Question

I’ve updated php.ini and moved php_mysql.dll as explained in steps 6 and 8 here.

I get this error…

Fatal error: Call to undefined function mysql_connect() in C:\inetpub...

MySQL doesn’t show up in my phpinfo; report.

---

I’ve updated the c:\Windows\php.ini file from

; Directory in which the loadable extensions (modules) reside.   extension_dir = './'

to

; Directory in which the loadable extensions (modules) reside.   extension_dir = '.;c:\Windows\System32'

Result: no change.

---

I changed the php.ini value of extension_dir thusly:

extension_dir = 'C:\Windows\System32'

Result: much more in the phpinfo; report, but MySQL still isn’t working.

---

I copied the file libmysql.dll from folder C:\php to folders C:\Windows\System32 and C:\Windows

Result: no change.

---

I stopped and restarted IIS.

Result: new, different errors instead!

Warning: mysql_connect() [function.mysql-connect]: Access denied for   user '...'@'localhost' (using password: YES) in C:\inetpub\... error in query.

Fatal error: Call to a member function RecordCount() on a non-object   in C:\inetpub\...

I found several .php files in the website where I had to set variables:

$db_user   $db_pass

Result: The site works!

Answer 1

As the others say these two values in php.ini are crucial.

I have the following in my php.ini: note the trailing slash – not sure if it is needed – but it does work.

extension_dir = 'H:\apps\php\ext\' extension=php_mysql.dll 

Also it is worth ensuring that you only have one copy of php.ini on your machine – I’ve had problems with this where I’ve been editting a php.ini file which php isn’t using and getting very frustrated until I realised.

Also if php is running as a module within apache you will need to restart the apache server to pickup the changes. Wise to do this in anycase if you’re not sure.

a ‘php -m’ from the cmd prompt will show you the modules that are loaded from the ini file.
