Greetings all,

I am running version 4.3.4 of PHP.
Fairly recently. I am trying to call a pretty basic programming tool.
Maybe I am just really tired, or something but I am not getting what is
going on.
Is there something I am missing.

I am pulling a SQL call on a date to get the month. I am using Date_format
and the %c to get the Month in numeric format.
The I plug it into a variable and my intention is to call it as the index
of an array.
Nothing prints.

When I turn on all notices I get a notice that it is an undefined index.
What the heck is going on??

Thanks

Phillip

Sorry, left my mind reading helmet at home today. How about sharing some
code.

Here's how I do it.....

User table in mysql

UserID, username, password, admin, read, write
1001, John, *#&(&(, 0, 1, 0
1002, betty, KD)&#(&S, 1, 1, 1

Create a login form.

Get their username and password,

Run a query to pull the record where username and password match

If the username is in the table and the password is correct then

$_SESSION['userid'] = UserID (pulled from db query)
$_SESSION['admin'] = admin
$_SESSION['read'] = read
$_SESSION['write'] = write

Then create a function to check permissions based on the session
variable.

For instance if a page has a form for editing information, before
loading the form check to see if the
Current $_SESSION['write'] variable is set to '1', if so load the form,
if not then don't.

May not be the best way of doing things but it works well for me.

I'm still fairly new to PHP, so there may be a simple fix for my
relatively trivial complaint.

I'm using an included page as a head section. It works fine, except that
when preview a page and view the source, all the style sheets are
displayed on one looooong line, like this:

</script><link href="../../css/ref.css" rel="stylesheet"
type="text/css"><link href="../../css/na/a1.css" rel="stylesheet"
type="text/css" /><link href=".css" rel="stylesheet" type="text/css"
/><link href="../../css/nations.css" rel="alternate stylesheet"
type="text/css" title="Nations" />

It looks like they won't scroll across THIS page, so here's a more clear
example:

What I want is a normal style sheet display, like this:

Do you know what causes this and if there's a fix? I posted some code
from the head section and main page below.

Thanks!

You need a \n at the end of each line inside the quote
like
echo "<stylesheet>\n";

\n is newline

Thanks for the tip. However, I must be doing something wrong. \n didn't
work, so I searched Google for PHP + "new line" and found a page that
said you have to use \r\n if you're working on a Windows platform. But
that doesn't seem to work, either. (If you do use a special new line for
a Windows computer, then publish your website to a Linux server, will
that cause problems?)

Do I need to modify the new line code because my echo statements are
enclosed in single quotes (' '), rather than double quotes (" ")?

I pasted my entire include page code below. Thanks!

"newline"-character should be inside double quotes ("\n").

For example:

instead of:

echo '<link href="' . $periods . 'css/nations.css" rel="alternate
stylesheet" type="text/css" title="Nations" />\r\n';

use:

echo '<link href="' . $periods . 'css/nations.css" rel="alternate
stylesheet" type="text/css" title="Nations" />'."\n";

Hope that helps. :)

Another way you could go, as this is mostly HTML with some PHP values thrown
in, is to write it as such -- then all your newlines are present exactly as
they appear. This would look something like:

<?php
$todayDate = date("m-d-Y");
?>
<title>Freedomware > <?php echo $myname ?></title>
<meta name="description" content="<?php echo $myname ?> versus
  Microsoft" />
<meta name="keywords" content="<?php echo $myname ?> versus
  Microsoft" />
<meta name="mssmarttagspreventparsing" content="true" />

It sounds like you have figured out the problem, however I thought I
would share another method that I like to use in similar situations.

<?php
$todayDate = date("m-d-Y");
print<<<END

<meta name="keywords" content=" $myname versus Microsoft" />

<script language="JavaScript" src=" $periods js/sort.js"></script>
<script language="JavaScript" src=" $periods js/ss.js"></script>
<script language="JavaScript" type="text/JavaScript">
END;
?>

there is one pit fall on this method that I run into sometimes. If your
code is indented like it should be that moves the "END;" away from the
beginning of the line and it won't work. So this wouldn't work,

while(for a while){
    if(this){
        do stuff;
        print<<<END
        bunch of stuff here
        END;
        do more stuff;
    }
    end of while
}
The "END;" must be the first text on the line, so it has to be like this,

while(for a while){
    if(this){
        do stuff;
        print<<<END
        bunch of stuff here
END;
        do more stuff;
    }
    end of while
}

Maybe i've misunderstood the question, but U can check variable

Hi all

I have a winXP machine on a network running IIS (PHP and MySQL is installed)

I have recently moved from one machine to another and after setting up IIS
and the rest and try to run few PHP scripts they just run forever or
timeout. I believe the problem is with the security permission on ...
somewhere, since I've been doing the same setup in several machines and it
works fine (not in this network).

Now, the funny thing is that most simple php script run fast after playing
with the permissions but more complicating scripts or the phpMyAdmin just
timesout.

Does anyone know what the hell is going on?

Mario,

Please don't reply to a message when you want to ask a question compose
a new thread instead.

Anyway from what you have described it sounds like you have a firewall
that's blocking the mysql port. Somefirewalls just drop the packets
instead of denying the connection. That way the script just hangs an
eternit waiting for a packet that never arrives. Try stopping your
firewall completely .

Anybody know of any PHP based Social Software projects?

attached mail follows:

This is a long one - I'm trying to get to grips with my understanding of
OOP.

I'm not sure that I understand object oriented programming as well as I
could to benefit from using it in PHP. Although I've used it to produce
working applications, of the few objects I've produced nearly all have
carried too much weight and functionality (one object for both HTML
generation and DB interaction etc) and several have been extensions of the
others.

I was hoping someone might be able to check my logic.

One of the main functions of the application I'm working on at the moment,
my first use of OOP in PHP, is to iterate through a hierarchy of retail
outlets and extract information from a database based on each location in
the hierarchy. A template SQL statement is parsed and parts are replaced
with information from the hierarchy. This query is then executed, and the
results are placed in a table within a static HTML file stored in a
directory structure which mirrors the structure of the retail outlet
hierarchy. I've done it this way because the traffic to the site is
expected to be high and the information changes infrequently, so static
pages will ensure good performance.

The way I've written the application isn't up to much IMO, using objects in
a primitive way akin to a PC newbie using the CD ROM drive as a coffee cup
holder - ie. does the job but it's not quite how it was intended to be
used.

I've got one big object (treeMapper) that does everything, which includes
(over and above the database functions, file input and output, HTML
generation and string formatting). It has two main methods. Process() and
taskMaster(). The first method iterates one unit through the hierarchy and
then calls taskMaster() which takes values Process() has changed in the
object and uses them to query the database and to format the results into
an HTML table and output to a file (as described above).

In the code for the class, taskmaster() is empty. When I want to use the
class, I create a new class which extends treeMapper and then overrides the
taskMaster function. In this way I get an object which I can reuse for any
report which needs to be made for every store. It works and it's fast, but
this method seems really WRONG!

I started developing this six months ago as a first project in OOP in PHP,
and am starting to see it's limitations - for instance, I need to use the
DB functions for other small tasks on the site, which involves
instantiating a new treeMapper (which is highly inefficient as I won't need
the other 20 methods.). I've also got some handy string manipulation
routines which can't be used without instantiating a treeMapper. So I want
to break it up into smaller chunks, smaller objects which can talk to each
other.

From what I've read, I think I should be using an iterator pattern to
design an object which JUST does the iteration, a database object which
JUST does queries from the database, another iterator object which JUST
does iteration through database results and another object which draws
graphs based on results from the database.

My question is (I know you've been waiting) how best to connect up these
objects, as I only really need one instance of each object for my
application. PHP 5 objects seem easier to deal with (none of this
incomprehensible & notation) and I want to know whether the following is a
good way of doing it and how other people might go about this.

class dbObj
{
var $results;
function dbObj()
{//set up DB con}
function execQuery()
{//ODBC query exec - results put in $this->results}
}

class iterator
{
var $currentPos
function iterator()
        {//loads data into iterator}
function reset()
        {//Resets pointer}
function next()
        {//steps forward one item, changes $this->currentPos to whatever.}
}

class HTMLGenerator
{
function HTMLGenerator($dbObj, $iterator)
        {
                $this->dbObj = $dbObj;
                $this->iterator = $iterator;
        }
function MakeHTML()
        {// as you'd expect.
        // refers to $dbObj and $iterator (objects passed by reference in
        // PHP 5)
        // $iterator->currentPos used to parse SQL query
        // eg. $dbObj->execQuery("select...");
        // eg. $dbObj->results used to make HTML;

// }
function outputToFile()
{//Saves to File}
}

The main application would then do this:

$q = new dbObj;
$x = new iterator;
$y = new HTMLGenerator($q, $x)

while ($x->next())
{
$y->MakeHTML();
$y->outputToFile();
}

Anyone got any thoughts about whether this is a good way to do it? I was
wondering whether instantiating objects should be done within other objects
that need them - if this can be done - but I would only do that in cases
where (for instance) an HTMLGenerator object is instantiated without any
parameters, in which case some logic could be added to do this.

Thanks!

Hi Chris,

Sounds to me like you are pretty much on the right track bearing in mind
that PHP is not the bes language to learn OOP. Even your taskmanager
sounds good, i wouldn't bother with reading up on design patterns just
yet. They are indeed very important and you should definitely study
them, however having spent an year or more doing OOP helps you
understand them better. (others will disagree).

Don't worry about classes become too big either if all the code belongs
in one class it can't be helped. If you look at a fairly large java
program you will find classes that range from 20-30 lines to 2000+ lines.

Here is my advice, check out the pear code, it will help you dearly get the
grips of how to setup classes. IMHO i feel pear is a standard, i use most of
the standard but i dont particularly write classes for pear but structure it
similar, but am thinking of porting my error code around pear. Classes are
purely packages which are reusable within projects, try not to get simple
functions with complete classes mixed up, it may not be needed to make a
class at all. Hope this helps.

Yes i think java would be the best to learn proper OO, i've nevr done it,
but coming the other way knowing php OO, java became more familiar to me,
i'm gonna do it this year. With PHP5 coming out that all may change
slightly.

May i ask though, what is the point of a destructor and is it really good to
add it in, does it work in php4 ?

    Looks like you might enjoy reading Design Patterns by Gamma et. al.
    (ISBN: 0201633612). It's not easy reading, but will quite likely
    open your eyes. I've had many forehead-slapping moments since I
    started studying it. It's somewhat C++-centric, but the patterns
    are usable in other languages as well (and PHP can be seen as a
    dumbed down version of C++).

Wow, that's a lot of stuff in one class. Personally, I've started using
the MVC (Model, View, Controller) architecture. Basically what it does
is seperates Data logic from Display logic and Control logic. Here's how
I've been using it.

Model: Holds and deals with all data for the program, such as database
connections / queries, session data, data consistency. I am currently
using classes which use PEAR DB_DataObject for DB connections, querying,
and data storage.

View: Deals with displaying of data from model. ONLY does displaying, no
processing. Very minimal logic only associated with outputting.
Currently, I am using Smarty entirely for the view. Little no no PHP
code, only Smarty. The View in this case is just a smarty template file.

Controller: Handles requests from the browser. Instantiates Model and
View, calls functions in Model to alter its state (updating from
$_REQUEST vars, for instance). Chooses a view and then tells the view to
display. For me, this is all home-grown PHP.

This architecture can be much more complicated in, say, a C++ program,
but the Server/Client pattern built into web programs makes it much more
simple. The reason that I use this particular architecture is that it
factors all of the pieces of your program very nicely. Later, if you do
things right, you can use a single screen from one program in another
with minimal editing.

Here's a few pages that discuss MVC:

I've been using JavaScript style switchers combined with "alternate
style sheets," allowing users to control the appearance of my web pages.

However, I recently read that you can make style switchers with PHP -
which are allegedly superior to JavaScript style sheets. Then I found a
PHP style switcher at
http://www.contrastsweb.com/switcher/v2/example.php that has an added
advantage; you can apparently choose several style sheets independently
of one another. For example, you can change the background color, then
change the font.

I'm working on some complex tables that I'd like to control with such a
multi-style switcher. Suppose I have five style sheets, named One, Two,
Thtee, Four and Five. I'd like to set it up so that a visitor can view
the page with any one of these style sheets, or with a combination
thereof, such as One, Three and Four or Four and Five.

At any rate, I couldn't get the PHP style switcher above to work. (See,
also, http://www.contrastsweb.com/switcher/v2/)

I just wondered if anyone on this list has worked with PHP style
switchers and can recommend other tutorials or different strategies.

Thanks.

Yes, but you need to force PHP to re-evaluate the string you retrieve from
the database -- normally, PHP just uses values retrieved at runtime as-is
and doesn't do any special interpretation on them.

The function you need to do this is eval() (http://www.php.net/eval), and
one possible way of using it to achieve your desired result is (off the top
of my head, untested):

eval('echo "blah {$row[\'thecolumn\']} blah";');

Possibly because they didn't want to get into the security issues involved.
It sounds like you're ok there, as you only intend putting very controlled
values into the database.

The problem comes if you're potentially eval()-ing user-supplied values that
have been insufficiently validated. Just suppose, for example, that it was
possible for a user to somehow get a value such as 'system("rm
/etc/passwds")' inserted into the database in a field that you then
eval()...

Cheers!

Well, I would have mentioned eval(), but you have to put PHP code in
there instead of just strings. For example, "Hello $name." would have to
become.

'return "Hello $name."';

'return \'Hello \'.$name.\'.\'';

If you eval a string with "Hello $name." in it, you will get a parse
error. For readability, I would think that using str_replace to replace
specific variables would be better.

Actually, it would be even better if you used a templating system to do
this kind of thing, such as Smarty. That way you don't have to worry
about variable replacement, but your strings can still be easily edited.

For a regular expression example of how to do this:

<?php

$str = 'this is $name a $test';

$name = 'John';
$test = 'foobar';

$evaled_str = preg_replace('/\$([a-z0-9_]+)/ie','\$\1',$str);

echo $evaled_str;

Where "$str" is what's retrieved from the database with the "variables" in
it.

Why not start with the king of OOP, C++? Currently C++ is the most

Hehe, and here is where we start a holy war.

I would have to disagree. While it may be possible to implement good OOP
in C++, it does not nearly implement OOP as well as many other
languages. It also has many other design problems that hinder the
learning of OOP.

However, if you know C++ already it may be easier to learn good OOP in
C++ (it has much more full OOP than PHP4).

Python, Ruby...?

Of course, I've never done any OOP in C++. My guess is part of the reason
he said this is because you've got to learn C++ before you're going to do
much successful OOP with it. Not exactly a small learning curve.

Other languages dispense with a lot of the formalities found in C++ (a
good or bad thing, depending on your perspective). I found Python to be a
great language to learn OOP, since it forces good habits on you.

C++ is a very large unwieldly language - it has too many constructs and
too much syntax. Experience has chown that smaller simpler languages are
easier to learn and apply than larger ones. This is why C is still the
language of choice for a lot of systems coding (among other reasons).

While purists will no doubt damn me to hell, I know a lot of people would
put C++ at the bottom of their list of OOP coding languages of choice.

No I couldn't because we have to use 1,6 Mio values direktly. If we read
them each for each it will take a lot of time.

We discover we can use an Array with 2.000.000 Values - if higher the server
(Intel 1 GHz, 32 Bit, 1 GB RAM) gives up.

Without testing I can't be sure, but my past experience suggests that
working with several smaller sets of data one at a time would be more
efficient than working with one big one if that's possible. I could of
course be wrong since I don't know the internals of PHP too well, but
I'd be surprised if I was.

not sure I understand 100% what you mean.

You could send a cookie or form field to the browser with the session
id.

You could serialize the $_SESSION array and send that to the browser.
There are a bunch of options.
