Call to undefined function mysqli_connect()

[robb73]

Unfortunately I can't get mysqli to work, I keep getting the

error message "Call to undefined function mysqli_connect()".

 

As everything works fine using mysql I am guessing its something to do with

my php install?

 

I'm using:

 

Windows xp pro sp2

IIS

PHP 5.1.2

MySQL 5.0.27

 

I have included extension=php_mysql.dll in the php.ini (in the WINDOWS folder).

I have also checked the extension to the extension directory extension_dir = "C:/php/ext"

 

The libmysql.dll is in the SYSTEM32 folder.

 

Bizarrely, when I check the version of Mysql using phpinfo() the version shown is 4.1.7

yet when using the MySQL command line client it shows 5.0.27.
