Those were to good old days. 680x0 was the nicest machine I ever met - especially nice when writing for OS-9/68000. Yup, them was the daze... My perspective: scripting can be "programming light" (or lite, if you're illiterate and/or in marketing), but can just as easily be serious programming. This is especially so, now that many scripting languages support OO to some degree. Equally, I've seen some C code that I'd be somewhat reticent to call "programming". Programming isn't all about stacks of procedural code either; consider declarative programming. (Yes, Ash, XHTML and CSS are effectively a form of declarative programming!) http://en.wikipedia.org/wiki/Declarative_programming The trick with languages is to: * pick the one (or more) appropriate for the task * pick the design approach appropriate to the language (and other tools) To be a decent web developer, with database-driven pages, one often has to manage a design that spans multiple languages and sometimes more than one programming paradigm. Consider a simple HTML input form sending information to a database: * (X)HTML for the page, including the input form * CSS for managing layout and styling, even active menus etc. * maybe some JavaScript for smart validation or field management * server-side programming for accepting the form post * maybe some database programming (SQL) for updating the database Compound that with some mostly-declarative XSLT, Flash, Java, .htaccess etc. and you've got a relatively complicated toolset that traditional programmers scratch their heads over when initially making the switch from their one-language development environment.

This is not good because you are calling count every loop iteration.

Sure, it's a mark-up language but if you don't program it right, it will screw up -- it's just more forgiving than most.

If you think either of those two are not languages, then I think you're underestimating their power. I think the division between what is/isn't a computer language is somewhat blurred today as compared as to what it used to be. I remember we had the types who said that if you weren't programming on a mainframe, then you weren't programming. Others said if it's not compiled, then it's not a real application either. Both statement were equally lame. There has always been (probably always will be) those who want to separate people into different camps based upon their opinion -- but so what? Who cares? I don't. Over the years, I've had an assortment of clients who knew nothing about computer languages, but insisted on a specific language because of their limited understanding. I even had one client where I provided the end application that did everything he wanted, but he refused to consider it because if was written in a language that his friends thought too basic. Yes it was BASIC, but it worked better than the C++ crap that his programmers eventually developed two years later. My position -- give me a problem and get out of my way while I solve it.

indeed but beware, using a variable named $value after such a foreach loop

E_FATAL means the engine is in an unrecoverable state - they can't be handled in the php code by their very definition, whether this is strictly true in this case I don't know. E_RECOVERABLE_ERROR was introduced long after it was decided E_FATAL must/should be used in the described scenario. if you really think the behaviour could be changed without breaking BC by all means submit a patch ... if it's good and the argumentation sound the core devs may accept it, otherwise change your code to work with the implementation that exists rather than complain that php is not like . no? > > Best regards > > Christopher > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Close. It actually looks like this:

This makes sense because for each iteration of the loop, PHP places a

you are specifying with this code that you want it to place a reference

While you teacher technically is wrong, you probably could implement

best to just use a foreach loop. foreach was designed specifically as an

Only thing to note with the foreach is that you are actually working on
a copy of the array, so if you intend to modify it, pass it by reference.

Programming, scripting, coding--whatever you want to call it. They all involve similar methods. I made a program in VB.NET that takes a text file list of phone numbers and creates a geocoded XML tree by state, areacode, prefix, and finally extension. I compiled it into an executable. That was programming, yes? I then took that exact same code (the only part that changed was the output--it streams as an XML attachment instead of creating the output file on the local file system), and created an ASP.NET web site out of it.

If you used eval in the above statement (yes, you did) then you answered

Currently in college seeking a Computer Information Systems degree (Bachelor of Science). I will then continue into the Masters' program. I've taken courses on Database Systems, Decision Support Systems and Warehouse Management, Programming and Algorithms, Advanced Algorithms, Assembly Language (Motorola 68000), Operating Systems (Win32/POSIX), Systems Analysis, and Software Engineering (I'm sure I'm missing a couple from early college and high school... Pascal, VB, etc., but whatev). When I get my first degree, I will have added Artificial Intelligence, Systems Design, and Distributed Computing to that list. However--I have not been taught one lick of PHP in college. Then again, I think the language has very little to do with the program's power; it's mostly up to the programmer and his/her methods.

Oh... duh! :) You know what they say, if you're going to say something,
say it all in one place, not part of something in one place, and the
rest later on. Not everyone reads to the end you insensitive clod ;)

I saw a relative bug that suggested this so the only thing that I should
do was:

'xxx', array(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY=>true));

sounds like a poor teacher, however I have a feeling he simply wants you
to be able to count the items in an array without using the count()
function. In this case you would be best to use a foreach loop.
you are correct in saying that a while($myarray) loop would be infinite,
unless you use a function to reduce the array on each iteration of the
while loop as such:

just for fun:
$a = range(1,10);
for ($i = 0, $c = count($a); $i < $c; print($a[$i]."\n"), $i++);
... gives an idea of the power and flexibility of a for loop
constructor, i.e. you can pretty much write a complete program

Re: [PHP] while question
Hi,
i'm on PHP training and our lector is telling us that to avoid counting an
array item amout thanks count($my_array), he tells we can do:
while($my_array)
{
... do something
}
but from experience this is an infinity loop...
it should be always something like
$count = count($my_array);
while($i <= $count)
{
...
do something
...
$i++;
}
has someone already use such syntax ? i mean as the first one.
thx.
Probably the easiest way for doing this is using foreach:
$a = array(1,2,3,4,5);
foreach ($a as $i) {
print $i."";
}
This outputs:
1
2
3
4
5
This for e.g. gives an infinite loop:
$a = array(1,2,3,4,5);
while ($a) {
print $i."";
$i++;
}
So you are right because $a will always evaluate as true since it not
empty. For these kinds of questions you should read the manual first and
then ask here.

The while would work if you removed elements of $my_array inside the
loop, but you would still need to be sure that it would eventually be
empty.
I would guess that your lecturers point is that you shouldn't call
count on every iteration as it's a waste of time. He may also be
confusing while for foreach in which case I'd leave because you're
unlikely to learn anything from him.

I disagree. this kind of thing belongs on php-general (and lets keep it on list
please), if you have a serious proposal/rfc and/or one develops from a
discussion
there then likely some of the old-hats will likely recommend escalating to
internals.

fine, so your not an OO noob. nonetheless your going have to get accustomed
and intimate with php's implementation which is what it is, it works, it's
consistent
but may not conform to all your expectations that you bring with you from other
languages ... it's a question of you adapting to php not the other way around.
if everyone who came to a language had that language implementation changed
to meet their expectations of what it should be doing and how said language
would quickly deteriorate into complete shite ... something noone would want to
use or develop.

yes, it tells you your doing something impossible.

PHP != Python. python is pure OO. php is hybrid. you have to refactor your
code in different ways.
if your writing code that blindly makes use of a $user var that may or may not
be a valid object then you code is incorrect. not being able to trap Fatals is
essentially a non-issue as your code should be structured so that they cannot
occur.
there are a number of ways of dealing with the issue you have.
1. test the validity of the object
if ($user instanceof User) {
// do something
}
2. start using exceptions
try {
$user = UserGetter::get($id);
// do stuff with $user
} catch (UserException $e) {
// handle exception
}
// where UserGetter::get() is something like ...
class UserGetter {
static function get($id) {
$data = getUserDataFromDB($id)
if ($data)
return new User($data);
throw new UserException("$id is invalid");
}
}
what this comes down to is this, python gives you exceptions free of
charge, php asks you to implement and throw them yourself ... this is
primarily the result of php's procedural legacy. ce la vie.

Yes and maybe that is wrong two. But besides that, there is a difference between the two. It hardly happens that a bug results in a call to a non-existing function. But a bug can easily lead to an uninitialized variable which is then treated as an object. The problem with Fatal errors is that there is no way for me to handle them. I use an error_handler in the production system. When an error or unhandled exception occurs it displays an end-user-friendly error message and then sends an email to our team's mailbox. Working with arrays I can handle all sensible run-time errors using this methods. Working with objects, I apparently cannot, because Fatal Error aren't handled by the error_handler. That's a serious problem because it completely hides a likely group of errors from the notification system. I hopes this motivates the question a little better. But the question remains.
