php运行出现Call to undefined function curl

在Ubuntu 下运行php，总是提示Call to undefined function curl_init()，原因没有安转：php5-curl

与curl相关的内容见：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 -- 初始化一个CURL会话

描述 　

int curl_init ([string url]) 　

curl_init()函数将初始化一个新的会话，返回一个CURL句柄供curl_setopt(), curl_exec(),和 curl_close() 函数使用。如果可选参数被提供，那么CURLOPT_URL选项将被设置成这个参数的值。你可以使用curl_setopt()函数人工设置。
例 1. 初始化一个新的CURL会话，且取回一个网页

$ch = curl_init();

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

curl_exec ($ch);

curl_close ($ch);
?>
