Apache failed to start problem resolution error configured-resuming normal operations

Today I try this learning PHP environment to build.

Did not expect to install Apche Server 2.2 after the launch of the error, error log is as follows:

After searching online, the solution is as follows.

1 Add the PHP.ini directory to the environment variable path

2 new system Variable phprc= "php.ini directory"

3 If through the above two or not successful then a trick: the PHP installation directory under the Libmysql.dll file copy to Windows/system32 under

4 Copy Libmysql.dll to Apache/bin

I was successful after 124 steps:

The following error also occurs:

The version of PHP is inconsistent with your Apach version. Apache is not supported. Need to download and install PHP again. Download address: http://windows.php.net/download/
