It really depends on how you're running them.. is PHP or Perl running in
mod_* or is it running as a CGI?

Which is quicker to program in?

Yahoo uses php for some of their stuff, I would say that is a pretty
high traffic site.

[PHP] weekly email idea

On some of the general lists (like I am on the python list), they have a
weekly email that someone puts together and sends out to the list with
tips and urls to things found throughout the week on the mailing list.
People post valuable links and information and it would be a quick
overview of the past week in URLs/quotes/etc.

I'd be happy to take this on initially (the python passes it around to
the more active people every once in a while), just wondering if you
think it would be worthwhile or not. We could even have, best
javascript question of the week section in the email. ;-)

Thoughts? I looked over the past several months and saw nothing like
this happening so I thought I'd put the idea out there and would be
happy to try it out for a few weeks. I don't think one email a week
would flood our inbox so any other concerns, comments or suggestions?

Cheers,

-Robby

OO programming is definitely not a new way of writing programs.

 SIMULA I (1962-65) and Simula 67 (1967) are the two first
 object-oriented languages. Simula 67 introduced most of the key

For future reference, just about any function that uses is at the

This should apply to all the php included functions that start with is.

foo Object

[bar] = Array
(
[One] = 1
[Two] = 2

 Is it possible to add methods dinamically to an object instance in same 
 way? how? will these methods have access to private and protected

 4) database + dedicated =  err.. stupid? ;)

I should have clarified this more as to why I prefer the DB storage
method. I don't expect that my web application will be the only
interface to the data that I am storing the database. For some clients,
we build pyton interfaces that clients run on their desktop. We also
replicate our databases across a few servers and it's much easier to
keep track of the database than it is to make sure a bunch of
filesystem-stored files are too. Some of our client database machines
don't have a webservers so we don't program with just the web in mind. 

With storing in the database, we get transaction support and we know
that an image will not be deleted if it is being referenced by another
piece of data. Speed versus data integrity is something we have to
juggle per client as to what is more important. If you know how to
optimize your database (a stock pgsql db can be rather slow..) then the
speed differences are not enough of a factor for us to know that our
data just a bit more safer.

My guess is that your browser isn't set to cache .php file output. If
it's caching images, you might need to trick it into thinking that it's
an image.

for example, look at the mod_rewrite rules at the bottom of this blog
post.

http://blog.planetargon.com/index.php?/archives/27_Displaying_image_from_PostgreSQL_large_object_with_PHP.html

I don't know if this *is* the issue, but it's my first guess.

 then process the query string to extract the info
 
 You could even add a dummy value at the end like
 src='gif.php/name=$picname/type.gif to make it look like a gif'
 

In my .htaccess file, I have placed the following :

RewriteEngine On
RewriteRule ^images/([0-9]+)$ image.php?id=$1 [L]
RewriteRule ^images/(.*)$ image.php?filename=$1 [L]

This allows either: http://localhost/images/5 or
http://localhost/images/myimage.png to work. I prefer the filename as it
looks cleaner and appears to be more standard. So, in a webpage, I can
now add the following html code to show the image.

Re: [PHP] image files - upload and managment

Hi People,

I am writing a web app on LAMP.
The app is sort of yellow pages where people can login and post
advertisments with pictures.

App needs to allow users to upload pictures. (jpg and gif),
needs to create thumbnails of those pictures
and to store thumbnails and full pictures.

App needs to manage all those files - can be as much as 20K plus
images.

I think image file size, file type and image dimensions restrictions
should be easy to handle by using $_FILES array and getimagesize
function.

The issues that I am thinking of and need suggestions about are

1) Storage and retrieval - File system sounds like a better choice
over database. We are talking about 20 thousand plus pictures.

I would do it in the database (PostgreSQL in my case). The speed isn't
going to be much slower if you keep things optimized. You can even cache
your images if necessary on the filesystem (for high traffic images).

2) Thumbnails - Should I create those once and save it in a file when
the image is uploaded for the first time. Looks like a faster option
than creating them every time on the fly.

I just recently finished working on a project where I knew that would
automatically create a thumbnail version of each image on upload... but
then I realized that I might one day want to change the default
thumbnail sizes.. so what I did was have it create a thumbnail on the
fly from the database. (this way I can control the thumbnail size in the
future). The speed difference was hardly noticed. I have done what I
mentioned above and am now caching images that get loaded frequently.

3) Security issues - I believe I must have a world writable 666
permissions directory to keep images as users of the web app are
uploading them. Does that create any security holes in my application?

The database will help you add a nice layer of security.

4) Any thing else related to image uploads that one might need to take
care of. Are there any tutorials on image upload issues.

an example:
http://blog.planetargon.com/index.php?/archives/26_Uploading_images_into_PostgreSQL.html

and here is how you can display the images from the db. I am also using
mod_rewrite so that it looks like it's coming from the filesystem, for
example:

mydomain.com/images/mypic.jpg actually
calls ./image.php?filename=mypic.jpg

 I have difficulty believing retrieving an image from a database will
 have similar speed performance as simply grabbing it from the
 filesystem... and if you're seeing a need to cache images on the
 filesystem anyways, that's certainly already an argument against it.
 

I tend to stick as much in the database with strict restraints. I know
that in my database, an image cannot be deleted unless several rules are
met. In the filesystem, a number of things could accidently delete the
wrong file. I treat my images as another piece of data and that data is
kept there by constraints.  

   2) Thumbnails - Should I create those once and save it in a file when
   the image is uploaded for the first time. Looks like a faster option
   than creating them every time on the fly.

  future). The speed difference was hardly noticed. I have done what I

 Thumbnailing on the fly may have decent performance, but it *is* slower
 than simply serving up an image. If you doubt that, try surfing from a
 T1 connection some time (dial-up users may not notice the extra time
 required to generate the image, but those on broadband will). In
 addition, if you generate a thumbnail every time the image is requested,
 you're making your server do extra work -- even if you're caching
 oft-requested images.
 
 I understand the argument regarding a future change in thumbnail sizes.
 However, generating thumbnails on a filesystem of images is something
 that is easily scripted and can be performed on an as-needed basis.
 (ImageMagick is great for this sort of thing, and scripts in PHP using
 GD could also be used.)
 

As I can do when I want it to be a thumbnail. Infact, in PostgreSQL, I
can use plPHP, plPerl, psycopg, etc and perform these tasks within
database functions. This isn't an issue at all. 

Here are a few reasons why storing in the DB can be more useful. 

http://www.oracle.com/technology/products/intermedia/htdocs/why_images_in_database.html

Also, Gallery 2, is moving to a database backend, one would wonder why
that would be a good move, considering the sole purpose of gallery is to
display images.

Yeah, don't make errors in your code. ;-)

Also, try to seperate your html and php code as much as possible. Use a
template system of some form. (ie. smarty)

Use a PHP editor with syntax highlighting..click on one curly brace and
then find where the other highlighted brace is and make sure that it
where it should end.

Learn how to debug your code. See how far it's getting for each
thing..add test messages and die() in different scopes of code.

Good luck,

 Seems pretty impossible since both Postgres and MySQL are stand-alone
 databases and have nothing to do with each other.

I am curious too. I have never seen any conflicts of the sort.

Rebuild it in PHP?

You can try asp2php...but don't expect much out of it.

 I am not so good in this: you want to say that SSL use 443 port

There you go, the standard SSL port is 443. If you want to verify that
you are on 443, then you can use SERVER_PORT

 I remember from back in my MS-DOS days the very good Clipper compiler for
 the dBase III language.  dBase III, not unlike PHP, was an interpretive
 language, and along the way some bright folks figured out how to write a
 true dBase language compiler, which then allowed for all sorts of nice
 things to happen.  One of the nicest things for me was that the compiler
 caught all sorts of little things before the same code in the interpreter
 would find them at run-time.
 

I believe that there are some commercial products that can do this for
you.

Not sure where you learned how to handle form posts, but you might want
to spend some time reading the PHP site, specifically looking at how
global variables work.

Try changing $view to $_POST['view'];

$myarray = array(1,2,3,4);

You can set an environment variable for your project like so:

just find the proper GMT time zone format..
