关于安装php扩展php_curl 出现的提示错误，导致php_curl无法安装
apache 错误日志：
PHP Warning: PHP Startup: in Unknown on line 0
网上找了很多，依着做都不行。PHP手册里其实已经有处理方法，地址：http://php.net/manual/zh/curl.installation.php。如下：
I had to also also copy libssh2.dll into my Apache24 folder for this to work with my PHP 5.6.2 installation. So altogether I had to do the following: Move to Windows\system32 folder: libssh2.dll, php_curl.dll, ssleay32.dll, libeay32.dll Move to Apache24\bin folder libssh2.dll Uncomment extension=php_curl.dll
解释：
复制 libssh2.dll, php_curl.dll, ssleay32.dll, libeay32.dll 到 Windows\system32 目录 复制 libssh2.dll 到apache的bin目录
加载 扩展 extension=php_curl.dll.
