[users@httpd] New to Web Development

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
have already started.

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

Subject: 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.

Gabor

prints the response header ("content-type: text/html\n\n"). There is an 
occasional problem with your code which is not properly trapped. Do 
you access a DB?, write to a file? read from a file? do any calculations

using user input? Any of these (and others) can cause a failure which 
depends on user input. To debug:

fauilure by re-issuing the same request (ie, same user parameters).

details

instead of numbers, numbers instead of words, even entire programs!)
