I'm trying to decode a base64 string and write it to a file:
<?php
// requires php5
define('UPLOAD_DIR', '/images/');
$img = $_POST['img'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = UPLOAD_DIR . uniqid() . '.png';
$success = file_put_contents($file, $data);
print $success ? $file : 'Unable to save the file.';
?>
But the server gives this error message:
403 Forbidden
You don't have permission to access testupload.php on this server
I have set all permissons for the php file and the images directory, so I don't understand why I get this error.
When I put the decoded string of image directly inside the $img variable, it works and it creates the file under the images folder... But when I try to post the decoded string it doesn't work.
How can I solve this?
NOTE : when we try to send decoded string of image it may contain some virus or something like that from hackers ... i contact with my host providers and they say if you want we can turn of the modsecurity but its really unsafe way to do ... so what i have to do with this situation?
