Hello,

My understanding from the documentation is that the fmod() function should
work with floating point numbers however the following snippet of code:

<?php
//php 4.3 on Linux

$x = 1.05;
$y = 0.05;

echo "x: $x <br>";
echo "y: $y <br>";
echo "fmod: " . fmod($x, $y) . "<br>";

?>

outputs the following:

x: 1.05
y: 0.05
fmod: 0.05

I would have expected to get an answer of 0 i.e. no remainder. It works fine
for whole numbers.

Can any one shed any light on this please?

Thank you.

Regards,
Andy

P.S. I tried using the following function but I get the same results:

function fmodAddOn($x,$y)
{
       $i = floor($x/$y);

       // r = x - i * y
       return $x - $i*$y;
}

Hi There,

I'm a bit of a newbie here I'm afraid so I'm sorry if this is an obvious
question.

I have a script which read includes an html file. The html makes a call
so a function in the main script. This call passes a string which
includes variables i.e. : <td>$title</td><td>$name</td>

in the function that gets called the variables $title and $name get
populated with values and then the script echos the html string to the
client.

The problem is that the variables in the html string get evaluated at
the point it is passed into the function not as the point it is echoed.
Can anyone help?

Thanks

> I currently run a few newsletters that go out to small groups of
> % 50 to 100 people. I use a while loop to send out the emails. I chose

   I have a module that does about about 100 emails (10Kb of data per email, which is a decent sized email) in 8 - 10 seconds. (Does around 610 - 625 emails per minute). This is accomplished by skipping PHP's internal mail functionality entirely and making a direct socket connection to the SMTP server. Another benefit of this is that any MySQL delay can be removed from the actual mail functionality by adding all the recipients to the class, and closing the MySQL query - before sending the emails. Ultimately, the speed really depends on the SMTP server. I'm sure with a little hacking, I may be able to get 650 - 675 emails per minute.

   One faster method of sending bulk emails requires A) having direct access to the filesystem of the mail server, and B) hacking sendmail configuration - which both mean "root" access. I've gotten up to 850 emails per minute with this method.

   The class is easy to use - basically:

$_Mailer = &new mod_sendmail();
$_Mail->setSubject( strText );
$_Mail->setBody( strText );
$_Mail->addRecipient( strName, strEmail );
$_log = $_Mail->sendAll();

The $_log var is an array in the format of:

$_log[ strEmail ] = strData

strEmail is the intended recipient, and and strData will either be A) the MsgID returned by the SMTP server on success or B) a "0" if failed. This makes it possible to add a function to re-send failed emails later.

   If you want the socket-based code, just send me a private email to kodekodekrash.com. I'm working on getting a code repository going, but for now, just have to send it to you directly.

Hola, PHP folk-

I am using

$page_title="some page title here";
require('header.inc');

to include a common header for all my pages. I am using $page_title so
I can have unique names for the different pages.

//---header.inc
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
   <head>
     <title><?php echo $page_title; ?></title>
     <link rel=stylesheet href="./some.css" type="text/css">
   </head>
<body>
...

I want to be able to also define the path to the CSS file. For
instance, some pages will have the CSS in the same directory, so that
part would read

"./my.css"

If the page is located in a subdirectory, the path would then be

"../my.css"

I would like to use a php variable where I can define the path the same
way as the $page_title works. I have tried some experiments with a
$path_to_css variable, but I have not had much success. I think part of
the problem is that I might be stumbling over escaping everything properly.

Is there a better way to do what I am trying to do?

Thanks,
Danny

I personally link my css files using the root dir...

The way my server is setup it depends on your web root dir. If your css
dir and file are located in:
/userid/public_html/css/css1.css

My web root is:
/userid/public_html/

So the path I would use to get to the css file is:
/css/css1.css

Okay, I got my pathname straightened out, but I'm still showing the

But that's after doing $[var name] = $_POST['var name']; for everything

Have I got this right?

I am doing

<?php
        $BRPHP = $_SERVER['HTTP_USER_AGENT'];
        $arr = array (1 => "$BRPHP" );
        exec (' ../cgi-bin/browser.pl', $arr );
        echo $arr[2];
        echo $arr[3];
        echo $arr[4];
        echo $arr[5];
        echo $arr[6];
?>

1. Am I passing $arr[1] to the perl script?
2. If no, what should I do instead?
3. If yes, how can I access it from the perl script?

(Yes, I know the last question is a perl question, so I'll be happy to just get an answer to the first two).

Thanks,

I'm new to php and am trying to create a very basic content
management system to let my client update a popup on their
homepage. I'm using mySQL and have a good idea of how to do
the login and set & read cookies, as well as accessing the
database during the admin process.

The part I'm not too clear on is how to implement the front
end for the general users. When someone visits the site and
the popup pops up, what happens on that page? Does it access
the database at the time it loads to load the information?
If so, is this possible without hardcoding the
username/password information (to access the database) in
the popup page code?

Is there a tutorial or article on stuff like this somewhere?

Problem with looping over a CSV file (3 results for each line)? Here is
the CSV file contents...

MTPC-01,00:02:B3:A2:9D:ED,155.97.15.11
MTPC-02,00:02:B3:A2:B6:F4,155.97.15.12

$id = fopen("$file","r");

Hi,

attached is a php/java bridge which uses sockets to communicate with
java instead of creating a new JVM for each request.

The protocol that is used is very simple but efficient and the
Apache/PHP/JAVA solution should be as efficient as Apache/Tomcat/Java
for example.

This module is based on Sam Ruby's original java code, but it is easier
to install.

Not sure either. Did you have a question?

Hello, I have wrtten a PHP based web site with a MySql backend and now I
want to password protect downloadable files. I have logon and session
handling taken care of but I can't figure out how to only allowed those who
are currently logged in and above a certain security level to access the
downloadable content and prevent bookmarking of the file location for
redownloading.

Currently I have a .htaccess file to protect the files but then you need to
enter a User ID and password a second time. I would prefer a single signon
solution.

I have considered copying the files to a temporary area each time someone
wants to download it and then erase it when the session is killed but these
files can be large (20-100 mb) and I would rather not do all of that copying
if possible.

Creating unique symlinks would be easier but my development machine is
Windows and my server is FreeBSD and I can't create file links under
Windows. Plus, my FreeBSD server is not near me so remote development is
difficult.

Thanks to anyone with any ideas,
Andrew

1) windows has symlinks since win2000, however they are named Junctions.
   I would recommend visiting sysinternals.com and getting junctions
   tool (win2k/xp/2k3 -> miscalenous). Hey, it even comes with source!

2) another way is to make a redirect, so you do:
   getFile.php?file=something.zip

   and in your code you do:
   <?
     include "_mylibs.php"
     if (userLoggedIn())
         header "Location: ".$_REQUEST["file"];
     else
         echo "Only Valid People Can Login";
   ?>

3) final way is to pass through the file yourself. Safest way, but
   potentially more resource hungry than the two above
   in your code you do:

   <?
     include "_mylibs.php"
     if (userLoggedIn())
     {
        header("Content-type: application/octet-stream");
        header("Content-Disposition: attachment; ".
               "filename=".$_REQUEST["file"]);
        readfile($_REQUEST["file"]);
     }
     else
         echo "Only Valid People Can Login";
   ?>

  freshmeat , and search for anti leecher scripts.

I would go for the 3rd alternative. There are several ways to
"stream" the file with the use of headers.

This way you can validate the user securely with your logon system,
and you can place the files outside the viewable web content.
Typically oputside your www / public_html folder.

I use this myself in an application I use, streaming files at 50MB
does not use alot of resources at all, atleast not the way I use.
My use for the script is to serve high resolution images to several
customers, often TIF images up to 50MB and larger.

Heres the code I use :

$distribution= "filepathonserver";
if ($fd = fopen ($distribution, "r")){
    $size=filesize($distribution);
     $fname = basename ($distribution);

    header("Pragma: ");
    header("Cache-Control: ");
    header("Content-type: application/octet-stream");
    header("Content-Disposition: attachment; filename=\"".$fname."\"");
    header("Content-length: $size");

     while(!feof($fd)) {
          $buffer = fread($fd, 2048);
          print $buffer;
     }
     fclose ($fd);
    exit;
}

You could have your authorization info in the mysql db including file
locations that are stored along with the authorization level necessary to
download them. If the person is authenticated to download the file, the php
script uses the file location info from the db to open the file and generate
the headers necessary to start the download. This way the end user never
has to have direct access to the download directory and you don't have to
copy the file into a temporary directory.

I used to program in Miva some because it was fairly easy. I got used
to using some things and was wondering if there is a PHP equivalent.

<MvIF EXPR="{submit}">
  <MvLET assignedto="(Unassigned)">
  <MvASSIGN NAME="help" VALUE="len(description)">
  <MvASSIGN NAME="bugnumber" VALUE="{random(1000)$time_t$random(help)}">
  <MvLET description=glosub(description,asciichar(13),"<BR>")>
  <MvASSIGN NAME="" VALUE="{fdelete('temp.dat')}">
  <MvEXPORT FILE="temp.dat"
FIELDS="bugnumber,subject,description,reporter,assignedto,state, id"
DELIMITER="|$%">
  <MvIMPORT FILE = "buglist.dat" FIELDS = "bugnumber, subject,
description, reporter, assignedto, state, id" DELIMITER = "|$%">
    <MvEXPORT FILE="temp.dat"
FIELDS="bugnumber,subject,description,reporter,assignedto,state, id"
DELIMITER="|$%">
  </MvIMPORT>
  <MvASSIGN NAME="" VALUE="{frename('temp.dat','buglist.dat')}">
</MvIF>

The first MvEXPORT would at a the new data to the top of the list. The
the MvIMPORT with the nested MvEXPORT would add the rest of the data to
the list of data. I've been looking through my PHP book and only see
how to use databases in it. I was wondering if there is a way to save
something like this without the use of a database. I plan on making a
few form mages that are going to save some data, but like 3 or 4 entries
each. Since my webspace limits the number of databases, i'd rather do
it without the use of that.

My second question is about including pages.

would
|<?PHP include 'menu.html'; ?>
include the file the same way a SSI include would?

Thanks.

Hello list..

I was needing a small hint on how to make a sort of status page...

What I have is a function that takes a few minutes to complete...

It send an snmp signal out then waits a bit and then gets the status via
snmp.

I would like to have some sort of graphic or page for the status, e.g.
Percent done, a flashing waiting or something.

How might I do this?

A quick thought would be to use flush() http://www.php.net/flush to send
output to the browser.

This was posted to Slashdot not too long ago, and seems applicable to
php-general given the frequent mentions of register_globals and usage of
the get and post arrays. It's a detailed explanation of many common ways
that software which is overly trusting of its input can be exploited, and
underscores the point that input from the open internet is particularly
risky.

http://www-106.ibm.com/developerworks/linux/library/l-sp3.html

A lot of the article deals specifically with writing applications in a
Unix environment, but the general take-home points for PHP programmers
boil down to:

- In a client/server system, the server should never trust the client.
- Ruthlessly check untrusted inputs.

Hi,
I am not sure how to go about this. =( I think my problems are twofold.

problem 1. I have to connect to a progress database, for which there is
no built-in php
support. I have been looking at the unified ODBC functions, but progress
isn't
one of the supported dbs there either.

problem 2. the db is not specifically a web db. It is the clients'
production db that
is located on their facility and it is behind a firewall. I know I will
get a performance
hit with this setup, but I can live with this.

question 1: do I need a progress driver, or do the ODBC functions take
care of that?
question 2: is it possible for the db connection to get thru a firewall,
and then connect
            to a db?

TIA,
Craig

Sorry!

Here's a better example to what I meant from the last posting when I said
something about color=red#RowNum3.

--snip--

//Example #1

<a href="http://www.yourserver.com/yourpage.htm#RowNum3"
target="doc">Jump</a>

//Example #2

<a href="http://www.yourserver.com/yourpage.htm?color=red&color1=blue"
target="doc">Jump</a>

//Example #3

<a href="http://www.yourserver.com/yourpage.htm?color=red#RowNum3"
target="doc">Jump</a>

--snip--

As in example #3, PHP seem to be able to distingush the difference when
there is a pound symbol, or "#" in it and know that '#RowNum3' is not part
of the post string to the variable, color. So we get this

--snip--

color --> red

--snip--

And not this...

--snip--

Color --> red#RowNum3

--snip--

Cheer,

Scott

Hi!

     I'm encountering an interesting situation. I can do with one file path
in a flag for the compiler without a problem, but with 2 file paths in one
flag. What is needed to combine those two paths into one flags?

LDFLAGS='-L/usr/local/ssl/lib'

Some one is asking me to create a sub search on a search that has already
been done. For instance, the database has 50,000 records, a user does a
search for two keywords which yielded 1700 records. They want to now filter
that list with other keywords. The logic is that searching 1700 records has
got to be faster than searching 50,000 records.

The only way I know how to do this is to save the results of the pervious
search to hidden fields and allow the user to add more keywords, which in
essence isn't doing other than adding more keywords to the search doing the
same exact thing they did before with new keywords. Is this logic correct or
is there a way to save that queries results and search only that?
