php file download IE file name garbled Question

I have been using Chrome browser and no problem has been found. I used IE6 today and found that the file name was garbled when downloading the file, and the file name downloaded from Thunder under IE was also garbled. I checked online and said that I need to use urlencode to encode it in IE. I tried

header('Content-Disposition: attachment; filename='. rawurlencode($file_name); and the result was still garbled when I downloaded it. The php file itself is gbk/gb2312 encoded, so I first converted $file_name to utf-8 encoding and then urlencode

header('Content-Disposition: attachment; filename='. rawurlencode(iconv("GBK" ,"UTF-8",$file_name))); In this way, there is no problem in downloading using IE. Can urlencode only escape encoding for utf-8?

There is also the problem of obtaining the size of the remote file , the filesize function in PHP can only process local files. Processing remote files will fail and issue a warning, and the parameters passed in on the Windows platform must be gbk/gb2312 encoding. Using UTF-8 encoding will not be able to access the system. Resources.

I found four ways to get the size of remote files on the Internet. Thank you seniors for sharing. Record them:

Method 1: header

<?php get_headers($url,true); //返回结果 Array ( [0] => HTTP/1.1 200 OK [Date] => Sat, 29 May 2004 12:28:14 GMT [Server] => Apache/1.3.27 (Unix) (Red-Hat/Linux) [Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT [ETag] => "3f80f-1b6-3e1cb03b" [Accept-Ranges] => bytes [Content-Length] => 438 [Connection] => close [Content-Type] => text/html ) ?>

Here you can follow Content-Length directly obtains the size.

Method 2: curl

function remote_filesize($uri,$user=&#39;&#39;,$pw=&#39;&#39;) { // start output buffering ob_start(); // initialize curl with given uri $ch = curl_init($uri); // make sure we get the header curl_setopt($ch, CURLOPT_HEADER, 1); // make it a http HEAD request curl_setopt($ch, CURLOPT_NOBODY, 1); // if auth is needed, do it here if (!emptyempty($user) && !emptyempty($pw)) { $headers = array(&#39;Authorization: Basic &#39; . base64_encode($user.&#39;:&#39;.$pw)); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); } $okay = curl_exec($ch); curl_close($ch); // get the output buffer $head = ob_get_contents(); // clean the output buffer and return to previous // buffer settings ob_end_clean(); echo &#39;<br>head-->&#39;.$head.&#39;<----end <br>&#39;; // gets you the numeric value from the Content-Length // field in the http header $regex = &#39;/Content-Length:\s([0-9].+?)\s/&#39;; $count = preg_match($regex, $head, $matches); // if there was a Content-Length field, its value // will now be in $matches[1] if (isset($matches[1])) { $size = $matches[1]; } else { $size = &#39;unknown&#39;; } //$last=round($size/(1024*1024),3); //return $last.&#39; MB&#39;; return $size; } 方法三：fsock
function getFileSize($url) { $url = parse_url($url); if($fp = @fsockopen($url[&#39;host&#39;],emptyempty($url[&#39;port&#39;])?80:$url[&#39;port&#39;],$error)) { fputs($fp,"GET ".(emptyempty($url[&#39;path&#39;])?&#39;/&#39;:$url[&#39;path&#39;])." HTTP/1.1\r\n"); fputs($fp,"Host:$url[host]\r\n\r\n"); while(!feof($fp)) { $tmp = fgets($fp); if(trim($tmp) == &#39;&#39;) { break; } elseif(preg_match(&#39;/Content-Length:(.*)/si&#39;,$tmp,$arr)) { return trim($arr[1]); } } return null; } else { return null; } } 方法四：file_get_contents
$fCont = file_get_contents("http://www.cnmiss.cn/"); echo strlen($fCont)/1024;
