I have installed php 5 on to my sever running IIS 6.0 and it works fine. I know that php 5 doesn't have built in support for mysql and I have followed instructions on the web to enable it but I am still having issues. When I try to load a page with the mysql_connect funtion I get: Fatal error: Call to undefined function mysql_connect() Here is what I have done to enable mysql support in php 5. in php.ini - located in the c:\windows directory extension_dir = "C:\PHP\ext" - this is the current extension directory ;extension=php_mssql.dll ;extension=php_msql.dll extension=php_mysql.dll extension=php_mysqli.dll ;extension=php_oci8.dll ;extension=php_openssl.dl I have copied php_mysql.dll and php_mysqli.dll to the c:\windows\system32 directory I have also added c:\php and c:\php\ext to the system path as well. I have restarted my machine and it still gives me the fatal error saying the mysql_connect funtion is undefined. Does anybody have any idea why this is still happening? Thanks in advanced.
