The demonization of goto was due to the kind of goto found in older languages that would either a) goto an arbitrary line number where line numbers might change as new line numbers were needed (who invented that concept anyways???). The other was where you might jump willie nillie to a globally defined goto label that might appear anywhere in a program versus jumping to a goto label within a well defined context. The goto added to PHP allows jumping only within the current context... you can't jump out of a function or into a function, nor as the help says can you jump into a loop, or into a switch statement. What this does is greatly simplify some types of coding where you might otherwise have to use multi level breaks, or define a temporary variable whose value is checked at various breakpoints. Goto resolves these issues by allowing jumping directly to a defined label within the context. Additionally, implementation of things likes parsers are extremely succinct using goto semantics. Goto has a place in languages, just not ad-hoc poorly thought out goto.

Yes, when I went to university the students were young adults. Now they are
just kids!
When I started programming (in about 1967) I worked for the Commonwealth
Scientific and
Industrial Research Organisation (CSIRO) in Australia. They had a little
computer (a CDC
3200, costing $500,000 and with 32K of 24 bit words of core memory) in each
capital city,
and a big computer (a CDC 3600, costing $2,000,000 and with 64K of 48 bit words
of memory)
in Canberra. The little computers filled a large room, and had about 20 people
operating
them. The big one filled a whole floor, and had about 50 people operating it.
I had to enter my programs on punch cards, and a courier would collect them
twice a day
and take them to Clayton (another site about 10 miles away). Then he would
bring back the
listings from the previous trip. After the morning run we had about 20 minutes
to fix
obvious bugs before he collected the next batch, and we had overnight to fix
the afternoon
run. When I got more ambitious, and started using the big computer, the cards
were taken
to Clayton where they were transferred to mag tape, which was couriered to the
airport and
flown to Canberra. The tapes were run overnight, and the listings written back
to tapes,
which were flown back to Melbourne next morning, taken to Clayton, transferred
to paper,
and brought back to our site. There was often fog in Canberra, which would
close the
airport, so if we were lucky we would get three runs in a week. Any trivial
change would
take a week to debug.
We were programming in Fortran, and the I/O support was extremely primitive.
You had to
specify the format for every value you wished to read - eg F10.3 for a 10 digit
floating
point number, with three digits after the decimal point, and you had to place
the decimal
point in a specific column on the card. Despite all this I wrote a complex
program for
analysing linear electronic circuits. It was effectively an interpreter for my
own
high-level language.
I never understood how subroutines worked, as the concept of stacks had not been
developed, and you could jump into or out of loops and even subroutines with
impunity. It
also had an 'assigned goto' instruction, which was perfect for writing 'write
only'
software. My program was very simple. It consisted of a loop:
Assign initial pointers to switches 1 to 3;
Start: read a character;
if it's a number { GOTO switch_1; }
if it's a punctuation mark { GOTO switch_2; }
if it's anything else { GOTO switch_3; }
GOTO Start;
Initial_switch_1 procedure:
.
GOTO start;
Each time I found something interesting I would assign a new pointer to the
appropriate
switch. This gave extremely compact code, enabling me to get my complicated
program into
the ridiculously small memory, but I soon found that it was virtually
impossible to debug,
as the settings of the switches at any moment depended on the whole previous
history.
Presumably others made the same discovery, as the assigned goto never appeared
on any
subsequent computer.

If your host is only using PHP4, you probably should switch because who knows what else they've chosen not to upgrade. Check out the forums at http://www.webhostingtalk.com/ for info on that. Just keep in mind that neither PHP 5.3 (where GOTO actually comes into play --- I typed PHP6 without thinking) nor PHP6 are yet officially released, and aren't likely to be in production anywhere yet. -- daniel.br...@parasane.net || danbr...@php.net http://www.parasane.net/ || http://www.pilotpig.net/ 50% Off All Shared Hosting Plans at PilotPig: Use Coupon DOW1 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

QuickBasic (actually QBasic, and then later QuickBasic when my mom shelled out the money for me to buy it) was my first language. I remember being completely flabbergasted when I found out they packaged an interpreter with DOS, and it had been under my nose the whole time. I think my first "finished" program was a D&D character generator. Basically, just colored and formatted text with the output of 6 or so random number generations.

I wholeheartedly concur. The first programming language I taught myself was BASIC about 23 years ago. We may never see the inclusion of GOSUB in PHP, but GOTO is certainly worthwhile. Side note: I wrote a BASIC interpreter in PHP about two weeks ago.

Easily fixed. Just put:
$missing = false;
at the start of the loop, and then:
$missing[$oblig_fields[$i]] = true;
each time you find a missing field. Then the array keys for $missing will tell
you which
fields you have to fetch again.

Don't take me too seriously on this. But it riles me that the same peoplewho
threw out the
GOTO as being too dangerous could then introduce the break statement which, as
I said,
it's like a GOTO without a target. As a long-time assembly programmer, I found
the
judicious use of GOTO's made for far clearer code than the mess of nested
braces I am
forced to use in PHP.

Re: [PHP] Re: if elseif elseif elseif....
Rather than encoding all the variable names into one long unwieldy set of
statements, I
would put them all into an array, and then use a loop to process the array.
This way all
the variable names are together, and the next time you want to enter another
set of
variables you can use the same code, but read from a different array.
For example:
$oblig_fields = array('TitleN', 'first_nameN', '');
$ok = true;
$i = 0; while ($i < count($oblig_fields && $ok))
{
if (!isset($_POST[$oblig_fields[$i]]) || ($_POST[$oblig_fields[$i]] ==
''))
{
$ok = false;
}
else
{
$results[$oblig_fields[$i]] = $_POST[$oblig_fields[$i]];
}
++$i;
}
if (!$ok) { echo 'Scream!!!'; }
The problem with that is if I miss 5 fields, I have 5 page refreshes to
get to the end & actually successfully submit the form. If you keep an
array of broken entries (per my previous suggestion) you get all the
form fields missed in one go.
I'd just do a foreach instead of a while, count, and counter.
foreach ($oblig_fields as $field_name) {
if (!isset($_POST[$field_name]) || empty($_POST[$field_name])) {
}
}
I am sure you could use a "break" statement in place of the "$ok = false;"
above, but I
have never trusted the break statement. To my mind it is like a GOTO without a
target.
Must've been a bad experience ;) Always works for me.
It breaks out of the current loop (for, foreach, while - doesn't matter
about the loop syntax) or switch and continues executing the code
straight after the loop.

It's there, I just didn't include it as it is followed by a lot of
stringies:
$obligatoryFieldNotPresent = 0;
if (isset($_REQUEST["AddNewBooksRequest"])) {
$titleIN= $_POST["titleIN"];.snipetysnip...
