MySQLi problem in PHP

[Malcolm Wright]

Although I've been programming for over 30 years I am new to web
development.
As an introduction I've been using a book "PHP and MYSQL Web
Development" by Luke Welling and Laura Thomson.
I've set up an Apache Server v1.3.31.
I've also installed MySQL V5.0.13 and PHP v 5.0.5.
I've gone through the installations several times. I'm reasonably
confident about the Apache Server but I have a problem with the
interaction of the PHP and MYSql.
I'm trying to connect to a MySQL database using PHP. I'm using the new
mysqli_connect structure. I've also tried the straight procedural
version mysqli_connect function.
When I run the code I get a "Call to undefined function mysqli_connect".
I've set up my PHP.ini file to point to the correct php ext file and
I've included references to the php_mysqli.dll but I still get the error
message.
In addition if I stop and then restart the Apache server - which is
linked into PHP - I get an error message saying that PHP can't find the
module php_mysqli.dll.
I'm sure I have defined my extension_dir correctly as
extension_dir = "C:/PHP/ext/"
I know the dll is in this directory but it is not getting picked up. As
this is currently a total block can anyone help please!

Thanks

Malcolm

The first thing to check is if your installation is using the version of
php.ini which you think it is.

Run a script containing only
phpinfo();

and take a look.

If that's all OK, then did you stop IIS when installing PHP and Apache? If
not, try uninstalling and reinstalling with IIS stopped.

Cheers

Did that and it looks as if its using the php.ini in c:/php which is
what I would expect. and take a look.

Don't have IIS installed. IIS is a server (I think!) and I'm using the
Apache server.
I stop the Apache server every time that I made a change to php.ini and
then restarted but it still doesn't see the php_mysqli.dll.

Well, what your phpinfo(); script says? Check the manual for it's
specific location of php.ini file. This file location matters!

Don't loose your hair rightaway! You might forget about all these
installaton troubles, just get a full php+mysql+apache package on
windows ... like xampp!

http://www.apachefriends.org/en/xampp.html

with MySQL 4.1.15 and PHP 5.0.5 ....

Just download the whole package and extract that to some root drive
a-n-d you are on the run!

Thanks for this tip Raqueeb. I've downloaded and got it working though
I'm still having problems. Do you know into what directory I have to put
the PHP source files?

Malcolm,

It's also possible Apache can't load the MySQL client library
(libmysqlclient.lib or mysqlclient.lib). Ensure this library is in a
path where it can be loaded.

What happens if you type just

mysql

at a command prompt? This will load the mysql command interpreter.

Hi Jenny,
Yes it responds with the mysql prompt and login. I can there get to the
normal mysql functionality. I set all the neccessary paths - which made
it all the more confusing that it couldn't see the dll.
Thanks

Strangely enough there was another person with exactly the same problem
as I was having - see "PHP Configuration Troubles" further down this
newsgroup. I followed the advice given in that answer, upgraded to
Apache2 and copied libraries as suggested and it all works now.
Thanks to all who responded.
