RE: [users@httpd] Sometimes getting 'Premature end of script...'
Thx for the advices, Owen!
I use MySQL, I read and write files in these scripts. User input
is not really intresting. It comes at the same values sometimes.
I also noticed that this error comes when I use Php-MyAdmin!
Different requests make these errors.
(Anyway I looked at its code and the header is correct.
I am sure there should not be errors like this in the MyAdmin scripts.)
So I guess that must be a problem of misconfiguration.
Anyway if someone can answear to me the following things it can
be useful:
1, Is it possible that MySQL 5.0.0a (alpha!) makes the problem?
If so why I get php header error?
2, Can SafeMode solve such problems? If I turn it on makes the
scripts more reliable? (Speed is not really needed in my case.)
3, Can u suggest some links about how to make the server more
reliable? Programs would be also nice.

Welcome, Dave.
I concur that the Apache, PHP, MySQL platform is the preferred route to
take.
Both PHP and MySQL have excellent references on their web sites
(complete with search facilities and user comments). In addition, both
have very active and responsive mailing lists.
http://www.php.net/manual/en/langref.php
http://www.php.net/mailing-lists.php
http://dev.mysql.com/doc/mysql/en/index.html
http://lists.mysql.com/
If you have ever considered getting into Linux, this would be an
excellent time to do so. Most Linux distributions include Apache, PHP,
and MySQL -- all integrated and configured and ready to go. (The
resulting combination is known as the LAMP platform -- for Linux,
Apache, MySQL, PHP -- and is the most popular web development platform
around.)
You should also be sure to have a good basic understanding of the HTTP
protocol. Of all the prototcols in use on the Internet, HTTP is one of
the simplest, but many developers skip this step ... to their detriment.
Beyond that, rather than list a lot of resources, let me just say:
--The Internet is full of excellent resources on web development
--Google is your friend
Good luck!

Sounds like WE could all learn a thing or two from
YOU!

IMO, the best tool a web developer can have is a good
text editor. But I digress. When I had RoadRunner
internet, I ran my own web server on my network. You
just need to give it it's own IP address, or set up
port forwarding from your router. Most DNS providers
offer a dynamic IP service. You set up a program on
your server that automatically detects and updates
your IP with the DNS provider. I had this setup for
several months and it worked like a charm.

Excellent idea. I noticed another user reccomended you
set up a Linux box. I second that wholeheartedly. You
can use an old throwaway PC or one that someone is
getting rid of. Just set up a good Linux distro
without a GUI or any of the fancy stuff you don't need
and it will make a fine web/php/MySQL server. I've got
an old K6 266Mhz with 72mb of RAM on my internal
network doing just that. It also makes a handy MP3
server so I can listen at any computer in the house
(and even my Xbox!)

[users@httpd] New to Web Development
Posted by Executive Benefits Resources <EB...@kc.rr.com>.
Sorry for the most elemental of situations but I am new to the web
development arena and am interested in building WB-database applications
for friends and family. I used to be a programmer back in the early
70's (BAL, COBOL, FORTRAN, RPG, CRTs linked to mainframes, you get the
picture) and I got nominated to build a web-based hobby/business.
I operate on a home network consisting of a laptop with MS-Office XP
Standard and a desktop (my son's) with MS-Office XP Professional, both
of which are Version 2002. I am PC literate as it relates to MS Office,
Excel, Word and PowerPoint and have never done anything through MS DOS.
I have high speed internet through Road Runner.
I would like to initially build a web server and applications on my home
network for learning/experimenting (no one but me will have access)
before I venture out of my box.
>From my initial very broad-based reading, it seems I should work with
Apache, PHP and MySQL as well learn the basics of HTML and SQL which I

Does anyone have sources you can point me to and/or thoughts on how best
to proceed without feeling totally overwhelmed moving forward with my
new ambition?
Thanks for any empathy and I apologize if there was a better forum for
my question,
Dave
