I'm having problems passing variables into included PHP files. How can I do this?
--- End Message ---

I may be repeating myself -- use the Nike solution: just do it! :-)
Global variables are implicitly passed to includes. Please provide more info if that's
not the case (not globals/globals somehow not being passed).

Make sure you include the tags <?php ?> in your include file for PHP
parsing. Included files are assumed to be text otherwise. You need to
provide more information if you have another problem.

Dear Members ,
Does anybody of you have a webserver at home
using ADSL or other connections ?
If any , could you tell me What would be the acceptable Hardware to run
5 or more sites at home with an
256 k ADSL ? (Memory , proccesor , etc etc )
Do I have to have Two Servers ? (The WebServer ) and the Intranet Server
to access through my computer ?
Would you help me please in a near future with a few questions about how
to set up and so on .....???
Thanks guys in advance

The answer is "that depends" For example my telco has me behind their own firewall,
and the IP number my NIC is seeing is 10.38.73.5 but the outside world sees as
142.177.238.56. Ah, the magic of NAT.
This can be overcome by using one of the, for lack of a better term, IP aliasing
services,
like dynamicdns.org. Their software constantly monitors the IP you come from and
maintains
a routing table. Thus someone looking for www.mysite.ca, would first of all be
directed to them,
and then to my IP.
If you are fortunate enough to have a fixed IP number, the above is moot.

Depends on traffic and what you're serving and the level of traffic. If mostly static
web
pages, almost anything from a P100 on up. RAM is always good. Many phone companies
meter traffic and allow only so many free gigabytes permonth, then they start
charging.
If you're not supposed to be running a web server on your connection, that's how
they'll find you.

This is really off topic for the list, and better addressed through a security site.
Do a Google
search on "firewall DMZ" and you will find some very comprehensive articles, ranging
from
general overviews to specific recommendations.
Generally the stuff at risk is on the web server and beyond, or on, your firewall
machine.
Important stuff is behind the firewall.

That's not really PHP specific, and would be better addressed on a security or
webserver
list. (Note how apolitical I'm being, not assuming you are using Linux or BSD and
Apache.)

You're welcome. There is some really good stuff out there.

If you want to write applications that take advantage of things that are
specific to one database, database abastraction layers are of no user to
you.
Although if you give up on some things, you can write database
independent applications making them more maintainable and take less
time to release them letting you reach a broader market. It is a
strategy that may worthy a lot of money if you run a software company.
For instance, Siebel CRM packages AFAIK does not use stored procedures
to be able to reach a wider market in less time.
Anyway, back to PHP database abstraction packages, Metabase abstracts
things that are possible to provide in a portable way, like data type
mapping, and even things that others have been copying like sequences
and limiting the range of rows that are returned by a select query which
are important things for Web development. Metabase also abstracts
database schema installation and maintenance which is a real time saver.

I asked this on php-install list, but got no response so here goes...
I simply cannot get session to work correctly. Here's the test script:
include("incl.php");
session_start();
$mine++;
session_register("mine");
echo $mine;
incl.php includes code to save/retrieve session information to/from DB. It
calles session_set_save_handler at the end.
What happens is I get an error because it is trying to read the variable out
and I get a DB error, but my session writing routine is never called...I
know, because I have a print in there. And of course, the var doesn't
increment upon refreshes - it remains 1.
I've seen this before, and it was fixed, but I forget how it was done, as I
didn't actually implement the solution (I hear and I forget, I do and I
remember, I guess). About my system:
FreeBSD 4.4
Apache 1.3.20
PHP 4.0.6
Any and all help appreciated.

I'm new to cyrus IMAP server and PHP4. I wanted to create a user for cyrus.
So I copied & modified the example of imap_createmailbox at
http://www.php.net/manual/en/function.imap-createmailbox.php
It was done with necessary substitution of for IMAP server and using "cyrus"
as user.
The error message was
Newname will be 'phpnewbox'
could not create new mailbox: Permission denied
I logged in as cyrus on the server I'm working on. I typed "cyradm" but this
error message came out
Can't locate Cyrus/IMAP/Shell.pm in @INC (@INC contains:
/usr/lib/perl5/5.6.0/i5
86-linux /usr/lib/perl5/5.6.0 /usr/lib/perl5/site_perl/5.6.0/i586-linux
/usr/lib
/perl5/site_perl/5.6.0 /usr/lib/perl5/site_perl .).
BEGIN failed--compilation aborted.
Could the problem be the misconfig of IMAP server. Pls advise. Thanx.

I am looking into installing php on some of our hospital servers and was
wondering about licensing issues. Are you suppose to purchase any type
of license for installing php on a commercial server? It seems a little
on the strange side that they (the php people) would just let you
install and use their product for free, what do they get out of it?
Thanks for any information,

Well, PHP is not under the GPL. But you still don't need to buy any sort

Hey guys,
Im need to generate an email and Im trying to keep the exact spacing
I use when I define the body of the email. When the email is sent and i
view it with Outlick Express or simply use Pine, the spacing is all out
of wack. (Too many spaces here, not enough spaces there)
I think i need something like Perl's Format features but not sure.
Any advice ?
Thank you,
Steve Maroney

Is this a plain text email message or MIME encoded, eg HTML? If the former, then the
spaces have been inserted
by 'authoring' program. If by spacing you are referring to vertical spacing/wrapping,
then that is limited by
some email clients.
Have you ECHOed the message body prior to message transmission to verify when/where
the spaces are
added/subtracted?

What WYSIWYG editors are you guys using with PHP templates? I'd like to
layout pages, frames, multiple levels of graphics with a WYSIWYG editor.
I looked at an online template from the macromedia site, and it is
completely unformatted and has some unprintable character in it at every
<b>. It is completely useless for putting PHP template information in. I
don't know if their program 'dreamweaver' actually MAKES the templates
that way. I'm downloading their trial version as I type, (24 meg
COMPRESSED!) They also obfuscate, or use incomprehensible jargon for
every single action to make people be in their own mind set. Everything
from ftp'ing, to graphic insertion has a 'macromedia name'. I'll play
with it, but so far, from the help links on their site, I'm not
impressed. They did get THE BEST REVIEW from WebMonkey though.
Any advice on this would be much appreciated. I am sick and tired of
hand coding HTML. It is FAR from logical. That's why I like php, good
logic, power, and flexibility. Usually, it does what I tell it to, DAMN
IT! Not HTML, though.

Hi guys ,
I was Wondering if it would be possible to write a proyect like Control
Panel or WebMin (both are in Perl ) using PHP instead or PERL ?
Would it be possible ?
PHP has the power and flexibility like Perl to write TRUE Systems programs that
could be able to manage all the aspects related to System Administration ??
If there any proyect I would like to hear about it and join it .
Thanks , I would like your opinion about this topic .

That depends on your application. With intelligent caching
on the user level (i.e. caching HTML output in the file system)
there are some PHP applications who can handle 17 reqs/s
easily. I'm sure there are also PHP applications who can handle
more reqs/s.
If that doesn't suit you, then you can deploy caching systems
on the ZendEngine level, i.e. tools like PHP Accelerator (free),
APC Cache (free) or the commercial ZendAccelerator.
Finally, if this isn't enough, you should scale by hardware.
Furthermore you should be aware of that tuning PHP is not the
only thing you have to do. Most bottlenecks are the database
you use (i.e. wrong table design, no indexes on relevant fields
etc.) and finally you should drive into tuning your webserver.
For MySQL you should try to use HEAP tables (tables that are
completely in RAM) when having many SELECTs.
If your website is delivering many static pictures (<img ...>),
then you should make a subdomain images.foobar.com. Put a small
webserver like thttpd on images.foobar.com and let it deliver
those images.
Don't use <img src="makemyimage.php?id=5"> because that creates
one PHP request per <img> Tag inside your HTML code. Instead, try
to cache your pictures in the filesystem (on the images.foobar.com
server) and let it be <img src="http://images.foobar.com/cachedimage5.jpg";>.
Have your eyes on the whole thing (webserver, DB, html code,
images, ...), not only on PHP when tuning.
If you need further consulting tips, send a private e-mail.

Hi,
Does anyone know where these have gone, or have them archived somewhere?
Google hasn't cached them.

Alternatively, anyone who has/has done code to take the headers, and
only the headers, of posts in a newsgroup and whack them into (& update
with new entries) a database, that would be nice to save me the coding
time :-)

[Sorry if this is a re-post but I have been having some email problems and
cant find original in the archive]
I have a PHP application that is working fine on my Windows 98 system but
when I try it on my Windows 2000 setup (which has recently had PHP/MySQL
installed) there is a problem. When I post from a form with a Browse/File
field when I check to see if the temp file exists it douse not. This check
is being done in the page being posted to. The strange thing is that the
file the varable is set to is something like E:\WINNT\TEMP\phpD4.tmp and I
thought PHP used tmp (E:\tmp is where the session data is held).
Any idea what is wrong.
Regards,
Ben

On this front douse anyone know of any companies who will compile an app as
I cant afford the compiler but will need to do this in the future. Is it a
stand alone and is it easy to install?

I am involved with creating a website (i am the systems guy not the
website programmer) on an older computer, a p133 with 80meg of
ram. Since php is by default loaded with apache in the slackware
installation I have chosen. I have told the website programmer that he
will have to use php for file uploads to the site as mod_perl is eats too
much system ram. I have to have setup that will allow the uploading of some
fairly large files > 50mb
Because this is NOT clear in the php manual on file
uploading I need to know if php uploads the file to a memory cache first
then flushes the uploaded data to the chosen uploads directory or whether it
writes the file to disk as it is being uploaded?
If it is the former I will have to look at another solution.
