Yes, you are right. I guess the category did not exist when the class
was contributed. Usually, the authors propose new categories. If the
author had proposed that category then, it would have been classified
properly. There are certainly many more classes that are not in all
categories that they should, awaiting for somebody to classify them better.

I have added the class to that category now. Thanks for the suggestion.

Now, use SELECT is simple enough. The Select Name gives a value, the one you selected of course...

However, I yet have to find a way to actually determine how I could fetch i.e. the results from a SELECT multiple-choice menu.
What if I want the website visitor to choose from multiple values, and read them in a PHP script after the form is submitted?

Suggestions or ideas of how to solve this?

I figured this is probably a very easy task, but I've done a couple attempts, and yet unsuccessful... I can make and read the values of multiple checkboxes, but I cant figure out how to do this with a select ...

This question was just asked a few hours ago, on this very list (not to
mention the few times a week). Anyway, since the list archives /must/
be broken....

<select name="whatever[]" multiple>
        <option value="thisValue" />Choose
        .....
        <option value="thatValue" />Choice
</select>

Now, putting the square brackets after the name of your form element,
will pass the results as an array, which will now be available to your
php script as....

$_POST['whatever']

It will be an array, even if only one option is selected, so please
treat as such.

I think I already asnwered this today....

Now the values the user selected will be in an array, $foo,
$_GET['foo'], $_POST['foo'], $_REQUEST['foo'], etc...

Hi all..

Right now, I am trying to do generation of report using PHP in which the
report should be in a printable format later on.

Is there any solution to use PHP to accomplish such task??

The report is viewed in a web browser and how should I create a navigation
link or something whereby user can click on it to view it in a printable
format and print it ??

Another example site which demonstrate such feature would be:
-->http://www.devshed.com/Server_Side/PHP/patUser/patUser1/page1.html

All help are greatly appreciated. Thank You.

Regards,
Irin.

How do you define a "printable format"?

Ideally, you want to do this in CSS. The "print version" would just load
a differnet style sheet than the main format.

You can also do it with PHP, like conditionally including / excluding
blocks, changing colors, fonts, sizes, etc....

I second John's "How do you define a "printable format"?"

I like his plan and just wish to add that you could create printable
PDFs using PHP.

I could use a little help. click on the link to see my php code for a
project that creates an array with a list or items and their cost and
calculates tax by using a function called getTax() and also creates a
balance by adding the cost plus the tax in a second function called
getBalance(). I must also create a table where the cells automatically
load so the end result looks like this.
http://www.areawebdirectory.net/taxtable2.txt

Item Cost Tax Running Total
Car 10000.00 600 10600.00
Pencil 1.00 .06 10601.06
Book 14.95 .097 10616.98

I cant seem to first be able to declare my array and succeed at naming
the key as item and the value as price. I have attempted to use
variations of the following with no success.

$items = array (
    0 => array ("item"=>"car","price"=>15000, "tax"=>.065 ),
    1 => array ("item"=>"pencil","price"=>1, "tax"=>.065 ),
    2 => array ("item"=>"book","price"=>14.95, "tax"=>.065)
);

Without being able to declare the key as item and the value as price I
am not sure how to pass these items into my function and I am riddled
with error messages. I think my base problem is to either fix how I am
declaring the array so I may reference "item" and "price" as I am now
doing in my functions or learn how to change the functions accordingly.

I am also pretty sure that my functions are not quite right. I am also
not sure how to link the right answers to get my table to print as above.

Please note that I have included a while loop after my array just to
prove that my array is working. It is needed part of my program. I also
have given each cell in my table some text just so I can find them when
I have figured out how to create the right reference links.

I am sorry that I need as much help with this. Sadly I have been at this
for almost two weeks trying to solve it.

Thanks,
Sara

Hi,
Little semantic correction, the function "GetBalance($item)" should be
called "GetFullPrice($item)" because it returns full price of the item, but
the "$balance" variable seems to be partial sum of the current item and
previous items;

First off, please try to refrain from cross-posting, especially to that
degree.

I'm not sure I interpreted the your intentions correctly. If not, could you
try to be a little more precise in saying what you _want_ the code to do?

The first thing that jumps out at me is in the function getTax. Shouldn't it
be getTax($value)? As you have it, value will be unset (search for variable
scope in the manual). I think this may be what you're going for:

function getTax($value) {
return ($value * 0.065);
}

Next, the list construct will only work with numeric arrays, not associative
ones. In other words, it has to look like array('one', 'two'), not
array('one' => 'two', 'three' => 'four')

Next the way you have it set up, $mypurchases can only contain one set of
three items. I don't get the logic of how car, pencil, and book map to $key,
$value, and $tax.... Maybe you were going for

$mypurchases = array(
        'car' => 15000,
        'pencil' => 1,
        'book' => 14.95);
$total = 0;
echo '<table><tr><td>Item</td><td>Cost</td>';
echo '<td>Tax</td><td>Running Total</td></tr>';
foreach ( $mypurchases as $key => $value) {
        $total += $value + ($tax = getTax($value));
        // assuming you want the table in HTML, since you have a <br/>...
        echo "<tr><td>{$key}</td><td>{$value}</td>";
        echo "<td>{$tax}</td><td>{$total}</td></tr>\n";
}
echo '</table>';

???

I'm going to ignore the getBalance function because I don't think it's
required. But you realize your declaring a static variable, then trying to
assign a different value to it on the very next line?

Using this array you need something like this

<?php
$items = array (
    0 => array ("item"=>"car","price"=>15000, "tax"=>.065 ),
    1 => array ("item"=>"pencil","price"=>1, "tax"=>.065 ),
    2 => array ("item"=>"book","price"=>14.95, "tax"=>.065)
);

function getTax($cost,$taxrate){
return $cost * $taxrate;
}

echo '<table border="1">';
echo '<tr><td>Item number</td><td>Item</td><td>Cost</td><td>Tax</td><td>Total</td></tr>';
$total = 0;
foreach($items as $key=>$item){
  echo '<tr>';
  echo '<td>'.($key+1).'</td>';
  echo '<td>'.$item['item'].'</td>';
  echo '<td>'.$item['price'].'</td>';
  $tax = getTax($item['price'],$item['tax']);
  echo '<td>'.$tax.'</td>';
  $total += ($item['price'] + $tax);
  echo '<td>'.$total.'</td>';
  echo '</tr>';
}
echo '</table>';
?>

You will need to add number formatting but you get the idea.

That's virtually impossible with modern operating systems. They are mysterious
beasts that will often write data to hard drive when you don't want it to.
Swap files are a particularly good example of how it happens.

You can play with popen and pipes (even named pipes could be useful), but
seriously there's going to be data written to disk. IMHO you'd be much better
off just writing the data in a predictable manner, then using something like
THC's SecureDelete.

man gpg

Now, where exactly do you gain security over using a symetric-key system?
You're really just forcing the user to save the passphrase and private key...
Just encrypt the file with AES/Twofish/IDEA/3DES/ad/nauseum, and tell the
user the passphrase.

Furthermore, all the encrypted storage in the world isn't going to do you much
good when you're transmitting stuff in cleartext. Someone is going to fire up
dsniff/snort/whatever and get all the goods without ever bothering to break
into your box.

I don't know what problem you're trying to solve, so I won't suggest an
alternative course of action, but if you'd like to send your problem to the
list, I (and probably others) would be happy to suggest alternatives.

Do you actually have data in two diferent formats in the same XML file, or can
you just change xml_parser_create to UTF-8 and be done with it? Does the XML
standard even allow multiple encodings???

Do it the other way, allow only characters
you know are safe and strip the rest. Use, for
example, a preg_replace pattern with negated
character range. Put all the allowed characters
into this range and '' as replace text.

$query = preg_replace('{[^' . preg_quote(ALLOWED_CHARS) . ']}', '', $query);

, where ALLOWED_CHARS is a constant containing...
allowed characters :8].

Why do you need to remove them? So I can't type <grin>? Is that a
security violation? All you need to do is use htmlentities() and/or
addslashes() to protect data being displayed or entered into a database.

If you're worried about HTML code being entered (guess from desire to strip
<, > and /) and messing up your site's layout, you might wanna call
strip_tags($String, $AllowedTags); where $AllowedTags is a string like
'<b><u><i>' if you want to allow bold, underline and italics.

What is your intention?

Well, I really don't know how much clearer the sentence that says "The optional offset parameter allows you to specify which character in haystack to start searching" can be -- if you can suggest some better wording, that would have worked for you, then maybe one of us can add a user note to the manual and/or a documentation bug requesting an enhancement. And, notwithstanding the clarity of the description, I agree it would be useful to have another example showing the use of the 3rd argument, so that could be done in the same way.

What is the best way to detach and run a command line based php script
in the background from a web-based php script, without the need for
reporting?

I have a web-based php script that gathers information and then passes
it off to several functions, which execute several other php scripts.
The problem is that the main php script does not return until all the
processes have signaled and is taking about 30 sec to complete. There
is no need for the child processes spawned by the main php script to
signal. I would like to spawn and detach them to finish in the
background; thus, dramatically reducing the load time of the main php
script.

It has been suggested to me to use the & with the shell_exec function,
but this still requires the child processes to signal.

Another suggestion was to use the pcntl_fork function, but my reading
suggest that this is not to be used with web-based applications and does
not compile in with mod_php (only the binary version). If I were to use
the binary version would I even be able to detach the forked child
processes? Doesn't pcntl_fork still require the child processes to
signal to the parent before exiting otherwise becoming zombie processes?

Any suggestions on the best way to handle this?

Respectfully,

Gary

Most of these speed increases can't be noticed in a small script, where
the end is within a few lines, but echo() really works well in larger
scripts where the end is far away.

In addition, print() only sort of works well in the "near" case and
doesn't work at all in the "far" case (as demonstrated when trying to
throw something printed, such as a book).

Finally, echo()ed statements always remain in the proper order, but
throwing a bunch of print()s will just get you a big mess on the floor
requiring an intelligent sort() to clean up -- and you know how tough it
can be to write a quick sort() algorithm!

The most obvious difference is "/Sites" vs. "/sites". If your PHP
server is using a case-sensitive filesystem, I'd check the whole
uppercase-lowercase thing first.

If you really wanted to be secure, you might implement some javascript

    If you want customizable layout without changing the logic, try the MVC
approach (model-view-control).
    The best way to do it is to create the data from php in a XML (generate
the logic), then create the layout with XSL. Thus, if you want to change the
layout, all you have to do is to change the XSL. Aso, if you change the
logic, you'll vave to change just the php generating the XML.
    Right now I'm doing just that, and I think this is the best approach
(for me at least).
    There are several platforms that already have this MVC approach

    Take a look at: http://www.interakt.ro/products/Krysalis/

Use an external database abstraction library. Like PEAR::DB -- however
good database design will help a lot in this regard.

I'm trying to find a way to search text files in a directory using php. I've
done some researching under the filesystem section on php.net but seem to
have come up empty handed. Is there a way to do keyword searches on a txt
file in a directory hopefully with some type of relevance ranking?

Thanks

This approach is rather simplistic, but may point you in the right
direction.

Open each file in the directory and count the number of times each key
word appears.
Return a list of links ranked by the number of times each key word
appears in each text file.

Just a starting point...HTH
