$img_dst = imagecreatetruecolor ( $w_dst, $h_dst ) // resample $img_src = imagecreatefrompng ( $file_src )

$img_src = imagecreatefromjpeg ( $file_src ) $img_src = imagecreatefromgif ( $file_src ) Public function manage_single_file ( string $input_name, string $folder_to_move, array $mime_allowed =, bool $return_json = true ) * bol => $return_json = se true retorna um objeto json * arr => $mime_allowed = mime types permitidos no processo de upload * str => $folder_to_move = nome da pasta em que o arquivo será salvo $upload_info = infos sobre os arquivos enviados You may have other mechanisms for verifying a file's extension, such as a preg_match on the whole name, using something like '/\.(gif|jpg|jpeg|png|bmp)$/i' (more can, of course, be added if you so desire) for the most common types of images found on the web.įor blindly guaranteeing an uploaded file will be uniquely named, this seems like a fantastic way to go. Then just piece it together in a string accordingly by stepping through the array (don't forget to add those dots back to where they were!), appending a guaranteed unique string of characters (or enumerate it like you were doing, keeping track via a loop), and finally tacking on the file extension. That's easy enough to handle - just explode() the file name and hope that the last element in the array it gives you is the file extension (you can always validate it if you're so inclined). Another wrench in the gears: a file can have dots in the filename. The best bet to me would be parsing the uploaded file's name ($_FILES) based on the presence of dots. Check out for a good reference of file extensions. For example, a JPEG file can be denoted by *.jpg (and others), but it can also have *.jpeg as a valid extension. However, it is worth noting that there are valid, registered file extensions that are longer than 3 characters. That function will work fine for files with a 3-character file extension. cgiĭo not forget this steps for your project protection. htaccess to stop working some scripts as in example php file in your upload path.ĪddHandler cgi-script.
