Just a question out of curiousity for the language lawyers out there. Why is
it illegal to begin a variable name with a number in php?

[/snip]
This is fairly standard in programming languages. Years ago (sometime in
the 70's) the reasoning was given to me, but I have long since replaced
the data at that address with some other, probably trivial, fact. I
tried a quick Google, but no joy.

I don't know why in they do it in php, but I would guess that it's one of those
legacy things.
Back when I was programming with rocks, a language called FORTRAN came along
(before FORTRAN started having Roman Numerals after its name).
The rules of this new language was that integers could only start with the
letters I, J, K, L ,M, N (hence our custom to use $i , $j, $k for loops) and
all other real number could start with any other character but those, and could
not start numbers -- however, both variables could contain numbers but were
limited to just six letters total. (But note we didn't have to start variables
with a $ ).
As far as strings were concerned -- what the hell were those? If you wanted to
print something, you use a FORMAT statement and therein you might find syntax
that could start with a number, such as 4F5.0, but that was just to format a
number for print -- it had nothing to do with a variable name.
In defense of the decision of the time, I doubt that many of you remember IBM
punch cards (one card for every line of code in your program) but it was a
*great* deal easier to review and edit your stack of code if you kept numbers
and letters separate with different meanings.
So, my guess is it's legacy.
My question to you is, what are you passing on that in 40 years some young
programmer will ask "Why is it illegal to..." :-)

最近セフレを探す女の子が増えました！
その響きだけ聞けば「なんだかなぁ」って思う人もいると思います。
でも、実際は大多数の人とセックスをしないようになるので衛生的ですし、
恋人だと少々重く感じる人がいるからこういう関係が成り立つわけで、
一緒に買い物にいったり、映画を見たり、恋愛相談をできたりする

Would it then be posible to restrict it in some other way, for example
using chroot? Or do I just have to make sure that the modules come from
a source that I trust or look through the code?

Hey Chris,
Thanks for replying.
Dont worry about it, solved it, made a silly mistake
on my part but corrected it by just copying the code
from the session_destroy page on the
manual...destroyed the session and the cookie and all
works good now.
Thanks!

Hi,
can anybody give me a recommendation on a good
html->pdf converter. Checked google and there are
loads of classes, this one looks like one of the best
though (even in price):
http://www.rustyparts.com/pdf.php
Anybody else using this? if yes, would appreciate any
"cons" of using this class.
Or, if you are using another class to do the above and
think its the next best thing to sliced bread, I would
appreciate you sending me the link so that I may try
it out.
All I need is a pdf generator that will generate an
exact (or as close to exact) copy of the html page
(that was generated by php, not a static html page),
nothing fancy, no permissions etc
Thanks!
Ryan

Depending on what you need (CSS support, good table support and so
on) and which plattform you are working with it might be a good idea
to have a look at: http://www.digitaljunkies.ca/dompdf/
There are also several on-line services available like: http://
www.pdfonline.com/
If you are on Mac OS X, I would definitely recommend looking at the
Core Image functions within the Quartz 2D layer in Mac OS X. Core
Image has also subroutines for PDF output (this is why you can save
any document from any program in Mac OS X as a PDF file). You can
access those APIs for example via Python.
http://developer.apple.com/documentation/GraphicsImaging/Conceptual/
drawingwithquartz2d/dq_python/chapter_17_section_1.html
This might give you some ideas where to start.

Hi Richard,
I'm basically building a custom mysql table to delimited text file
function for a membership site. So I've got a lot of typical
demographic info fields like name, address, etc. The site owners
would like to dump the membership information for their own purposes,
but they don't always want a complete set of all data. So the form
lists each field with a checkbox to determine whether it is desired
in the exported text file. To simplify things, the names of the
checkbox form fields correspond exactly to the names of the related
fields in the mysql table. So if there is a field named
home_address1, the form checkbox is also name="home_address1". When I
capture the form data, I iterate through the $_POST variable and
create a custom query based on the checkboxes that are checked. So
the form presented looks like:
<snip>
<input type="checkbox" value="1" name="prefix">Prefix</input><br
/>
<input type="checkbox" value="1" name="first_name">First Name</
input><br />
<input type="checkbox" value="1" name="middle_name">Middle Name</
input><br />
<input type="checkbox" value="1" name="last_name">Last Name</
input><br />
<input type="checkbox" value="1" name="suffix">Suffix</input><br
/>
<input type="checkbox" value="1" name="home_addr1">Home Address
(Street)</input><br />
<input type="checkbox" value="1" name="home_addr2">Home Address 2</
input><br />
</snip>
Since the form fields names correspond to mysql field names rather
than just a plain index array, I can use the keys thus:
<snip>
$exp_format=array_shift($_POST);
if ($exp_format=="tab") {$delimiter="\t"; $filesuffix=".txt";}
if ($exp_format=="csv") {$delimiter=","; $filesuffix=".csv";}
/* reset three array elements in the POST superglobal, they are
flags and
should not be part of the custom query */
$mem_activity=array_shift($_POST);
$part_pref=$_POST['part_pref'];
unset($_POST['part_pref']);
$query="SELECT mem_id, ";
foreach ($_POST as $key => $data) {
$query.="$key, ";
}
/* chops off the last space and comma */
$length=strlen($query);
$query=substr($query, 0, $length-2);
</snip>
So what I really want to know is if there is some kind of best-
practice method of rearranging the order of the items in a $_POST
array without rearranging the elements on the original form, or post-
processing them item by item.
Thanks for any insights...

The script that processes the form looks like:

I probably should add some more details to my question:
The names of the form checkboxes could be changed from ie:
bool_careers, bool_speaking, bool_internship, etc. to a single array
bool_questions[], for instance. The problem with that is that I am
using the form checkbox names later to process related data.
Specifically, I am building a user-input based query. So if the form
checkbox names are the same as the names of the variables in the
database, it makes for easy creating of the query, since the names
become associative keys in the $_POST array. I iterate through the
$_POST array, checking each for true/false state. If the checkbox is
checked, I add the associative key name to the query. Eliminating the
checkbox names in favor of a numerical key only would make this more
complicated.

1. Use Keys in your form like a[1],a[2]
2. order the array by usort (alphabetically or whatever u prefer)
that way => 2: yes it is.

Since you asked for some theory... theorically, you won't rely on
javascript to prepare/validate/whatever some data to the server, that's
what server-side scripts are for.
Note: you may use JS to make things quicker if possible, or to
pre-digest the data, but you shall not rely entirely on JS.
You say that not all browsers support the javascript functions you
pretend to use, and that not all them support Ajax either. That sounds
just like saying that not all browser will have javascript enabled
--that's why you shouldn't rely on javascript
Although, this isn't a javascript list, why don't you send whatever you
were trying to solve this issue? the code that uses JS functions not
supported for all the browsers that will potentially run the script (as
well as what these browsers are) Most likely someone will be able to
help you this way.

Hello;
i'm scratching my head with a difficulty.
The situation is this.
A script begins with one indexed array (not associative) and one other
indexed array
with the same values in a different order, the final order.
I want to create an interim array and progressively re order the array
until it matches
slot for slot one of the original arrays. At this point the script is
considered completed.
One important factor is that I'm looking to write this in javascript and
the interim
array will be altered by the actions of a web page user.
Why am I asking the php list? Because I have a better chance of getting
an answer
here. I'm not looking for help with javascript, specifically, just how
one would go about
this task. Answer with php code and some theory if you wish and I will
try to translate
it into javascript.
Some javascript functions I might use aren't supported in all the
browsers that will
potentially run the script.
I might resort to using Ajax and let php keep track for me. But, then
again not all
browsers will do the Ajax either (as I understand it).
