Linuxphpcurl_errno ($ ch) is running on windows. running curl_errno ($ ch) on linux returns 1. what is the problem?
Curl_errno ($ ch)
CURLE_UNSUPPORTED_PROTOCOL (1 )? The URL you sent to libcurl uses a protocol not supported by this libcurl. The possible cause is that you do not use the compile-time option (it may be that the protocol string is misspelled or the protocol libcurl code is not specified ).

I also found that it may be the reason why ssl is not enabled. I opened the info on windows and compared it. this is the reason. Because I am generating a menu now, an https address will be sent. it should have a certificate for verification, and ssl needs to be enabled. it seems that I want to install openssl on the Internet, but I am not familiar with linux.
This problem has been solved. it is indeed because ssl is not enabled. thank you!
