为什么centos curl版本与php curl版本不同

I updated centos7 curl and now the version is 7.65, then I rebuilt php7 and set --with-curl=/usr/bin/curl. When I finished curl_version() still shows 7.20. Why is that?

I use guzzle to request a web which need http_version 2.0, so I have to upgrade php curl. Hope someone helps me, thanks a lot!

You have to update libcurl and use the installation path as compile option --with-curl=/path/to/libcurl

To do so follow the next steps:

As described here:

1. install curl-config
2. find the path of libcurl with curl-config --cflags
3. use curl-config --version to determine the libcurl version
4. if it is not the version you expect, rebuild curl with the --includedir option
5. rebuild php with the option --with-curl=/path/to/libcurl
