Solution to Call to undefined function curl_init () in php running

I downloaded a php program example simulating login to the discuz forum on the Internet. During the trial run, the error "Call to undefined function curl_init" is prompted, and no function is defined, that is, php does not support the curl_init function. Google finally solved the problem as follows:

Take php + apache in windows as an example.

First, open php. ini, find "extension = php_curl.dll", remove the comment ";", and restart apache.

If such problems still occur, first check php. which directory is the extension_dir value of ini? Check for php_curl.dll in that directory. If not, download php_curl.dll and copy libeay32.dll and ssleay32.dll in the php Directory to c: \ windows \ system32, restart apache. OK!

Running php In Ubuntu always prompts Call to undefined function curl_init () for no reason: php5-curl

CURL is a library for getting files from FTP, GOPHER, HTTP server.

PHP5 is an HTML-embedded scripting language. much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. the goal of the language is to allow web developers to write dinamically generated pages quickly. this version of PHP5 was built with the Suhosin patch.
