I\'m stack here.
I want to create a file and i use title_input as file_name, but i have problem when create the file to specific folder.
Example:
You can always just encode the filename to make a valid filename and then decode the filename after you have read from it and this could be as simple as base64ing the filename before and after.
$filename = 'Multi purpose Day/Night Security';
// Raw filename
$filename = base64_encode($filename);
// Original filename
$filename = base64_decode($filename);
