PHP download files (hide real files) Sometimes we need to hide real files to prevent malicious downloads. we can use the following method (refer to the network, please inform us of infringement)


Reference content is as follows:

$ File_name = "example.exe ";

$ File_dir = "/public/www/download /";

If (! File_exists ($ file_dir. $ file_name) {// check whether the file exists

Echo "file not found ";

Exit;

} Else {

$ File = fopen ($ file_dir. $ file_name, "r"); // open the file

// Input 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 is a remote file, the original code will be slightly changed. The program is as follows:


Reference content is as follows:

$ File_name = "example.exe ";

$ File_dir = "http://back.zhizhi123.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 );

}

In this way, you can use PHP to directly output files.
