[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 internals of type casting, but i'm not sure. If anyone has seen this or 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) float(18.49) float(2.1316282072803E-14) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] [Q] mail() security
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. http://www.osevents.com/page5.html? Eric Gorr wrote: Chris W. Parker wrote: 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. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] PHP Tool to answer emails
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!
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=9288edit=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 Anthony Tippett wrote: btw, thanks for your response.

[PHP] Setting or Getting Relative Path for PHP Includes
Hey Folks, Hoping someone can aid me with a newbie-ish question. I often use PHP includes in my files to pull in assets, but I hard code the relative path to the root html directory for the sites that I'm working on in each file. Example below: ?php $path = '/home/virtual/sitename.com/var/www/html/'; //relative path to the root directory $inc_path = $path . 'code/inc/'; //path and folder the code includes folder is located $copy_path = $path . 'copy/'; //path and folder the copy is located ? I'd like to be able to set the relative path as a global variable from an external file so that I can modify one line of code to change the relative path across the site. This will allow me for easier coding in staging and development environments. What's the best way to do so? Can anyone provide a code example? Either that, or is there a way to call this variable from the server itself so that it's automatically -- and correctly -- set?

[PHP] apache2 php stability

Re: [PHP] apache2 php stability
Apache2 is multithreaded and works better under higher loads with a smaller memory footprint. If you have 300 simul connections under apache 1.3 you need 300 forks. The same load under apache 2 runs under 300 threads. With Linux 2.6 threads are very lightweight and in terms of system resources very inexpensive to start. Under a high load spike Apache 2 would, in theory, respond better.

[PHP] Specifying Variable Document Path in PHP
Hey Folks, My first post to this list and forgive me if this is ground that's been trod before, but this has been bugging me for a bit. I'm developing a site that's going to be running on a staging environment and a production environment. Have a number of PHP includes in the production site that specifically call the file pathname (thus): ?php include '/home/production_site/public_html/pagename.php' ? The problem here is that the path will vary slightly depending on whether it's the staging server or production server. I'd ideally like to set a single global variable that can handle this so I don't have to hard-code paths across the site (as I'm doing now). Is there any easy way to accomplish this?

In strcasecmp() - this comparison will return 0 - interpreted by PHP as
FALSE - eventhough words are _equal_ so what will execute is words are not

whereas if the negation symbol of ! is inserted as in:

[PHP] php textbook
Reading Creating Interactive Websites with PHP and Web Services (Sybex) by Eric Rosebrock. I've found it a good textbook and wanted to get some feedback from the group about two things I noticed in most of the code throughout the book which has helped me. 1. The author separtares .html form from .php script by using many include() functions for the .html files. I have found that that helps from getting parse errors from the many escaped strings throughout the .html within a .php file if the coder can separate the .html markup from the backend script as much as possible. Kind of like CSS which can separate form from content. 2. The author makes use of many switch() constructs throughout the book as opposed to if / else. He brings in variables from query strings when the user submits the .html form to match the switch() contructs which then decides what action will follow. Anyway, I found the textbook a nice change in the way he presented his scripts and thought others would like to share any feedback if they have read or are reading the book.

[PHP] session looses variable
Hi,
This is what is probably a newbie session problem.
I've been having some trouble with sessions on php 4.0.6, I'm developing
a website in which I don't have direct control over the server. Due to
some other problems I created a test counter script to try to narrow
down where the problem resides but no I'm sort of stuck.
Here is the small counter script.
session_start();
print_r($HTTP_SESSION_VARS);
if (!session_is_registered('count2345')) {
$GLOBALS['count2345'] = 0;
echo create countbr;
session_register('count2345');
} else {
$count2345++;
}
echo br;
echo session_id();
session_write_close();
When I refresh it will periodically loose the count2345 session variable
and recreate the variable. At times it will also jump in value.
Here are also the php configuration session settings.
session.auto_start Off Off
session.cache_expire 180 180
session.cache_limiter nocache nocache
session.cookie_domain no valueno value
session.cookie_lifetime 00
session.cookie_path //
session.cookie_secure Off Off
session.entropy_fileno valueno value
session.entropy_length 00
session.gc_maxlifetime 1440 1440
session.gc_probability 11
session.name PHPSESSID PHPSESSID
session.referer_check no valueno value
session.save_handler files files
session.save_path/tmp/tmp
session.serialize_handler php php
session.use_cookies On On
Here is also the compile configuration which includes --enable-trans-sid

[PHP] Calendar math .... how to count in week days....?
I've run into a bit of a problem, that I know has been dealt with before, but I don't know how to deal with it. Very simple, I have an application that needs to do calendar math and do it specifically on business days. I need to be able to add and subtract a number of days to only Monday though Friday. Seems simple enough, but I can't figure out how to do it. The only think I've come up with so far is to build a function that counts every day and checks to see if it's a weekend or not. This wouldn't be all that hard to do, but I'm wondering if there is a better way to do it? Anyone have a really efficient function to do this, I need to figure out a LOT of dates in this app. - Anthony -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] form textbox with search
Greets,
The following code snippet receives data from a textbox named searchtext if
the user types in a word.
It then tries to match that word from the mysql database using:
$searchtext = $_POST['searchtext'];
if ($searchtext != '') { // Some search text was specified
$where .= AND blurb LIKE '%$searchtext%';
}
and adding on to the WHERE sql statement.
If the user clicks the submit _without_ inserting a word, the whole database
is output due to the basic select sql statement of:
$select = 'SELECT DISTINCT merch.ID, merch.blurb, merch.price';
$from = ' FROM merch';
$where = ' WHERE 1=1 ';
I am trying to work out a way to display a page that might say - Please
enter a word if the user fails to insert a word in the textbox.
Any help greatly appreciated.

[PHP] session / garbage collection problem
PHP Version 4.2.2 Apache 2 RH 9 The problem is that session files in the /tmp directory are completely cleared out at random intervals of time. We assume that the randomness is due to our session.gc_probability setting of 1 causing it to run for 1% of new sessions. What we don't understand is why the garbage collector is removing valid sessions. session.gc_maxlifetime is set to 86400 (24 hours) so it should keep them around for a good long time. However, it seems that ALL session files are deleted when the garbage collector runs. In some cases session files were deleted for sessions that had been around for less than a minute.

Re: [PHP] session / garbage collection problem
Well, we host our own so what I was thinking wouldn't quite work for your situation. However, I've seen a method that I think would work pretty well for you. Basically, you store all the data you want to be persistant between requests in a database. You could use the session id you get from the browser as the key for a sessions table. So, getting session data looks something like this: $sess_id = session_id(); $result = SELECT * FROM sessions WHERE session_id = '$sess_id' Since session_id() gets it's information from the HTTP request, and the browser keeps the session cookie (at least it does in our case), you don't rely on the stuff in the tmp directory at all. You could also emulate PHP's session-in-file approach using a similar method.

[PHP] $_SESSION var sometimes set, sometimes not
Hi,
The following code sometimes produces output indicating that the session
variables have been set, and sometimes is says that they have not been set.
Unfortunately the server is not mine to configure, but if there is a problem
with it, I can get in touch with the right people. Is the script properly
written? Is it a server problem?

I just tried that. It made no change. Still sometimes works, sometimes doesn't. It's on the order of clicks. It may work three times in a row, then fail a couple times. It's very strange. John W.

[PHP] file paths and binaries
Greetings all, I'm looking for a tutorial or some assistance in explaning how store and then open and read a binary file using php/mysql. I've got a few tutorials about storing the binary data _within_ a mysql table from Kevin Yank, phpbuilder, etc. but I've heard that it's sometime better to keep your binaries on the server and not in the database. Thus, if the developer just keeps the file path in a VARCHAR column like: C:\apache\images\house.jpg C:\apache\images\tree.jpg etc... and then directs that file be fopen() fread(), etc. it will work without the added overhead. I'm a bit lost in what happens after the filepaths are inserted into the database and what steps follow in the script so that they can be opened and read. Any help, URL's or tutorials will be of assistance. Thank you. TR -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] download from mysql script
I'm trying to receive data from a mysql database through php.
Using the command line at mysql listed below gives me a result set.
I am able to connect to the database through php, however, when using the
following script, I receive no data when the data is in the table called
pictures in the db called sitename.
?
if($ID) {
@MYSQL_CONNECT(localhost,root,thepassword);
@mysql_select_db(sitename);
$query = select bin_data,filetype from pictures where ID=$ID;
$result = @MYSQL_QUERY($query);
$data = @MYSQL_RESULT($result,0,bin_data);
$type = @MYSQL_RESULT($result,0,filetype);
Header( Content-type: $type);
echo $data;
}
?
// In browser window it reads:
// http://localhost/download.php?filename=7
//...and on the Command Line using the following query:
// SELECT filetype FROM pictures where ID=$ID
// gives me a image/pjpeg as the result set.

Re: [PHP] =sessions / J. Meloni Textbook=
Thanks again but here's what happens when I run that. The form box appears. I select an option. I hit submit. The page that loads says: Warning: Invalid argument supplied for foreach() in c:\apache\htdocs\session_yyy.php on line 13 I then hit the link: Back to content page. The form box appears. I select _another_ option. I hit submit. The page that loads now has the _second_ value I have submitted but not the first. Like: 1. 2. Hal 2000 Is there a way to get the first option into the array? If you get a chance please try the code. Thanking you for your time. TR .. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] =sessions / J. Meloni Textbook=
Sure.
Here it is.
There are three scripts.
session_1.php: the original form script.
session_1a.php: a revised script with a conditional else.
session_2.php: the receiving script for the session array variable.
Running script 1a and 2 works fine.
However the original script 1 and 2 gives me a error when returning to the
contents page the first time - it then fills the contents starting with the
number 2 on subsequent page loads.

1.
2. Hal 2000
3. Sonic Screwdriver
Try it and see and let me know.
Thank you.

[PHP] naughty words / filter
Hi,
I'm trying to filter a word - in this case - called badword1 - to be
replaced
with asterisks.
Listed below is my .html form and .php receiving script.
I've also added the same script which gets a hardcoded string.
In the first example, the output still shows the original message _without_
replacing the badword whereas in the second example with the hardcoded
string - it is getting replaced with *.
Any assistance would be greatly appreciated.
Thank you.

Move the above line outside of your while loop
$row_color = ($posts_info % 2) ? $color1 : $color2;
$row_color = ($posts_info++ % 2) ? $color1 : $color2;
You were setting $posts_info to zero in each loop, so it's never going
to change. You must set it to zero outside of the loop, then increment
it within.
You could make this real easy and just do:
$row_color = ($row_color == $color1) ? $color2 : $color1;

[PHP] discussion forum from j. meloni's book
The following code is From Julie Meloni's textbook - PHP, mySQL and Apache
(SAMS) on page 305-307 / Listing 14.5:
It's the last script of a discussion forum which is comprised of four php
files and one html file.
The script can be seen at:
http://www.thickbook.com
Chapter 14 off the zipfile.
Anyway, in the textbook and the zip her mySQL query reads:
...
$verify = select ft.topic_id, ft.topic_title from forum_posts as fp left
join forum_topics as ft on fp.topic_id = ft.topic_id where fp.post_id =
$_GET[post_id];
.
The part that I'm confused about is:
...
select ft.topic_id, ft.topic_title from forum_posts
It seem that the alias of ft refers to forum_title - not forum_posts.
In fact, I switched the query to read as follows:
$verify = select ft.topic_id, ft.topic_title from forum_topics as ft left
join forum_posts as fp on fp.topic_id = ft.topic_id where fp.post_id =
$_GET[post_id];
..
And that seems to run fine.
Any explanations will be appreciated.
Her original code is below.
Thank you.

[PHP] Re: Strange Problem
You'll get this in IIS if you request a page that should be parsed by the PHP CGI that does not exist. IIS trys to load the script into the CGI but gets no results since there was no page to load. I think it's an IIS bug i.e. you go to www.domain.com/page1.php but there is no page1.php file. So you'd expect to get a 404 error. but IIS gives you the CGI error instead. Kinda sucks, I just use Apache now anyway, so I never spent the time to figure out why. - Anthony Haseeb [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi all, this is a very strange problem. i don't know where i am doing something that is causing this. the problem is that i am working on a web portal entirely in php. i have a few hidden pages. that do the queries to the DB. now when i redirect to any page for query i get this error CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are: strangely when i hit F5 or refresh the page i get redirected to the desired page. i have checked for any whitespaces. there are none. i have checked and double checked this. i am using win2k,IIS, php 4.3.0 again i have checked all the files for any space left that could be causing problem but i found none. i hope i make my self clear.

Thanks for the links, I'm going through them now as far as the location thing.

Re: [PHP] Please dirrect me -- headers ????
yes, I can edit the httpd.conf file. I'm looking in the Apache 2.0 docs and can't find the server directive. Also, to my knowledge and according to the docs, alias mydom.com is invalid. Alias URL-path file-path|directory-path is how the docs explain it. Am I missing something. If I can do this through Apache. it would probably be much simpler. - Anthony Apache 2.0.45 by the way :) Taylor York [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Cant you edit the httpd.conf?

[PHP] Re: Please Help !
look up two functions in the online manual. strtotime() and date() strtotime will give you a unix timestamp for just about any date possable, date will format it the way you need. to get it into a mySQL date field, basicaly, you do this: date(y-m-d, strtotime($_POST['date'])) where $_POST['date'] is whatever variable you used. - Anthony Sean O'Reilly [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, I know this is really basic but i have a form for users to enter the date of an event that i would like to store in a mysql database how do i get the users input into the database in the right format. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: php my sql question
When you upload the page to the webserver and then access it, do you just see the source? If so then you probably don;t have PHP support as part of your hosting package. Call your web host and find out. Also, if you're really new to PHP, I'll through this out too, you did put ?PHP ? arround your script right? Once you're sure PHP is running, then check out the online manual for MySQL functions -- http://us2.php.net/manual/en/ref.mysql.php You don't need PHP on your local machine, just on the webserver. It may be a good idea though to install a webserver (like Apache) and PHP on your local machine, that way you can test your scripts without uploading them to the webserver. - Anthony Jerome A.

[PHP] Re: Calculating Largest Member of Array
why not just change your array structure a little so that the date is the
key, and the elements are the values. so it would look like this.
Array
(
[Jan-99] = Array
(
[0] = 6399.36
[1] = 6132.71
[2] = 2242.20
[3] = 53.27
[4] = 87.34
)
[Feb-99] = Array
(
[0] = 5754.72
[1] = 3964.93
[2] = 6145.98
[3] = 693.32
[4] = 23.80
)
)
That would make it much easier. I think.

So far this is how I'm doing it, but sometimes I get returned a month for

I believe I read they use this info to transfer money from your bank account, after convincing you to scan your passport for them, or something like that. Actually, the scam is fairly sophisticated. They ask for money upfront in order to begin the process of getting access to the loot that is stored whereever. Usually, they ask for one or two more payments, since it is costing them more than they thought. They then inform you that the money you sent them has been used to bribe officials, including those in the government. If you don't send them even more money, they will report you to the authorities on suspicion of bribery and have you arrested. At this point, the scam becomes simple blackmail. Most interesting to me is that this scam is so widespread (a sign that it is successful) that the FBI has stationed some agents in Nigeria solely for the purpose of dealing with this scam.
