這裡的下載,指的是 彈出下載提示框。

 

第一種:

?
1234567891011121314 <?php function downfile(){ $filename=realpath("resume.html"); //檔案名稱 $date=date("Ymd-H:i:m"); Header( "Content-type:  application/octet-stream ");  Header( "Accept-Ranges:  bytes "); Header( "Accept-Length: " .filesize($filename)); header( "Content-Disposition:  attachment;  filename= {$date}.doc");  echo file_get_contents($filename); readfile($filename); }downfile();?>

(推薦這種方法,親測可行,其他的沒測試)

?
123456789101112131415 <?php function downfile($fileurl){ ob_start();  $filename=$fileurl; $date=date("Ymd-H:i:m"); $size=readfile($filename); header( "Content-type:  application/octet-stream ");  header( "Accept-Ranges:  bytes ");  header( "Content-Disposition:  attachment;  filename= {$date}.doc");  header( "Accept-Length: " .$size);} $url="url地址"; downfile($url);?>

第二種:

?
123456789101112131415161718 <?php function downfile($fileurl){$filename=$fileurl;$file  fopen($filename, "rb"); Header( "Content-type:  application/octet-stream "); Header( "Accept-Ranges:  bytes "); Header( "Content-Disposition:  attachment;  filename= 4.doc"); $contents = "";while (!feof($file)) { $contents .= fread($file, 8192);}echo $contents;fclose($file); }$url="url地址";downfile($url);?>

PHP實現下載檔案的兩種方法。分享下,有用到的朋友看看哦。

方法一:

?
1234567891011121314151617 <?php/*** 下載檔案* header函數**/header(‘Content-Description: File Transfer‘); header(‘Content-Type: application/octet-stream‘);header(‘Content-Disposition: attachment; filename=‘.basename($filepath));header(‘Content-Transfer-Encoding: binary‘);header(‘Expires: 0′);header(‘Cache-Control: must-revalidate, post-check=0, pre-check=0′);header(‘Pragma: public‘);header(‘Content-Length: ‘ . filesize($filepath));readfile($file_path);?>

瞭解php中header函數的用法。

方法二:

?
12345678910 <?php//檔案下載//readfile$fileinfo = pathinfo($filename);header(‘Content-type: application/x-‘.$fileinfo[‘extension‘]);header(‘Content-Disposition: attachment; filename=‘.$fileinfo[‘basename‘]);header(‘Content-Length: ‘.filesize($filename));readfile($thefile);exit();?>
