You will laugh at me "download document" 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 = "info_check.exe";
$ file_dir = "/ public / www / download /";
IF (! file_exists ($ file_dir. $ file_name)) {// Check if the file exists
Echo "file can't find";
EXIT;
} else {
$ file = fopen ($ file_dir. $ file_name, "r"); // Open file
// Enter a file tag
Header ("Content-Type: Application / OcTet-Stream");
"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 = "info_check.exe";
$ FILE_DIR = "http://www.easycn.net/";
$ file = @ FOPEN ($ file_dir. $ file_name, "r");
IF ($ file) {
Echo "file can't find";
} else {
Header ("Content-Type: Application / OcTet-Stream");
Header ("Content-Disposition: attachment; filename =". $ File_name);
While (! Feof) {
Echo Fread ($ FILE, 50000);
}
Fclose ($ file);
}
This allows you to output a file directly with PHP.
