[PHP] [PHP5] Super constructor?

[FrzzMan]

Hi guys, hey don't laugh at the subject, in fact I don't what to call 
it, so let's call it super constructor :D

Let's see following code...
class Base
{
__construct()
{
// Do something
}
}
class One extends Base
{
__construct()
{
// Do nothing
}
}
class OneMore extends One
{
__construct()
{
// Do things :D
}
}
So when I create an instance of OneMore class by:
$OneMoreInstance = new OneMore()
The __construct() method of class OneMore will be called, not the one of 
One and Base, right?

So is there any way around to make the Base class have a contructor that 
will be called everytime one of its child initialize?

My problem, I want all of the classes in my object are extend from one 
base class, so they are all have some common properties and function, 
but PHP won't implicit call the contructor (that's the right way)... 
btw, in my case, this is bad, as bad as every constructor would be called...

Well, hope you understand what I'm trying to say...

[PHP] Cookie Security?

[phpmail]

My login script sets unique, secure, cookies that identify the user. Some of my pages 
only display content if a secure cookie is present. Is this a bad idea for secure 
pages with sensitive details as I have heard that cookies can be faked? I am always 
interested in creating a secure environment for my website visitors and I want to make 
sure I am protecting their privacy. Any help on this matter is greatly appreciated.
 
Thanks,

I think you're on the right track with using tidy's php5 features.
Here is some more documentation on tidy, hopefully it will push
your approach in the right direction:

[PHP] Re: Best Lossless Hi-Res Photo Storage with PHP

[Kim Steinhaug]

well, there are formats that have impressed me. The Mpg-4 format
which requires plugins all over the place is really amazing, from e-vue.
They also provide a plugin atleast for IE to browse the images.

I dont know if you can compress images outside the windows platform
however.

If your looking for supreme quality however, you would need to stay
away from the lossy formats and probably go for TIFF which is a great
format and is also supported by any major software. PNG however is
abit "strange", woudnt sendt PNG images to a publisher...

You could ZIP the TIF images on the HD to same space, you often
get good results on this. This would also make the downloads better
for the user, and since all the browsing online would use thumbnails you
dont need to waste CPU do depack the images, since you all users
can depack a ZIP file (thats the least you would expect from a user that
purchase a High resolution image).

Ive created such systems myself, and my sollution was another :
Plug in a new harddrive. We save the images as jpg, tif, eps, ai or whatever
the original image was created as, and create thumbnails at various
resolutions in high compressed jpg for fast browsing. Often I tend to
ZIP the lossless images aswell, but then again I dont need to since HD isnt
a problem atleast in my case.

Hope this helps.

[PHP] Multidimensional Array advice from a newbie

[grahama]

Hi :)
I am creating an XML file out of a mysql query with nested arrays.
Currently I can get 1 element and 1 child with a properly formatted XML 
file with the below script .

My question is: How do  I  add 3 to 4 more child elements to the below 
'playlist' array ?
Currently ,I have one parent 'Artist' and one child 'english' ...
I need to add more child elements to the 'Artist' array like urlPath, 
spanish, biography, etc

My addled thoughts...
So, would the multidimensional array be like:
$playlist[   [$artist [ ]   ][$media[ ]  ]	[$mediaElement]  
]?

for the  'trackName' child:
$playlist [ "Artist 1" ] [ "Track 1" ]   [ "trackName" ]
or for 'urlPath' child :
$playlist [ "Artist 1" ] [ "Track 1" ] [ "urlPath" ]
Do I have to add another dimension to the 'playlist' array? Do I need 
another  foreach loop ?
Is there an easier more efficient way to do this?
Be nice to spell out the schema in some way in the script...in case you 
need to add more levels...like a 'subCategory'

I am a bit new to this so any help would be greatly appretiated  
head is spinning a bit


$sql = 'SELECT artist.artist_name, media.english, media.path ';
$sql .= 'FROM media, artist ';
$sql .= 'WHERE artist.artist_id = media.artist_id LIMIT 0, 30 ';
$result = mysql_query($sql);
while ($row = mysql_fetch_array($result))
{
$playlist[$row['artist_name']] [] = $row['english'];
//would like to add more children here...
}
$xml = "\n";
foreach ($playlist as $artist => $media)
{
$num_media = count($media);
$xml .= "\n";   

$xml .= "\t\n";   
$xml .= "\t\t".$artist."\n";
$xml .= "\t\n";  

$xml .= "\t\n";
foreach ($media as $mediaVal)
{
$xml .= "\t\t\n";
$xml .= "\t\t\t".$mediaVal."\n";
///add more children
///add more children
$xml .= "\t\t\n";   

}

$xml .= "\t\n";   
$xml .= "\n";  
}
$xml .= "\n";
print $xml

[PHP] Re: array_rand() not random

[Kim Steinhaug]

Hmm... Ive been having same problems with mysql and picking random
numbers, I ended up having to program a rather more sofisticated
system to eliminate the stats you were referring to.

You could, not that it will be any better, try another approach :

Something like :

$count = count($your_data_array);
$random = rand(0, $count);
echo $your_data_array[$random];

PHP is maby using the same random function for both the array_rand and
rand for all I know but its worth a go.

The harder way would be to include an internal counter for your elements you
want to be randomized, so that when an item is selected you count it. Then
the
next time you calculate the random element you take the accual hits into
meassure.
There are like a 1000 ways to do this so use your imagination.

One way could be to use some sessions, and when a user hits the page you
precalculate the random sort for all your elements, and store that in the
session.
Then for each and every visit form that visitor you just go along with the
pre-randomed
data. This way your user will get a truly randomized experienced, and youll
be showing
off all the elements even if the random function in itself is abit
"non-random".

Im sure there also exists a mathematical approach calculating a sort of the
elements based
on the earlier views (meaning that we count each view).

[PHP] Re: export from mysql to csv file

[Kim Steinhaug]

You are also probably using PHPMyAdmin, if not you should be using this.
Exporting to CVS is fairly simple, and if your used to quering the databsae
you should be able to do this very easilly yourself if your looking for a
sollution you can do from scripts.

Basically what you do is simply do a "select * from table", which will give
you
every coloumn of the database, Thereafter loop through the entire dataset
and use the mysql_fetch_array function, then use this :

foreach ($temp AS $key=>$value){
 // $key   = coloumn name
 // $temp[$key]  = coloumn value
 if(!is_numeric($key))
 echo $key . " : " . $temp[$key] . "";
}

Where $temp is the $temp = mysql_fetch_array($dataset_from_query);

If your into >100.000 entries in the database you will need to do some
smart quering, or alter the php.ini to handle more than the standard 30
sec timout. Basically you could also go in "rounds" of limit 0,5
thereafter
limit 5,5 but that wasnt your question.

If you just want an empty funciton anyway, why don't you just put an

yell at you when you don't want to do antyhing with it anyway.

When I said "will do nothing" I was meaning the method call, not the 
entire script. I can't put anything into an abstract method, it only 
defines the method name and argument list, a body is nto allowed in an 
abstract method.

Upon further reflection it appears that the abstract method is what I 
really want. I'll just have to implement an empty body.

[PHP] finding text strings in html code

[Kathleen Ballard]

I am beginning a project that will involve moving data
from an mssql table to xml files.

In addition to fixing non-xml compliant html in the
text fields and outputting the data to a new xml
format, I need to find certain chunks of text marked
by standard html comments at the start and end,
comment out everything between the comments, and
insert the found text into its own xml element (which
will in some cases be inline).

I have played with code using substr/str_pos, running
html tidy with exec() and it works.  But searching the
archives, it seems like the new html tidy tags in php5
will be more useful.  In most cases the target text is
in a one row, one cell table. 

Any advice on how to attack this would be appreciated.
 I can handle the coding, I just have a feeling I am
approaching this from the hard way.
