Why is it in a class, so important for you to initialize your $variables?
In the following example, I have my class started and then took out or
atleast commented my "var $variable" and the code still does what it should.
So why is it so important that you initialize these variables this way?
[:::CODE:::]
<?php
class test {
//var $z; <------This is the part I don't see
the relevance in doing as here this is
commented out and the class works as expected.
function z(){
$this->z = 250;
return $this->z;
}
function test1($a,$b){
$this->tested = $a + $b;
return $this->tested;
}
function test2($c,$d,$e,$f){
$this->test2 = $c + $d;
$this->test3 = $this->test1($e,$f) + $this->test2 + $this->z();
return $this->test3;
}
}
$whynot = new test();
echo $whynot->test2(10,10,10,20);
?>
[:::/CODE:::]
I don't have any real use for this code to work after this point, I'm just
trying to generate somesort of script that makes sense to me. As my previous
attempt at jumping feet first into classes failed miserably.
I guess I'm just confused on why you would want to initialize a variable and
not assign a value to it if you know what it is? Like in my Database class,
I made my username, pass, localhost, etc variables initiated with their
values, but kept getting errors from mysql that I didn't have a "Valid"
mysql resource. I guess after reading this in 4 books and on php.net, they
all do this but none of them go into WHY it's so important.
Part of my concern is that I'm being told, or atleast reading that you
initialize them for the class, but if the class structure is already in
place for the variables inside each method to be local to that class, I
don't see the relevance for initialization. Man this sounds dumb cuz I just
know there's a reason, I just can't find it. Any help would be appreciated.
Thanks.

Defining a variable in a class using 'var $z', keeps some sort of
structure for the class. PHP has always kept the creation of
variables simple for the programmer and classes arn't an exception.
You will find, however, that most classes you'll see will have the
variables defined.
PHP5 actuall expands on the declaration of variables, it adds a
few new ways to define variables:
class test {
/* Accessable to any body */
public $public_var;
/* Only accessable to any instance of 'test' or
any class that inherits 'test' via Extends */
protected $protected_var;
/* Only accessable to instances of class 'test' */
private $private_var;
/* the static keyword makes this variable shared accoss all
instances of 'test'. and is applied to either public,
protexted or private scope */
static public $static_var;
These keywords can also be applied to the declaration of functions
ie:
public function test_func() { }

What are you using to access the soap server? If you use the modules such as
NuSOAP or SOAP built in for PHP5 you wouldn't have to worry about the
response header.

HTTP_REFERER is empty because the page was not called from a link? Or
HTTP_REFERER is empty because the browser doesn't supply the value?
Echo the variable and see what you get.

I echoed it, and got a blank variable...
We ahve full admin rights on my server, and the one we're checking the
referer from...
Basically, our system has an exsiting user database, and we wanna allow
users to loging as per usual, and but allow them (and only them) to veiw
pages on the new server...
I just thought that htt_referer was the easiest way to do that, as I only
wanna let people in, who have signed in on the first server first..
Am I making any snece?

Because the substrings can contain any char-s including
commas. Also I use reg exp not for splitting only but
for validating whether whole string and the substrings
are correctly formatted. Using reg exp requires much less
coding than traditional programming.

Hi,
This isn't working:
$text = preg_replace('/<!--(.*)-->/','',$text);
Can someone advise what characters I need to escape, or whatever to get
it going?

Hi,
You must escape "-" (minus sign) because is a
meta-character for regular expressions. See
http://www.php.net/manual/en/pcre.pattern.syntax.php.
Your line of code might be:
<CODE>
$text = preg_replace('/<!\-\-(.*)\-\->/','',$text);
</CODE>
This line of code, if you are parsing HTML file row by
row, strips only "one line" comments. Comments spanned
on multiple lines are unaffected.

Well, what do you want it to do? On my system that properly replaces the
entire commented string with nothing. An example which puts something
else there instead:
<?php
$text = "<body>\n<h1>Hi</h1>\n<!-- foo --></body>\n" ;
$text = preg_replace('/<!--(.*)-->/','blah',$text) ;
print "text is .$text.\n";
?>
This yields
text is .<body>
<h1>Hi</h1>
blah</body>
.
as expected.
Note that since you're just replacing the entire comment with '' you
needn't bother with the () around whatever may be in the middle, too.

From that same link:
Part of a pattern that is in square brackets is called a "character
class". In a character class the only meta-characters are:
\
general escape character
^
negate the class, but only if the first character
-
indicates character range
]
terminates the character class
So you only have to worry about a minus if you're in a [a-z] range, and
even then you can put a minus in without having to resort to backslashes.
% Your line of code might be:
%
% <CODE>
% $text = preg_replace('/<!\-\-(.*)\-\->/','',$text);

Then, again, it might not ;-)

Agreed. Let's leave that to the student to work out, shall we? :-)

$text = preg_replace('/<!--.*-->/su','',$text);
The 's' modifier will allow the expression to pick up multi-line comments by
allowing the dot character to match newlines and the 'u' modifier makes it
'ungreedy', so that if you have
<!-- comment 1 -->
HTML example
<!-- comment 2 -->
only the comments themselves are matched and not everything from the first
"<!--" to the last "-->".

First off thanks Curt for the attempt at explaining what the purpose was for
those, I'm convinced enough to start doing that since that's what the "pros"
use. :)
However, I know have another concern. As for as class security. Is it wrong
to initialize the static variables for my database assignment class ie..
[..Example..]
<?php
class db_connection {
var $user = "dbuser";
var $pass = "dbpass";
var $db = "db";
var $host = "localhost";
var $connection;
....?>
[../Example..]
or should I still be using the normal seperate file for those values ie...
[..Example2..]
<?php
include_once("dbconn.php");
class db_connection {
var $user;
var $pass;
var $db;
var $host;
var $connection;
...?>
[../Example..]
Where in the included file I have the variables listed as
$user = username;
$pass = password;
etc.....
The Class files that I am creating are going to be seperate "template"
includes if you will where they also are going to be "include_once()" items
aswell. Is it over redundant to have both of the files includes?
Any help is much appreciated as I'm still learning this exciting language!
:)
TIA,
Wolf

More often than not it's a good thing to assign 'default' values to
class variables like that.
In this case though I've observed that common practice is to get the
user/pass values from a config file and pass them along as variables
when creating an instance of the class.
Classes are most beneficial if you can take your class include file
from one project to the next and just pass along different parameters
and they work. Including user/pass would force you to edit/change
those values on every project you use that class in.

True, I do realize that classes are "suppose" to be as portable as possible.
I just wasn't sure from a security stand point that if the dbconfig file is
in with the dbclass file, if it really made a difference since they are both
off of the webtree and being "included" if you will. :)
I much appreciate the feed back. Thanks for your time.
Man PHP ROCKS!! However I only feel that I've only begun to scratch the
surface of it's power. I still haven't done file uploads and directory
listings yet, soon Danielson.....soon.
And the sad part is...sigh, I've just finished a b.e.a.utiful login script
for one of my client's and now I need to rewrite it so that it's a class,
cuz heck I want it for my site too.
$smiley = ":)";
include_once(evil_laugh.php);
echo $laugh $smiley;
//Echo'd: Muuuhahahahahah :)
Thanks again. :}

I'm defining things like DB access values as constants in my config file
rather than as global variables. This way I can make absolutely sure that
they are not accidently changed anywhere in my application. As constants are
globally available you don't need to pass them to every class method that is
using them.
<?php
class db_connection {
var $user = CONFIG_DB_USER;
var $pass = CONFIG_DB_PASSWORD;
var $db = CONFIG_DB_NAME;
var $host = CONFIG_DB_HOST;
var $connection;
....?>

Hi List,
Sorry for this being way off topic but I need some help with a MySql sql
update.
I have a date column and have added a datenew column and want to do a table
wide update to make datenew 1 year more that date.
So:
Date = 2003-05-06
Datenew should be 2004-05-06
Each row should update the datenew for 1 year more that date col value.
Thank you for any help you may give and once again sorry for being ot.
Dave Carrera

UPDATE yourtable SET datenew = dateorig + INTERVAL 1 YEAR;
Although... if "datenew" is always one year more than "dateorig", why would
you need another column?
SELECT dateorig, dateorig + INTERVAL 1 YEAR AS datenew, ... FROM ...

tried the mysql manual??? its got the date_Add function
DATE_ADD(date,INTERVAL expr type)
from manual:
mysql> SELECT DATE_ADD("1999-01-01", INTERVAL 1 DAY);
-> 1999-01-02
mysql> SELECT DATE_ADD("1999-01-01", INTERVAL 1 HOUR);
-> 1999-01-01 01:00:00
If you use really incorrect dates, the result is NULL. If you add MONTH,
YEAR_MONTH, or YEAR and the resulting date has a day that is larger than the
maximum day for the new month, the day is adjusted to the maximum days in
the new month:
mysql> SELECT DATE_ADD('1998-01-30', INTERVAL 1 MONTH);
-> 1998-02-28
hope this helps
Angelo
