Solution to Call to undefined function curl_init() when running PHP_PHP Tutorial

I downloaded a PHP program example from the Internet that simulates logging into the discuz forum. During the trial run, the error message "Call to undefined function curl_init" appeared. There is no defined function, that is, PHP has not yet turned on support for the curl_init function. After searching on Google, I finally solved it. The method is as follows:

Take php+apache under Windows as an example.

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

If this kind of problem still occurs, first check which directory the extension_dir value of php.ini is, and check whether there is php_curl.dll in that directory. If not, please download php_curl.dll, and then change the directory in the php directory. Copy libeay32.dll and ssleay32.dll to c:windowssystem32, restart apache, OK!

When running php under Ubuntu, it always prompts Call to undefined function curl_init(). The reason is not fixed: php5-curl

For curl-related content, please see: http://packages. ubuntu.com/zh-cn/intrepid/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 .

curl_init -- Initialize a CURL session

Description

int curl_init ([string url])

The curl_init() function will initialize a new session and return a CURL handle for use by the curl_setopt(), curl_exec(), and curl_close() functions. If the optional parameter is provided, the CURLOPT_URL option will be set to the value of this parameter. You can set it manually using the curl_setopt() function.
Example 1. Initialize a new CURL session and retrieve a web page

$ch = curl_init();

curl_setopt ($ch, CURLOPT_URL , "http://www.zend.com/");
curl_setopt ($ch, CURLOPT_HEADER, 0);

curl_exec ($ch);

curl_close ($ch );
?>
