[PHP] PHP Application Structre
Greetings all, This question basically surrounds how you structure your PHP applications, whether it changes depending on what you're doing and which you'd favour. I have a feeling it'll come down to a question of personal taste, but on the off-chance there's a best practice I'll ask anyways. >From what I've seen and used, there seem to be three distinct ways of going about it. 1) Using a 'core' class which has a request handler in it. All pages in the site are accessed through that one page, e.g. http://www.somesite.com/index.php?page=ViewUser http://www.somesite.com/index.php?page=ViewProduct This is one that I've personally used most after becoming familiar with a bulletin board system several years ago. It means that pages are easily created as all the template/session/database handling is done by the central class. 2) Using SE friendly URL's like: http://www.somesite.com/products/22012/cool-game/ http://www.somesite.com/products/22013/other-game/ This approach seems to be becoming more common on the sites I frequent, however by accounts I've read it seems to be more intensive on apache as it requires a mod-rewrite function. 3) Using different PHP files for each page: http://www.somesite.com/viewproduct.php?product= http://www.somesite.com/viewuser.php?user=... This would appear to be the least developer friendly option? Hopefully someone can shed some insight into which is the recommended approach and why. I've been building bigger and bigger sites so having a solid foundation is becoming more and more important. Thanks for any help/feedback, I hope I've been clear. Alex.

Alex. = The second option doesn't really belong here, because you could go for option 1 or option 3, and then decide whether to hide your implementation behind a mod-rewrite. Option 2 would rather be part of a separate question "what is the cost/benefit of using mod-rewrite".

It would seem crazy to have all the logic needed for the blog and the cart being pulled in by PHP everytime you just needed to display a contact page. Far easier to keep everything a bit more modular. That way, if you need to update something, you update only a small part of the site rather than some huge core file. But, if your needs are even more simple, say it's just a very small brochure website you have, then running everything through a single index.php might not be such a bad idea.

This would limit your system to one type of OS though. For example, if you compiled it for 64-bit Windows, then you couldn't use it on a 32-bit server. Essentially you'd need to compile different versions for each architecture that you want to support. Would you compile it for Mac and Linux too (not forgetting the 32/64-bit issue there too) If a binary compile is what you're looking for then there was a thread a while back about the compiler that Facebook released which might be of some use?

Thanks, Ash http://www.ashleysheridan.co.uk == There are many approaches to this, and I think your final design will largely be determined by what you want to do, and your own skill and experience. If you want to initialise your application, check input and load all your base api functions before calling the specific script (function) to handle the query, then maybe you can consider using a single entry point for your application. It can simplify your design and maintenance, and there are ways to ensure that access to your scripts have been initialised via the single entry point. Careful design can allow you to add new modules/scripts/whatever without having to update your single entry point each time (look at some open-source apps for examples). It also allows you to move your entire application to some place outside the document root and leave only the entry script open to the public, which can add a bit of extra security to your application. Personally I use two entry-points, one for admin and one for everything else. Then besides graphics, flash and javascript, everything else is put someplace outside the document root. The reason I settled on that approach was because the admin script can handle all the slow heavy security-checking stuff and loading additional admin api's, while the general script can be small, fast and lightweight, but won't allow any access to the admin functions. Neither script needs to be updated when adding to or changing the main application. Cheers Arno

I've been building bigger and bigger sites so having a solid foundation is becoming more and more important. Thanks for any help/feedback, I hope I've been clear. Alex. Here is my take on your 3 options: 1] Basically the approach taken by so-called CMS systems like Joomla. Three major problems. One, everything is in one core and DB; so if there is a major bug, crash, hack, whatever, it is hell to repair. If the site is very active, backups can be a problem trying to recover anything that has changed since the last backup. Also, sometimes bugs and hacks can exist for a relatively long time before they manifest themselves. Finding when such first occurred and then backing up from there can be damn near impossible. Two, any changes to the core can have unforeseen consequences somewhere in the site. Three, if the core breaks the whole site is down. 2] I use essentially this approach. But, don't use mod_rewrite. It is an unnecessary complication. Remember in the PHP world the initial php page "owns" the session. So, the current working dir is where the php file is. I like the fact that all pages are called by a URL name e.g.; www.foo.com/bar/filex.php and I save the pages data in a sub directory or DB just for it. e.g., www.foo.com/bar/data/dataFile.db. All of my application types e.g., simple html pages, sign up registries, etc. each have their own config and functions file, etc. in a separate dir/ Each page can have a custom css, images, etc. in it's dir and for special situations, I can write a php that performs some special functions and then calls the common application script. If the page becomes obsolete, I simply delete the dir and subdir. When I update a application type core code, e.g., Signups, I don't need to worry about affecting regular html page types. Here is one of my typical "calling files "www.foo.com/Seminars/Running_Economy.php": Can't get any simpler. 3} Unless the site is small and has few pages and applications, it is almost impossible to maintain. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

As long as there are useful naming conventions for all of the files (I've seen projects where files have been named 1.php, 2.php, etc. I wanted to bloody kill the developer who thought that was a good idea!) It can be easier to maintain, especially when working in teams, where one person can work on one area of the site and another person can work on another. It makes sense sometimes to have different files for different sections of a website. For example, blog.php, gallery.php, cart.php could deal with the blog, gallery and shopping cart sections for an artists website. Yes, it could all be achieved with one script handling everything, but sometimes when the areas of the site differ greatly, it results in a lot of extra code to deal with pulling in the right template and content parts.

Several files is obviously a preferable method. How you structure the code is completely different though: do you allow a user to run blog.php directly or do you funnel everything through one file and then handle request dispatching through that.

[PHP] How to get input from socket client

I have not done any socket programs in PHP, but I have in Assembler, C and Perl. First, I don't think feof() will do what you think it does. I wouldn't expect it to show up until after the other end has actually closed the connection. The other problem has to do with thinking an fread() will always give you everything you sent in an fwrite(). TCP is a stream protocol, there are no guarantees about delivering a complete message in one read, or that two writes won't be read together. It only guarantees that all octets will eventually be delivered in the same order they were sent, or you will get an error. The buffering is completely hidden and outside of your control. If you want writes to be atomic, you want UDP, but then you lose the guarantee of delivery. If you want to enforce a structure on the data in that stream, it is your application's responsibility to reconstruct that data at the receiver. One other detail that may or may not make a difference. TCP actually defines two independent pipes, one in each direction. Many Unix applications create two processes to service a socket, one to send, the other to receive. Only occasionally does a protocol require alternating messages similar to a conversation or ping-pong match.

[PHP] PHP Image Host - Sending HTTP Headers Twice?
I have a php script which serves an image. It's very simple:
header('Content-Type: image/' . $ImageData['content_type']);
readfile($File);
When viewing the script with the Firefox Extension: LiveHTTPHeaders,
it gives the following output for a SINGLE request:

As you can see, the browser is requesting the image twice, and PHP is

Lots of people use templating systems and particularly Smarty. Here's
the difference between a templating system and just hand-coding:
Hand coding--
Templating system:
(Okay, I'm not familiar with Smarty syntax, but in essence template
systems allow you to type less when you want PHP values to show up on
the page.)
Advantage: It *may* be easier for non-programmers to "read" the page
with templating systems. I'm not sure this is really true. They're still
liable to say, "What the heck is {flavor}?" Besides, my inclination is
to tell designers to make everything look pretty, turn the resulting
HTML over the the coders, who will then mark it up for PHP. After that,
the designers can stay away from it.
Disadvantage: You're adding another layer (and a LOT of code) just to
save yourself some typing. With straight PHP, the server reads the code,
interprets the PHP, substitutes values and shoves the page down to the
browser. With a templating system, the system must load and call the
templating engine, which must then substitute the proper values, and
then output the built page to the browser.
Your choice.

I don't know how everyone else does things, but I get a feeling of being very
well organized when using smarty.
I have to say that by using smarty, it has also helped me understand PHP more
in depth. Maybe it's because of the strict organization, or maybe it's because
I've been practicing a whole lot more. dunno.

I get tired of correcting this incorrect assertion. Some templates
engines do what you describe. Not all. Some directly generate PHP source
code which is then either directly accessed via the web server or
directly included by another page. Generating PHP code from a template
engine can provide superior benefits over pure PHP since the distilling
of simple XML (or otherwise) tags can be rendered once via simple or
complex PHP processing during template compilation versus the same
processing being done on every page request. In fact some will produce
plain HTML that doesn't even require the PHP interpreter.

Rob.

Okay, you're clearly more familiar with templating systems than I am. My
impression of templating systems is that the templating engine scans the
raw page, makes substitutions, and then outputs the page to the browser,
all on the fly. You're saying this isn't always the case.
Are you saying that some templating systems simply generate output,
which may then at some later time, be requested by the browser? That is,
they would function somewhat like a combination of "make" and "m4" (a
macro processor)? So a programmer would code his page, then call the
templating engine, which would output the final page to disk, so it is
now available for download? Is that the distinction you're making?

Templating system:
(Okay, I'm not familiar with Smarty syntax, but in essence template
systems allow you to type less when you want PHP values to show up on
the page.)
Advantage: It *may* be easier for non-programmers to "read" the page
with templating systems. I'm not sure this is really true. They're still
liable to say, "What the heck is {flavor}?" Besides, my inclination is
to tell designers to make everything look pretty, turn the resulting
HTML over the the coders, who will then mark it up for PHP. After that,
the designers can stay away from it.
Disadvantage: You're adding another layer (and a LOT of code) just to
save yourself some typing. With straight PHP, the server reads the code,
interprets the PHP, substitutes values and shoves the page down to the
browser. With a templating system, the system must load and call the
templating engine, which must then substitute the proper values, and
then output the built page to the browser.
Your choice.
I get tired of correcting this incorrect assertion. Some templates
engines do what you describe. Not all. Some directly generate PHP source
code which is then either directly accessed via the web server or
directly included by another page. Generating PHP code from a template
engine can provide superior benefits over pure PHP since the distilling
of simple XML (or otherwise) tags can be rendered once via simple or
complex PHP processing during template compilation versus the same
processing being done on every page request. In fact some will produce
plain HTML that doesn't even require the PHP interpreter.
Okay, you're clearly more familiar with templating systems than I am. My
impression of templating systems is that the templating engine scans the
raw page, makes substitutions, and then outputs the page to the browser,
all on the fly. You're saying this isn't always the case.
Are you saying that some templating systems simply generate output,
which may then at some later time, be requested by the browser? That is,
they would function somewhat like a combination of "make" and "m4" (a
macro processor)? So a programmer would code his page, then call the
templating engine, which would output the final page to disk, so it is
now available for download? Is that the distinction you're making?
Yes :) Or some combination of this and what you described. Or this and
caching. It doesn't necessarily have to be built like an application
such as make would do. The application can lazy load the template
engine, compile the template(s) and then subsequently do an include() on
future requests. The compiled source code would run in the context of
the including function and so would be able to pull variables from this
context and so directly embedded PHP code could output these variables
as you suggest but without the template designed using explicit PHP
calls, or having to know about functions, or parameter order, etc.
Smarty is a push template engine. You push variables to the smarty
engine. You tell smarty to load the template. Smarty processes the
template by replacing tags or macros with the pushed values. Smarty is
also responsible for the caching so you kinda need to load the whole
bundle just to get the cached output. The type of template structure I'm
describing is a pull structure where the template pulls the data that
has been initialized via PHP code generated by the template engine.
