[PHP] IMAP and NNTP
The manual says that the majority of IMAP commands can be used for NNTP
access.
This code works fine.
$status =
imap_status($nntp,{news.gradwell.net:119/nntp}#news.gradwell.
lists.test,SA_ALL);
if($status)
{
print(Messages: . $status-messages ).br\n;
print(Recent: . $status-recent ).br\n;
print(Unseen: . $status-unseen ).br\n;
print(UIDnext:. $status-uidnext).br\n;
print(UIDvalidity:. $status-uidvalidity).br\n;
This produces the following output.
Messages: 7
Recent: 7
Unseen: 7
UIDnext: 111
UIDvalidity:-1091568946
The 111 is reasonable as there are 6 messages on the server, numbered
104-109 on the server.
The code $msgno = imap_msgno($nntp, '106');
echo msgno is: $msgno br\n;
outputs msgno is: 2
the inverse
$uidno = imap_uid($nntp, $msgno);
echo uidno is: $uidno br\n;
outputs
Warning: Bad message number in /nfs1/corixa/webs/cgi-user/news/news.php
on line 60
uidno is:
So it appears that 106 looks up as 2, but 2 doesn't produce 106, but an
error instead.
Has anybody honestly used the IMAP functions to drive and NNTP server
or am I wasting my time.

[PHP] MySQL and PHP arrays
Is there a generally recommended way of storing an array created by PHP
in a MySQL database field ?
What type of field should it be, and how do you get the whole array
back in one go without reconstructing it row by row, if that is
possible?

serialize() and unserialize().

Any text field will do, just make sure it's large enough for your data.
Thanks that now makes much more sense. So when I look at the data in
the database I see
a:142:{i:1;s:52:[52characters];i:2;s:37:[37characters] and so on for
the 142 elements of the array.
But getting it out is not so easy.
$result = mysql_query( select post from posts where id = '$id' )
Gives $result as a Resource id #6 which is OK but I cant find the PHP
MySQL command to get the whole field back to unserialize it :(

[PHP] preg_match fails to fill $matches
I have
At the top of a loop
$ts = '/(' . $trigger_string .')/is';
echo trigger_string is $ts br;
$matches = array();
$hit = array();
In the loop
$hit[] = preg_match ($ts, $line_in,$matches);
Now the $hit array fills up correctly, if the trigger string is on the
line just read in, putting 1 or 0 in $hits. But the string that
triggered the match is not put in $matches. The manual says it should
be.
Anyone any idea what I am doing wrong ?

What's your actual code? How are you looking for the match in $matches? If something
was matched, then it'll be there.
The full cod in the loop is.
$cnt = 0;
while(!feof($fp))
{
// Get body
$line_in = fgets($fp,4096);
$cnt++;
// looking for the other end of the marker found above
if (substr($line_in,2,strlen($line_in)-5) != $marker )
{
$body= $body . $line_in;
$hit[] = preg_match ($ts, $line_in,$matches);
$line[] = $line_in;
$char= substr($line_in,0,1);
$quote[] = preg_match ($qs, $char);
}
if (strpos($line_in, $marker) 0 ) {
break;
}
}
Later on in the code after the loop I do
echo printing array matches br;
print_r ($matches);echo br;
echo printing array hit br;
print_r ($hit);
echo printing array quote br;
print_r ($quote);
echo printing array lins br;
print_r ($line);
$lcnt = count($line);
echo cnt of line array is $lcnt br;
$hcnt = count($hit);
echo cnt of hit array is $hcnt br;
$qcnt = count($quote);
echo cnt of quote array is $qcnt br;
$mcnt = count($matches);
echo cnt of matches array is $mcnt br;
the arrays $hit and $line and $quote all print data, and all the
count($array) print a value except the $matches array and count are
empty.

$matches is going to be over-written after every time through the loop! It
doesn't add it all up.
Add in a
$var[] = $matches;
or something inside of your loop to keep track of them all, then
print_r($var) to see what it contains.
Thanks that fixed it I ended up with. with the $ts string | and | the |
$hit[] = preg_match ($ts, $line_in,$var);
$matches[] = $var;
but it still it needed $var = array(); before it would work. The
results are interesting and shows I don't understand arrays :(
print_r ($matches);
printing array matches (reformatted)
Array (
[0] = Array ( )
[1] = Array ( )
[2] = Array ( )
[3] = Array ( )
[4] = Array ( )
[5] = Array ( )
[6] = Array ( [0] = and [1] = and )
[7] = Array ( [0] = the [1] = the )
[8] = Array ( [0] = and [1] = and )
[9] = Array ( )
[10] = Array ( )
[11] = Array ( )
[12] = Array ( [0] = and [1] = and )
[13] = Array ( )
[14] = Array ( )
[15] = Array ( )
[16] = Array ( [0] = the [1] = the )
[17] = Array ( )
[18] = Array ( [0] = and [1] = and )
[19] = Array ( )
[20] = Array ( )
So how do you interpret that a sort of instant 2D array.

Thank you very much that is brilliant, I would never have thought of
that.
Do you think that:
if (preg_match($re, $posting, $hits)) would slow it down at all. The
$buzzwords will be kept in a file to be loaded before each run, every 5
minutes. I could therefore keep a count of which words hit most
frequently and move them to the top of the list.

If I look at $body with Hex editor there are lots of 0D 0A pairs and
further if I look at the source of the page generated by
echo $body; I can see the CRLF's
This is giving me pains in the neck :(

No idea whether this would be faster (it's certainly easier to code):
explode() text into an array
place your banned words into an array
array_intersect() to find words common in both
Thanks for another method,
Do your own benchmarking!
That is the easy bit.

[PHP] String searching peformance
I am looking for the most efficient way to search for Trigger words
in a big string.
I have a string, $body which is all of the body of any particular
Usenet Post, so it can be as short as Me too and up to some, as yet
undecided, limit say around 10Kbytes.
I have a list of words in an array, maybe 50 words of up to 8
characters.
I need to search the $body for the presence of $word and if any $word
in the array is found in $body Trigger an action.
This is a moderation bot for a beginners group, NO Flaming No swearing
No Abuse, you can imagine a list of words, idiot, fool, shit, FOAD, and
so on. When *any* one is found the post is diverted for manual
intervention, and searching stops.
Just guessing I would imagine
while ( $flag == true )
if (strpos($body, $word[]) 0) {$flag=false}
What I really need to know is which is the fastest loop?
Which is the fastest match, strpos?
Which is the fastest comparison?
What other optimisations are possible to maximise search speed?

[PHP] PGP signing text from called from PHP
Using PHP 4.1.2 I need to PGP sign a piece of text and detached the signature. I have
read a lot in the archives and and about the better exec() calls in 4.3.
However I cannot find a reference that indicates the best way to pass a set of
arguments out of a PHP script to PGP.
I need to use pgp2.6.3i the pgp command line looks like a bit this
pgp -sabf -u pgpuser pgppassphrase text pgpsignature
This has to be given to the Bash Shell with whatever works exec() system() or
passthrough(), any output can be retrieved later .
It is possible, if anyone knows how, to set ENV variable in the shell to preload the
passphrase and the pgpuser into ENV variables.
Has anyone cracked this? Any pointers to archived messages I have missed.
Any suggestions at all would be most welcome.
