curl下载文件得到header和body

function curl_get_file_contents($URL) $user_agent = Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; 4399Box.560; .NET4.0C; .NET4.0E); $c = curl_init(); curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); curl_setopt($c, CURLOPT_HEA

function curl_get_file_contents($URL){
$user_agent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; 4399Box.560; .NET4.0C; .NET4.0E)";
$c = curl_init();
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_HEADER, 1);
curl_setopt($c, CURLOPT_USERAGENT, $user_agent);
curl_setopt($c, CURLOPT_URL, $URL);
$response = curl_exec($c);
$header_size = curl_getinfo($c, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);
curl_close($c);
if ($body) {
return array($header, $body);}
else {return FALSE;}
}

附带昆爷建议直接得到header内容：

$c = curl_init();
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_USERAGENT, $user_agent);
curl_setopt($c, CURLOPT_URL, $url);
$response = curl_exec($c);
$header = curl_getinfo($c);
