Identify a file via MIME type and file signature detection.

file-identifier's Issues

Multiple File Upload

I like it, I tried various filetypes the outputs were different. I even tried to fool your script and change the extension of an EXE file to a PNG file, and $r['fileinfo'] still returned "EXE (MZ: DOS / Windows)".

I'm having problems when I read from multiple [type="file"] inputs. I had to split $r['mimeinfo'] to just return the mimetype:

$fID = new FileIdentifier( $_FILES[ 'file' ][ 'tmp_name' ][ $key ] );
$IDr = $fID->getResult();
if ( $IDr ) {
  $mimeType = end( explode( ': ', $IDr[ 'mimeinfo' ] ) );
} else {
  print( json_encode( array( 'status' => 'danger', 'alertMsg' => 'Cannot detect signature for file: ' . $_FILES[ 'uploadimg' ][ 'name' ][ $key ], 'code' => 0 ) ) );
  exit();
}

It says the first file (presumably) because of having [$key] is invalid, even though when I tested it as a single file upload validating as an image, it came back valid.

if ( $mimeType !== 'image/jpeg' || $mimeType !== 'image/png' ) {
  // I've tried != and && in various combinations, still detects a real png image invalid.
  print( json_encode( array( 'status' => 'danger', 'alertMsg' => $_FILES[ 'uploadimg' ][ 'name' ][ $key ] . ' is not a true image', 'code' => 0 ) ) );
  exit();
}

And yes, I have this in a foreach() loop, the first thing I'm doing is making sure if the file is a PNG/JPEG/JPG, your script is "the nosy sibling" asking "Are you really?"
