adds odd bit on at end
for($i=0;$i<strlen($data);$i += 2)
{
if($data[$i+1]) $bits = unpack('n*',$data[$i].$data[$i+1]);
else $bits = unpack('C*',$data[$i]);
$sum += $bits[1];
}
// Fold 32-bit sum to 16 bits
while ($sum>>16) $sum = ($sum & 0xffff) + ($sum >> 16);
$checksum = pack('n1',~$sum);
return $checksum;
}
?>
Now, after discovering the unpack function it all became a lot easier,
so I've made my own checksum calculator, which works approximatly 5
times as fast (and it dosn't have the for loop limitation of data
length), and all the tests I've done it gives the same result as above:
<?php
function myChecksum($data)
{
$bit = unpack('n*', $data);
$sum = array_sum($bit);
if (strlen($data)%2) {
$temp = unpack('C*',$data[strlen($data)-1]);
$sum += $temp[1];
}
// The next 2 lines of code, is stolen from the
// original ping program written in C
// Stolen code start:
$sum = ($sum >> 16) + ($sum & 0xffff);
$sum += ($sum >> 16);
// End of stolen code
return pack('n*', ~$sum);
}
?>
Can anyone tell me, if there will be any example, where the 2 functions
wont give the same output? The piece of code I think could be the most
trouble is the piece I've stolen, in the other function there's a while
loop, so if I a very long data input, it wouldn't be the same output,
but I've tried with large strings and they still give the same.
So to sum up, will the 2 functions always calculate the same.

attached mail follows:
I creating a out.php file that will record clicks, and the redirect
the user to the site that he wanted. I am currently using
header("Location: $url"); which works as expected. The only problem
is, that the browser does not send $HTTP_REFERER info to the recieving
site.
However, that particular site is also linking to me via a out.php
file, and the browser DOES set $HTTP_REFERER on my site. So I've been
googleing for two days, and came up with this: There is a site that
displays the server reesponse of any server. So I put both of our
out.php files to the test. First, his server response:
HTTP/1.1 302 Found
Connection: close
Date: Thu, 04 Aug 2005 15:19:01 GMT
Location: http://lyricslist.com
Server: Apache/2.0.50 (FreeBSD) PHP/5.0.0

Client-Date: Thu, 04 Aug 2005 15:32:32 GMT
Client-Response-Num: 1
X-Powered-By: PHP/5.0.0
This redirects to lyricslist.com and correctly sets the $HTTP_REFERER
variable. Now, my server response:
HTTP/1.1 302 Found
Connection: close
Date: Thu, 04 Aug 2005 15:39:25 GMT
Location: http://lyricslist.com
Server: Apache/1.3.33 (Unix) mod_auth_passthrough/1.8

Client-Date: Thu, 04 Aug 2005 15:39:29 GMT

X-Powered-By: PHP/4.3.11
This just does not set the $HTTP_REFERER variable! The referer
variable is even set to the original page that linked to out.php, and
not out.php itself! I have tried in IE 6.x, Firefox 1.0.6, Pheonix 0.7
(remember that!), and Opera 8.0. What could be the difference?
Thanks to all who rack thier brains on this one! It's been a fruitless
two days for me...

Many version of zip won't append the .zip extension. In such a case,
what you have above will try to name the zip file the same as the
existing directory, which obviously won't work. Try:
shell_exec("zip -r ddd.zip ddd");

There's a few ways. highlight_file() and highlight_string() will do it.
Another way is to symlink to the .php file as extension .phps -- and
provide a link to the .phps file.
