折腾了半天百思不得其解，末了索性把php5.6、apache2.4以及对应的svn_mod，都升级到最新，创造仍旧不好用，但是error.log报错了：
PHP Warning: PHP Startup: Unable to load dynamic library 'D:/services/web/php56/ext/php_curl.dll' - \xef\xbf\xbd\xd2\xb2\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xd6\xb8\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xc4\xb3\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\r\n in Unknown on line 0

写道
Make sure to have your apache SSH dlls loading correctly. On a fresh install I had to download and load into my apache bin directory the following dll \"大众libssh2.dll\"大众
After ssl dll was loaded cURL was able to load with no issues.
You can download it from the link below:
http://windows.php.net/downloads/pecl/releases/ssh2/0.12/
下载php_ssh2-0.12-5.5-ts-vc11-x64.zip之后，试了一下这个libssh2.dll要放入php目录的lib下面，再启动apache curl事情正常！
话说nginx+fastcgi的模式仍旧是生产环境php运行的首选模式，没有了程序之间的相互依赖问题还是会少很多而且更随意马虎办理。
