Re: [PHP] Re: PHP textbook suggestions?
You're missing the point-- it's not that there is a practical
difference in the examples, it's that there IS a difference, the
students see it, and it is an extra point of confusion that isn't
needed if one is being consistent.
I completely recognize that the practical effects of the differences
are small, but the learning effects of the inconsistencies is much
larger, particularly with a group of students that are not techies,
not geeks, not computer science or IT students...

Oh sure, there is some number of nanoseconds difference in evaluation
time, but that's meaningless as it is an insignificant amount of time
(and takes millions and millions of iterations to make any
perceivable difference).
Use whichever you want. For me, I use mostly, and usually only use
' when I am enclosing 's to save myself having to escape them.

perfectly valid and, in fact, I would argue the latter is better as
it is clearer, cleaner, and shorter.

Both are perfectly fine. I'd use the latter myself as I tend to
reserve the single quotes for enclosing strings containing double
quotes, but that's just my preference. I certainly wouldn't deign to
argue that my way was 'correct'.

Re: [PHP] PHP textbook suggestions?
I'd still like some actual recommendations for a good book for beginners. I think this discussion is getting a little ridiculous... I have my preferences for a textbook based on 5 years of experience in teaching this class. Of course I teach my students about superfluous parentheses as in: print (me); And the difference in quoting styles... But these are COMPLETE beginners, even beyond beginners, many having never even really thought about programming. I am lucky if 1/2 of them have basic HTML. So they get easily confused by differences in sample code... sure they learn, eventually, to deal with that, but if I can avoid making it harder on them I will. I prefer not having variables in double quotes for the most part-- syntax highlighters do a better job, and in the confusing (especially for a beginners) jumble of quoted HTML attributes and PHP syntax, etc... it is easier to spot and see the variables. And it reinforces the difference between displaying a variable and its contents. All that being said, I've yet to see two books that are consistent with one another, much less with me, so I said it was a PREFERENCE. All of your argument has resulted in-- as far as I can tell-- one anti-recommendation. So if anyone has any productive ideas for a good textbook for beginners, my ears are open. c -- Chris Lott -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] PHP textbook suggestions?
I see a couple of recommendations for textbooks now... thanks. As to why I think one style is good or bad-- probably the same reasons any of you prefer yours + in my experience, the style that I have adopted is the easiest for the beginners to understand and not be confused by. This list (naturally) underestimates how hard it is for non-techie, non naturally tech-inclined newbies to approach language syntax. The quotation thing is a good example-- they are taught about interpolation and trying to learn about quotation marks and escaping and when each is appropriate, then they are shown code like: echo substr(abcdef, 1); So they naturally want to know-- why the double quotes? And there's no good logical reason for double quotes in the example-- and there are languages where the function could take a variable to be interpolated that DOES need double quotes-- so it is very confusing to them. If I CAN, I would like to avoid that confusion so *I* Can teach them about the differences. Similarly my preference and teaching that they keep variables out of quotes-- it's a style thing, something I consider good practice, something I see most code examples I find use, so if I could find a text that did it, that would be great. For that matter, even a text that didn't do it but was CONSISTENT. It's amazing how many books are totally inconsistent. These students aren't at a level where inconsistency is the best approach to stimulating their learning. They get there, but it takes a while. c -- Chris Lott -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP textbook suggestions?
Looking for suggestions for a PHP textbook for an Intro to Web
Programming class that will be using PHP5 and MySQL. This is a
first-semester course, so no programming experience required.
It would be nice to have a text that adhered to (what I see as) good
practice using quotation marks... i.e.
print 'The cost is ' . $cost;
NOT
print The cost is $cost;
AND CERTAINLY NOT
print (The cost is $cost);
echo substr('abcdef', 1);
NOT
echo substr(abcdef, 1);
I will be teaching, so a book that a student can-- before the class--
work through and understand is good-- doesn't have to be a traditional
textbook! But it shouldn't be a reference manual either.

Re: [PHP] Dynamic Array Index using Variable
What I have is a form with 45 data fields... if any of a selected 35
of those fields is empty, I want to have the user go back. So I can't
loop over the entire _POST array. So I thought I would put the names
of the fields I *do* want to check into an array and check.
So this won't work:
foreach($array as $key=$value){
if(empty($value)){
$err_msg= $key is empty;
break;
Because the array is the names of the fields, and I want to check each
variable in _POST that matches. So instead of writing
if (empty($_POST['forma'])
if (empty($_POST['formb'])
etc
I would do something like
$fieldstocheck = array('forma', 'formb');
foreach ($fields as $thisfield) {
if (empty($_POST[$thisfield])) {
set the error flag;
}
But that doesn't seem to work.
Eventually I will use the array to associate error text:
$fieldstocheck = array('forma' = 'You must enter field A', 'formb' =
''Field B is your age in years and is required');
etc

Re: [PHP] Where to learn about these topics
In MySQL I would say... If you have data which has to be inserted in
serveral tables, you must first check if all conditions are ok. So, do some
selects to check if everythin in your database is ok, and after that,
execute the query. But, when you really want to make complex database driven
applications, choose PostgreSQL! This database is better build for
complexity (and not only that ;) ), and supports transactions and
references, and more stuff like that which can be really helpful to you...
And when you compare MySQL against PostgreSQL... PostgreSQL is a heavy
system compared with MySQL, also free, but when you look at the
functionality: SUPERIOR
But even with Postgresql I have the same situation. Let's say a user
wants to enter a new contact into the database. This contact lives in
a new city and has a new kind of relationship. To make that city and
relationship available, I need them in the related tables. Or I need
my form action to check for each one, insert if they are not there,
and then finally insert the new record. This last seems preferable
(one form), but no books seem to deal with the real world, only the
simplest, single-table cases...
$query = SELECT * FROM table1, table2 WHERE table1.id = table2.id AND
table1.value = 'value' OR table2.value = '' ORDER BY table1.name ;
is less readable than:
$query = SELECT * FROM table1, table2
WHERE table1.id = table2.id
AND table1.value = 'value'
OR table.value = ''
ORDER BY table1.name ;
Right-- but my question isn't about the query, but about the results.
Again, look at my result set:
+-+--+--+---+---+
| first | last | relation | city | state |
+-+--+--+---+---+
| Chris | Beks | business | Fairbanks | AK|
| Robert | Hannon | friend | Fairbanks | AK|
| Cindy | Lott | family | Fresno| CA|
| Derryl | Hartz| business | Seattle | WA|
| Kirsten | O'Malley | friend | Seattle | WA|
+-+--+--+---+---+
I want an output routine that does this:
CITY
person
person
CITY
person
CITY
person
There has to be a more elegant way than making a new query for each
city-- which is what the query I mentioned above fixes... but is the
kind of code I have put, with its ugly indexes and counters really the
best way? This is another area where books always stop at the simplest
cases...
$currentcity = '';
$counter = 1;
while ($thisrow = mysql_fetch_array($result))
{
if ($currentcity $thisrow['city'])
{
if ($counter 1)
{
echo '/blockquote';
}
echo 'h1' . $thisrow['city'] . '/h1';
echo 'blockquote';
$currentcity = $thisrow['city'];
}
echo $thisrow['first'] . ' ' . $thisrow['last'] . 'br /';

[PHP] Where to learn about these topics
Where can I learn topics such as:
1) Examples of complex PHP applications entering data into complex
related table structures. For instance, if I am writing an application
to create a class catalog that has 5 related tables, how do I handle
the workflow when the data in related tables doesn't yet exist? Do I
force a user to enter data into 5 different forms first? Do I have a
place to enter the new data on the main form? Do I create temporary
records as part of a step-by-step process?
2) Complex display with database results-- particularly when working
with many joined tables, displaying results effectively for reporting
(show me all departments, within that all classes, within that who is
teaching, sorted by department). The queries aren't hard, but if
optimized into one big query the constructs for displaying seem to get
ugly. For instance, given a query that gives me these results as
$result (joined together from three tables):
+-+--+--+---+---+
| first | last | relation | city | state |
+-+--+--+---+---+
| Chris | Beks | business | Fairbanks | AK|
| Robert | Hannon | friend | Fairbanks | AK|
| Cindy | Lott | family | Fresno| CA|
| Derryl | Hartz| business | Seattle | WA|
| Kirsten | O'Malley | friend | Seattle | WA|
+-+--+--+---+---+
It seems like there must be a more efficient way to get a listing of
each city and who lives there than:
$currentcity = '';
$counter = 1;
while ($thisrow = mysql_fetch_array($result))
{
if ($currentcity $thisrow['city'])
{
if ($counter 1)
{
echo '/blockquote';
}
echo 'h1' . $thisrow['city'] . '/h1';
echo 'blockquote';
$currentcity = $thisrow['city'];
}
echo $thisrow['first'] . ' ' . $thisrow['last'] . 'br /';
$counter++;
}
Although this is preferable to running separate queries:
$query = 'select lid, city, state from locations order by city, state';
$result = mysql_query($query) or die('Couldn\'t perform the query: ' . $query);
while ($thisrow = mysql_fetch_array($result))
{
echo 'h1' . $thisrow['city'] . ', ' . $thisrow['state'] . '/h1';
echo 'blockquote';
$pquery = select first, last from people where lid =
{$thisrow['lid']} order by last, first;
$presult = mysql_query($pquery) or die('Couldn\'t perform the query:
' . $query);
while ($prow = mysql_fetch_array($presult))
{
echo $prow['first'] . ' ' . $prow['last'] . 'br /';
}
echo '/blockquote';
}

You can also do this via a PHP script, which is what I do. I have 5 URLs all going to the same site (500 megs disk space). I parse the subdomain, and re-driect to the appropriate sub-directory. So do you have this code running on every page or does it only redirect from the index page or ?? c -- Chris Lott http://www.chrislott.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] zend studio 2.0
I hope we aren't going to get another chest-pounding real coders type of argument going here. Homesite *IS* a text editor. It provides an amazing number of shortcuts to tasks, including mouse-based tasks, many of which I guarantee you I can get done faster with a mouse than anyone can typing. It also offers a lot of pseudo-time-saving features as well, for which one would be better of learning to do it manually. But it isn't a GUI in any real sense as, say, Dreamweaver is. TextPad is at least as much of a GUI as Homesite in that respect. I use both of these great tools a lot... none of them are the stigmata of the under-developed programmer. People should use what they want, but don't dump on everyone who realizes that clicking a button or using a keyboard shortcut in something like Homesite or Textpad to create common HTML structures or PHP control structures is always going to be faster than typing them out by hand, no matter how craven a Notepad warrior one might be. Zend looks pretty good in terms of providing what I like in a development environment, particularly real debugging... unfortunately it was definitely not particularly stable when I last tried it in late December. Integrated debugging, syntax coloring, function reference, keyboard shortcuts-- these are all useful tools. TextPad has good PHP dictionaries, Homesite handles PHP well. Homesite is STILL the only editor I have found that enables an easy preview through the server mapping so that I can, with one touch toggle between my editing and the live code through my local development server, something that saves a lot of time vs jockeying between windows with other tools. Not all mouse use is just waving one's hands through the air, none of the programs mentioned are particularly mouse-centric. c -- Chris Lott http://www.chrislott.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] zend studio 2.0
Well, as you said, no point in arguing. Just that I think if someone really wants to develop they should learn some better tools than a GUI but it's a question of balance. I think a definition of GUI might be in order. Homesite, for instance, is just a big text editor. It has almost no GUI design features, drag and drop coding, that kind of thing. I think of a GUI as Dreamweaver, or something where you are not using the code directly. Homesite and the Zend Studio are both code editors that provide the same kind of features as TextPad with PHP libraries, clip books and syntax coloring files. Emacs, which I use a lot, is in the same class (not GUI, I don't think). I agree that with GUIs, by my definition at least, one should learn on tools in which they are really working with the code. If they can insert the skeleton of a control structure with one click or not doesn't impact their development (either of themselves or their program) negatively. c -- Chris Lott http://www.chrislott.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Books on PHP
I am new to PHP and was wondering if anyone can point me the right direction with PHP urls and books In the past few months I have received nearly all of the PHP books that have been written (I wanted to evaluate possible books for some classes) and I think all of the entry-level/beginner/learn the language kind of books. PHP and MySQL Web Development is a great book, and provides a good resource for both PHP and MySQL in one text. However, I think its sections on actually learning PHP are a bit on the short side, assuming more knowledge and self-motivation than a lot of people (ok, beginning students) might have. I highly recommend it, but I would add to it the PHP Bible (which you already have) and, if that isn't enough, the PHP books from Wrox. PHP4: A Beginner's Guide is actually pretty good and might have been (had I received it in time) the best choice for a class text, since it is structured and written that way. You really can't go wrong with any of those books, a good project to keep yourself interested, and a local copy of the documentation. c -- Chris Lott http://www.chrislott.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Mysql / PostgreSQL with PHP
Both work well with PHP. Later versions of PostgreSQL are quite fast (comparable to PHP). MySQL is still a little faster and there seems to be a much larger base of users and support. You can't go wrong with either one... if you need the features that PostgreSQL offers that MySQL currently lacks (stored procedures and subselects, which I am waiting for in the new MySQL almost with tears in my eyes :), I would go with pg.

RE: [PHP] Re: PHP in the University and Corporation [was RE: [PHP] Computer Science and PHP]
I agree about going to technical colleges and other areas. In fact, I made that very point. There is no reason that these kinds of programs even NEED to be four year degrees. I don't want to get into a debate about certifications. As one who hires programmers, I can say this for myself and many others: certification mreans squat to myself and to most people I know. They have become as devalued as Argentinian currency :) On the other hand, the general truth is that certification WILL open doors in some places, particularly those that are technologically clueless in the first place. They may or may not be jobs worth having, it may or may not happen for the job you are pursuing now or the job you might pursue in the future. My real point in all of this is that establishing a LAMP certification, for instance, or a PHP certification, is no panacea and is no guarantee of opening any doors, not to mention the possibility of such certifications becoming a joke as MCSE and other Microsoft Certs (for instance, and a cert I can speak of with firsthand experience :) have become in many circles and actually having as much negative impact as positive. c -- Chris Lott http://www.chrislott.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] PHP in the University and Corporation [was RE: [PHP] Computer Science and PHP]
Computer science is considered an engineering discipline in most institutions. And I think that's good... we need people out there to develop OS's, create database servers, etc. PHP can be effectively used in this curriculum, but C seems a lot more to the point. The place where PHP could (and should) make inroads is in the web development curriculum that is generally split off from the formal computer science programs. I think that split is a good thing even if it is made for the wrong reasons... and while one can quibble about real programmers and such, these programs that encompass web design, web mastering, systems admin and networking are the real ground for advancing PHP. Many institutions, like the one I teach for, are entrenched in ASP and Java because that is understood by administrators as a good thing to do and because it is often easier to find instructors with these skills (or at least the certifications). But there are inroads being made. I have typically taught web design, internet and networking. Now I finally am getting a chance to teach a PHP/MySQL class as part of the web development curriculum (finally as in we finally found good instructors to take the other courses so that I would have time). Also, these programs are typically staffed by a cadre of aduncts. If you have PHP skills and teaching skills and you can basically donate your time for the peanuts that are offered (and the fun of it), there is a place for YOU to help promote PHP. Someone else remarked that certifications would advance PHP. There is something to that, particularly in the corporate marketplace to USE it. More often, in my experience, PHP is slow to be adopted in the corporate environment because MS is so entrenched, and because MS' firm establishment on the desktop means hiring MS people, who naturally promote and hire other MS people, and administrators often equate using other technologies with abandoning their desktops. Certification has an equally negative aspect, though, unless stringently and particularly administered and granted, which would defeat the marketing ends. c -- Chris Lott http://www.chrislott.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
RE: [PHP] Re: getting a LAMP job in this economy
It's hard, I think in part, because of the reputation PHP is getting in some circles. Many of the people evangelizing it don't know anything else, and simply extoll all the 'wonderful' virtues of it. YES! This poisoning of the well has happened and continues to happen. The problem is that being an evangelist is a wonderful thing-- but you have to be quite skilled at communication to be a successful one :) Otherwise the person attempting to spread the gospel simply becomes looked at as an annoyance or, worse, becomes marginalized. I have dealt with a lot of folks in companies who have a negative view of PHP, MySQL, Linux, BSD, etc. simply because they have had their intelligence insulted, or been irritated, or been completely confused, or been preached to one too many times by well-meaning proponents of Open Source solutions who are either unable to communicate or simply victim to their own enthusiasm. There is probably nothing that doesn't have an Open Source solution in the abstract sense-- but in the real world of existing systems, personnel, and politics, the best solution may not be technically the fastest or even the most stable. The right tool for the job is my motto, and that might mean SQL Server, it might mean MySQL. It might mean a Linux server, it might mean Win2K.

[PHP] Setting title via included file
I have a page that includes a file in the middle, but I wish to set the
title of the page based on a variable set in the included file-- is this
possible?
PHP processes the page sequentially, so if I have $foo = Title in the
included file, it is too late to use it for the title of the main document.
I thought output buffering might be the key, but it doesn't seem to work.
Should it?
Basically, I was doing this for the output buffering:
***
function fixtitle($buffer) {
return (str_replace(XXX, $pagetitle, $buffer));
}
ob_start(fixtitle);
?
html
titleXXX/title
...
? include(file_that_sets_pagetitle.inc) ?
...
?php
ob_end_flush();
?

My idea is to have the authors insert a code/comment that indicates a page break in the text (something like, cryptically, PAGEBREAK) and then when pulling the article from the DB, create a menu for selecting pages (there has to be a small menu at the bottom of each article with a link to each article page and an indication where the user is), display the proper page, etc. I've still not got my head completely around how I am going to do this, so I am looking for suggestions on how other sites manage this need. c -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
