Installation

To use PHP’s cURL support you must also compile PHP
–with-curl[=DIR] where
DIR is the location of the directory containing the lib and include
directories. In the include directory
there should be a folder named curl
which should contain the easy.h and
curl.h files. There should be a file
named libcurl.a located in the
lib directory. Before PHP 5.5.0 it was
possible to configure PHP to use cURL for URL streams
–with-curlwrappers .

Note: Note to Win32
Users
In order to enable this module on a Windows
environment, libeay32.dll and
ssleay32.dll, or, as of OpenSSL 1.1
libcrypto-*.dll and libssl-*.dll, must be present in your PATH. Also libssh2.dll
must be present in your PATH.
You don’t need libcurl.dll from the cURL site.
