here is a set of functions that allow you to mimick a .htaccess style of
protected area I use them occasionally when I need quick and dirty protection
(i.e. single user, no specified permissions, etc)

it's not so much a tutorial as a basic example of simple protection
- maybe it gives you some ideas/insight.

------------------------------------------------------------------------

you use them like so:

<?php

// sessions are required for this to work
session_start();

// a line like this should be in you global include file
setSimplePageProtectionDetails("YOUR_USER_NAME", "YOUR_PWD");

// then on any page that needs protection (can also be set in the same global include)
simplePageProtection("YOUR_REALM");

here are the actual funcs:

<?php

function isCLI()
{
return (strtolower(php_sapi_name()) === 'cli');
}

function setSimplePageProtectionDetails($login, $pwd)
{

     if (!defined('SIMPLE_MICROSITE_AUTH_PW') && !defined('SIMPLE_MICROSITE_AUTH_USER')) {
         if (!$login || !$pwd) {
             return 0;
         }

         define('SIMPLE_MICROSITE_AUTH_USER', $login);
         define('SIMPLE_MICROSITE_AUTH_PW', $pwd);
     }

return -1;
}

function simplePageProtection($bla = null)
{
     if (isCLI()) {
         return; // no point 'protecting' the CLI
     }

     if (!defined('SIMPLE_MICROSITE_AUTH_PW') || !defined('SIMPLE_MICROSITE_AUTH_USER')) {
          die ('auth mechanism not setup properly');
     }

     if (($bla === null) || !$bla = strval($bla)) {
         $bla = 'micrositedefault';
     }

if (!isset($_SESSION['access_to_'.$bla.'_granted']) || !$_SESSION['access_to_'.$bla.'_granted']) {
$_SESSION['access_to_'.$bla.'_granted'] = false;

$login = isset($_SERVER[ 'PHP_AUTH_USER' ]) ? $_SERVER[ 'PHP_AUTH_USER' ]: false;
$pass = isset($_SERVER[ 'PHP_AUTH_PW' ]) ? $_SERVER[ 'PHP_AUTH_PW' ]: false;

         if (strtolower(trim($login)) == strtolower(trim(SIMPLE_MICROSITE_AUTH_USER)) && $pass ===
SIMPLE_MICROSITE_AUTH_PW) {
             $_SESSION['access_to_'.$bla.'_granted'] = true;
         } else {
             header('WWW-Authenticate: Basic realm="Please login '.SIMPLE_MICROSITE_AUTH_USER.'."');
             header('HTTP/1.0 401 Unauthorized');
             exit;

is there a easy way of converting an xml REST result to an object
returned by a SOAP call?

I know I can simply parse the REST and put it in a hash, curious if
there's a method of doing this.

simplexml_load_string() seems to give me simplexml objects inside my
multi-level hash, which isn't really what I want.

WILD GUESS!!!

Whatever class objects you had defined before you serialized the data,
are not defined when you unserialize the data.

You need to load all your class files in both serialize and
unserialize scripts -- The class definition is not stored in
serialized data, just the class 'data'

A DIFFERENT WILD GUESS!!! :-)

I don't think thats the problem - rather I get the impression that
there are references (and or resources) inside these SimpleXML objects
(e.g. the owning 'document') that cannot be serialized. I would suggest
caching the xml string and read that from disk (or where ever your storing
stuff) and creating an object from that whenever you need it. I don't believe that
you gain much from serializing an object (as compared to creating a new object) -
when you unserialize you have pretty much the same overhead as when creating an object
(I may be very wrong on this! - I do know that cloning an object is _much_ faster than
creating one for instance).

Stateless applications, ain't they fun?

I did a little experiment before Ajax cam into vogue with a small PHP
script that essentially ran a while loop with some sleep cycles built
in. This was placed in an iframe and another page was placed in another
iframe with javascript to update the second iframe if data had changed
in the first iframe based on a query running while PHP cycled the loop.
OB functions were used and it worked.

Clear?

So that experiment lead to a meta-refresh of the page in the first
iframe which then ran some PHP code that output some JavaScript to
update the second iframe. It worked better, but had its moments.

The point was to make the user experience better, a manager could see
that certain things were happening without having to refresh a page
manually. Also, a smaller more efficient query could be run and if the
data had not changed the system would not have to endure the overhead of
the larger query.

The end result? A stateless application with simulated state....much
like what Ajax does today. Really, it was as Ajax as could be, just not
using the httpRequest doohickey, or whatever it is.

There is a wide gulf between stateless applications and applications
with state. Even Java uses a hacked stateless connection (by having
something run client-side sending info a to listener on the
server...what does that sound like?). Isn't the intent for client server
apps to be stateless? Applications with state typically share memory
resources.

Building it yourself can be lots of fun and I have done this using
stream_select, fork, and other PCNTL and IPC functions. If you like
Pear, you can check out the Net Server package there. They have models
to do the forking for you for each client connection:

http://pear.php.net/package/Net_Server

Although I didn't use Net Server, I did review the code to get ideas on
how I'd like to build my server. It is useful.

Without caring what style you prefer, the correct reply to this request
is the following:

You seek a Code Beautifier for PHP.

I have found that only some IDE/Editor software contains such a beast.
The convention for most software code editing tools is to have Shift +
Ctrl + F do code formatting. I use PHP Eclipse to handle all my code
formatting. It will allow you to choose your preference for braces up
or down etc.

However...you may need to make a policy in your company. If you use
source control for your software, it may see changes in formatting as a
distinct major revision. Therefore, if you save code in "your" style
and another developer opens the file and resaves in "his style", then
you'll unnecessarily make version control a nightmare. Despite personal
preference, you MUST adhere to the style of the project. If you are the
sole developer, you define that style. If you are a coding monkey, then
you may have to suffer with the style that the architect before you
declared.

I can't work unless the code is formatted to my liking. I'm the OCD
type of programmer. Luckily I'm also in control of coding standards
within my company, whew! Get PHP Eclipse and do a general search for
PHP Code Beautifier then download some you like and try them out.

Beautiful code often contains fewer bugs.

I think no matter which style one uses, the following statement is
correct:

The closing brace goes directly under the first character of the line
containing the opening brace.

THE REST OF THIS IS *WAY* OFF-TOPIC

Though, in Lisp, I would actually "collapse" closing parens on a
single line, and considered the closing parens "isomorphic" even
though the actual one closing any given paren would not be directly
under the opening line:

(let* ((x (+ xoffset 3))
       (y (+ yoffset 4))
      )
  (do* ((x1 x (+ x 1))
        (y1 y (+ y 1))
    (while ...
      (for ...
        ;;; body here
) ) ) ) ;;; just close all the damn things on one line...

4 lines in a row with one ')' each was just too much for me to deal
with...

I don't do that in PHP, but you don't generally have, like, 5 closing
braces in a row in PHP either.

I believe I was quite clear when I suggested that the IDE should *NOT*
alter the actual code -- it should simply *DISPLAY* the style I
prefer.

For that matter, any new code I type should, by definition, be saved
in the style the rest of the file is in, no matter which style is
being displayed at the moment.

I don't think there are any IDEs on the market that do this.

They all seem to think they know how to align things better than I do,
and generally just screw it up, and, yes, make version control a
nightmare if you actually try to use their silly auto-format.

Hi,

Some months ago I was looking for some code for "loading" dynamic xml
data structures my php scripts. I didn't found anything simple and
flexible for my needs.

I found handy the PEAR XML_beautifier tokenizer, and then I write a
simple function to extract all the data with the right array structure
as needed for my project. A recursive function to extract tag elements
data from the tokenized arrays (attached below)

Have a look at the code below. In some lines I process part of the
contents from your xml sample file, so you can have something to get
started, it you find handy my approach.

I've attached a partial output from the data extracted by this code too.

To run the code you need PEAR and XML_Beautifier and dependencies (if
any, now don't remember if XML_parser is in the PEAR base install or not).

Have fun, :-)

thanx all for the reply.
Yes, i am new to PHP
I am a c++ programmer and now i am trying to learn php.

i guess i did not explain the problem correct.

the code is generating an textbox for each record.

while(query )//here the query is opened
{
 <table ">
 <tr>
 <td ><?php query->name ?> </td> // record from database
 <td > Please fill in your age:</td> //text
 <td "><input name="age" type="text" </td> //textbox,
 <td ><a href="<? echo
"otherform.php?age=PLACE_HERE_THE_VALUE_FROM_QUANTITY_TEXTBOX&name=query->name";
?> "</td>
 </tr>
 </table>
}

how can i get the value from the textbox? i don't have form tag
if i have 50 records, there are 50 textboxes named "age" right?

thanx all for the reply.
Yes, i am new to PHP
I am a c++ programmer and now i am trying to learn php.

i guess i did not explain the problem correct.

the code is generating an textbox for each record.

how can i get the value from the textbox? i don't have form tag
if i have 50 records, there are 50 textboxes named "age" right?

I am using this to compare todays date with dates retieved from a database.
The problem is it seem to retrun the same value for the $then variable

and can be seen ot working here....

http://nationalservicesscotland.com/cms/time.php

session_start();
include ('../shared/connect.php');

$query= "SELECT headline, id, expiry, link FROM events";

$result= mysql_query($query);

while ($row = mysql_fetch_array($result, MYSQL_ASSOC)){

$compare= explode("/", $row['expiry']);

$day = isset($compare[0]) ? $compare[0] : null;
echo "day is $day br> ";
$month = isset($compare[1]) ? $compare[1] : null;
echo "month is $month br> ";
$year = isset($compare[2]) ? $compare[2] : null;
echo "year is $year br> ";

$then = mktime(0,0,0,$month,$day, $year);

$now = mktime (0,0,0,date("m"),date("d"),date("Y"));

$diff = $now - $then;

echo "today is $today ";
echo "expiry date is $ross ";
echo "now mktime value is is $now ";
echo "then mkvalue is $then ";
if ($diff < 0 ) {
/*$text = stripslashes ($row['headline']);
 $newtext = wordwrap($text, 12, "\n", 1);
 $link=$row['link'];
 echo $newtext."<a href=\"$link\">...read more</a>"." ";*/

}
}
?>
