Libcurl cannot find libcurl.so.3 solution after upgrade _php tutorial

This article today to introduce you to a Libcurl upgrade can not find libcurl.so.3 solution to the law, I hope to help you friends.

The system is Libcurl version 7.19, the compiled dynamic library is libcurl.so.4

Its own program is compiled in the version of Libcurl 7.15, with the version of Libcurl.so.3, to do the following soft link:
Depending on whether you are using a 32-bit system or a 64-bit system, do the following:

The code is as follows	Copy Code
Cd/usr/lib or cd/usr/lib64 Ln-s libcurl.so.4 libcurl.so.3

Libcurl main function is to use different protocols to connect and communicate with different servers-that is, quite encapsulated sockphp support Libcurl (allowing you to connect and communicate different servers with different protocols). , Libcurl currently supports HTTP, HTTPS, FTP, Gopher, Telnet, dict, file, and LDAP protocols. Libcurl also supports HTTPS certificate authorization, HTTP POST, HTTP PUT, FTP upload (of course you can also use PHP's FTP extension), HTTP basic form uploads, proxies, cookies, and user authentication.

Give me a simple code example:
Description
1. Key in the CURL_EASY_SETOPT function set option, you can set a number of options such as Ftp,http,get,post, depending on the use of the settings.

2. The retrieved data needs to be judged, such as the HTTP download file, if the file does not exist, it needs to be processed. Because writer is able to fill buf 404 Not Found and other Web content, this content can not be used as a file content, so you need to judge the HTTP Web return code, to judge.

3. I have a problem, I want to get the name of filename on the server, verbose debugging has returned, but I getinfo in the time, tried a lot of options, but did not find the real server file name option, if you have to know the trouble to tell me, thank you!

The code is as follows

Copy Code
