You may laugh at me "Download Document" is so simple to say? Of course, it is not as simple as it is. For example, if you want customers to fill a form, you can download a file, you must use the "redirect" method, first check if the form has been completed and complete, then refer to the file Such a customer can download, but if you want to be an e-commerce website about "online shopping", consider security issues, you don't want the user to copy the URL to download the file, I suggest you read the actual file directly using the PHP and then download it. Method is done. The procedure is as follows:
$ file_name = "tianhys.exee"; $ file_dir = "/ public / www / download /"; if (! file_exists ($ file_dir. $ file_name))) {// Check if the file has an echo "file Can't find"; exit } Else {$ file = fopen ($ file_dir. $ File_name, "r"); // Open file // Enter file tag header ("Content-type: Application / OcTet-stream); Header (" Accept-Ranges : Bytes "); Header (" Accept-length: ".filesize ($ file_dir. $ file_name); Header (" Content-Disposition: attachment; filename = ". $ file_name); // Output file content echo fread ($ File, FileSize ($ file_dir. $ file_name); fclose ($ file); exit;}
If the file path is "http" or "FTP" URL, the source code will have a little change, the program is as follows:
$ file_name = "tianhys.exe"; $ file_dir = "http://www.tianhys.org/"; $ file = @ fopen ($ file_dir. $ file_name, "r"); if (! $ file) {echo "File";} else {header ("Content-type: Application / OcTet-stream); Header (" Content-Disposition: attachment; filename = "; $ file_name); while (! Feof ($ file) ) {Echo Fread ($ FILE, 50000);} fclose ($ file);}
This allows you to output a file directly with PHP.
