PHP100 tutorial version 2012: PHP5.4 Apache Mysql configuration and multi-site configuration


This video. As a result, I couldn't have done that simple process three times! What's going on? I use winXP!
!
Add LoadModule php5_module "c:/www/php54/php5apache2_2.dll" and restart apache to report an error!
If this parameter is not added, apache runs normally!
You can't explain it! Is the version too new or a system problem? (The instructor is win7 .)

------ Solution --------------------
It has nothing to do with the system, it has something to do with the php version, and it has something to do with the tutorial...

For the effect, we can even get 5.4, php100 ....
This is a release candidate-do not use it in production !.


Install this.

------ Solution --------------------
Check whether c:/www/php54/php5apache2_2.dll exists.
