I'm having some problems with the DB::isError function identifying a
non-object as an error object (or so it seems). I'm using postgreSQL
7.3.x. The relevant code is below:

/*******************[ my code start ]***********************/

   $sql_queries = array();

    $sql_queries[0] = 'BEGIN';
    $sql_queries[1] = "INSERT INTO domain (name,table_name)
VALUES('$domainname','$tablename')";
    $sql_queries[2] = 'CREATE TABLE ' . $tablename . '_account ()
INHERITS (domain_account_template)';
    $sql_queries[3] = 'CREATE TABLE ' . $tablename . '_alias () INHERITS
(domain_alias_template)';
    $sql_queries[4] = 'CREATE TABLE ' . $tablename . '_option ()
INHERITS (domain_account_template)';
    $sql_queries[5] = 'END';

    // go though and execute all the queries (it fails on the
    // first one
    foreach($sql_queries as $query)
    {
      // show me which query is executing
      echo $query . "<br/>";
      $result = $db->query($query);

      // this tells me that $result is an integer == 1 and
      // so is DB_OK, which I believe the code above is returning
      echo getType($result) . ": " . $result . ": " . DB_OK . "<br/>";

      //this test tells me that it is NOT an object
      if(is_object($result)) { echo "its an object."; }
      else {echo "its NOT an object"; }

      //this always ends up as true, because it executes the code
      //in this block
      if(DB::isError($result));
      {
        //at this point, I get a fatal error saying that I'm
        //attempting to call a member function on a non-object
        $error = $result->getMessage() . $result->getDebugInfo();
        $db->query('ABORT');
        die($error);
      }
    }

/********************[ my code end ]***********************/

now, when I looked at the DB::isError code, it looked like so:

    /**
     * Tell whether a result code from a DB method is an error
     *
     * param int $value result code
     *
     * return bool whether $value is an error
     *
     * access public
     */
    function isError($value)
    {
        return (is_object($value) &&
                (get_class($value) == 'db_error' ||
                 is_subclass_of($value, 'db_error')));
    }

So, it seems, that although I've already found (in my code) that the
variable in question is NOT an object, isError STILL finds that it is
not only an object, but is an object of class db_error!

I'm really confused. Clearly I'm missing something here. Does anyone
have any pointers for me?

Ray,

I can create the XML of the document that I want to generate using the built
in XML functions in PHP.

THe thing I then want to do is be able to do is then use that XML to create
documents in multiple formats, e.g. PDF.

I think that I can use DocBook or Apache FO to do this, but I am not sure
which one to use or how to go about doing it.

Basically I want to be abel to speciy an output format and run the XML
through a transformation to get that format.

Does that make any more sense?

Hi Russell,

If you're documenting PHP software, you might consider using
phpDocumentor. Your manual would be in DocBook, and phpDocumentor would
both transform to HTML/PDF/CHM, and link to the auto-parsed API docs
straight from the source. Kind of handy for people who'd rather code
than figure out where things have changed :)

What do u mean the manual would be in Docbook, how do i get it in docbook ?
I would like to fill the generated docs with more info than is already
there, including diagrams, flow charts , object framework diagrams. I also
have trouble with the headers of my scripts, here is an example of one

/**
* author Dan Rossi <email>
* version $Id: index.php,v 1.00 2003/05/21
* Shotlist Data Entry Interface
* This script handles the data entry of new shotlist tapes
* it also handles the editing and updating of current shotlist entries.
*/

Althought the description will only get parsed if there is an include above
and the header gets generated with the include statement, how can i fix
this ?

Depends on your environment. I usually have mine set up as rw-rw----
(directories as rwxrwx---) with the owner the same as what my webserver
runs as (apache), and group writable so that multiple people can edit
them. Even if you're the only one who is going to edit the files, and
you're the owner of the files and you're set up rw-r--r--, you may run
into problems if php/Apache needs to write to the file (unless Apache is
running as you).

Well, I want to have the most security for my .php file because it stores
passwords. Besides if there is no permissions set for the 'world' how can
someone's browser use the .php file? shouldn't it atleast have a read or
execute (I'm not sure, please comment on this) persmission?

attached mail follows:

rw-r-r should do it. Permissions really only become an issue using Perl. PHP is very accomodating that way.

No, it's the webserver which is serving up the file; the client doesn't
come into play for permissions. Technically, the file only needs to be
r-------- with the owner of the file as same as the what the web server
is running as. However, you won't be able to write to it (unless you're
root). My suggestion would be, if you're going to be the only one
editing the file....

1) Make the owner of the file you
2) Make the group of the file the same as your webserver
3) Set the permissions to 640 (rw-r-----)
4) Place it in a directory outside of the webserver's document root
5) Make yourself the owner of the directory, and group the same as the
webserver.
6) Set permissions on the directory as 750 (rwxr-x---)

You're tired so you want others to do your work?

Maintain a 'flag' which stores 'previous' value of $mydata-district. If 'flag'
and $mydata-district differ print $mydata-district and update 'flag'.

I cannot declare $temp = $mydata->district; outside while ($mydata so ... ?
I'm missing something in my logic. That's why I asked.
It wouldn't make sense to declare this twice:
while ($mydata = mysql_fetch_object($myquery))

$temp = "";
echo "<table>\n";
while ($mydata = mysql_fetch_object($myquery))
{
$temp = $mydata->district;
while ($temp <> $mydata->region)
{
echo "<tr bgcolor=\"#CCCCCC\"><td>$mydata->district</td></tr>\n";
}
echo "<tr bgcolor=\"#CCCCCC\"><td>$mydata->city</td>
<td>$mydata->place</td>
<td>$mydata->meetingtime</td></tr>\n";
}
echo "</table>\n";

attached mail follows:

Just my two cents :)

$temp = "";
echo "<table>\n";
while ($mydata = mysql_fetch_object($myquery)) {
     if ($temp != $mydata->district) {
         $temp = $mydata->district;
         echo "<tr bgcolor=\"#CCCCCC\"><td>$mydata->district</td></tr>\n";
     }
     echo "<tr bgcolor=\"#CCCCCC\"><td>$mydata->city</td>
     <td>$mydata->place</td>
     <td>$mydata->meetingtime</td></tr>\n";
}
echo "</table>\n";

Hope it helps.

You could set the flag to null outside the loop, then check at the top
of your loop to see if the flag and district differ. If so set the
flag, echo what you need, and move on. The first time the loop runs the
flag will differ and you will set it to the first vale of district as
well as echo your district header, afterwords things will continue as
expected. If you do not want to print out the district info the first
time the loop runs then you can set $mydata outside the loop, initialize
the flag variable, then use a do..while[1] loop to process the rest of
your data.

You may want to try this class for composing and sending e-mail messages.

It comes with sub-classes specialized in deliverying messages with
sendmail or compatible, qmail and SMTP. If you do not want to use the
class directly, it comes with wrapper functions that emulate the mail()
function.

http://www.phpclasses.org/mimemessage

For SMTP delivery, you also need this:

I agree on that. It is funny that you often find people spliting hairs on
optimizing code like "but templates are slow" or even to the extreme "should
I use single or double quotes for strings?", while things like this affect
user expirience much, much more.

=======================================
This message is for the benefit of new subscribers
and those new to PHP. Please feel free to add
more points and send to the list.
=======================================
1. If you have any queries/problems about PHP try
http://www.php.net/manual/en first. You can
download a copy and use it offline also.

Please also try http://www.php.net/manual/faq.php
for answers to frequently answered questions
about PHP (added by Christophe Chisogne).

2. Try http://www.google.com next. Searching for
"php YOUR QUERY" may fetch you relevant
information within the first 10 results.

3. There is a searchable archive of the mailing
list discussion at
http://phparch.com/mailinglists. Many of the
common topics are discussed repeatedly, and you
may get answer to your query from the earlier
discussions.

For example: One of the repeatedly discussed
question in the list is "Best PHP editor".
Everyone has his/her favourite editor.
You can get all the opinions by going through the
list archives. If you want a chosen list try this
link : http://phpeditors.linuxbackup.co.uk/
(contributed by Christophe Chisogne).

4. Not sure if PHP is working or you want find out
what extensions are available to you?

Just put the following code into a file with a
.php extension and access it through your
webserver:

<?php
phpinfo();
?>

If PHP is installed you will see a page with a lot
of information on it. If PHP is not installed (or
not working correctly) your browser will try
to download the file.

(contributed by Teren and reworded by Chris W
Parker)

5. If you are stuck with a script and do not
understand what is wrong, instead
of posting the whole script, try doing some
research yourself. One useful trick is to print
the variable/sql query using print or echo
command and check whether you get what you
expected.

After diagnosing the problem, send the details of
your efforts (following steps 1, 2 & 3) and ask
for help.

6. PHP is a server side scripting language.
Whatever processing PHP does takes
place BEFORE the output reaches the client.
Therefore, it is not possible to access
users' computer related information (OS, screen
size etc) using PHP. Nor can you modify any the
user side settings. You need to go for
JavaScript and ask the question in a JavaScript
list.

On the other hand, you can access the information
that is SENT by the user's browser when a client
requests a page from your server. You can
find details about browser, OS etc as reported by
this request. - contributed by Wouter van Vliet
and reworded by Chris W Parker.

7. Provide a clear descriptive subject line. Avoid
general subjects like "Help!!", "A Question" etc.
Especially avoid blank subjects.

8. When you want to start a new topic, open a new
mail composer and enter the mailing list address
php-generallists.php.net instead of replying to
an existing thread and replacing the subject and
body with your message.

9. It's always a good idea to post back to the
list once you've solved your problem. People
usually add [SOLVED] to the subject line of their
email when posting solutions. By posting your
solution you're helping the next person with the
same question. [contribued by Chris W Parker]

10. Ask smart questions

Hi Folks:

I just released version 1.6.0RC4 of PEAR DB. Several things have been
fixed since RC1 which is included with the latest PHP RC release. Also,
if you're using 1.5.0 variants or earlier, definitely check out the new
version for loads of enhancements and way fewer bugs.

I've also spent a bunch of time documenting the new functionality and
fixing the old docs. Most of the changes are already viewable on the PEAR
website and most of the remaining improvements should be in place when the
docs get rebuilt Sunday around 12pm UTC.

So, please download the package and test it out as well as read the
documentation. Please file bug reports if stuff doesn't work or is
unclear.

Download: http://pear.php.net/get/DB-1.6.0RC4.tgz

I have a JavaScript style sheet switcher that works quite nicely, but I
want to make a MULTI-style switcher; one that lets you switch various
items independently of one another.

It sounds like it can be done with either PHP or JavaScript, each with
its own advantages. The biggest disadvantage with PHP is that switching
styles reloads teh page.

Does anyone know if there's a PHP method that does NOT involve reloading
the page?

Here are a couple key articles I've checked out:

I'm not sure that helps too much. Subtracting unix timestamps will give
the difference in seconds. You can then use division and remainders to
calculate the hours, minutes and seconds.

The problem here is your approach. PHP can only be used to control the
content sent to browsers. Once the browser receives the content PHP is
out of the picture until the next reload. You have to use javascript or
some other client side language to change anything on a page once it is
loaded in the browser. The referred to post describes this in detail.

Hi everyone - hope there's someone good at PDFlib out there…

I'm trying to use a picture, a TIFF image, with transparency, in a PDF
created by a PHP-script...

The manual says that only "explicit transparency" can be used when
working with TIFF images, and that this operation requires two steps…
But then the manual loses me, and I don't understand what the "two
steps" that seems to be required actually meens…

Isn't it sufficiant to have a TIFF image with transparency, or do I
have to have some kind of second image and use that as some kind of
mask to acquire transparency effects? Will this, if so, require two
image files per image instead as one?

Hope this is not OT, if so, i apologize…

$_SESSION['language']="us";

else if ($_POST['langue']=="fr")

$_SESSION['language']="fr";

header("Location: http://".$_SERVER['HTTP_HOST'].$_POST['page_name']);

/*********************************************/

When the header function is called I'm correctly redirected on the right

Can you please help me resolving this problem. I've tried directly entering

header("Location: index.php");

but it's the same problem.

Try session_write_close() before you redirect.

If you rely on URL rewriting to transmit your session ID, this won't work for header redirects, so you need to manually include the SID value. In any case, this is good defensive programming (in case that configuration parameter ever gets changed!). So your redirect should look like:

header("Location: http://".$_SERVER['HTTP_HOST'].$_POST['page_name'].'?'.SID);

Cheers!

Nothing wrong with the above, it's perfectly valid -- just a slightly

Inside of a class I am trying to make a call to a function in another class.

I have one class defined to be my DataBase Interface call "dbi". To use
that class I do this:

$db = new dbi;

Then I can use the functions in "dbi" like this:

$db->dbquery("select * from whatever");

Inside another class (Class2) I have several functions that need database
access. So in each function I can use "$db = new dbi;" and then use the
functions as usual ($db->dbquery("blah");).

I am wondering, can I create the new "dbi" instance at the top of Class2 and
have all the functions within Class2 use the "dbi" class reference variable
($db)?

If so, would the use be something like this:

$this->db->dbquery("blah");

Hi all,

I am using PHP v4.12, and here is the scenario.

I have one page, index.php with a form that has a searchfield (dropdown) and
searchcriteria (textbox). When submitted I want to populate two session
variables with the form values of searchfield and searchcriteria. This page
also uses paging, and whenever I click next, my session variables seem to
die. I have globals turned on.

So basically, we the page initially loads I display all the results from a
db query. Paging works fine. If someone submits the form, I want to
populate two session variables and build a new sql statment based on the
user input. Clickling "next" or "previous" should retain the same search
results until the user submits the form again or those session variables
expire.

Help please.

Which OS are you on? I seem to remember that a bug in 4.1.2 meant that sessions were "write only" on one particular group of OS -- but I can no longer remember whether it was *n*x or Windoze. (Or was that in PHP 4.2.1? -- like I said, it was the dim-and-distant past! ;) A search in the archives might tell you, but as 4.1.2 is now well out of date why not just upgrade?

Hi, my company's looking to buy a PHP encoder to secure the source code.
The encoded scripts should be able to run on Solaris platform (Apache webserver), and should only require minimum changes to the server.

I looked on Zend Encoder and was ready to suggest it when I realise that the US$ 960 tag is only for a year's license. And I don't think we have the budget to buy the perpetual license.

Could anyone recommend other PHP encoder for us?
