HELP...

My name is Salvatore Barbagallo and I'm trying to learn PHP using mSQL. I already installed my web server (Omni httpd) and the mSQL windows version and I'm using WIN NT 4.0. Plus, I downloaded the PHP3 .dll library and I saved it under my "D:" drive on the following path: d:\php3 but when I try to run the script reported below, I get an error at the line dl("d:\php3\php_msql1.dll"); (see script reported below) with the following error: Fatal error: Unable to load dynamic library 'd:\php3\php3_msql1.dll' The file php3_msql1.dll is under the directory d:\php3 so, I don't know why I get this error. Could you please help me in order to resolve this problem. I really appreciate any help. Tahnks. PHP SCRIPT <?php echo "Hi, I'm a PHP script!"; dl("d:\php3\php3_msql1.dll"); Msql_connect("localhost"); $database="salvo"; $result=msql($database,"insert into prova1 (var1,var2) values ('$ISSOA','$USER')"); ?>
