I am following the steps in the BUILD YOUR OWN DATABASE DRIVEN WEB SITE USING PHP & MYSQL 4th Ed. I am having some issues when I come to the Database Connection section. First off, when I start Apache on my Windows XP 32bit machine, I get this: Error parsing <install root>php.ini on line 1107. This is not one of the lines that were changed in the instructions of setting up Apache in your book. But Apache does start up after that error is dismissed. So, I am wondering if this is why the DB connections fail. Second, when I try run the page that is to make the DB connection to MySQL, I get this error: Fatal error: Call to undefined function mysqli_connect() in F:\Apache Software Foundation\Apache2.2\htdocs\connect\index.php on line 2 . LIne 2 of this file is as follows: $link = mysqli_connect('localhost', 'root', 'stella'); Any suggestions? Thank you in advance for your help.
