Re: [PHP] Good way to organize code using classes???

I use PHP classes extensively and very often use classes

First off, I would make sure to take advantage of inheritence
as much as possible. I have heirarchies up to 4 deep for
some of my classes depending on how much specialization
I need while at the same time maintaining only one set
of code for functionality common to all subclasses.
As for using classes within classes, I don't include
the classes within a class definition nor within
a method def. I include the class def in the class
file but outside the actual class {} statement.
When I instantiate the class, if I will need the object
ref to pass to other classes or to other methods within
the calling class, I assign the initial object
instantiation to a class variable. That way any class
methods can have ready access to that class via the
ojbect reference stored in the class variable.
Only when I know for sure that the use of a class will
be for one purpose do I include and instantiate within
a method.
as always, YMMV depending on the structure of your project.
NOTE: There is a set of new PHP functions that allow
a sort of dynamic multiple inheritence. You can look
here for info:

Hello everyone,
I want to be able to use objects to create my future pages. My goal is
to use methods of classes to make the original front-line script easier
to read, while all the processing is done with a simple call to the
different classes from a single class. Please read futher, as I'll get
to a point and to my question...
I have many classes that do different tasks, like formValidator.class,
stringManipulator.class, db.class, fileManipulation.class,
template.class, etc (these are self-explanitory as their names suggest).
Then, I might have a class called category.class that adds, deletes,
edits, moves, and renames categories within the filesystem and database.
But I would have a front-line script called category.php that would call
the necessary methods of category.class at certain points, depending on
the task being done on a specific step.
In other words I want category.class to call the other classes and do
something with them, then in turn I want category.php to call objects in
category.class for a specific task, such as:
?php
// category.php
include (category.class);
$cat = new category ();
$cat-addCategory($new_cat_name);
// or
$cat-editCategory($cat_name);
// or
$cat-deleteCategory($cat_name);
// or
$cat-moveCategory($cat_name);
// or
$cat-renameCategory($cat_name);
?
My question is:
How can I call a class within another class and do something with it?
Right now I'm doing it the most convenient way I know, which is
including other classes using the include() function within the methods
of the category.class. There is no multiple-inheritance allowed in PHP,
so I can only use inheritance on one class.
Including new classes within the existing classes is not such a bad idea
as it ensures you to have only the necessary classes called.
I am also extremely skeptical about creating too many classes at a time
in one script. Do the above examples degrade performance speed of the
script when I call too many classes? Also, isn't there a way to use
sessions to save created classes and then use them again for other
scripts without the need to make a new instance of the same class again
and again?
yes, you can serialize/unserialize classes into the sessions. This makes
it a little more complicated, but can be helpful sometimes.
I am really looking for a better way to organize my code while still
being able to use these classes whenever I need them and at the same
time keeping the category.php file clean and easy to read. Is there a
tutorial on how to organize code? I'm not looking for html template
tutorials. Just how to get around inheritance limits while still keeping
performance and clean-code in mind.
You know what I have once done? I created a file with functions that
return you the object pointers. It would create (declare) the class
whenever it was not declared before or just return the pointer from a
global variable if it was declared before. That way, you only load a few
functions, and whenever you need a class you assign a variable to the
function's return to have the class. This limits you script to only
classes you use and no includes within the script itself. A kind of silly
method, but can be easy to work with.
Also, check out the new Zend 2 engine, it has tons of improvements with
classes for PHP5. Currently the code is in CVS (checkout php5 module).
Changes are listed here:

It is good that you are looking into classes and functions. The

At the end of your function mysql_query, add a line:

Then, when you call that function, make it like this:
$resultArray = $TemplateTable-mysql_query(select );
Now you can pass $resultArray on to a different function.

Alternatively, you can define a class variable where you
will be storing the query results and then access that
variable from outside.
so,
class foo {
var $results;
function bar($query) {
while {
$this-results[] = $row;

Then, from outside the class, you can access the variable.
$bar = new foo();
$bar-bar(select foo...);
print($bar-results);

now in my MYSQL.class- I want to send a query to my class which then
returns an array- my database row or rows.
the problem is that whilst my array is created- I only seem to be able

really want to be able to send it on to my HTML.class for formatting

I obvioulsy do not want to format any 'echoed' output from within my
databasee class.
Here is a bit of sample code-
Once my database is open I call my query like this-
$TemplateTable = new DB;
$TemplateTable-mysql_query('SELECT * FROM template ORDER BY name ASC
LIMIT 10');
This is the function within my MYSQL.class
function mysql_query($query){

while($row=mysql_fetch_row($SQL)) {
$new_row = join('***',$row);
$result[] = $new_row;
echo $result[$a].br;
$a++;
}
}
So here I am creating a string with each row in my database which is
delimted by *** - $new_row.and am placing each row in anew array
called $result.
I can evaluate and format either $new_row or $result from within
mysql_query() but I really want to do is to send it on to another
funtion or even better another class- or access the values glabbally as

Any ideas or am I missing something really obvious?

[PHP] session problems

(session_is_registered("req")) ? print("req: yes\n") : print("req: no\n");
(session_is_registered("off")) ? print("off: yes\n") : print("off: no\n");
var_dump($req);
var_dump($off);
I get a response that both $off and $req are registered variables.
however the output of var_dump for $req is null while the output
for $off shows the frozen object. If I reverse the order of the
session_register on page one, then the var_dump shows values
for $req but not $off.
I am using DB storage for the sessions. my callback functions are

G'day PHP'ers
I am trying highlight the results from a search, so far I have this
working but only if the string is an exact match ie: case sensitive, for
example:
?php
$keywords = "foo";
$data = "This is a lower foo. This is an upper FOO. This is a ucase
Foo";
$lower = strtolower($keywords);
$upper = strtoupper($keywords);
$ucase = ucwords($keywords);
$words = array($lower, $upper, $ucase);
while ( list($key, $val) = each($words) ) {
$hilite = "font color=\"#ff\"" . $val . "/font";
$replaced = ereg_replace($val, $hilite, $data);
}
echo $replaced;
?
Now as metioned this seems to work only for "foo" does anyone have any
idea why?
Also I need to be able to support mutiple keywords ie: foo Foo FOO, so
basically I know I could split(" ", $keywords) then some how traverse
the array making a new array of all possible case combinations then in
my while loop replace each occurance found in $data with the highlighted
replacment, sounds easy hmm
If anyone has any ideas or can see what I am doing wrong so far, it
would be mutch appreciated.

or

if you use the POSIX regex fields.
hi, im trying to fix this couple of hours but i couldnt find the
mistake... can somebody look at it...
first i want to check the $co_area for 3 digital ... it must contain 3
digital
if ($co_area != !ereg("([0-9]{3})",$co_area))
{ echo " * Area code must be 3 digital"; }
second...
nickname check works but the first letter could be any number or any
letters
with this code it accept only letters as first character... i just
want any letter or numbers or - _ symboles from 3 to 12 characters...
if ($nickname != !eregi("^[-\._\.0-9a-zA-Z]{3,12}$",$nickname))
{
$error ="Nickname must be Alphanumeric[ a-z 0-9; - _ ; 3 - 12
characters ]";
$flak=1;
}
First mistake when using character classes in the pattern is that the
hyphen must be at the end if it is to be included. Otherwise the hyphen
is seen to be part of the range (0-9 or A-Z):
so, ^[0-9a-zA-Z._-]{3,12}
instead of what you have. You also should not need the trailing $.
As in the first example, don't use the 'double negative' approach.
use:
if (eregi("^[^0-9a-zA-z._-]{3,12}",$nickname)) {
echo "only alphanumeric buddy!";
}
I didn't test this but it should be closer to success.
Jeff
i hope someone can help me to fix this...
thanx

If you wish to include a hyphen in the allowed character list of a
pattern match, you must include it as the last character.
So what you want should be more like:
if (eregi("[^a-zA-Zëàéêêàäïüöûâç-]",$name)) {
print("your name can't include non-letter, etc");
}
You can add space with: [:space:] within the charachter
class ([^a-zA-Z[:space:]ëàéêêàäïüöûâç-])

I tried something like this and your examples worked:
$str = "tag element = \"value\" nextelement";
if (eregi("=[[:space:]]*\"([^\"]+)|=[[:space:]]*([[:alnum:]]+)",$str,$regs)) {
print("yes - ".$regs[1].":".$regs[2]."br\n");
}
since the pattern has an 'or' (|), you have to look in either the second
or the third element of the array you use to store values from the ereg.
Jeff
can anyone help me figure out a regular expression to find the value of
a tag element?
for example:
tag element="my value"
tag element=value
tag element="my value" nextelement
tag element=value nextelement
tag element = "my value"
tag element = value
tag element = "my value" nextelement
tag element = value nextelement
so in each of the above i need to find either "my value" or "value"...
i tried this but it wont work for every situation:
ereg("element[ ]*[=][ ]*[\"]?([^\"]*)[ |\"|].*" ...
thanks for your help - regular expressions are not my best area!
jamie.

Re: [PHP] Netscape differences?
In article [EMAIL PROTECTED], "Joel Dossey" [EMAIL PROTECTED] wrote: One way to fool browsers when making an image request is to append a random string to the query string of the img src. In these situations, adding 'rand=?php print(time()); ?' can do the trick. Jeff Greetings, I have a php script that generates a random image. All images are kept in a mysql table. It works fine when viewed by IE, but Netscape, and Lynx, always show the same image. The database information, however, is changed as it should be (correctly incrementing the times seen column for the image), and on refresh all information goes as it should, except for randomly selecting an image. This may be an apache caching problem, but I was wondering if anyone has run into this working with php in general, and what solutions I need to explore. Thanks much, Joel Dossey __ Do You Yahoo!?
