当我使用xampp启动moodle 2.6.2时会出现appcrash问题

I am using

Moodle 2.6.2 (Build: 20140310), php 5.4.7, MySQL 5.5.27, Apache 2.4.3, XAMPP server version 1.8.1.

I am able to load the page 'localhost/xampp'.

When I try to launch 'localhost/moodle' then it throws the following error

Problem Event Name: APPCRASH
Application Name: httpd.exe
Application Version: 2.4.3.0
Fault Module Name: php5ts.dll
Fault Module Version: 5.4.7.0
...
...
...

Anybody has suggestion to resolve this 'appcrash' issue.

Check the PHP and server log files to see if they give you a specific error message.
