I followed the online tutorial and wrote a small example of cURL. When I executed it in the apache environment, there was no response at all. But when I put it in the IIS environment, it was ok. I feel that the problem must be with the dynamic link library because php_curl in the configuration file. The dll has been opened and is ok on iis;
I found some solutions online:
-----------------------------
Set [environment variables]: phpext, PHPRC; invalid
Put php_curl.dll under apache/bin; invalid
I checked that there are also these two libeay32.dll
, <span style="color: #0000ff;"><strong>ssleay32.dll</strong></span> files in the apache/bin directory; no problem
I finally tried it, put the libssh2.dll in the current php root directory into the apache/bin directory, restarted apache, OK, finally saw the curl in phpinfo Once the module information is obtained, the program can naturally run.
