dl() in php5?

hi, i have to move a project from php4 to php5. no bigger issues so far, but now im stuck because the project uses some custom dll's for a key generator, and they have been included via dl("php_keygen.dll"), but if i try it via php.ini

extension=php_keygen.dll

Code (markup):

(yes, they are in the same folder as all the other loaded extensions)

i cant see anything in phpinfo() or extension_loaded().
any ideas what could be wrong here? are there any special requirements for php .dll's?

 

Are you on a Windows or UNIX server?

And also, did you restart Apache after the change?

 

IIS (version 5 imho) on windows 2000.
restarted the server after i adjusted the PATH on computer->properties->... and also restarted the IIS service; no difference. also mailed to to people who wrote the keygen dll if there are some depencies to other .dll's, but no reply yet :/

extension_dir = "C:/PHP/ext"

Code (markup):

and

extension=php_genkey.dll

Code (markup):

is that correct, or is it

extension_dir = "C:\PHP\ext"

Code (markup):

?

 

ah, nothing i can do. dll depend on some other dlls who run only under php4 - so i have to switch all projects back to from 5 to 4
