复制代码 代码如下:
function getFileSize($url){
$url = parse_url($url);
if($fp = @fsockopen($url['host'],empty($url['port'])?80:$url['port'],$error)){
fputs($fp,"GET ".(empty($url['path'])?'/':$url['path'])." HTTP/1.1\r\n");
fputs($fp,"Host:$url[host]\r\n\r\n");
while(!feof($fp)){
$tmp = fgets($fp);
if(trim($tmp) == ''){
break;
}else if(preg_match('/Content-Length:(.*)/si',$tmp,$arr)){
return trim($arr[1]);
}
}
return null;
}else{
return null;
}
}
//调用方法
echo getFileSize("http://www.bitsCN.com/images/logo.gif")
?>
大家运行后，大小应该是4445字节。
