How can I force the download of .pdf, .doc and image files? I have some
links to downloadable docs in my website, but when we click the links, IE
opens the file directly in the window. I wish when the user click a download
start, even if it is a .jpg, .gif, .pdf or .doc file.
There is a way to make that in PHP?
I have the idea do ZIP the files automaticly when my PHP script upload it to
the server, but can�t figure out how to make that.
Thanks,
Rics

I think i'll use MySQL, but if you think it's easier to use XML or
something else, that'll be fine with me (as long as it's generally
available).
Thank you in advance guys :)
if you really want to, you can use CVS to do that... =)
It can be made to use a web-interface and to correctly add/do whatever
everything...

You've just described a wiki - one example of a wiki that is written in
PHP and MySQL is http://tavi.sourceforge.net. The code is a little
spaghetti-like, but you should be able to look through the database schema
to understand how they implement the multi-user text editing, and how to
handle the related problems of locking and revision control.

Wow, confusing code - but i think i got the idea. Just one thing: After
reading the code, it seems to me that every time someone makes a change
to a record, a new row is inserted into the DB with the full text of the
edited record - not just the changes. I saw that there was an automatic
expiration function, but still, wouldn't it be a drag for the server?

Yeah, that's what happens.
I think it's only a problem if you're storing truly stupendous amounts of
text, and then it's just a storage problem - drives are cheap.
If anything, storing the changes only would probably be a bigger processor
load, since viewing any one page would mean having to reconstruct the
content from all previous versions. This way, the overhead of a diff is
only incurred when you want to view changes to a file between two given
versions.
I think the rationale behind CVS storing just diffs is that it has
branches and merges, while wiki text generally does not. Also (conjecture)
it may be a historical legacy of RCS, from a time when storage was not
quite so cheap.

Another wiki is the mediawiki projec the one that powers
http://www.wikipedia.org/ this is probabl more complex than the one that
you have already been referred to. BTW according to theory the time to
retrieve a single record from a properly index database does not
increase with the number of records in the table. Inserts on the other
hand do get slowed down often significantly.

There is a fairly new project called pdml (
http://pdml.sourceforge.net/index.php ) that extends fpdf that converts html
(sort of) into pdf. I have used it some. It's new and a little buggy, but it
is usable. You could easily use Smarty, XiTemplate, or some other template
engine to manage the markup templates to use with pdml.
There are also several scripts and classes on the fpdf.org site that cover
all sorts of common tasks ( http://fpdf.org/en/script/index.php ).
IMHO DocBook may be a little over-kill and possibly overly burdensome for
this task since it requires your markup be written in DocBook XML format. I
suppose it could be worth while if you plan to create your documents in
several different formats on the fly.

http://php.net is a great site for learning PHP, I mean if that's what
you want to code it in and stuff. I haven't ever seen any private

Hi everyone !!
I want to capture the output of a certain remote command ( issued
thru a SSH session to a remote server) in PHP.
The following code is working well when ran from the console
Ex: php -q test.php
<?
passthru("/usr/bin/ssh -v -i /var/wwwhtml/sshtest/id_rsa
[EMAIL PROTECTED] uptime");
?>
But when called from apache .. It's not giving any ouput.
[EMAIL PROTECTED] is well configured for ssh without passphrase
I've checked the file permissions of /var/wwwhtml/sshtest/id_rsa
It's given read permissions for the user 'apache' ( apache is running
as apache:apache )
Any hints ???

But have you tested this as user apache from the command line?
su - apache
/usr/bin/ssh -v -i /var/wwwhtml/sshtest/id_rsa [EMAIL PROTECTED] uptime
Chances are you will also need to add -o "BatchMode yes" to that ssh
command.

I don't know much about sockets, so I couldn't say. If the console
will connect via ssh, isn't that a stateful TCP connection? Can you
keep that connection open with a "keep-alive" or "heartbeat"? Can the
ssh server notify the application when the ssh session dies? How
expensive is it for the application to discover a dead listener?

Unless you're confident that performance problems will occur, I would
encourage you to completely ignore performance, develop the simplest
implementation and test, measuring actual performance.

Just google "event listener pattern" or "observer pattern".

Hi
How can I parse HTML page which I fetched by PHP so some part of text would
be replaced by other text.
Also, I managed to delete all HTML code from page (with this code
$data[0] = preg_replace("/([<])+([^>])+([.])*([>])+/i","", $data[0]);
but also would like to delete all chars except numbers from page, can this
be done?
Regards.
Zoran
Your first question:
To replace certain elements take a look at preg_replace()
http://us4.php.net/manual/en/function.preg-replace.php
Example:
$foo = 'stuff <b>silly stuff</b> more stuff';
echo preg_replace('/\<b\>(.*)\<\/b\>/', "<h1>$1 lookie now</h1>", $foo);
Your second question:
You could just use strip_tags()
http://us4.php.net/manual/en/function.strip-tags.php
Your last question:
To delete everything but numbers you could $content =
preg_replace('/[^\d]/','', $content);
Hope that helps
Jim Grill
Hi
This works great. One more question about preg_replace. Is it possible that for every
match other text is replaced?
By this I mean when some text between <b></b> has been found that text is replaced
with some Text, on second match, text between <b></b> is replaced by some other
different text etc.
Btw, where I can find patterns that are valid?
(something like (\w+), (\d+)+i etc.
Thanks.
Regards.

The fraudulent orders that I receive on my site come with email
addresses of eight random alphanumerics @yahoo.com.
Is anyone handy enough with regex or can show me a quick way to test
for that, so I can at least refuse all orders with that pattern? (it
will work for a little while, until they get wise and change patterns
again.)
Many thanks,
- Brian
PS - If anyone wants an update: the orders stopped for a while but
started up this weekend with a vengeance. Now they are coming with
valid address verification AND card validation numbers! Pretty darn
good, whoever's doing it. One of the cops I've spoken with says that
they're making a large number of small charges (like mine) to these
cards and then, in one case, placing a large $2000 order from QVC. In
that case the large charge was declined, thankfully.

Can anyone tell me how to convert a date stored in the format
"YYYY-MM-DD" to an integer of seconds since unix epoc,
then add $daysToAdd days to this value (I suppose if the integer was
a number of seconds it would have to be $daysToAdd*60*60*24 to get
the number of seconds to add)
then convert the new value to a timestamp which I can output using the function
string date ( string format [, int timestamp])
I tried doing this with mktime() and couple different ways using
strtotime() and also with strftime() but I kept getting -1 as the
result for strtotime() indicating the function couldn't interpret the
given date.
I've been through all the date-related functions in the manual I can
think of, but I'm stumpped on this one...

Hi,
Try
$date="YYYY-MM_DD";
$da=explode("-",$date);
Now
$Y=$da['0'];
$M=$da['1'];
$D=$da['2'];
then use mktime();
Hope you will get the results.

Is this a MySQL timestamp? If so, you can use TO_UNIXTIME() in your
query to return a Unix timestamp instead of a MySQL one. You can use
DATE_ADD() to add days to the timestamp. You can also use DATE_FORMAT()
to format the timestamp before it's returned also.
If you don't want to do that, what's wrong with strtotime('YYYY-MM-DD')
to get the unix timestamp?

Jason,
This seems to work fine for me:
<?
$daysToAdd = 5;
$secondsToAdd = $daysToAdd * 86400;
$dateIn = "2004-07-24";
$dateInStamp = strtotime($dateIn);
echo date('m/d/Y h:i:s',$dateInStamp+$secondsToAdd);
?>
... as does the more condensed version:
<? echo date('m/d/Y h:i:s',strtotime("2004-07-24")+(5*86400)); ?>
If strtotime() is returning -1, that means that it's having trouble
converting your YYYY-MM-DD date to a timestamp. The common pitfall is
that you've got the month and day mixed up (YYYY-DD-MM), or that you're
not using 2 digit numbers on the day and month (and 4 digit on the
year).
If you're having trouble with strtotime(), ech out the date you're
trying to convert, to make sure it's what you're expecting.
It's also worth pointing out that we've made no considerations for
timezones, daylight savings, etc.
UNIX timestamps are all GMT, so if the times you're seeing are not as
expected (and the dates you're collecting aren't GMT dates, then you'll
need to dig a lot deeper -- it's depends how much accuracy you want.

string date ( string format [, int timestamp])
I tried doing this with mktime() and couple different ways using
strtotime() and also with strftime() but I kept getting -1 as the
result for strtotime() indicating the function couldn't interpret the
given date.
I've been through all the date-related functions in the manual I can
think of, but I'm stumpped on this one...

How is the date stored, MySQL db??? if so, you can select dates out as
unix timestamps. Otherwise i would use mktime or strtotime...

beware of dates before 1969.

Hi all,
Please tell me how can I fetch an html document from a web page, let's say
starting from the character 1000, and get the text until the caracter 5000.
In fact, I want to use the GET or POST method, and to also send to the
server the HTTP header:
Range: bytes=1000-5000
Thanks.
Teddy

I've been reading for the last three days about character encodings and
such, but, have still been unable to figure out what I think should be a
simple solution.
All I want to do is take curly or "smart" quotes that have been pasted or
entered into a form field and convert those into straight quotes (") before
I store the text in my database.
It appears the data passed from the form to my PHP script is encoded as
Unicode. My version of MySQL does not support Unicode character encoding,
so, I need to convert that into Latin1 (or ISO-8859-1).
When I use iconv() to translate the data that contains curly quotes, the
string gets chopped off at the very first curly quote and the rest of the
string is lost. This is the command I am using:
$var = iconv("UTF-8", "ISO-8859-1", $var);
When I use utf8_decode(), I at least get the whole string back, but, all the
curly quotes and apostrophes are turned into ? question marks.
So, I presume there must be some way to convert those curly quotes into
straight ASCII quotes while the text is still in Unicode format, before I
run this through either iconv() or utf8_decode(). But, I've searched all
over for two days and can't figure out how to accomplish this.
I'd really appreciate someone's help with this! It's driving me nuts!!
Thanks,
Monty

Hi all,
yeah, i know, i did do quite a bit of searching but I just cant find it...
Does anyone have the regex to make sure an http address is full and without
error? like http://www.example.com
http://www.php.net/parse_url should do what you require. If all you want to
do is filter out the different parts of the url and check if they exist or
not.
[ ignoring the rather OT discussion that this thread has lead to ]
