[PHP] reading a word document
Hello, Would anyone know or could point me to a link which might have a way for php to read a word document? The code will run on linux, so unfortunately cannot use COM. I've done research on a third application tool which converts docs to html, but have yet to find one which keeps proper formatting and doesn't need root to install it. Would appreicate any help. Thanks!! Tom

[PHP] Switch To VoIPTelco And Save!
Hi, I want to introduce you to a new phone service that I'm using. It's called VoIPTelCo and it transforms your high speed Internet connection into a regular phone line. It works just like your current telephone service except it's 40% - 60% cheaper. You get features like Call Waiting, Caller ID Display, Voicemail, 3-Way calling, Call Forwarding and many more for a fraction of what you're paying now. You can even keep your existing number if you decide to switch to their service. With VoIPTelCo, I also save money on long distance calling. Unlike a regular phone line, VoIPTelCo is portable, which means I can get phone service anywhere in the world. All I need is high speed Internet access. For example, I use my VoIPTelCo service when I travel and there are no long distance fees because these calls are considered local. I save so much money just on this alone. Right now, VoIPTelCo is offering a ONE MONTH FREE trial period to friends and families of their customers. There is no obligation and it is completely free. If you'd like to try them out, just click on the link below and you will receive a 30 days trial period, free of charge: http://www.voiptelco.net Hope you'll find this useful.

Re: [PHP] magic quotes

about it not working on runtime data. Like gpc if this is correct do you
have another solution? I put this line in the .htaccess file it didn't work
either: php_flag magic_quotes_gpc off... Is there anyway possible? I don't
need it now but it'd be nice to know for the future dev.

Code readability is quite important when working with a team on a
project, and if you got for method 1 on things like this:
$str = 'a href='.$url.'';
It gets quite inreadable, having a double qoute next to a single quote.
while this looks much better:
$str = a href='$url';
I just did some benchmarks myself, and you can see that concatenation
is definitly a little bit fast, but it's only 2 seconds on 10 million
loops:
For 10,000,000 loops:
Concatenation single quote:5.62786102295

Hi!
Thank you for your response!
The only intention of my code was to investigate the (back then) unexpected
behavior of the if statement.
With $var['test'] set to blah this expression should be false
($var['test'] == 0) for what I know ...
$var['test'] = blah;
var_dump($var['test'] == 0);
//returns bool(true)
Now I know why this happens! According to Table 6.5 of the Operators page in
the PHP Manual in this comparison all of the values are converted to
integer. And atoi(blah) for sure will fail!;-) So you have to use === to
keep the types of the values!
I found something interesting:
[EMAIL PROTECTED]:~ php -r '$var = 'bla'; var_dump('0' == $var);'
bool(true)
[EMAIL PROTECTED]:~ php -r '$var = 'bla'; var_dump(0 == $var);'
bool(false)
version is 5.2.1
is this expected behaviour to be a difference between the two types of
quotes in this case?
greets
Zoltán Németh
I think you're little bit confused by the quotes :P
and since you don't have error reporting including E_NOTICE, you don't
see that there's some problem with your code :P
If I execute your code with the -n option, I get same results.
When I put them in a PHP file like this:
?php
$var = 'bla'; var_dump('0' == $var);
$var = 'bla'; var_dump(0 == $var);
?
I get :
bool(false)
bool(false)
and you probably also ;)

In my case Var_dump() returns string(4) blah as expected.
Using

Are you wanting to only test for a empty/non-empty string?
if so, use this.
if ( empty($var['test']) ) {
echo var['test'] is empty;

TypeCasting would only be effective if you used the type sensitive

Hope that solves it for you! I'm still investigating why my first examples

After the user logs in, the user is returned back to the buy page. Now, in this exchange what's the easiest way to maintain the $_POST data?

Re: [PHP] Concatenation vs. Interpolation
You're right. There is a low benefit in performance. But I think it's
valuable
in high-traffic websites. Of course, we should consider a lot of thing to
have a better performance, but Concatenation, IMO, is the best practice.
Let me explain:
َActually, the programmers' preference on readability and write-ability
varies.
I think that concatenation provides a more readable syntax, since it
allows us to distinguish variables from plain strings very easily.
Consider the following code:
$str = 'My name is ' . $name . ' and I live in ' . $city;
VS.
$str = My name is $name and I live in $city;
(You may view the above code in an Editor with syntax-highlighting
capability for a better result). However, it is possible to offer
opposite examples.
In addition to the Performance on Speed, Concatenation uses less memory
than Interpolation, as explained in PHP Manual. Take a look at the
following URL:
http://us2.php.net/manual/en/language.types.string.php
Quote:
Note: Parsing variables within strings uses more memory than string
concatenation. When writing a PHP script in which memory usage is a concern,
consider using the concatenation operator (.) rather than variable parsing
Thus, I think that it is better to use Concatenation instead of
Interpolation.
Since it provides Performance, both on Speed and Memory Usage.
There is a benchmark available here:
http://us2.php.net/manual/en/function.print.php#66392

I know this isn't exactly a php related question but due to the
quality of answers ive seen lately ill give this a shot. (yes yes im
smoothing up the crowd before the question)
I have a weblog system that i am creating, the trouble is that if a
user links to an external image larger than 500pixels in width, it
messes with the whole layout.
I had found some regex code im using atm but its not good at matching
the entire image tag. It seems to ignore properties after the src
declaration and not match tags that have properties before the src
declaration .
preg_match_all(/\ *[img][^\]*[src] *= *[\\']{0,1}([^\\'\ ]*)/i,
$data, $matches);
print_r($matches);
This currently makes two arrays for me, the source location from all
img tags and a large part of the tag itself. But not the entire tag.
What i do is i match the img tag, find the src, get the image
properties, and if the width is more than 500, i shrink it down and
add width=X and height=Y properties to the image tag.
How can i match an image tag correctly so it does not cause any issues
with how the user adds the image.
You could set a class attribute for the image in
html and scale it in css. An img {width: 100%;}
would hold the size to the maximum of the parent.

preg_match_all('/img[^]*/Ui');
Off the top of my head. This wouldn't allow for using the right angle
bracket in the img tag, but that's almost never going to happen in reailty.

Tom Cruickshank wrote: Hello, What I would like to preserve in the sense of formatting is bold, italics, spacing, pictures (if any). That kind of thing. I'm aware that Word isn't the best type of document to read from, unfortunately some folks will be using that file format to upload files. Ideally, yes I do want to convert the doc file to an html file. I've tried wvWare and I really like it. Unfortunately, the hosting provider refuses to install it since you do need root access for the installation. catdoc, doesn't appear to preserve text format, so that would defeat the purpose of uploading word documents. word2x has also potential, however, I don't have root access on this system. Appreicate the feedback. With these restrictions in mind, is there any other solutions that you can think of? Not really. If you're doing this for a client, i'd tell them to find a new host or drop the idea of converting user-supplied MSWord files. Do the files really need to be converted? Aside from the fact that it's lame, you could just serve up DOC files to the browser. No, i hate that idea. Forget it. How big are these files, anyway? Could you, instead, have the users supply the information through a WYSIWYG widget (widgEdit, FCKEditor, etc.) that would do the mark-up itself? Do you have shell access to the server? If so, can you see if any of these tools are already available. Do the conversions need to be immediate? If not, you could write a handler to send them to you as they come in so you could convert them on your own machine. Not at all ideal, but ...

If your script doesn't have a predictable start page that will only be called only once per session, place the session_set_save_handler statement in an include file, and call it via require_once(). I doubt that this is correct. The save handler that is being set is not, in itself, a part of the session, but a function that is to be used to act upon the session. That is, there isn't anything inherent to the session in the function. Thus, it wouldn't be saved as *a part of* the session. It's just a handler.

Yes you can detect the meta redirect or manual refresh using your method. But only the first can be detected because when the page is served up to the browser again either the special meta redirect URL is active, non special normal URL is active, or a super special I'm redirecting but don't count me URL is active. Now what happens when the user does a manual refresh again? It's not about output, it's about detecting subsequent refreshes and determining again the source of the refresh. You must have some kind of session tracking system in place, be it a regular session or a database query that can check if an ID was already detected that indicates to discount the page load from any statistics.
