I have a website, where the user can write PHP/HTML code and save it to his computer. Everything is fine until the user types a slash (/).
The file saves into the client computer, but instead of saving the client code, it exports an PHP error (the file in the computer has a PHP code of an error). The file-saving code is the following:
$content = $_REQUEST['code']; //Get the code
$file = "file.php";
file_put_contents($file, $content); //Writes the content into a file
header('Content-type: text/plain');
header('Content-Disposition: attachment; filename=$file');
readfile(dirname(dirname($con)) . '/'.$file);
The error only happens when the client uses slashes. Any idea on why is this happening? )-:
EDIT:
This is one of those errors:
The code that i tried to export was the following:
/:
The thing that worries me, is that if I type exactly the same characters in different order (:/) then they export to my computer with no errors.
