No.
But if you need external access, global is the way to go...
I can't think of any inherent property to 'static' that is not already
encompassed by 'global'... Am I missing something?
Initializing $data to "" and then adding to it as an array is pretty
ugly code, imho. Initialize it to an array() not "" if it's an array.

PHP List,
Perhaps one of you might know the answer to this, because I certainly do
not, nor do any of my coworkers. The "problem" is that scripts on our OSX
10.4 (our local development machines) and RedHat/Debian linux servers do not
throw the "headers already sent" message. I could have an entire page of
html, php code, whatever I wish and call session_start() at the bottom of
the page and everything would be fine. No errors on screen, in error_log,
or anywhere else.
I know this is invalid and so do most webservers/environments because
everywhere else I have ever coded I see the "headers already sent, output
started at" message. I have used Windows, Linux, and FreeBSD versions of
PHP with Apache 1.3 and 2 and had the error print out as expected.
I want to know if any of you know the reason why this is happening. I would
prefer the strict error messages to help keep everyones coding in check.
Unfortunately I cannot for the life of me seem to find any configuration
settings which point to this. Any pointers or help would be greatly
appreciated.
Thank you in advance!

To check were the php.ini file is suppose to be, create a page
called like phpinfo.php and put the line:
<?php phpinfo();
That will have a section showing where the Configuration file php
is looking for. if it just specifies a directory, then it mean
there is no php.ini file in that directory an php is just using all
the default values.
The things that would cause the error message not to show up would
be things like:
'php.ini:display_errors' if set to Off, it wont show any errors
'php.ini:output_buffering' if is set to something other than Off
then there is a chance that php got lucky and didn't send any
data yet by the time it got to the session_start() call.

Mostly out of curiosity, but also somewhat out of my
troll-like and pedantic nature, what happens if you
start your scripts with:
<?php
error_reporting(E_STRICT);
??
And, the obvious troll question: you do have session
support compiled?

Greetings!
I am building a website using PHP 5.1.2 and MySQL 5.0.18 and I am using
windows xp with IIS.
All the hosting companies I have contacted are using php 4.x.x and mysql
4.x.x or 3.x.x, on linux I suppose.
Are php versions the same for every os/platform?
Thanks in advance.
PHP 5.1.2 is the 'latest and greatest', or pretty close to it.
For various reasons, hosting companies tend to be reluctant
to upgrade such things; the old (USA, anyway) engineer's
adage "if it ain't broke, don't fix it" comes to mind --- and
these hosting companies figure that it's working and they
don't want to take chances, IMHO.
An even greater reason behind this fact/trend that you notice
is that PHP has become so well-known that websites of all
types are using it, even those whose "webmasters" don't know
much about how to write in/use the language; therefore they
are using "c'n'p ed" scripts from the net that may date back
some distance in Net-Time; register_globals must be on,
"long" global arrays (although they're pretty much backwards-
compatible with PHP 5.X), etc., and deprecated $foo ad nauseum.
The hosting companies don't want their helpdesks flooded with
calls of "OMG my site is down!", and "Why doesn't my shopping cart |
contact form | uploader | downloader | gallery | ... work???"
During my last local update of PHP I finally updated php.ini
as well; took me quite a while to get my business interface
running probably again because I'd written the first scripts
with "short tags" years ago. That's the sort of thing they don't
want to have to deal with just yet. Of course, the day will come
anyway, so they'd better be getting ready....

Hi, folks.
A few of you provided me with some great feedback. I've encorporated
most of the suggestions into the examples. There is a bug fix in
there, too (get_tag_contents()), so be sure to check it out. =)

Now that we all know how to auto-complete city and country, let's use
it. ;-) If anyone can find a royalty-free way to automatically
complete region (provice/state), that'd be great. E-mail me directly,
as I've removed myself from the mailing list (too much traffic).
Thanks for all the help!

Hi,
I have to rewrite an application from ASP. In this application, I
receive DBase files which may be saved into Oracle.
In ASP, I used a generic driver and I made SQL requests on these files.
It is possible with PHP on Linux ?
Do you have some examples ?
Thank you very much.

I am having a problem with a shop system. I can't add values into the
MySQL
DB via a PHP statement. The values are being transferred from one
page to
another (know that from the echo statement), but the SQL statement isn't
working.
The statement is as follows:
$conn = mysql_connect($DBhost,$DBuser,$DBpass) or die('Unable to
connect to
database');
$t = $_GET['newdvdtitle'];
$y = $_GET['newdvdyear'];
$c = $_GET['newdvdcost'];
$p = $_GET['newdvdpurchased'];
@mysql_select_db("$DBName") or die("Unable to select database $DBName");
$sqladd = "INSERT INTO 'dvd' ('id', 'title', 'year','cost','purchased')
VALUES ( NULL , '$t', '$y', '$c' , '$p' )";
echo $sqladd;
using echo to find out whats' in your variable is a good start, also
take a look a print_r() and var_dump() - they given more feedback
regarding
passed in vars.
it would have been useful if you had actually posted the output of the
echo statement.
$result = mysql_query($sqladd);
try adding something like:
if (!$result) {
die(mysql_errno($conn) . ": " . mysql_error($conn) . "\n")
}
Very good habit to be into. Also, adding the query will help during
the "debugging phase" of development. I generally use something like:
mysql_query("$query") or die("Error in query: query was $query and MySql
sez: ".mysql_error());
If, as the continuing thread suggests, the query is actually empty,
the above would make that rather obvious right away.
HTH,

hello
i have been trying to learn php.
what is the best approach to learning php for someone who has no
programming experience?
i am very familiar with html, xhtml, and css. i'm not an idiot when it
comes to using computers.
i have bought several books and have subscribed to a couple of the php
mailing lists, but i feel that i could be doing more to learn php.
what approach (and steps) did you take in learning this really cool
scripting language? should i look into taking classes or stick with an
autodidact approach?
any advice and/or opinions would be greatly appreciated.
thanks.

experience. A simple but effective way is to choose something that
interests you, create a small database and then a PHP interface to fill it
up and display information out. If you can't think of an interest, ask your
friends and family for something they want to keep records of.
Load the free (as in beer) software you need on your computer (LAMP or
WAMP?) and start making examples. If you can't seem to get motivated on
your own, involving someone else who really wants to see results is probably
the best motivation.
Keep in mind the goal of learning PHP and not making the best display, user
interface, database tables, security (at first), etc. Getting some results
will probably help motivate you further. Don't wait to finish the books
before you start. You won't remember it all anyway, so just skim the books
and use as references.
good luck,

I honestly believe the best way to learn any programming language, aside
from perhaps tertiary study (and then only perhaps), is to start out
with a project and ask the questions you need to solve as you build that
project.
It should quickly become obvious which things you need to learn, as you
plan and pursue the project.
Some of those questions might be:
- I need to access data in a database. How do I do that?
- I need to be able to carry data from one page to another, how do I do
that?
- I need to be able to store 'stuff' at one point in a page (ie, maybe
data I got from the database) so I can use it again at another point in
the page.
And so on.
Armed with those questions, you can go through your books, go through
helpful web sites (don't underestimate the quality of the docs and
comments on php.net) and ask questions in forums like this one.
Another useful way of picking up knowledge that might not be relevant to
you right now, but will probably be handy to know later, is reading
threads in this mailing list. That way you learn about the kinds of
problems others have encountered, and the suggestions for solving them
they have received.
Much warmth,
Murray

I started out by getting a reference manual, one with every function
describing what the function does. Just like the php.net online function
reference but one that can be read lying on the couch.
Now when I need some code to do something I'll remember there's a function
for it (maybe) and I go to php.net and search for it.
I search for PHP examples online for more advanced stuff than I can do and
study it. This gives me some knowledge of proper approach to coding; when to
use what.
Finally if the code looks funky I send a snip to this list and someone will
suggest a better function or approach.
Oh yea, this is great, I use Dreamweaver's (grimace) PHP coding abilities to
get projects started. Dreamweaver can do the preliminary basic database
connection stuff: INSERT, UPDATE, DELETE pages. Then I hack the Dreamweaver
code.
Doing a MySQL tutorial is a good idea too.

"Also in Oracle's crosshairs: closely held Zend, based in Cupertino,
Calif. Zend's PHP software language is one of the most prevalent on the
Web, present in more than 18 million Web sites. The company, which snared
headlines last year when Netscape co-founder Marc Andreessen joined its
board, has been trying to extend its success with the Web into business
applications. Zend could sell for $200 million, according to one source."
