One problem could be the .doc extension. A lot of email clients will
give you a warning at best, and at worst will completely remove the
attachment of things like Word documents, due to thier ability to
contain dangerous macros. I don't think that is the problem you're
currently having, but it's good to be aware of.
Other than that, I would look at what add_attachment is actually doing
to see if it is indeed grabbing the correct file.

Hi all,
I'm using ob_start() in order to save the content of a web page into a
variable string and then save it into a file in the file system. Every thing
is done OK. The only workaround I'm doing is adding a .doc file extension
when saving the file, in order to open the file in Word.
So you are adding a .doc extension so word can render the html file as
a wor doccument?
Once the file has been created and saved as I doc file (not a doc format!),
I e-mail it!
When the client gets the e-mail, he/she should open the file either by
saving the file to the local system or openning the file directly from the
e-mail attachment. Either way, I got a blank page in Word. If I open the
document directly from the web server, without having it sent by e-mail, it
opens correctly in Word. The only problem is when the file is been
emailed!!!
what you want to do is send the file you saved to a file as an
attatchment, if you are already doing so the problem is with how you
are composing the email that is sent to the client.
You are dealing with many issues, where the problem exists depends on
a lot of issues.

Hello,
I'm writing a script to generate a javascript. The javascript would
generate a banner when it is sourced. This javascript is sourced
by another html like this:
<script type="text/javascript" language='JavaScript'
src='http://foo.com/testing/js.php'></script>
However, Sometimes the javascript doesn't show anything at all. it
seems that the php generated javascript cannot be loaded sometimes.
Maybe the generation takes too long. I'm not sure about that.
Is there anyway to deal with it?

Koala,
There is no difference with the php generated javascript and javascript on a
static html page.
Take a look at the source code of the page that has been generated in the
browser, and if that one looks as it should, it is probably your javascript
that is not doing what it should :)
And if that is the case you can join the [EMAIL PROTECTED] list for that
purpose.

Petar,
Thanks for your reply.
I've used some server side cache for that javascript generation now.
It works a lot better. Seems to me that it takes too long to generate
the javascript. Sometimes browsers decided to ignores the javascript
and just run.
I used "document.write" in that javascript. When it isn't loaded
completely, nothing shows. I wonder if there is any better way.

put this at the top of your script "ob_start();" or before any output.

You might want to be more elaborate than that... What is considered
longer, What do you mean it ignores the javascript?

This i dont understand, perhaps an example of what you are doing?

Unlike my recent posts, this could be a candidate for using ob_*
There is no need to compress it first, just use ob_start('ob_gzhandler');
if the client supports a compression method, no special things are
needed and the content sent is compressed otherwise it is sent without
compression.
see http://php.net/ob-gzhandler for more info.

Probably because the browser sees the ? in the URL, thinks dynamic and
doesn't cache the result. You can set caching headers to get around this
You also have to remember that php by default sends the headers to
prevent caching, take a look at the headers responded via a static
.jpg file and a php page tha sends an image; You'll notice all those
extra no-cache type headers that enforce any browser to not reload a
(local) cached version of the file.
To get best performance
support a HEAD request:
send last-modified: and content-length: with the orignal sending
of the file and within your php script if the client requests a
IF_MODIFIED_SINCE header check the header against the value, if it
matches respond with something like:
header('HTTP/1.0 304 Not modified');
exit;
support partial requests:
check for the http header for partial content requests (I forget
the name, perhaps someone can remind me of it) and respond according
to the http specs.
HTH,
Curt.
(Google for it), or if you want *all* browsers to do it right, even the
poorly implemented ones, you could modify the URL so it doesn't have the
?. I do this using the Apache MultiViews option and a URL similar to
/image/123.gif. That actually runs /image.php which pulls the
REQUEST_URI server variable apart to get the required image. Do both and
you should be good for all browsers.

I have an saved images I output with this...
<img src="includes/viewphoto.php?id=<?=$photo?>">
I want to use getimagesize() to get the height and width of the image and if
it is above a certain size then scale/ reduce it.
The problems are
(i) using getimage() without a url just my viewphoto.php script
I'm not sure what you mean here.
(ii) comparing and reducing the file
reducing a file tends to follow the logic of some sort:
$size = GetImageSize ($image);
$ratio = $size[0]/$size[1];
if ($ratio > 1) {
$width = $max_size;
$height = ($max_size/$size[0]) * $size[1];
} else {
$width = ($max_size/$size[1]) * $size[0];
$height = $max_size;
}
where $max_size is the largest you want your image to be in width,
then just copy it it into a new image create at that size
There are a lot of samples of this on google as jochem suggested.

It depends.
If it is a .txt file (nope)
a .doc file (mabey, pending the .doc format)
a .xml file (most likely, unless it is a poorly formatted xml file)
It all depends how the document is stored and if it keeps the charset

I want something more like the output of the unix command "file -i"
(without running a system call). And yes, they are text files.

I would go as far as configuring your default php.ini to send utf-8 as

Subject: [PHP] Problems with UTF
Hi,
I have a php based script that is called from a html page via ajax.
Everything runs fine except when I use characters such as á that ends up
like A!
After searching and testing I found that if I remove the
encodeURIComponentfrom the javascript and replace with
escape everything works fine.
So the question is what can I do from PHP side to make it play nice with
those UTF encoded chars generated from encodeURIComponent? Since escape is
deprecated I'd like to find out before I have tons of files to change....
tks.

i think a combo of what the function does and a few regex's will work.
The issue is more on how idoes it pass all the rfc's on each part of
the address, for a quick reference of rfc's:
http://en.wikipedia.org/wiki/E-mail_address
An address consists of:
[EMAIL PROTECTED]
so the question is does it pass local tests, which should be rather
simple, the domain part gets rather complcated since you cant predict
at what domain level we are talking about:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
There is a pcre expression out there somewhere in perl land that is
considered to validate all the rfc requirements of the address and is
about 50 lines worth of regular expressions with a lot of backward
matching and forward matching conditions.
So the only simple logic you can really apply is split on the @; is
local ok? are each part of the domains valid according to the rfc's.
typically it is safe to say if they put at least two periods in a name
and the characters between those periods are valid chars then it is a
valid input ( of course it doesn't mean it is a valid email)
I suppose the least you want to do is limit addresses people can use so:
local <~~ assumed invalid (no @), unless you only want local addresses
[EMAIL PROTECTED] <~~ assumed invalid since there is no tld (unless you
want a local address)
everything else is valid (as long as it passes all the tests)
So with that you want an expression that allows for:
(valid_local){1}@(valid_domain.)+(valid_tld){1}
where:
valid_local = a valid local addres
valid_domain = a valid domain name
valid_tld = a valid tld
. = period (dot)
{1} = must match once
+ = must have 1, can have more
Making a pcre expression can get complicated, breaking it apart and
validating each section will probably make it easier to deal with.

PHP list.
This is another regular expression type of question.
The very handy PHP function trim() takes excess white space off the
beginning and end of a string.
I'd like to be able to do the same thing, except instead of white
spaces, trim excess slashes: /
So for example, all of these:
/this/that/
/this/that
this/that/
////////this/that////////////
... become:
this/that
There is also the chance of more than one slash occurring inside the
desired text:
/this/that/this/that/
So that would also need to be accounted for. The above example should
become:
this/that/this/that
I think I need to use preg_replace() for this, but, as ever, regular
expressions completely throw me.
If I'm not mistaken, "#^/*#" should get me the first slash of the
string, and more if there are more. And "#*/$#" should get me the last
slash of the string, and more if there are more.
Can I test for the first and last slash in the same expression?
I think I either need something between the two that says "ignore what's
in the middle", or and and/or statement to say "replace if this occurs
at the end, or at the beginning, or both".
I've looked around and can't seem to find a way of connecting these in
the same search. However, I'm sure that is because I'm not familiar
enough with regular expressions to know what I'm looking at.
How would I connect "#^/*#" and "#*/$#" into one regular expression?
Thank you for your time and advice.

Why do people insist on over-complicating things with regexes? They're
not the best tool for every job!
Read the manual page for the trim function (http://php.net/trim) and try
using the second parameter.
