PHP file upload function implementation code_PHP tutorial

Personally, I think the idea of ​​uploading and downloading PHP files is almost the same. That is, there is an extra header statement in the code
The following is the detailed code. For reference only.
Entry file

Copy code The code is as follows:

enctype="multipart/form-data">
Filename:
" />

php write Processing files
if( empty($_GET['FileName'])){
echo'<script> alert("Illegal connection!"); location.replace (" ./fileload.html") </script>'; exit();
}
$file_name=$_GET['FileName'];//Get the file to be downloaded
if (!file_exists ($file_name)) { //Check if the file exists
echo "File not found";
exit;
} else {
$file = fopen( $file_name,"r"); // Open the file
// Enter the file tag
Header("Content-type: application/octet-stream"); ​​
//Header("Accept-Ranges: bytes");
/ /Header("Accept-Length: ".filesize( $file_name));
//Header("Content-Disposition: attachment; filename=" . $file_name);
// Output file content
echo fread($file,filesize( $file_name));
fclose($file);
exit();
}
?>

The above code I found it on the Internet, but it was not complete. After a period of debugging and modification, I finally realized the function. I was so excited that I shared it with everyone as soon as possible.
