The problem that php5 cannot find php_curl.dll under Windows
Since Curl is used, the following error is prompted when setting up: unable to load dynamic library '….php_curl.dll'
My environment is Apache/2.2.14 (Win32) PHP/5.3.0. It stands to reason that the installation of php5 is very simple. Just specify extension_dir = "c:/php523/ext/", such as gd2, mysqli and There is no problem with mysql_dll, but php_curl.dll always prompts an error. Try modifying the PATH path and copy the DLL to /windows/system32/, but it still prompts that php_curl.dll cannot be found.
Finally, I finally found this sentence on php.net: Note to Win32 Users: In order to enable this module on a Windows environment, libeay32.dll and ssleay32.dll must be present in your PATH.
Find these two files in the php root directory, copy libeay32.dll and ssleay32.dll to /windows/system32/, and finally got it done. The following information appears in phpinfo:
cURL support enabled
cURL Information 7.19 .4
