Problem solved:
I restarted my computer and after that apache loaded ibm_db2 extension.

My conclusion:
1. When you add some extensions to php.ini, you need to restart windowsin order to get those extensions available through apache2. However, those extensions are instantly available if you use phpcommand line interface
Anyone disagree?

Also, phpinfo() won't say nothing that module ibm_db2 is in use

More info:

php_ibm_db2.dll file is in folder C:/php-5.2.1/ext

php.ini:
extension_dir = "C:/php-5.2.1/ext"
extension=php_ibm_db2.dll

httpd.conf:
AddType application/x-httpd-php .php
LoadModule php5_module "C:/php-5.2.1/php5apache2.dll"
PHPIniDir "C:/php-5.2.1/"


Can someone point out the right direction for me?

I'd say that on Windows, when you, or software you install, modifies the
PATH environment variable, and a service, like apache, relies on a directory
being in the path, you have to restart Windows in order for that service to
"see" the new path.

In other words, services get the new path only after you reboot.

Good morning fellow coders
I've been working with PHP for a little over 5 years now, and it even got mea cute office and a good salary... but even though I can make a living offof it, I am still wondering about a few little things.
Whenever I see people put their code up for review, I realize they mostlyuse print instead of echo, while I am using echo 99% of the time. Actually,I can't even remember when I last used the regular print.
What do you guys use, and what is the advantage (if ther is any) of printover echo? And I am not talking about print_r or anything, just the regularprint. :o)
All the best!

print returns a result, echo doesn't. This makes echo slightly fasterthan print, but I doubt theres any significant speed improvement usingecho instead of print.
I use echo, but thats just because its a habit.

Me too. I use echo. Print is a function.

There's no significant difference between them. My advice: choose one,
and stick with it.

Hi nothing to do with the actual topic, i am just wondering how you get this
"internals" information you all seem to know so much about, it is very
interesting and i'd like to add it to some of my "late night" reading if
possible :)

Just guessing, but I'd say probably the source code. That's where mostof the internals of PHP are documented. ;)

Several sources... the C source code as Stut has presumed :) Also from
reading the PHP-DEV list where the source is often discussed.
Additionally, some of it is from my early Computer Science background
where there's a large focus on data structures and algorithms.

Cheers,
Rob.

Well, I did provide the log on and password on a subsequent post.BUT, I didn't try to make it hard to guess, that wasn't the point ofthe post. I was trying to see what files were considered "secure" andwhat files weren't.

I can then visit b.php and auth.php, which do not seem to generate

As you said "PHP code is executed completely out of context, in a manner you

So, I try to make my include scripts produce nothing when calledindependently. I've seen techniques where a token must be correctbefore running, but I just make my includes dependant upon variablesin the calling script.

If you put the stuff you want to keep private OUTSIDE the web-tree,
and provide a PHP gate-keeper to get to it, you reduce your risk.
I'm sorry, I should know this, but I don't.
You see, I work totally in hosted environments. They provide me withseveral folders from "anon.ftp" to "web_users" (including a "private"folder).
I start building from inside httpdocs folder where I place anindex.php file and then branch out from there. Now, where is "OUTSIDEthe web-tree"?
It's a lot harder to screw up bad enough to configure Apache to start
serving up files directly from a "private" directory.
I have a "private" directory, but if I place files in it, I can'tread them via php -- I get a:
Warning: fopen(): open_basedir restriction in effect.
I've read how one can turn that off, but I have not been successfulin doing so.

Now you got me going, how did you get that? Even my php scripts can't read it.

Or are you putting me on? Send me a copy of it back-channel.  :-)

Right,

Have tried the full url for the header and it still doesn't work. I may have 
to resort to...javacript redirects unless someone can suggest a way around 
it.

Here is the phpinfo();

http://s202801613.websitehome.co.uk/info.php


Is is 1and1 hosting if anyone had had any experience of them.

Can you re-iterate what is happening - I have a site with 1and1 and use
header() with no issues.

I have several sites with 1and1, and I use header() with no problems.  The
main issue I have run into with header() is that your script can produce NO
OUTPUT prior to the header() call.  Not even a whitespace, else header()
will not work.

JM

--- End Message ---

--- Begin Message ---

That is, unless you use output buffering. It may not be the most elegant
solution (using header() to redirect users increases server calls), but I
built a template-driven php site that calls:

<?php ob_start; ?>

...depending on certain conditions which means I can then use header() even
after I have started output.

--- End Message ---

--- Begin Message ---
Read about output buffering, it's your solution and well worth time learning 
about.

if you look at your error_report setting.  is it 2037

somebody correct me if I am wrong, but isn't this setting

I ran this on my older system and found that
(E_ALL & ~E_NOTICE & ~E_WARNING) all together = 2037

so, even though you have display_errors turned on, it isn't going to show them.
you need to set this to just E_ALL

<?php
error_reporting(E_ALL);

...
?>

This should solve your problem
