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。
