PHP-MYSQL-Apache MYSQLi_CONNECT questions

My 'mysqlconnect.php' simple connection test script returns a browser
message

"PHP Fatal Error: Class 'Mysqli_connect" not found in c:\\program
files\apache group\ .....\mysqlconnect.php"

I've been fighting this well-known problem for three days. I got the
application code and simple test script from a book "Teach Yourself PHP,
MySQL and Apache". I am not an expert but tried to rigorously follow the
installation directions. I have tried almost every combination / permutation
suggested by internet posters to no avail. Here are some basic questions;

- In which .dll is the function "Mysqli_connect" located? I think the
choices are
libmysql.dll (as installed in the c:/php folder) or php_mysqli.dll in
the c:/php/ext folder

- Is there a difference in version5 between enabling a php.ini extension for
MySQL and MySQLi ?

- Does the order of the PATH statement make a difference to MySQL when
trying to locate the .dll containing the Mysqli_connect function?

- Should there ever be more than one libmysql.dll in a working installation?

FYI, there are no apache error messages when the script runs. Also a script
using phpinfo() does run and records Mysqli settings.

Other info....

MYSQL 5.0.20
Apache 2.0.58
PHP 5.1.4
Windows Home XP SP-2

Thank you for your help

Any chance this is because this class isn't defined anywhere? The
mysqli extension defines four classes:

MySQLi
MySQLi_ STMT
MySQLi_ Result
MySQLi_ Driver

and Mysqli_connect is not one of them...

It seems to me you are confusing the MySQLi class with the
mysqli_connect method...
