php How to download files, php file download the correct method

Check if the form is complete ... if ($form _completed) { Header ("Location:http://www.myweb.com/download/info_check.exe"); Exit } ?> Or: Start Download file Copy Code The ID is used here to receive the number of the file to download, and then "Redirect" the way to connect to the actual URL. For security reasons, do not let users directly copy the URL to download the file, it is recommended to use PHP directly read the actual file and then download. Code: $file _name = "Info_check.exe"; $file _dir = "/public/www/download/"; if (!file_exists ($file _dir. $file _name)) {//check if file exists echo "File not found"; Exit } else { $file = fopen ($file _dir. $file _name, "R"); Open File Input File Label Header ("Content-type:application/octet-stream"); Header ("Accept-ranges:bytes"); Header ("Accept-length:". FileSize ($file _dir. $file _name)); Header ("content-disposition:attachment; Filename= ". $file _name); Output file contents Echo fread ($file, FileSize ($file _dir. $file _name)); Fclose ($file); Exit;} ?> Copy Code If the file path is "http" or "FTP" URL, then the source code will change a little, the program is as follows: $file _name = "Info_check.exe"; $file _dir = "http://www.jincai123.com/"; $file = @ fopen ($file _dir. $file _name, "R"); if (! $file) { echo "File not found"; } else { Header ("Content-type:application/octet-stream"); Header ("content-disposition:attachment; Filename= ". $file _name); while (!feof ($file)) { Echo fread ($file, 50000); } Fclose ($file); } ?> Copy Code Using the above code, you can directly output files in PHP.
