Hey everyone, I just delved into
classes recently and have been having
moderate success so far.
I have a puzzler though.
I have the following class decalred and instantiated:
class Notify {
var $q = array();
public function addtoQ($string, $class)
{
$message = 'span class='. $class .''.
$string .'/span';
$this-q[] = $message;
}
public function printQ()
{
if (isset($q))
{
echo 'p align=center
class=notification';
foreach($this-q as $msg)
{
echo $msg .\n;
}
echo '/p';
}
return;
}
function __destruct()
{
if (isset($q))
{
unset($this-q);
}
}
} // END CLASS Notify
And in my script, I call it like so:
$Notif = new Notify;
I have run other statements in other classes that should be
adding to the $q
array (ie. Notify::addtoQ('ERROR! There Was An Error
Updating The
Database!', 'error');)
However, when I try to get my webpage to display them
using:
$Notify-printQ();
it does not seem to want to loop through this array (and
print the
messages). I am getting NO error message, in fact
everything 'looks' fine,
I'm just not seeing the appropriate message.
Any help would be appreicated!
Allen,
You have made a small typing mistake in function printQ() where you would like
to checked the array for its existence. By mistake you have wrote if
(isset($q)). But your array variable is not an freely accessible array,the
array is embedded into an object. So, you have to write the like if
(isset($this-q)).
Another point, you can't add a message into the array by calling the member
function addtoQ() using scope resolution operator ::. If you really want to
add message into the array, you have to call the member function from within
the object. (ie. $Notif-addtoQ('ERROR! There Was An Error Updating The
Database!', 'error');).

Fwd: [PHP] Re: ErrorException and set_exception_handler()
-- Forwarded message -- From: Randall Girard randallgir...@hotmail.com Date: 2009/12/14 Subject: RE: [PHP] Re: ErrorException and set_exception_handler() To: rquadl...@googlemail.com I understood exactly what was going on in the code! (I'm no fool when it comes to this) I just thought (logically) that if the ERROR_HANDLER forces you to end the script when necessary, that the EXCEPTION_HANDLER would have a similar function... Rather, there is not a way at all to continue execution. Now that I contemplate this further, I think I prefer this anyway as I would NOT want errors firing for ANY reason on a production website! Additionally when one error happens it often triggers a number of errors (if execution continues) and when logging of course they are all logged. I would rather have just the one backtraced error log, and so forth. Thank you for your help however!

[PHP] Parsing JSON; back-slash problem
This seems like a pretty basic question, but it has me stumped.
Here's my scenario: I'm using Douglas Crockford's JSON2.js to parse an
object in JavaScript, which I then pass to a PHP script to store in a
file. I use JSON.stringify() on the object, which logs to the console
as this:
{employees:{data:{John:{fname:John,lname:Doe,city:Toronto,country:Canada
Then I use the jQuery POST function to send it to a PHP script. Before
doing anything with it in PHP, I log the received value to the
console, and this is what I get:
{\employees\:{\data\:{\John\:{\fname\:\John\,\lname\:\Doe\,\city\:\Toronto\,\country\:\Canada\
The problem is, when I call the script to retrieve this data from a
file, JSON.parse can't parse it because of the back-slashes. I'm
pretty sure my problem is on the PHP side (since it's fine coming out
of JS); what do I need to do to fix this? is a preg_replace enough?

[PHP] Debian Lenny: Which 5.3 package should I use?
Hi Guys Gals, I've been playing around with PHP 5.3 for a while now on development servers and servers solely used for start-ups and lower-profile apps. But now I'm about to upgrade the servers for a high profile/high traffic website and with this upgrade I'd also like to make the switch from 5.2 to 5.3. But - which package should I choose? I want to rely on community tested builds, so compiling myself is out of the question. The server will run on Debian Lenny. The Two and a Half options I've been able to find are: DotDeb: http://www.dotdeb.org/2009/12/06/the-php-5-3-1-packages-have-been-updated/ Debian Experimental: http://packages.debian.org/source/experimental/php5 ~raaa Launchpad: https://launchpad.net/~raaa/+archive/ppa Are there any others? Which is the best when it comes to: - Security? - Stability? - Ease of upgrade to Debian Squeeze later next year? Thanks in advance for any help you're able to offer!

I have to say, I do like MySQL, it's very flexible and fast, and being able to choose different storage engines for different tables in the same DB is brilliant! I really don't think there's anything to overly worry about from Oracle, as the two DB's have different audiences. Thanks, Ash http://www.ashleysheridan.co.uk Unfortunately, I do not share your optimism. I believe that Oracle taking over MySQL would be a disaster of epic proportions. The different audiences theory has been bought up several times but I haven't [to date] seen a sound justification for it. Oracle wants everyone to use ... Oracle, I can't see how this different audiences theory is going to make Oracle promote MySQL, perhaps someone can tell me? I don't think the EU would be able to do anything about it. The powerful companies almost always get what they want. I don't think Monty wouldn't be doing this unless he felt that something [put mildly] bad is coming. What has happened, has happened. Trying to figure out who is to blame for this mess is pointless. Ideally, It would be nice if Oracle took its claws off MySQL and found another project to ruin. Note: I am *not* trying to spread FUD I've always been led to believe that you go with MySQL if you want speed, Oracle if you want data integrity. I know they both handle each one admirably, but Oracle is known more for guarding the data against mishaps and MySQL is known more for performance. I just think it may be a little early to be condemning Oracle yet, we should wait a little to at least see what stance they have on the whole thing. And before you ask, no I have no connection to Oracle, I'm an avid MySQL fan! Thanks, Ash http://www.ashleysheridan.co.uk

Re: [PHP] strip tags but preserve title attributes
I've had quite some luck using the html2text class by Jon Abernathy http://www.chuggnutt.com/html2text.php It's targetted to php 4, and rather old code - but it does the job for me. Where the 'job for me' is converting html to text for when I'm sending out emails in HTML format and want to offer the proper plain text alternative. To be honest, I haven't checked how it handles title/alt attributes on images - but I'm confident that it does it nicely, and if it doesn't that you can add it yourself.

Re: [PHP] can't retrieve more than 1 record at the time still
2009/12/14 Catherine Madsen cmad...@berkeley.edu:
Hi Again,
Following the suggestions I received from a earlier post, I've closed the
statement
while ($stmt-fetch(PDO::FETCH_BOUND))
before $stmt = NULL;
I don't get an error anymore, but still retrieve only one record.
To check that the array was being filled correctly, I inserted in several
places $ncand = count($_SESSION['numberCand']);
$ndocid = count($_SESSION['DOCIDs']);
and the count is always 0 for $ndocid and 1 for $ncand.
Now I believe that the array is not being filled, and that's why only the
last record gets processed. Can anybody see what I'm doing wrong in the for
each statement? The updated code is below.
Thank you for your help.

Earlier message:
I'm really in need of help. I'm not a PHP programmer, but I've been given
the privilege of customizing a script written by somebody else and can't get
it to work right. I have to query 2 different tables in 2 different Oracle
10G DBs, one's mine (my_schema.my_table), the other (otherdb.other_table)
belongs to another department. In my_table, I have the doc_id and the
app_id for a record. In other_table there's the doc_id and pdf to
retrieve. The goal is to make a PDF file from each BLOB in other_table and
store them in the right directory under hash(app_id). PDO has been
installed and working, and I can connect to both DBs without a problem. If
my query limits the retrieval to one record, the script works, but if I try
to run it for all records, one pdf file is correctly created in the right
directory then I get the following error: PHP Fatal error: Call to a
member function fetch() on a non-object in /my_location/my_script.php on
line 154. It the while ($stmt-fetch(PDO::FETCH_BOUND)) line. I've
pasted my script below. I thought my problem was that maybe I was in the
wrong directory after creation of the first pdf, but several tries changing
the directory didn't make a difference. Right now, I'm running the script
at the command line. Soon I'm going to have a few hundred records to deal
with and cannot do it one by one! Any help would be very much appreciated.
Thank you!

Re: [PHP] Class not functioning
Hey all (and Nirmalya, thanks for the help!),
I have a question that I just can't seem to find via Google.
I want to be able to add messages to a qeue whenever my classes complete (or
fail to complete) specific functions. I think have a call within my html to
my Notifier class to print all qeued messages (via a function 'printQ').
How do I access a globally instantiated class from within another class?
Example:
?php
// INSTANTIATE
$Meetgreet = new Meetgreet;
$Notify = new Notifier;
...
...
$Meetgreet-deleteSingle($id, 1); // This completes a function within
Meetgreet class. That function needs to be able to use the Notifier function
addtoQ(), how would this be accomplished?
?

Hey everyone, I just delved into
classes recently and have been having
moderate success so far.
I have a puzzler though.
I have the following class decalred and instantiated:
class Notify {
var $q = array();
public function addtoQ($string, $class)
{
$message = 'span class='. $class .''.
$string .'/span';
$this-q[] = $message;
}
public function printQ()
{
if (isset($q))
{
echo 'p align=center

foreach($this-q as $msg)
{

}
echo '/p';
}
return;
}
function __destruct()
{
if (isset($q))
{
unset($this-q);
}
}
} // END CLASS Notify
And in my script, I call it like so:
$Notif = new Notify;
I have run other statements in other classes that should be
adding to the $q
array (ie. Notify::addtoQ('ERROR! There Was An Error
Updating The
Database!', 'error');)
However, when I try to get my webpage to display them
using:
$Notify-printQ();
it does not seem to want to loop through this array (and
print the
messages). I am getting NO error message, in fact
everything 'looks' fine,
I'm just not seeing the appropriate message.
Any help would be appreicated!
Allen,
You have made a small typing mistake in function printQ() where you would
like to checked the array for its existence. By mistake you have wrote if
(isset($q)). But your array variable is not an freely accessible array,the
array is embedded into an object. So, you have to write the like if
(isset($this-q)).
Another point, you can't add a message into the array by calling the
member function addtoQ() using scope resolution operator ::. If you really
want to add message into the array, you have to call the member function
from within the object. (ie. $Notif-addtoQ('ERROR! There Was An Error
Updating The Database!', 'error');).

public function deleteSingle($id, $number) {
// do something
global $Notify;
$Notify-addToQ( .. );
}
}
?
The long(er) answer:
I assume your Notifier object functions as singleton? Ie; accross your
entire application, there is only one instance of that class?
Why not go-static? That is, to my experience, the sweetest way to make
something globally accessible - without making something global. Like so
?php
class Notifier {
protected static $queue = Array();
// make sure it can't be instantiated
private constructer __construct() {
}
public static function addToQ( $arg, $anotherArg) {
self::$queue[] = $arg.' - '.$anotherArg;
}
}
// and then from within any method anywhere, call
Notifier::addToQ('foo', 'bar');
?
Does that work for you?

Re: [PHP] Class not functioning
Wouter,
Implementing your static idea was pretty easy, I was already referencing
Notifier with the :: operator in my other methods, however I am running into
trouble assigning new values to the static array.
I am getting a syntax error, unexpected '[' on this line of my Notifier
class:
Notifier::notifyQ[] = 'div class='.$message;
. . .
Any ideas why this is causing an error?
(note: I did try using $this-Notifier, and it said I cannot do what-not to
a non-object, can't remember the exact message at the moment)

2009/12/15 Allen McCabe allenmcc...@gmail.com
Hey all (and Nirmalya, thanks for the help!),
I have a question that I just can't seem to find via Google.
I want to be able to add messages to a qeue whenever my classes complete
(or
fail to complete) specific functions. I think have a call within my html
to
my Notifier class to print all qeued messages (via a function 'printQ').
How do I access a globally instantiated class from within another class?
Example:
?php
// INSTANTIATE
$Meetgreet = new Meetgreet;
$Notify = new Notifier;
...
...
$Meetgreet-deleteSingle($id, 1); // This completes a function within
Meetgreet class. That function needs to be able to use the Notifier
function
addtoQ(), how would this be accomplished?
?
...
...
?php $Notify-printQ() ?

Hey everyone, I just delved into
classes recently and have been having
moderate success so far.
I have a puzzler though.
I have the following class decalred and instantiated:
class Notify {
var $q = array();
public function addtoQ($string, $class)
{
$message = 'span class='. $class .''.
$string .'/span';
$this-q[] = $message;
}
public function printQ()
{
if (isset($q))
{
echo 'p align=center
class=notification';
foreach($this-q as $msg)
{
echo $msg .\n;
}
echo '/p';
}
return;
}
function __destruct()
{
if (isset($q))
{
unset($this-q);
}
}
} // END CLASS Notify
And in my script, I call it like so:
$Notif = new Notify;
I have run other statements in other classes that should be
adding to the $q
array (ie. Notify::addtoQ('ERROR! There Was An Error
Updating The
Database!', 'error');)
However, when I try to get my webpage to display them
using:
$Notify-printQ();
it does not seem to want to loop through this array (and
print the
messages). I am getting NO error message, in fact
everything 'looks' fine,
I'm just not seeing the appropriate message.
Any help would be appreicated!
Allen,
You have made a small typing mistake in function printQ() where you
would
like to checked the array for its existence. By mistake you have wrote
if
(isset($q)). But your array variable is not an freely accessible
array,the
array is embedded into an object. So, you have to write the like if
(isset($this-q)).
Another point, you can't add a message into the array by calling the
member function addtoQ() using scope resolution operator ::. If you
really
want to add message into the array, you have to call the member function
from within the object. (ie. $Notif-addtoQ('ERROR! There Was An Error
Updating The Database!', 'error');).

Re: [PHP] Class not functioning
Sorry, and then I didn't keep it on list :-(

Please reply to the list. Just google for php registry pattern. Here is a
very basic example. There are better OOP people here than I.
class Registry {
protected $_objects = array();
function set($name, $object) {
$this-_objects[$name] = $object;
}
function get($name) {
return $this-_objects[$name];
}
}
// in main code somewhere
$Registry = new Registry;
$Meetgreet = new Meetgreet;
$Notify = new Notifier;
$Registry-set('Meetgreet';, $Meetgreet);
$Registry-set('Notify', $Notify);
// in Meetgreet
$Registry = new Registry;
$Notify = $Registry-get('Notify');
I'll post a singleton when I have more time.

Thank you for your response! Your answer is intriguing, and I would
love some extrapolation!
Meetgreet is only needed on 1, maybe 2 pages, so including it globally
is not needed, and because all meetgreet business is done on a single
page, so it is currently uncessary (however I will admit it isn't
extendible this way).
So what is this registry pattern you speak of?
Thanks!
Allen

Several ways to do it. One would be to make the Meetgreet a singleton
if it really is, and then use its static getInstance. I would
probably
use a registry pattern though.

Re: [PHP] Highlighting image map on load
I'm not sure if you can use CSS alone to highlight, but if you can, just give the area a class as you output it with PHP That's the problem, area itself isn't visible, so giving a CSS class won't highlight it. -- View this message in context: http://old.nabble.com/Highlighting-image-map-on-load-tp26777088p26807008.html Sent from the PHP - General mailing list archive at Nabble.com. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
