PHP添加新的.dll使Apache服务器无法启动

Question

I am trying to add an extension to my PHP. I have the file - libssh2.dll - in the appropriate directory (as listed in my php.ini file) and made sure the extension=libssh2.dll. I also copied the .dll file to system and system32 folders as other threads have suggested. When I try to start my Apache server I get the following windows error:

Apache HTTP Server has encountered a problem and needs to close. We are sorry for the inconvenience.

and Apache Monitor error:

The requested operation has failed!

I check the log to see this:

[Tue Jul 26 16:43:06 2011] [warn] pid file C:/Program Files/Apache/logs/httpd.pid overwritten -- Unclean shutdown of previous Apache run?

I have tried to go in this direction but am completely stumped at this point. Hoping someone out there can help me and so I can figure out what's wrong. Thanks in advance guys!

Cheers

Answer 1

I solved it by upgrading to 5.3. Somehow with the same settings it automagically worked. Closing the issue now.

I think that it is telling you that you need to remove just the previous pid file. Each time that you run apache a http.pid file is created in apache's bin folder. It contains the apache pid.
