[PHP] create word files

[Roman Duriancik]

I have problem with creating word file in PHP script. I create table in 
word document but sometimes php send me error message : "*Warning*: 
(null)(): Invoke() failed: Exception occurred. *Source*: Microsoft Word 
*Description*: There is insufficient memory" and then php script 
generate only word document without table.
What can I do ?

Thanks

The solution is to have a common share that all servers in the LB scheme
use for storing session variables.

yes, there is.
I have read about: http://docs.php.net/en/install.windows.building.html
which is exactly that resource.
Can you send a new link about this issue.
why? that resource shows you what to do just fine, simply read php5 
instead of php4 everywhere that it's mentioned.

Personally though, I use the SDK, so that means I compile it using 
nmake. It's not really that hard.
I'll explain my way of compiling (bit more flexible):
1. follow the instructions (on the page you posted the link to) up till 
you get to "Compiling". What comes after this is different from what it 
says there.
2. Start up the command-line with the environment variables registered 
(if you have Vistual Studio, there'll be a link to such a thing from the 
start menu. Alternatively, you can use Start>Run, type in "cmd" (no 
quotes). navigate to whereever vcvars.bat is located, and run it. Once 
done) go (back) to the c:\work directory (or wherever you put the 
source-files in).
3. run "buildconf.bat:
4. run "cscript /nologo configure.js --help" (no quotes), and you'll get 
a list of configure options you can set. This way you can also compile 
in certain extensions, which makes loading them faster, but also makes 
your php install (a lot) bigger.
5. Once you've configured it, simply type "nmake"
6. you'll get a couple of files in the Release_TS or Debug_TS directory, 
depending on if you built a Debug build or not, php5ts.dll (or 
php5ts_debug.dll) is the most important one. You'll also need another 
library to connect to your server, but which one that is really depends 
on which server you have, and what you configured PHP to work with (eg. 
apache2 support is given via php5apache2.dll).
6. Once you have those, simply follow the instructions given in 
c:\work\whatever_path_you_put_php_in\win32\install.txt, and it should 
all work just fine

Thanks so much again and good work to all.

If the 2 databases are on the same mysql server and the MySQL user has access 
to both databases, You can easily use join:

Select name FROM db1.members, db2.addresses WHERE db1.members.id = 
db2.addresses.member_id

Putting the ^ _inside_ [] means NOT, so if any of the chars a-z0-9 is in the 
string it´s NOT matched.

Also there´s no idea in having a-zA-Z in the pattern since eregi() is case 
insensitive.

[PHP] Exchanging Data among processes

[Matheus Degiovani]

Hello,
How can I exchange data among processes (i.e. two or more users 
accessing a php webpage)? The two "usual" ways would be using either a 
database or file, so I was wondering if there is another, more "fast" 
(with reduced latency) for different pages being processed to exchange 
information.

In other words: how (if) can I make a chat program that doesn't use 
files or databases to exchange information between users.

Thanks.

Re: [PHP] pass variable from vbscript to php

[Ashley]

Ok, apparently I wasn't clear enough with my explanation due to the 
responses I have received.

I have a webserver (not on the same computer as the users) that is 
hosting an Intranet app.  I want to obtain the username of the current 
person logged into the workstation that is connecting to the Intranet.

From what I have read this is impossible to accomplish from the server 
without prompting for a username/password.  I found an activeX control 
(called NWSess from Novell) that will provide the currently logged in user.

The problem is that I need to take this variable (provided by the 
activeX control to a vbscript) and pass it to PHP so that it can be 
used.  I don't typically use vbscript so I would really like to put the 
variable in PHP so that I can use it for other things.

I hope this explains what I am trying to accomplish a little better and 
thank you for the responses thus far.

If PHP is running on the same computer that the user is logged into, 
then you can use $_SERVER['REMOTE_USER'] to get the current logged in user.

It _is_ correct. [^] means that whatever is in the [] must not be in the 
checked var to be true! Look in "mastering regular expressions" if You´re in 
doubt. There´s an example [^1-6] meaning if a digit between 1 and 6 is not in 
the value checked, it´s true:

$var1 = "123";
$var2 = "789";

if(ereg("[^1-6]", $var1))
  print "$var1 is true";
else
  print "$var1 is false";

returns false

if(ereg("[^1-6]", $var2))
  print "$var2 is true";
else
  print "$var2 is false";

returns true

It´s untested though :-)

Re: [PHP] functions vs classes

[Brent Baisley]

At the most basic level a class allows you to group your functions 
together. On small projects, grouping of functions may not seem to buy 
you anything. But the bigger the project gets, the more you would like 
to be able to keep your functions separated into groups.

One simple advantage of classes is that they prevent naming conflicts 
with your functions. This is very important when you are sharing code 
since you don't know what another programmer named their functions. 
What if you both name a function "get_one_record"? If you use classes, 
you only need to keep the names of your classes unique. Which then 
means you can use the same generic function name across all your 
classes, and you interface within your classes in a consistent manner, 
only the context changes.

For instance, you may have a class call "companies" and another called 
"contacts". Within each you may have functions called "get_list", 
"get_one" and "delete_one". Same function names, but in different 
classes so they don't conflict. Now you could create a generic 
interface to view a list, view a record or delete a record. What data 
is displayed depends on which class you load. The function names are 
all the same, so you don't need to change your code when you change the 
context (companies or contacts).

This is hardly a tutorial on OOP. But maybe it will give you an idea of 
the benefits of using classes.

The way I see it, is a function if for repeated use in a project

is this correct?
Although one could just include the function library in multiple 
projects.

ActiveX controls are in the COM family.  If you don't know about COM
then you can start by looking here:
http://www.microsoft.com/com/default.mspx

Now... when you find the list of commands / variables that you will need
from the ActiveX container then you can make those calls with PHP.  The
relevant part of the PHP manual is:
http://php.net/manual/en/ref.com.php

P.S. this sounds pretty interesting.  I (and probably others) would
appreciate it if you would post back to the list with a [SOLVED]
response that shows PHP code you used to get this working.

Re: [PHP] pass variable from vbscript to php

[Ashley]

Just so that I don't start working in the wrong direction, do you mean 
that I can get the same information from the activeX control directly 
from PHP rather than having to do it with vbscript?

I am not much of a coder so any help porting the vbscript to PHP would 
be great.  The code that I am using to get the information from the 
activeX control is:
<--


	for each tree in NWSess1.ConnectedTrees		

		anyTree=tree.FullName

		anyUser=NWSess1.LoginName(anyTree)

		output=output+"Tree:"+anyTree+", userID:"+anyUser+vbcrlf		

	next

	//msgbox output


-->

I found this code on Novell's site so I didn't make this myself.
In the mean time, I will look at the information that you gave me and 
see if I can figure it out.

Thanks,
Ashley

Re: [PHP] What's the going rate for making websites ?

[Brent Baisley]

That would be between $10 and $150 per hour or more. One can easily 
find and hire a college kid to slap together some open source programs, 
maybe throw a bit of Flash and fancy graphics on a web page and the 
project is done for $10 per hour. Of course, there is no cohesiveness 
or consistency to the "finished" website, and there was no reason to 
use Flash code, except to say the website uses Flash. All the text is 
actually graphics so there is no easy way to update the content. But 
the site works and it was done in 20 hours. So what is some of the site 
doesn't work if you are not using Internet Explorer under Windows, it 
will work for 85% of the people.

For $150+ per hour, you would get security analysis, usability 
analysis, browser testing, performance analysis and testing, adherence 
to standards, project management, scalability and maintainability. 
Perhaps even return on investment (ROI) estimates. The time frame will 
be a lot longer than the $10 hour work, but you won't have any problems 
tracking someone down to fix bugs and it will encompass things the 
client hadn't thought of.

Just a motorcycle club? If it's just some graphics and a discussion 
area, that's not too hard. There is a bunch of open source forum 
software available. Is there going to be a mailing list? Now that's 
including membership and people's personal information. You need to 
take security into account, especially SQL insertion, cross-site 
scripting, the hosted OS, etc.

Prices charged can be all over the place based on the talent of the 
person(s) doing the work. You may choke if someone said they would come 
up with a tag line for your company for only $20,000. That's not even a 
website, but a one line sentence. But that's about what HBO paid for 
"It's not TV, it's HBO.". In hindsight, $20k was pretty cheap.

So, what you charge depends on your talent and what needs to be done. 
$20-$50 per hour is probably the most common range for someone who 
doesn't really do this professionally, but knows they can do a decent 
job. You can come up a project price based on your hourly rate.

Bottom line, there really is no answer. I used to charge $75 per hour 
when I did consulting during the dot com era and my clients were 
telling me I was charging them too little. Some even saying I should 
double my rate.

Re: [PHP] pass variable from vbscript to php

[Ashley]

Ok, I did a quick scan of the COM section on PHP's site (linked below) 
and found this requirement:
"COM functions are only available for the Windows version of PHP."

In my first post, I mentioned that I am running my webserver on a 
Netware 6.5 server.

In light of this I am guessing that this suggestion will not work.  Is 
this in fact the case or is there another way around this?

OK.

From what I have read this is impossible to accomplish from the server
without prompting for a username/password.  I found an activeX control
(called NWSess from Novell) that will provide the currently logged in user.

Apparently it's not impossible to do this without prompting for
the username / password then eh?
ActiveX controls are in the COM family.  If you don't know about COM
then you can start by looking here:
http://www.microsoft.com/com/default.mspx
Now... when you find the list of commands / variables that you will need
from the ActiveX container then you can make those calls with PHP.  The
relevant part of the PHP manual is:
http://php.net/manual/en/ref.com.php
P.S. this sounds pretty interesting.  I (and probably others) would
appreciate it if you would post back to the list with a [SOLVED]
response that shows PHP code you used to get this working.

Use the appropriately named file_exists() function.

Hello Chris,
Matheus,
 As a start I would check out using sockets:

Did some experiments, and it seems this would work great. Thanks a lot! :)
The only problem is that not all (if not almost all) hosting services 
disable sockets...

You should be able to translate all of the above code into PHP.  Send us
another message if you have trouble with some part of it.  Exact process
will depend on PHP4/PHP5 though.  Again, refer to this link:
http://php.net/manual/en/ref.com.php

Personally, I'd code this for use in a PHP5 parser.

Re: [PHP] pass variable from vbscript to php

[Satyam]

One way you can do it is to put an invisible  on the same page as 
the  which provides you the user information.  When you get, via 
vbscript or javascript, the userid, then you set the src property of the 
 to that of a page where you will process that info, appended with 
the information taken from the .




Asiming the property of the ActiveX object you want to send to the PHP 
server is called UserId, whenever you are sure you can read it (perhaps an 
event or whatever) you do:

document.getElementById('iframename').src = 'ValidateUser.php?UserId=' + 
document.getElementById('objectname').UserId


The page ValidateUser.php would receive the UserId as an argument in the URL 
(and you can add as many as you want) and may reply with whatever response 
is apropriate.  That answer will go into the body of the iframe document.

Thus, assuming that you reply with a 0 or 1, you will get that by having an 
function attached to the onLoad event of the .  The onLoad will be 
triggered when a response is finally received.

The reply you will get as

document.getElementById('iframename').document.body.innerHTML

which you could check by doing a:

[PHP] Compact, human-editable serialization

[GamblerZG]

Somewhere around here I asked about human-readable serialization and 
there was no solution that fitted my needs. So I wrote my own 
serialize/deserialize pair. The decode function is different from the 
one I posted here before. This function, in my opinion, is written very 
efficiently, but it's still about 10-50 times slower than serialize. I 
guess it's not too bad, because I compete with pure C++ code, but I 
would still appreciate any suggestion for performance tune-up.

PS: If someone would write the same functions in C, they wold probably 
be faster than PHP's de/serialize. And they provide output that is much 
more compact. And it's human-editable. PHP developers, if you read this, 
think about it.

[PHP] MySQL empty row

Until some time I could make a new empty line in mysql with this query:

where $_SESSION['type'] was the table I wanted to use but now I get an 
error and since I use DB I just get this error

INSERT INTO `authors`() VALUES ()
*Warning*: Cannot modify header information - headers already sent by 
(output started at 
/usr/local/ftp/faps/public_html/pubDB/edit/newline.php:9) in 
*/usr/local/ftp/faps/public_html/pubDB/edit/newline.php* on line *19

*This is the file

   include "../modules/connect.php";
  
   array_pop($_REQUEST);
   $query = "INSERT INTO `".$_SESSION['type']."`() VALUES ()";
  
   $res =& $db->query($query);
   //Always check that result is not an error
   if (DB::isError($res)) {
   die($res->getMessage());
   }

   include "../modules/disconnect.php";
  
   header ("Location: ./edit.php?".$_SESSION['stayurl']);

Re: [PHP] How to call a static class and method dynamically

You can call the function statically using the double colon ( :: ) 
operator :
Ahem. Double colon does now works with dynamic names. If I'm not 
mistaken, call_user_func(array('class', 'function')) is the only way.

You have not mentioned what network you are running. IF it is a Windows
network, AND you run PHP on IIS, the server variable NT_AUTH_USER is defined
for you.  However, I suspect from the fact that you are looking at COM
objects from Novell that you are running a Novell network.

However, I believe this response was a little hasty as I do not believe that
the question involves running an ActiveX Control on a server, but on a
client.  In this case, the variables that are passed into your VBScript need
to be then added to an HTML form (via hidden input tags) and the form needs
to be submitted.

Thing is though, this means transmitting user network login details via POST
and this means that it would be possible for anyone on your network to watch
this traffic and get logins for anybody that uses your system.

Maybe a better solution in this case would be to associate a user account
with a network login when the account is created and store this information
in your user database.

HTH,

Mikey

Re: [PHP] MySQL empty row

[Andy Pieters]

Hi Neo

Just some observations and hints.

I see you use the contents of a user variable ($_POST,$_GET,$_REQUEST,
$_SESSION) without check.  Possibly you checked them on another page but you 
shouldn't rely on that. You should take NOTHING for granted.  You should 
escape the input by using a function like mysql_escape_string

Google for mysql injection will give you ample information on the why of this 
precaution.

2ndly you include a line die($res->getMessage()) which would expose security 
sensitive information about your server, and database.  You do not want this!  
Instead you can redirect to a page that explains to the user that an error 
ocured.  For yourself, you can write the error to a file on the server that 
you can peruse to debug.

Just scream if you want an example of this.

How about trying this:

unset($res);
$res=@&$db->query($query);
if($res)
 if(DB::isError($res))
...rest of your code

The HTTP specification is also that a Location header should provide the 
absolute address, not the relative.  

You might also consider rewriting your logic a bit:

Instead of depending on a connect and a disconnect file, make one include file 
like this:

function connect()
{#details of your connect
 if(connection_ok)
register_shutdown_function(disconnect);
 }
function disconnect()
{#your stuff here
}

Including (or require ing) the file at the start of the page will provide you 
with all functionality and will automatically close the database connection 
when the script finishes. (Don't use this with persistent connections though)

Also when you use functions that rewrite the header, you can either use 
ob_start, ob_end and stuff to buffer the output, or make sure you send 
nothing to the browser until after the headers are sent.
One common pitfall is having characters before the 

After the ?> must be NO character, not even a CR or LF
Best way to check this is to put your cursor right next to the > and press the 
left key.  If you r cursor moves then press left followed by del.  Keep 
pressing the del key until all the charcters after the > are gone.

With kind regards

[PHP] Almost OT - urlencode and IE

[Chris]

I'm writing a web app that passes values in the URL separated by a / . 
I'm passing these values by supplying links to them.

The writing and reading of these values is fine, I'm just stuck at the 
differing ways IE handles urlencoding the data..

IE will not work unless I double urlencode it 
`urlencode(urlencode($sData))` while Firefox and Opera (and, I imagine, 
every other non-microsoft browser out there) only needs to be encoded once.

I could gripe about IE or whatnot, but I just want to know if there have 
been 'solutions' to this problem in the past?

Thanks,
Chris

[PHP] Anyone working with UPS Online Tools?

[Chris W. Parker]

Hello,

I am in the process of integrating my site with UPS' Online Tools.
Specifically Address Validation, and Rates and Service.

The problem I'm seeing is that it's quite slow. I'm doing all my tests
on the test server and thought that querying the test server would be
the reason for the slowness, but when I tried the live server (once) it
seemed to be the same.

The test page takes about 4-6 seconds to complete.

Is this a normal time for such a process?


Thanks,
Chris.

Re: [PHP] Almost OT - urlencode and IE

[Philip Hallstrom]

You could base64_encode it... you'll run into url length issues at some 
point, but I believe that's around 4kbytes or so...

I've done this before... something like:
base64_encode(serialize($my_object));
then undo it on the other end.

[PHP] Piping email into a php script

[Jeff McKeon]

Running PHP 4.3.9, apache, mysql, qmail

I know it's possible to pipe an incoming mail message to a script in
qmial by creating a .qmail file for the user like:

|script

What I'd like to do is pipe incoming mail for a specific user into a php
script that parses it out (using mailparse I imagine) and puts the
pieces into a database table.  

On PHP.net I see an example like this on the function page for
Mailparse:

[SNIP]

[SNIP]

This looks like it will work so long as I put the required database
interface code in the "foreach" section.  However I'm a little stuck on
how to actually pipe the file into the script so that it winds up in the
$buffer variable.

Can anyone give me a clue as to how I can do this?

Thanks,

Jeff

[PHP] Adding Fonts to JpGraph

[Stephen Johnson]

I am using JPGraph for a project that I am working on right now and I have
hit a small snag -

My client wants to have the user be able to select from a list of about 20
­30 standard fonts.  JPGraph only has about six built into it and the
support in the docs is not very helpful since it wants you to register it to
get font support.  I am willing to do that, BUT, their website says they are
no longer accepting support clients.

So ‹ anyone out there have any advice our a tutorial that I can look at for
some assistance ?

Find out what they want and have them sign the design targets.

Price depends on the complexity
---
I break a job done by functional areas and how much time I expect to spend 
developing each section (i.e. - message board, general page layout and 
graphics, e-commerce store, etc.). Be realistic with your time estimates. If 
you will be using a new language then be generous with your time, but as you 
gain experience reduce that time too.

and the per Hour
-
Look at your cost of living. A person in New York City can not afford to 
charge the same rate as a person in Toledo, Ohio
I charge more for onsite (to cover gas, parking, lunch and other issues) 
than I do for offsite (working from home, I'll give then a price break).
Leave extra time for revisions to the site, I'll add between 25% - 50% to my 
time for each area depending on how the contract negotions go, if the client 
is a pain in the arse with the contract, then expect issues and difficulty 
while you work the project (a.k.a. - scope/deadline creep).

Web developers can be had for a very cheap price if one wants to search for 
them.You are the local expert and this is why you were hired (or possibly 
your reputation is very good). If a client is real persistent about adding a 
new "feature" then I will say something to the effect of, OK - Mr. 
InsertClientNameHere, I can make those changes but I will have to increase 
the development time to X and that will add Z to the cost of the project. 
Don't be afraid to slap a good price on that Z, specially if you are far 
into the project. The client will do one of two things. He will either 
backdown and stick to the original design, or he will say OK(more money for 
you)! If he says OK then make an addendum to the contract and have him sign 
it. So the new time and price is agreed upon.

is it a one time deal or continued business...

I charge more for just building a website, but if I am going to maintain the 
site I then adjust for any hosting cost, then charge a 10-20% fee (of the 
total project build) for monthly maintenance/year (this will cover my time). 
I then will give a price break, usually of 10-20% off the total project 
price for maintenance as an added motivation to get it.

make sure you deliver
--
You reputation is of the utmost importance, do everything you can to meet 
your deadline.. If you can not complete part of a contract yourself then, 
outsource it. The client does not need to know and in most cases they don't 
care.

[PHP] Creating INSERT INTO statement from dbf file

[Rahul S. Johari]

Ave,

I¹ve written a code that is able to extract the Column names and Records
from a simple dbf (foxpro) file and create an INSERT INTO sql statement
which can be used to insert all those records with their corresponding field
names in an existing mySQL table. (A CREATE TABLE code I wrote is able to
create the table from the dbf file information).

Following is the code I wrote for creating the INSERT INTO sql:

";
   
}
}
dbase_close($dbh);
?> 

It works fine, except for one problem. It¹s able to create the INSERT INTO
sql statement, with all the fields and corresponding values, but as I¹m
running a loop for both the fields names, and the values corresponding to
fields names, it leaves a comma after the records are over.

So instead of having this : INSERT INTO tblname (c1,c2,c3) VALUES
(Œv1¹,¹v2¹,¹v3¹);
I achieve this : INSERT INTO tblname (c1,c2,c3,) VALUES (Œv1¹,¹v2¹,¹v3¹,¹);

Notice an additional Comma after column names, and an additional ,¹ after
the values. I¹m not quite sure what to do to get rid of those. I¹ve tried
some different combinations using different kind of logic with the echo
statements, but it¹s not working out. Would love some help.

[PHP] [Q] mail() & security

[Eric Gorr]

I wanted to setup a good 'contact me' page on my website. I do not want 
to reveal my e-mail address, so I was going to use a form.

The PHP script with the actual mail() function would define the To and 
Subject parameters, so these could not be faked.

I also plan to use a captcha.
The only concern I had was how to process the body text. Any 
recommendations?

One useful function would appear to be strip_tags, so no one could embed 
annoying or destructive HTML, etc. which I may accidentally cause my 
e-mail application to render.

Any other suggestions?

Maybe:

www.php.net/addslashes
www.php.net/htmlentities

Whatever you do don't strip out line breaks. I find it really annoying
when I neatly format (read "use paragraphs") a message in a contact form
just to find out that all those pretty line breaks are removed, turning
my nice message into a difficult to read blob.

Remember, the text being processed goes straight from $_POST[ 'body' ]

It would seem that addslashes would just make the body text look messy 
for no reason.

www.php.net/htmlentities
It seems as if strip_tags strip out everything that htmlentities would

Remember? You didn't mention this is your original email so how could I
be told to recall this information? In your specific case addslashes()
is probably not necessary.

> It seems as if strip_tags strip out everything that htmlentities would

strip_tags() and htmlentities() both perform seperate functions (hence
they have different names). htmlentities() encodes special characters,
strip_tags() strips HTML from a string. One example is the following:

Original: &

With strip_tags applied: &

With htmlentities applied: &

It may or may not be necessary for you.

[PHP] Help. Floats turning into really small numbers? x.xxxxxxxxxxxxxxxxxxxxxxE-xx

I'm having trouble figuring out why subtraction of two floats are giving
me a very small number.  I'm thinking it has something to do with the

can give me some suggestions, please.

I have 2 variables that go through a while loop and are
added/subtracted/ multipled. InvAmt and InvPay are shown as
floats but when they are subtracted, they give me a really small
number

// code
var_dump($InvAmt);
var_dump($InvPay);
var_dump($InvAmt-$InvPay);

// output

float(18.49)

I do not mind over doing it and potentially getting rid useful text in

[PHP] PHP Tool to answer emails

[Daniel Baughman]

Hi all,

 

I am looking for a php tool that will provide email tracking and a web
interface to an email box.  Pretty much, we get lots of emails directed to
an administrative email account (most of the valid emails) that need
response. To the point that one person is getting over whelmed.

 

It would be nice if someone had a tool already made that would check the
box, download the email, mark the receipt time, then present them to be
answered on a web site for employees, document the answer, etc. etc.. 

 

Anyone know of anything?

Nothing, but with htmlentities() you can be sure if the user has tried 
to inject something malicious :-).

Then just use strip_tags() and be done with it.

It's not like nuclear missiles are going to be launched via your email
form if you use the wrong function. Or in a less extreme case, your
computer get hijacked and used to send spam because you used
htmlentities() instead of strip_tags().

Well, this is why I asked the question to begin with. I am concerned (as 
everyone _should_ be) about such things and desire to do my best to 
prevent them.

Now, as near as I can tell, strip_tags is the only thing one really 
needs to do to be safe.

But, one can use htmlentities to potentially preserve useful text, if it 
is important to do so and still remain safe - with the downside being 
having a messier body then may be necessary.

Eric,

It sounds like you just need to do some reading on "best practices" of
security when writing php code.  It's pretty vast what one can do when
trying to hack a php application and depending on what php server
settings are set, you may need to do certain things.  I'd suggesting
reading / google php security and viewing pages like the following to
answer your question.  It may only answer your question in the long run,
but there are many more things to know about besides htmlentities to
make sure your application is secure.  I actually need to do some
reading about them.  Once in a while

http://www.devshed.com/c/a/PHP/PHP-Security-Mistakes/


Also events like the following are good to go to expecially if you can
get your company to pay for them.

Re: [PHP] Help. Floats turning into really small numbers? x.xxxxxxxxxxxxxxxxxxxxxxE-xx - Narrowed it down!

[Anthony Tippett]

Ok i've narrowed it down a little bit but still can't figure it out..

Here's the code and what I get for the output.  Does anyone know what's
going on?  Can someone else run it on their computer and see if they get
the same results?
"; // 18.49

var_dump($a);  // float(18.49)
var_dump($a-18.49); // float(3.5527136788005E-15)

Re: [PHP] Help. Floats turning into really small numbers? x.xxxxxxxxxxxxxxxxxxxxxxE-xx - Narrowed it down!

[Richard Lynch]

Floats are NEVER going to be coming out "even" reliably.

You'll have to check if the difference is less than X for whatever number
X you like.

Or you can look at something like BC_MATH where precision can be carried
out as far as you like...

But what you are seeing is to be expected.

That's just the way computers work, basically.

Re: [PHP] PHP Tool to answer emails

[Anthony Tippett]

I think what you are looking for is a combination of programs.  A
mailing list that customers can view answers of emails try mailman or
smartlist.  Perhaps just a mailint list would give you want you want.

If you are looking for more of a trouble ticket program, or FAQ program
there are serveral at freshmeat.net but haven't used many of them.

Re: [PHP] Help. Floats turning into really small numbers? x.xxxxxxxxxxxxxxxxxxxxxxE-xx - Narrowed it down!

[Anthony Tippett]

btw, thanks for your response.

I'm not sure as if I understand why.  It's not like I'm using a very
precise number when dealing with the hundreths place.

Even without the multiplication the number gets messed up.

eg.

$a = 17.00;
$a+= 1.10;
$a+= 0.32;
$a+= 0.07;


print $a.""; // 18.49

var_dump($a);  // float(18.49)
var_dump($a-18.49); // float(3.5527136788005E-15)

I'm just trying to add money amounts?  Can I not rely on floats to do this?

[PHP] Why do I have to declare __set if I declare __get for read-only properties?

[C Drozdowski]

Howdy,
I'd like to access some of the private members of my classes as 
read-only properties without resorting to function calls to access 
them. (e.g. $testClass->privateMember instead of 
$testClass->privateMember(), etc)

Based on my research and testing, using the __get and __set overloading 
methods appears to be the only way to do so. It also, based on testing, 
appears that these private members must be in an array.

What I do not understand is that if I declare a __get method I MUST 
also declare a "do nothing" __set method to prevent the read-only 
properties from being modified in code that uses the class.

For example, the code below allows me to have read-only properties. 
However, if I remove the "do nothing" __set method completely, then the 
properties are no longer read-only.

I'm curious as to why I HAVE to implement the __set method?
Example:

class testClass
{
   private $varArray = array('one'=>'ONE', 'two'=>'TWO');
   public function __get($name)
   {
   if (array_key_exists($name, $this->varArray)) {
   return $this->varArray[$name];
   }
   }
   public function __set($name, $value)
   {
   }
}
$test = new testClass();
$test->one = 'TWO';   // doesn't work
echo $test->one;  // echo s 'ONE'
?>

[PHP] Set session variable if link is clicked, do not want to use GET

[Kent]

Hi!
I am writing a simple shopping cart system which uses sessions and PHP.
I would like a normal link that says "Add to cart" which the user can 
click and the item is added to the cart.

However, i do not want to use GET for this as it could introduce 
unwanted features if the user bookmarks the page just after clicking 
"Add to cart". So i don't want an URL like: 
http://thisistheurl.com?buy=10 and therefore prefer if this could be 
done using POST.

It would have been easy if i would have used a normal FORM and would 
have had a button called "Add to cart". But i would like it to be in 
url-style or using some  which i understand that the BUTTON item 
does not support (or am i wrong?).

Any advice would be greatly appreciated.
Best regards, Kent

Actually, I am familiar with everything this document mentions.
Unfortunately, this document does not discuss what one might need to be 
concerned about when passing text to the body parameter of the mail() 
function.

If you have any comments with respect to this (which was my only concern 
in the original message), please let me know.

I haven't found any articles which addresses this particular issue, 
which is why I posted the question.

[PHP] Accented character 'echo'ed randomly

[John Coppens]

Hi people.

I submitted the issue below to the bug site, but the people there
suggested I present it here. I've tried some more, but until now, I
couldn't find any cause for the problem. 

Any suggestion would be appreciated!

John


Description:

I have a very simple web-page script with mainly 'echo' commands.
Randomly the accented characters are replaced
by question-marks. If or not the question mark appears
seems to be depending on the page contents, though at least
in one of the cases, the only thing that changes in the
page is a GIF image. 

All this happens in the same html-session, using the same
script.

I've seen other -similar- reports, though none about 'echo'.
I can't be sure if this is an apache problem or php-related.

Sorry if was already solved... Please indicate.

Reproduce code:
---
echo "Página Índice";

Expected result:

Página Índice

Actual result:
--
Randomly 
Página Índice
P?gina ?ndice

Re: [PHP] Help. Floats turning into really small numbers? x.xxxxxxxxxxxxxxxxxxxxxxE-xx - Narrowed it down!

[Anthony Tippett]

Thanks to everyone that helped.  After further googling, bug 9288 had a
good explanation of what was going on ( which is not a bug)

http://bugs.php.net/bug.php?id=9288&edit=3

I'll just include the answer for anyone that comes upon this tread on a
search engine.


[15 Feb 2001 2:55pm CET] hholzgra at php rot dot fot net

short answer:
never use floats or doubles for financial data!

longer answer:
the internal number format in modern computers
is binary (base 2) and not decimal (base 10) for performance
and complexity reasons
while it is possible to convert decimal numbers into binaries
and back this does not hold true for fractions
something like 0.3 (decimal) would be a periodic binary
fraction like 10/3 is 0....
in decimal
this leads to loss of precision when calculation with
decimal fractions as you have when storing currency values

solution:
if you just summ up values then you should store values in
the smalest unit your currency has (pennies?) instead of
what you are used to (Pounds?) to totally avoid fractions

if you cannot avoid fractions (like when dealing with
percentage calculations or currency conversions) you
should just be aware of the (usually very small) internal
conversion differences
(0.27755575615629 in your example)
or use the bcmath extension, although for monetary
values you should go perfectly fine with using round(...,2)
on your final results

[PHP] Re: PHP Tool to answer emails

[Manuel Lemos]

Hello,
on 04/04/2005 08:56 PM Daniel Baughman said the following:
I am looking for a php tool that will provide email tracking and a web
interface to an email box.  Pretty much, we get lots of emails directed to
an administrative email account (most of the valid emails) that need
response. To the point that one person is getting over whelmed.
 

It would be nice if someone had a tool already made that would check the
box, download the email, mark the receipt time, then present them to be
answered on a web site for employees, document the answer, etc. etc.. 

 

Anyone know of anything?
Probably the simplest way to get you started is to make those messages 
drop in a mailbox accessible by POP3 . Then you can use a POP3 client 
class like this to fetch the messages that you for your own processing:

http://www.phpclasses.org/pop3class
If you want to generate automatic responses, you may want to take a look 
at this other class too:

Button images are fine:
http://www.mompswebdesign.com/html/button_tag.html (just picked that
one at random).

Another option is to set a unique SESSION variable each time they
visit, and that unique variable is only good during that session. You
pass that variable in the GET request and then match it on the
following page. If they don't match then you know they bookmarked it
or fudged the GET request.


Cheers,
Leif Gregory

you can use POST with some javascript tricks.

lets assume that you are going to you an image file to submit, then just add
a function andd call that function to handle submitting data.
