newbie needs help in getting php and MySQL integrated

All, I'm a newbie trying to learn PHP and MySQL (following examples in a book "PHP and MySQL by Larry Ullman". I am running: Windows XP SP1 Norton Antivirus and Internet Security Apache 2 PHP 5 MySQL 4.0.16 All seem to work. I can run PHP scripts on the Apache server without any trouble. I have MySQL running as a service and the basic SQL command line commands and winmysqladmin shows all ok (to my limited knowledge so far). So as the PHP installation instructions stated : Since PHP 4.0.5 MySQL, ODBC, FTP, Calendar, BCMath, COM, PCRE, Session, WDDX and XML support is built-in. You don't need to load any additional extensions in order to use these functions. and I have basic PHP scripts running I though making a call to mysql_connect would be pretty straight forward. The script I'm running is simply <?php echo mysql_connect ('localhost', 'webuser', 'BroWs1ng'); ?> where webuser@localhost has been granted select privileges on a test database. I receive the following error message: Fatal error: Call to undefined function mysql_connect() in C:\WebSpace\mysql_test.php on line 3 I was surprised to see mysql_connect was underfined given that the installation notes stated support for MySQL was built in from 4.0.5 onwards. So I went to the php.ini file in my windows directory and tried to manually load the mysql dll by uncommenting (removing the semi colon) the following line: ;extension=php_mysql.dll When I restart Apache I get the following error: PHP Startup: Unable to load dynamic library 'c:\PHP\ext\php_mysql.dll' - The specified module could not be found I then get an error window wanting to send a report then another pop up stating "The requested operation failed!" I tried uncommenting the dbase library instead and restarting the server worked and phpinfo in the additional modules section showed dbase as loaded. Any ideas? thanks in advance Chris
