php curl打开网页

function get_web_page( $url )

{

$options = array(

CURLOPT_RETURNTRANSFER => true,     // return web page 返回网页

CURLOPT_HEADER         => false,    // 不返回头信息

CURLOPT_FOLLOWLOCATION => true,     // follow redirects

CURLOPT_ENCODING       => "",       // handle all encodings

CURLOPT_USERAGENT      => "spider", // 设置UserAgent

CURLOPT_AUTOREFERER    => true,     // set referer on redirect

CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect 连接超时

CURLOPT_TIMEOUT        => 120,      // timeout on response 回复超时

CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects

);

$ch      = curl_init( $url );

curl_setopt_array( $ch, $options );

$content = curl_exec( $ch );

$err     = curl_errno( $ch );

$errmsg  = curl_error( $ch );

$header  = curl_getinfo( $ch );

curl_close( $ch );

$header['errno']   = $err;

$header['errmsg']  = $errmsg;

$header['content'] = $content;

return $header;

}

如果出现

Fatal error: Call to undefined function curl_init()  

检查php.ini,在windows的xampp里 extension=php_curl.dll是默认注释的，去掉前面的分号就好。
