FWIW, I've been doing computers since before the CP/M days (pre-pre-DOS), so I do know the difference between absolute and relative paths. FWIW I've been doing computers for a long time also, and am well aware of CP/M. Based on what you said it didn't appear that you did know the difference, but I apologise for the mistake. I'm sure if you look at the URLs being requested by the browser it should be pretty clear that it's simply adding the paths you have in your HTML to the end of the existing URL. The fact that you didn't appear to have seen that informed my assumption. Well, the only way I know this is to look at the Apache logs. I was getting a lot of 3xx and 4xx errors (which don't show up directly in the browser), and looking at the requests, it appears that the browser is indeed dictating the place to find images, etc., based on the odd URL. I'm a little doubtful about the browser specifying things like the URLs for links within a HTML page. However, this would explain why there are separate entries for image fetches in the Apache logs, occurring after the main page has been requested. Do you have some reference for this? I'd like to read more about the server-client interaction in depth. I couldn't find any references so I wrote a quick overview of what the process is. Note that this is over-simplified but should get the basic process across. * Browser connects to the HTTP server on www.google.com and requests / * Server resolves / to a resource, commonly an HTML file, PHP script or whatever, processes it if necessary and sends the output back to the browser. * Browser receives the HTML content, parses it, builds a list of referenced URLs (images, scripts, stylesheets, etc) * Browser normalises each referenced URL according to a fairly simple set of rules... If the URL is not already in the form scheme://... If the URL does not start with a / // The URL is relative to the current location If current_url ends with / URL = current_url + URL Else URL = dirname(current_url) + '/' + URL Fi Else // The URL is absolute on the current domain // current_domain is everything needed to hit the same web server, so scheme://[[username]:passw...@]domain.com URL = current_domain + URL Fi Else // URL is already absolute, including the scheme, domain name, etc Fi * Browser then (usually) fires off a couple of threads to request the additional URLs, renders the page and executes any scripts it contains. The server has absolutely no involvement in resolving referenced URLs to complete URLs - this is all done by the browser. HTTP is stateless to the extreme, meaning that each request gets a single resource, even if they're done through the same connection. Hope that makes it clearer. Thanks for the summary. snip So specifying absolute links might be a bit much. I'm not happy with the way DW handles this stuff, but I have to strike a balance between my vim-handcoding-command-line method and my wife's click-and-drag-gotta-be-GUI method. We've covered this in the other thread. I can't speak for DW since I've only ever used it as a text editor, and even then only when forced, but I would be surprised if you couldn't tell it to generate absolute URLs. Something I do know is that you can set it up to automatically deploy to a separate virtual host on your development server, but based on the other thread you've already made a decision on how to solve your problem. I leave Dreamweaver issues to my wife. She maintains she can manually type in the link URLs, but that's really not a good ongoing paradigm. Now, if Dreamweaver had a config setting that said, Make all URLs absolute, I'd say that's the best resolution. Paul -- Paul M.

[PHP] Full versus relative URLs

One is to simply include the relative path to the file (relative to the doc root), like: /graphics/my_portrait.gif Or you can include the full URL, like: http://example.com/graphics/my_portrait.gif My casual observation seems to indicate that the former will load faster than the latter.

Check the framework's installation instructions to see if you configured mod_rewrite correctly for this to work properly. mod_rewrite isn't involved. Apache has a lookback feature that looks back through the URL until it finds an actual file it can execute, which in this case is index.php. Unfortunately, it appears that Apache believes the directory in which linked files are found is the *whole* URL. mod_rewrite might resolve this, but it isn't allowed on all servers.

If so please explain what you understand by what I'm saying and I can alter it to be more helpful. Here's the issue I have with this: normally I build pages on the fly with PHP. However, on this particular project, my wife is building the pages in Dreamweaver. And, as I mentioned before, while in development, the pages reside on an internal server, like this: http://pokey/example.com That is, pokey is an internal Debian machine where all our client sites reside as backups in the /var/www directory. So as far as pokey is concerned, the pages are at: /var/www/example.com but we see it as: http://pokey/example.com Dreamweaver has a very brain dead way of handling templates, resultant pages, and the internal page links. And while my wife is very savvy, her Windows-weenie-Dreamweaver way of handling links is to click on a button which opens a dialog box, in which she finds the image, and clicks Okay. This is all fine while the pages are on the development server. (Well, not really, since Dreamweaver regularly hacks up image links in non-intuitive ways.) But when they get uploaded to the production server on the internet, all those absolute links have to change from: http://pokey/example.com/graphics/myportrait.gif or /example.com/graphics/myportrait.gif to http://example.com/graphics/myportrait.gif or /graphics/myportrait.gif Moreover, I'm not even sure she can specify the links absolutely when doing her Click and Search routine. She'd probably have to manually type them in, unless there's some setting in Dreamweaver I don't know about. In any case, changing absolute links in development pages to absolute links in production pages would involve a heap of (dangerous) global search-and-replace magic. So specifying absolute links might be a bit much.

My advice would be to stop coding and sort this out as soon as possible. You think? ;-} If your development server has a different layout to your live server you're simply asking for trouble, especially since you're using a front controller pattern (as evidenced in another thread). Not so much. We've structured our backups and live servers this way for a number of years without incident. Paqes for clients are normally statically built in Dreamweaver, with possibly a modicum of PHP to handle forms. Internal company pages are built by me and reside only on internal servers. This is the first client project where we're using a front controller, etc. It's simple to fix this. Add a hosts entry for mysite.local pointing at pokey's IP. Change the server software so it has a virtual host for mysite.local pointed at the mysite.com directory in the existing web rooot. Which works up until the point where you go live with the site, and forget to revert the hosts file, so you can't get to the live site. And after you do revert the hosts file, you again have the same problem with the base URL for the production site being different from the development/backup site. Virtual hosting is beyond my Apache expertise, and again, would mask live sites we host. In addition, pokey's IP is not exactly fixed. It's served up by DHCP from an internal DHCP server. It's generally the same, but I wouldn't want to rely on that in a hosts file. This is not difficult and will allow you to solve both of the problems you are currently asking this list about. Actually, Ashley's base tag solution resolves the problem. However, I've moved on and dropped the front controller concept for this project. Instead, I'm opting for a snippet of PHP at the beginning of every static page built in DW which calls in the values necessary to populate the sidebars of the pages.

My personal opinion is that's where all programming is headed anyway, but that's just my opinion. With that said, what's the differences and advantages/disadvantages between C++ and PHP OOP? I don't know Java, but I suspect it's a more purely OO language than C++. I *have* coded in C++, and the OO aspects of C++ are like a bolt-on on the C language. There are some odd aspects of C++ because of its history as originally a preprocessor hack on top of C. PHP is *not* a good example for OO. There are a lot of OO principles it doesn't follow. I would have suggested Smalltalk, the original OO language, except that no one uses it any more, and other languages don't necessarily fully implement OO as done in Smalltalk. You're right about using a language which implements OO in a realistic way for today's programmers. I also agree you need a language in which to teach OO. Otherwise, this is all just theory, and won't stick with the students. Imagine learning algebra but never solving equations in the class. You'd forget the whole thing ten minutes after the class was over. In fact, it seems a little backward to teach OO programming as a lone subject. I would instead opt for teaching a language first, and OO as a secondary part of that course. Learning C++ will go a long way in assisting the student to learn Java, or vice versa. My experience programming C has been invaluable in coding under PHP. As a side note, I think students should learn a language like C before learning something like Perl, Python or PHP. Having to deal with defining/declaring variables and their storage methods before use I think makes for more conscientious programmers.

Since this session variable survives across page loads (assuming session_start() is appropriately called), how is it stored and recalled? Is it automatically stored as a cookie on the user's system? Or is it stored on the server? And how does a server get a cookie? Is it a separate request made by the server to the client? If the value I've asked the user for is *not* stored as a cookie, then is it passed as part of the HTTP submission or what? Thanks for any enlightenment on this. Paul -- Paul M.

Likewise, MSSQL is a proprietary product, and I doubt it has the performance characteristics you need. In case it wasn't clear, I would always opt for an Open Source solution before any proprietary one. The arguments are well known. MySQL is not an enterprise database. And its most useful database types are owned by a large corporation which isn't entirely friendly towards the Open Source movement. It's only recently that MySQL has acquired some of the characteristics of enterprise DBMSes. For the longest time, MySQL relied on the programmer to handle his/her own foreign keys and such. It is very fast, and very suitable for web databases. And it has widespread API support in other languages. PostgreSQL *is* an enterprise database. It was designed from the beginning by DBAs, not programmers as MySQL was. It is comparable in performance to Oracle and MySQL, though this depends on the types of queries you're doing. But it has full transactional support, foreign keys, insert appropriate DBMS marketroid terms here. And of course, it it not owned by a company and is fully Open Source. Feel free to flame me about this. I did a survey years ago before selecting PostgreSQL as our internal company DBMS. I've tracked the comparisons over the years, when PostgreSQL lagged in speed behind MySQL and seen PostgreSQL speed up. And I've seen MySQL add full-fledged DBMS features. So their capabilities have come closer and closer together. But I believe PostgreSQL is still the superior choice for an *enterprise* DBMS. Paul -- Paul M.

Re: [PHP] Preserving History
On Thu, Feb 05, 2009 at 04:38:25PM -0500, tedd wrote: Hi gang: To further the Garbage Collection thread on to another level (i.e., preserving history) please consider this: Okay, let's say we have a table containing all the instances of tutors teaching courses. A record might look like this: Course-to-Tutor table course_id = 123 tutor_id = 7 date_active = 2/4/9 date_inactive = null The above record was assembled from the following recrods: Tutor table: id = 7 name = joe Course table: id = 123 title = Introduction to Moonshine Okay, so let's now delete the course Introduction to Moonshine! At the first opportunity to search the Course-to-Tutor table we find that the course 123 is now absent from our database and as such we set the date_inactive field -- it won't be considered again. Okay, so what does that tell us about the history? It only provides that at one time joe taught an undefined course. Furthermore, if joe quits, then we only have a record that says someone with an id of 7 taught a course with an id of 123 -- that doesn't make much sense, does it? No. If you're concerned about history, leave the course and tutor records in place. Simply change record in the Course-to-Tutor table. Set the date_inactive field to today's date or whatever. If you're concerned about history, you never delete the records that contribute to a link table. You can delete the record that binds them together in the link table, but not if you want to preserve history. Now, if we reconsider the Course-to-Tutor table and instead of putting in the tutor_id and course_id, we put in the actual name of the tutor and title of the class, then at least we have a history that makes sense. Don't do this. Your searches and indexes will take longer and it will complicate things. Maintain your primary keys as integers. If you want to know the name of the guy who taught course ID 123 from this date to that date, just issue a query which joins the tables. As long as your data is somewhere in these tables (in *one* place, please), you can join tables in a query and get any info you want. However by doing that, we violate the primary principle of a relational database by creating redundant data. While this is true in the ideal world of Codd, in the real world, there is often some minor duplication of data. But in your case, it isn't needed. I guess that one can say that if we never actually delete the tutor nor the course, but instead just make them inactive as well, then we have solved the problem -- is that the answer? In any event, what problems do you foresee if I used the actual names and titles for the Course-to-Tutor table instead of their id's? After all, the instance records would retain a simple history of what happened regardless of deletions AND a search for Introduction to Moonshine should be essentially as fast as a search for 123 if both fields are indexed, am I right or wrong? Not necessarily. In fact, if you add on to this schema, you'll ultimately find that IDs are vastly easier to manage. They make the queries more complex, but the tables are easier to manage. Trust me on this. I've had to go back and redesign tables where I used a long string like a name for the index, and it's generally a bad idea. I expect most DBAs and programmers will agree. Oh, here's another *excellent* reason not to use names: fat fingers. If someone misspells a name or a course title, you can change it to your heart's content if it's just a field in a table. But if it's a key that binds tables together, you can't change it without cascading problems. That key is now in *at least* two places and must be changed *everywhere*, and the DBMS normally won't let you do that. You could add cascade update provisions into your tables, but why?

An array is like in math, except that an array in PHP stores anything

An object can also store a bunch of different things, but it also has
methods, which are really just functions. An array won't actually *do*
anything; you have to do things *to* it. An object can actually do stuff
at your direction. Like:

The object here is $kitchen, and you've told it to use its make_coffee()

In case this has yet to be answered to your satisfaction...
Your page will *have* to reload when the user presses the button, but
the majority of content can look the same, except for the content you
want to change.
Let's say you've named the button section and its value is home as
in:
input type=text name=section value=home/
When the user presses the button, the form now shows the value of
section as home. PHP knows this has occurred. So you can make any
action occur by simply (in PHP):
if ($_POST['section'] == 'home') {
do_something();
}
In your case, you want a section of your HTML page to display something
else. So, wherever you want that content to be displayed in your HTML
page, do this:
?php
if ($_POST['section'] == 'home') {
echo a bunch of text for home stuff;
}
?
The ?php thingie tells Apache to interpret the next part as PHP, and
the ? part tells Apache that the PHP part is over. If you're using
GET instead of POST for the form then change $_POST above to $_GET.
Every item in a form yields a POST or GET variable which PHP can read,
just as it did above.
There are alternate ways to do this, but the above is probably the
simplest for you.
I recommend Programming PHP an O'Reilly book as a reference for the
language.

knows virtually nothing about the context in which it's loading a page.
In other words, if you were on Page A and you go to Page B, the HTTP
protocol ensures that the server has *almost* no idea of what you did on
that page. There are some exceptions, two of which are GET and POST
variables. If you did something on a form in the page you came from,
then GET/POST variable will be visible to the server (and PHP) when you
get to the next page. If the method on your form is post, as in:
form action=index.php method=post
then it will see POST variable. If you used the GET method instead, it
will see GET variables.
So if you want to communicate something to the next page you go to, you
will need to do it using a GET variable. GET variables are visible in
the navigation bar above your browser, and POST variables aren't.
So let's assume you want content.php to show home stuff if the user
was in index.php and pressed the home button. Then for the link the
push, you can do this:
a href=content.php?section=homeHome/a
Note the ?section=home part on the end of the URL? That's a GET
variable named section and it contains the contents home. When you
construct the content.php page. Put in a variant section as I
explained in the last email, except make sure it tests for the GET
variable section, like:
if ($_GET['section'] == 'home') ...
If you've programmed in other languages, PHP is a little difficult to
grasp, just because it has to deal with the HTTP protocol, and you're
embedding PHP in HTML pages. Otherwise its syntax is almost completely
C-like.

A couple of thoughts. First precede all your mysql_* calls with the at
sign (@) to shut up the routines if they generate text. I had this
problem, and that was the answer.
Second, store your connection resource as a class variable, so you can
pass it around to the various routines. Actually, you're already doing
this, but I prefer to do so explicitly, as:
var $link;
at the top of the class.
I have a similar class for PostgreSQL. I also have routines like
update, which allow you to pass a table name and an associative array
of field values. Same thing for an insert routine.

Well you could always change it to this:

}
and use the output you got from the function whenever you like (print
it, make it a toast, cook it with bees etc).
But the question still remains: Is there a way to do this?
The only way to save this text off is to put it in a $_SESSION variable

you could also store it in a database.

I'd try to move to using the mysqli functions or class, which
you can still wrap in a custom object (I do this because
I like to minimize the interface to the bare, bare minimum ...

does you class need to be php4 compatible? I'd hope
not but you may still have to support php4 ... even then

I always write with PHP4 in mind. You never know. Besides, I can always
change the internal implementation, if it's a class.

yes that's very bad advice. using error suppression is bad for performance
and debugging, don't do it unless you really really have to (e.g. you
have some function that spits warnings even with display_errors set to Off)
display_errors should be set to Off in production, and errors/warnings
shouldn't
be suppressed, they should be logged.
handle errors gracefully ('or die()' is not graceful)
I don't know about performance. But every call to the query() method of
my class tests to see the results of the query. If it failed, I call the
proper function from PostgreSQL to fetch the error, and store it in the
class. The query function returns false, if there's an error. So the
user can test the return and then call a function to echo the stored
error.
Second, store your connection resource as a class variable, so you can
pass it around to the various routines. Actually, you're already doing

Yep.

I have a similar class for PostgreSQL. I also have routines like
update, which allow you to pass a table name and an associative array
of field values. Same thing for an insert routine.
if the postgres extension is anything like the firebird extension then
there may actually be a few calls which do require error suppression :-)
Probably. When I first started coding PHP/PostgreSQL, I was getting
stuff printed out from the pg_* routines on the webpages and screwing
things up. I was on the PostgreSQL list at the time, and sent an email
to the list about chatter from the pg_* routines. The solution was to
prefix them with @. Works great, but I *do* check for and capture error
text and such.

If you don't use default or predone handlers, you have to put all kinds

What do I gain by using a try/catch that I lose by using if/else or similar? you use them not for control flow, but for deferring exceptional application states, which you can then handle in a small number of places as opposed to scattering the error handling of unlikely events in all sorts of disparate places. there is an art to using them, they compliment 'traditional' error handling, and I agree they can hinder if used badly. I understand, but then it comes down to how you define an exceptional application state. If I build a date class that throws exceptions, it's very OO-y, but a waste of my programmer time. I could just as easily build an error checker into the class and use that to check for errors. Generally speaking, my next step is going to be to display the page again and tell the user to retype the date properly anyway. There are reasons to use setjmp and longjmp in C as well, but I only ever used them once, and later ripped out that code. Paul -- Paul M.

[PHP] Client/Server Printing
I'd like a side check on what I'm doing to print on our internal network. We have an internal server/site which uses PHP code I've written to run the business-- invoicing, A/P, inventory, etc. Some things, like invoices and reports, need to be printed. Now remember, the code is on the server, and we access it from our client machines on our desks. When we print, we do so to our local printers, attached to the client machines. So the best way I could think of to making printing work was to generate PDFs of whatever needs to be printed, dump the PDF on the server, and provide a link to the PDF on the web page. The user clicks on the generated PDF, and his/her browser opens up Acrobat or xpdf, and prints from that application to their local machine. Is that a reasonable way to implement this?

The only explanation I can see is that someone has somehow managed to cache or mirror the version 1 logic, and is still dutifully stuffing pornography into it. As it is my understanding that the PHP code which handles the processing is inaccessible to the user, I cannot understand how this could have been done. Does anyone have any suggestions? If Google can spider and read your site, why can't someone else? I've had similar things happen. Any program that uses the HTTP protocol to fetch your site will only get the page as rendered by the server-- sans PHP. But I can imagine someone else programming something to snag the page a different way-- *with* PHP. But actually, they don't even have to be that sophisticated. All they have to do is submit a message to your form the first time, note the variables and their characteristics, and then resubmit that same type of content later using the same variable names and characteristics. Here's something you might do: 1) Rename the page in question. That way their submission won't piggyback on your existing PHP code. 2) Change all the variable names in the file. Chances are, they're just submitting an HTTP request with the proper POST/GET variables so your page processes it as though it were being accessed live. But if they try to submit this same content to a form that goes nowhere, Apache will just give them a 404 error. Alternatively, if you change your variable names and they submit to your existing form, your PHP can simply ignore it. Also, you might try CAPTCHA (look it up). It tries to weed out human from non-human surfers. You've probably got a 'bot submitting to you, so this might help. The page has text boxes for the name and e-mail address, a text area for the message, and a submit button. When the user hits the submit button the original code evaluates all the inputs, and either re-issued the page if it didn't like them, or transmits the message, with the title Feedback from XXX website. If the message is transmitted successfully the user is then shown a Thank you for your feedback page. In version 1 of the modification if the message passed the initial test I then submitted it to a second test. If it failed this, I replaced the message with [Censored], and sent it to an alternative address, with the title Rubbish from XXX website but showed the same Thank you page. I did this just so that if I accidentally rejected something from someone I knew, I could email them and ask them to send the message again. After a few days I decided I didn't need to know anything about these bogus messages, so I developed version 2 of the modification. This is the same as version 1, except that it uses a different title and replacement message (even though they are no longer used), and simply discards the message, but again shows the normal Thank you page. With either modification there is nothing to tell the sender that their message has been rejected, and, as I never reply to such messages, no way for them to find out whether or not I actually received their message. Whenever I try to send myself a bad message nothing happens, so that version 2 appears to have been implemented. I do not get any uncensored messages of this type now, so the rejection algorithm is satisfactory, but I'm still getting one or two messages handled by version 1 each day. I cannot see how this could happen unless someone has somehow managed to trap the version 1 PHP code (or, just conceivably, my provider switches to a backup containing an old code at some stage in a maintenance cycle). I'm not an expert at the HTTP protocol, but here's what I expect is happening: Clearly, someone captured at least the form responses from a release 1 version of your website. So now they're sending an HTTP header with the various proper fields, along with POST content which conforms to your original form. They don't need any forms or actual code to do this. They have a bot which just sends the proper responses. It would be like if someone showed up on your website and filled out the form and pressed the submit button. In that case, the client sends a response to the server based on the user submission. The server, in accepting this response knows (virually) nothing about where it came from or what to do with it. It's just a client response. It decodes the header info and the POST fields, and decides from there how to handle it. Normally, this would be to present a new page acknowledging the input. The point is that all your server is getting is a header and some POST variables from some IP somewhere. You could check your server logs for the offending IP(s) if you could

(These guys didn't even bother to test HTML with a bunch of Javascript or complex CSS in it. Might PHP have been faster?) Is *coding* faster and more efficient with frameworks? Sure. Does the code execute as fast? No. If execution speed is your priority, then you either scrap the framework, resort to a caching solution (which some of the frameworks already have in place, but which the testers didn't test), or figure something else out (like C?). If execution speed isn't your priority, then you might look instead at a framework. Anyway, the survey is just a tool which lets you know about one of the trade-offs in web design. I doubt any other method of testing would skew the results all that much. Paul -- Paul M. Foster -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

These worked fine for some years, but some months ago someone started stuffing pornographic advertisements into them. A few weeks ago I got fed up with these messages, and devised a very simple filter to reject them (I won't explain how this works, because if I did the perpetrators could immediately change their technique to defeat it). If the content was acceptable I handled the message in the normal way, but otherwise I deleted the contents, and forwarded the message to a different address with the title rubbish from XXX website. This worked well, but then I decided I didn't need to know anything about this stuff at all, so I modified the logic so that if the message is unacceptable it is simply dumped, but the sender is still shown the normal Thank you for your feedback message. This way the sender cannot tell whether or not his message has actually been sent, and so he cannot experiment to try to break the filter. Now if I try to send myself bad messages they simply disappear without trace, as expected, but I am still getting one or two messages a day sent with the version 1 (censored) logic. I have changed the messages in my new version, and verified that the old messages do not appear anywhere on my hard disk, and that there is only the new version of the feedback procedure on my server. The only explanation I can see is that someone has somehow managed to cache or mirror the version 1 logic, and is still dutifully stuffing pornography into it. As it is my understanding that the PHP code which handles the processing is inaccessible to the user, I cannot understand how this could have been done. Does anyone have any suggestions? If Google can spider and read your site, why can't someone else? I've had similar things happen. Any program that uses the HTTP protocol to fetch your site will only get the page as rendered by the server-- sans PHP. But I can imagine someone else programming something to snag the page a different way-- *with* PHP. But actually, they don't even have to be that sophisticated. All they have to do is submit a message to your form the first time, note the variables and their characteristics, and then resubmit that same type of content later using the same variable names and characteristics. Here's something you might do: 1) Rename the page in question. That way their submission won't piggyback on your existing PHP code. 2) Change all the variable names in the file. Chances are, they're just submitting an HTTP request with the proper POST/GET variables so your page processes it as though it were being accessed live. But if they try to submit this same content to a form that goes nowhere, Apache will just give them a 404 error. Alternatively, if you change your variable names and they submit to your existing form, your PHP can simply ignore it. Also, you might try CAPTCHA (look it up). It tries to weed out human from non-human surfers. You've probably got a 'bot submitting to you, so this might help. Paul -- Paul M.

It's about the lightest weight platform out there. It doesn't get in your way too much, but gives you the benefits of using a framework. My beef with frameworks like this is that they have too much cruft. I checked one time and codeigniter (again, one of the *lightest* frameworks) open about 15 files before a byte gets written to the screen. There is a lot of stuff in there you don't need (benchmarking code, etc.). I'd hack that stuff out if I were using it for real. One of the things you'll have to get used to is the MVC way of doing things. When you first start writing PHP, you probably don't do things this way, but when you start using frameworks, you've got to starting thinking in terms of what the view will do, versus what the controller, versus what the model will do. It's just a change of viewpoint you have to get used to. In any case, I've used CodeIgniter and liked it. I just didn't like all the cruft in it. And their license is not a straight GPL-like license-- it requires attribution even on derivative projects and requires clear notice of any changes you make to their code.

Then if you want to hire other developers to work with you, you have to train them and let them ramp up on not only the framework but also your core project too! More wasted time. The pages are significantly slower than straight PHP by orders of magnitude: [1]http://paul-m-jones.com/?p=315 What a great link! I've never seen this kind of comparison before. HTML is 70% faster than straight PHP, and the frameworks (even codeigniter) deliver less than 20% of the performance of straight PHP. The basic problem with frameworks is they try to be one thing for all people. This carries a lot of baggage with it. There's a lot of crap you end up pulling in that you don't want/need. Plus if you want to deviate at all, you either have to roll your own, or sometimes you simply just can't. They seem attractive with all their plugins and stuff, but honestly, rarely do the plugins do EXACTLY what you want, the way you want. It might be as simple as trying to change the look/feel of a button or something and you'll find out that you can't -- so now you have this website that has this section that doesn't look like the rest of your site. And if you find a bug, you have to try to either fix it yourself and then keep those changes migrated into new updates, or submit it to the developer and hope they implement them (and trust me, you can submit to them and have them rejected for all sorts of lame reasons -- even though the work has been done and you're using it!) I advise against it. Just follow good practices and use thin wrappers and functions. Don't get all OO googlie eyed and try to over-engineer and over-OO the code. OO is great for some things (like a User class) but don't start making some OO page renderer or form builder. Don't fall into the DB Abstraction trap either -- just use a wrapper around your DB calls (see attached), so you can swap out that wrapper if (and you almost never do) you change the DB. Don't be suckered by something like QuickForms -- you WILL run into limitations that you can't get around and are at their mercy. Don't buy the hype that DIV's are the magic bullet and TABLEs are poor design -- Tables are still the best and most ubiquitous way to align things in a browser agnostic way (including mobile phones, etc.) and to layout forms. I agree and disagree. I agree there's waaay too much herd mentality in the programming field. (Fortunately, Linus Torvalds didn't listen to the academics who insisted that microkernels where THE WAY, or we wouldn't have Linux today.) OO is nifty for some things, but it's certainly not the fountain of reusability it was originally promoted to be. And I also agree about tables versus CSS. I can render a page very precisely with tables that would take me hours to get right with CSS. And I really don't give a crap about what experts say about anything. I find experts to be wrong much of the time. OTOH, I just finished writing about 80K lines of PHP/HTML, all by hand, no OO, no classes, no nothing. Each page in one file, except for a few helper functions in a couple of common files. I wouldn't want to go through that again. I've opted for a framework on rewriting this code, just to cut down on the number of lines of code I have to manually write. But I built my own framework, which doesn't call in 20 files for each page load. Very compact. Probably not suitable for every kind of project, but it works for this. Incidentally, I would differ from the reviewer in the link above only in this respect: He maintains that every line of code adds time. While this is true, I believe it's the number of files which have to be opened which drags down framework numbers the most. When I wrote C code, the CPU would blaze through the actual code, but file opens and reads consumed far more time than in-memory code execution. Paul -- Paul M.

As for HTML weenies, my experience has been the opposite. My company does websites, among other things. Most of my work involves our internal website, which runs the company. I do PHP and the HTML for the internal website. My wife does the design/HTML for customer websites. If a customer website needs PHP, I do it. I don't know how many times we've had to deal with outside web design types, and found their work to be atrocious. I also have a fair amount of contempt for people who refuse to learn anything outside their narrow field, which is what I see in a lot of HTML folks. I would have more respect for them if they took the time to understand at least something about PHP, and thus better understand what I have to deal with in their HTML. My wife doesn't know as much about HTML as I do, since she uses Dreamweaver to code HTML. But I code HTML by hand, and I don't have the patience to do fancy HTML the way she does. Consequently, the internal website is visually pleasing but not fancy. Customer websites are prettier than our internal one, but have almost no PHP in them. However, I've had many situations where my wife has designed a pretty page I have to now add PHP to. It's tricky. But as a consequence, I tend to code HTML without resorting to rendering classes.

One of the best things that ever happened to me (with regards to
writing PHP) was deciding not to embed it in HTML anymore.
I either:
a) generate the HTML from classes I've built (HTML, Forms, Tables,
Images, etc) or use an equivalent PEAR class
- or -
b) Use Smarty templates...in which I still generate the HTML that will
go to the template (where required) with the HTML generation classes.
The advantages are abundant.
I can't imagine having to maintain some of the code I saw in the
examples above. My favorite WTF was with this snippet:
$imgHTML = 'img src=' . $url . ' alt=' . $alt . ' title=' . $alt
. ' class=' . $imgclass . ' /';
Holy crap...REALLY!?
All that string concatenation and there's not even width/height
attributes in there!
That would look like:
$i = new Image('path/to/image/file');
$i-__set(array('class'=$imgClass, 'alt' = $altText));
$i-toHtml();
Being able to change every image tag in a site by editing the
class/method that created is just too big an advantage not to use. Not
to mention the auto-generated width/height attributes, the ability to
auto-produce thumbnails and fullsize images from a single file...
After struggling through the beginnings, I wrote classes to generate
basic HTML elements, then tables, then forms, then images.
It saved me a bunch of time and taught me to see the website as an
application...not as a web-page with pieces of data in it.
Somehow, coming to that bit of knowledge was very helpful to my life
as a programmer.
I've written a lot of code like the original example above, and still
do, but I see your point, since I've written code like yours too. I
write all my PHP code (and I write a *lot* of it) solo, with no help and
no collaborators. But as I understand it from a lot of framework types,
the ideal is to set up the HTML so that a HTML coder can understand
what's going on, without having a lot of PHP weirdness in it. Meaning,
if you're going to infuse your HTML with PHP, you should do it in a
minimalistic way. It'd be a helluva lot easier on me to do it all
through PHP classes, though.
I also come from a C background, and I recognize significant differences
between the paradigm for C programs and HTTP-based coding. Considering
that every PHP program paints generally a single page, I'm not a fan
of loading up 14 support files every time I load a page of HTML. That's
why I don't use one of the MVC frameworks available in the FOSS world.
CodeIgniter, which is one of the lightest weight frameworks, opens
something like 17 files before it paints a single byte in the browser.
The upshot is that I don't like to use a lot of libraries scattered in a
variety of files to render HTML/PHP pages.
But here's a question for those of you who work in a collaborative
environment-- are you really ever in a situation where some HTML weenie
is coding HTML pages and you're somewhere else doing the PHP work? Or is
that some academic's view of the way things *should* be done?

Yup.
By changing the suffix (extension), you are telling the server that
this file is to be treated differently than a html file. As such, the
php interpreter will process the file before it is sent to the
browser.
A statement like:
?php echo('Hello'); ?
Will print Hello to the browser. In fact, the browser will never
see your php code unless you make a mistake. The file will be
processed and delivered to the browser as html.
Please note that my use of echo above does not require the (), that's
a habit I practice for no good reason whatsoever other than I like
it. I think it's because I'm dyslectic and it makes sense to me.
In any event, I would consider the followingbad practice:
?php echo('h1Hello/h1'); ?
Whereas, the following I would consider good practice.
h1?php echo('Hello'); ?/h1
As best as you can, try to keep php and html separate.
I know that some have different ideas on good/bad practices, but
you'll develop your own views/habits as you grow and learn.
And let me present an alternative perspective. Never do something like:
?php echo 'Hellow world'; ?
Let Apache (or whatever) interpret HTML as HTML, and don't make it
interpret PHP code as HTML.
Instead, do:
h1Hello world/h1
If you're going to use PHP in the middle of a bunch of HTML, then only
use it where it's needed:
h1Hello ?php echo $name; ?/h1
The contents of the PHP $name variable can't be seen by the HTML, which
is why you need to enclose it in a little PHP island. Naturally, if
you're going to put PHP code in the middle of a HTML page, make the
extension PHP. Otherwise, Apache will not interpret the PHP code as PHP
(unless you do some messing with .htaccess or whatever). It's just
simplest to call a file something.php if it has PHP in it.

In essence, I have a 'front controller' class that builds the page to be displayed depending on several criteria. One issue I'm having is that when a user logs out of my application, I destroy the cookie that indicated the user was logged in during my preRender process, and then go onto display the 'logged out' page. Unfortunately, I have a page element that indicates whether the user is logged in or not, and I assume because the cookie destruction is being sent down in that page request, when that page renders it still appears as if the user is logged in, because the cookie still exists until after that page is rendered. So, I thought perhaps as part of my logout routine, I could set a variable that my 'are you logged in or out' code could check and use to override whether or not it displays the 'login' url or the 'logout' url. I thought that in that code I should be able to check the value of a public variable that is in my front controller class, but it appears I can't? So, pseudo chain of processing would be something like this: - call index.php - instantiate front loader class - perform pre-render processing, if logging out, set public variable in class to true - call actual page to be rendered via require_once - in page being rendered, call function from separate file that displays 'login / logout' url - in that function test public variable in front controller class to see if true - if true, regardless of whether or not the cookie still 'appears' to exist, display 'login' url because user has logged out However, am I right in thinking that the function that displays the login / logout url is actually unaware of the existence of the front controller class at the point at which it is being called? M is for Murray I'm not quite sure why you don't force the login/logout page to use the front controller. Here's how I do it: I set various variables, and check the login status (I use $_SESSION variables to hold user ID and encrypted password). If the user is not logged in, I force the controller to be the login controller, regardless of whatever page the user *wants* to display. Then I go ahead with instantiating the controller, in this case, the login controller. So essentially, if the user is logged in, I go ahead and instantiate whatever controller they specify. But if they're not logged in, I force the login controller to be the one which is instantiated. (In my case, the front controller isn't really a class as other controllers are. It's just a bunch of routines and function calls in index.php.) Does that make sense? Paul -- Paul M.

I'm storing ANSI escape sequences in an array, stored like this:
$connections[$channel][2] = $info['colour'];
$info['$colour'] would contain something like \033[33m
Now, my problem is when I try and print it:
$pstring = $connections[$channel][2] . $connections[$channel][1] . .
$buffer . chr(7);
It will print as a literal string, actually printing \033[33m to the
screen, so how do I make it work?
I'm sure I'm missing something fatally simple here.
Thanks for your help,
Luke Slater
What you're storing is human shorthand for bytes sent to the display.
(I'm assuming you're working with the terminal here, not a browser
window.) The \033 indicates an octal byte with that value. But when you
send it, you're sending each character individually to the screeen. That
is '\' is one byte, '0' is the next, '3' the next, etc. That '\033' (and
subsequent codes) need to be coded as single bytes and sent bytewise to
the terminal. And if your terminal isn't configured to accept ANSI
excape codes, it won't work anyway.
Your chr(7) is the clue. Your codes, if numeric, need to be converted to
integers and given to the chr() function, and output using that
function. Try converting some known codes into integers, outputting them
via the chr() function, and seeing if the result is what you expected.
You may need to use the inverse function, ord(), to get your codes into
numeric form. For example, ord('m') will return decimal 109. That's only
an example, since you should be able to send single characters to the
terminal as is.

[PHP] losing mysql connection during cron job
I've got a simple script running as a cron job that's getting
intermittent Lost connection to MySQL server during query errors.
The script sends out listserve messages, 50 BCCs each minute,
sleep()ing for 60 seconds between sends and updating a data table
after each send. The whole BCC list varies from one message to the
next, but messages typically take 10 or more sends in batches of 50 recipients.
Inconsistently, the script aborts with the lost connection error
after a varying number of sends. Rarely it bombs not at all and
performs all 10 or 12 updates without error.
The script cycle is, symbolically:
foreach (recipients as batch)
{
mail() using batch of recipients;
mysql_query() update table;
sleep(60);
}
final mysql_query() update table as complete;
In an attempt to cure the problem I'm re-establishing the $conn
before each query and doing a mysql_close() after each query, but the
error still occurs.
The hosting is Media Temple's gridserver. I've never encountered
this error in any of the many PHP/mysql scripts I run on Media Temple
accounts, but this is different as it's a cron job.
Can you suggest aspects of the process that might lead to this error
that I should look at more carefully? I can understand that sleep()
might lose the connection between PHP the MySQL server, but why
would the script be unable to reconnect after sleeping? Would that
be a server-dependent issue or is there something I can do in PHP to
nail down the connectivity?
I'm hoping to get assistance on this issue without having to clean up
the script enough to invite in guests, but I'll do so if required.
Thanks,
Paul

(but I want an error message!) xsd:element name=streetNumber minOccurs=1 maxOccurs=1 type=xsd:int Almost the same for this more advanced restriction, you can provide every string. There is no error message and the whole string is accepted by my server. xsd:simpleType name=Email xsd:restriction base=xsd:string xsd:pattern value=^[_a-z0-9-]+(\.[_a-z0-9-]+)[EMAIL PROTECTED](\.[a-z0-9-]+)*$ /xsd:pattern /xsd:restriction /xsd:simpleType I hope there are some people that have some more experience with PHP/SOAP and the use of restrictions who can help me with this!

If you need some real, local, help, mail me off list, and I will see about you guys paying me to do this for you (at SA prices) ;) Seriously though, you won't get what you want with GD... --Paul All Email originating from UWC is covered by disclaimer http://www.uwc.ac.za/portal/public/portal_services/disclaimer.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] strange behavior, when converting float to int

PHP Version 5.2.4. Is this not coming from the underlying C libs that directly use the FP on the CPU? I would say that the compile flags, CPU settings etc would probably have an impact on accuracy. --Paul All Email originating from UWC is covered by disclaimer http://www.uwc.ac.za/portal/public/portal_services/disclaimer.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

As the system which I am developing for my client uses Unix timestamp. There are probably multiple solutions. AFAIK time is a 32 bit signed int, making it unsigned would add like 100 years onto your app. This might effect my application in the future If your app survives that long! Why not just maintain it and when times change, your app changes? :) Seriously, this is really not a big deal! Thank you, in Advance.
