php 5.6.9 on Windows 7 x64 curl 不识别

php5.6.9 win7 64位下，出现Call to undefined function curl_init() 
百度了半天无果，最好还是翻墙后Google了一下解决问题~ 
常规的 extension=php_curl.dll 这种处理方法自不必说~

**将PHP文件夹下的 libeay32.dll 
libssh2.dll 
ssleay32.dll 
覆盖到Apache/bin目录下，然后重启Apache即可~~**

Upgrading to php 5.6.9 on Windows 7 x64 curl no longer is recognised. No errors on server start package just not available and didn’t show in phpinfo.php. deplister.exe was ok 
I fixed coping the following list files from php folder (in my case D:\xampp\php) 
libeay32.dll 
libssh2.dll 
ssleay32.dll 
to c:\xampp\apache\bin (or your apache\bin path), restart apache and works fine, apache’s libraries were outdated
