What is your code in the included db.html? You do realise that unless
you've told the server especially that it won't know to parse your HTML
files for PHP code as well. HTML is embedded in PHP, not the other way
around. If you think more like that, you'll realise why it's not
working.

in the db.html is the follow code:

try {
$db = new PDO(mysql:host={$host};dbname={$database}, $user, $pass);
}catch(PDOException $pe)
{ die('Connection error, because: ' .$pe-getMessage());

Yes my Webserver parse html files as php. My formular work without problems,

All was good, only that not want write in database. Okay thanks all, and im sorry that i disturb with the easy questions. All mistakes in the script i has found with google and the manual, but when not give message, there is problem. Often i not know the correct word which should use to search. For example i have a HTML Table, in this are much Code for calculate the Stock Portfolio. Value, Dividend, Win, Lose Thats okay, but i search a function with can tell php that should calculate all data in table. At moment i have write much Variables for every stock which is in Portfolio. Better were that i can copy the mathematical formula from one row/cell in next row/cell, like in excel. That i not found, because i not know what is the right words for searching.

[PHP] Wierd cookie behaviour
Hi All,
I'm scratching my head a bit here. I have a form handling script that
branches dependent on whether a user has admin privileges over the
application. Here's the function that tests this:
function isAdmin($user){
global $chan;
$query = SELECT isadmin FROM csw_user WHERE username = ' .
mysql_real_escape_string($user) . ';
// echo p$query/p\n;
$result_table = mysql_query ($query, $chan) or die (Error: Can't retrieve
the data);
if ($result_row = mysql_fetch_array ($result_table)){
$canAdminister = $result_row['isadmin'] 0;
} else {
$canAdminister = FALSE;
}
return ($canAdminister);
}
Note the commented echoing of the query, which I uncommented during
debugging.
This function was failing with the message from die() Error: Can't
retrieve the data. On uncommenting the echo statement, I got:
SELECT isadmin FROM csw_user WHERE username = ''
IOW, there was a blank string passed to the isAdmin function.
So I checked at a higher level and temporarily modified the code to
read:
echo pre;
print_r ($_COOKIE);
echo /pre\n;
$canAdministrate = isAdmin($_COOKIE['username']);
This showed that $_COOKIE['username'] contained the username of the
logged-on user as I expected, yet that username was not passed to the
isAdmin function 8-/
FWIW, I've resolved the issue in that it no longer happens. I'd
forgotten to put the opening and closing html, head, and body tags and
the issue went away as soon as I did that. However, I'd appreciate
info on why as I need to run some scripts within a validated user
session where those scripts do their processing and then use the
header function to redirect the browser to an appropriate page.
TIA,

Re: [PHP] Error recovery - fatal errors
You can register a shutdown function that gets called even in the case of a
fatal error. We use something like this:
public function init() {
register_shutdown_function(array('Bootstrap', 'fatalErrorCatcher'));
...
}
public function fatalErrorCatcher() {
$error = error_get_last();
if( $error (
$error['type'] === E_ERROR ||
$error['type'] === E_COMPILE_ERROR ||
$error['type'] === E_CORE_ERROR ||
$error['type'] === E_PARSE
)) {
// kill the buffer content, it's broken anyway
while(ob_get_level()) {
ob_end_clean();
}
// log error to a file
...
// issue 500 and dump out a static site is broken oh noes!
page
header('HTTP/1.1 500 Internal Server Error');
echo file_get_contents('fail-whale.html');
}
}
In catchFatalError() we check the last error to see if it's truly fatal. Our
general error-handler has already handled all other error types, and this
since function gets called no matter how the PHP process shutsdown, you
don't want to issue a 500 for a successful request. :)

I recently had a case where $dbh was NULL, which triggers a fatal error from SQLite. In principle such a bug should show up quickly, but this one had lain untriggered for about a year. It seems to me somewhat arbitrary for this to be designated a fatal error. Is there a way I can catch these? Most SQLite error situations I'm solving with try/catch but no luck with this one so far. You've got something wrong: either $dbh is not null or the error is not from sqlite. I'm guessing the former. To avoid situations like that, do proper error checking (i.e. actually check that your database connection was opened succesfully). No, $dbh was unitialised. It was a coding error where I was using $dbhs instead of $dbh. Since what I was apparently trying to do last year was wrong anyway I've rejigged that section. And obviously I do check that the db is opened; just that in this instance I was using the wrong variable. Error handling in library packages seems somewhat arbitrary - e.g. opendir may give an E_WARNING, but closedir, readdir don't. You can avoid all problems with error output by turning off error displays in php.ini (set display_errors = off) - use error logging instead. That's the recommended setting for production servers. This is not a browser/webserver situation in the classic manner. In this case, the browser, PHP code, and the instance of apache used are all running on the user's machine. The user just thinks they are running a local application. Cheers -- tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Consistent Class Renaming (Simple Refactoring)
Hi there,
i have following problem:
Assume we have a cron.php which is called every hour by a cron job.
This cron.php should then be used to execute other php-scripts
script1.php, script2.php.
For a pitty our server has Safe-Mode activated so we arent able to
shell_exec / exec those files. So we came up with the idea: Lets include
those scripts using include(). But this lead us to another problem:
Namespace conflicts (our server is running php 2.7.2) especially with
classes and constants.
Example:
script1.php
?php
class A {
public function test(){ echo im class A at script 1; }
}
?
script2.php
?php
class A {
public function test(){ echo im class A at script 2; }
}
?
cron.php
?php
include('./script1.php');
include('./script2.php');
?
Cron.php will raise a cannot redefine class A error.
So my idea is to continously rename every occurence of class names and
constants in the scripts by adding a suffix (ie. class A_123 and class
A_234). Do you have an idea how to implement this during the deployment
step?
Sincerly yours

The only way I could think of would be to use namespaces, but that
would involve some reworking.

Pretty sure you're *not* running PHP 2.7.2. If you are, give up now.
Example:
script1.php
?php
class A {

}

Cron.php will raise a cannot redefine class A error.
Well of course, you would get that error. But I'm completely lost beyond
that point. Why must both scripts use the same class names in them? Why
not call the class in script2.php B instead of A? I'm guessing you
left out a huge piece of explanation here.
So my idea is to continously rename every occurence of class names
and constants in the scripts by adding a suffix (ie. class A_123 and
class A_234). Do you have an idea how to implement this during the
deployment step?
