mailparse_determine_best_xfer_encoding — Gets the best way of encoding
Figures out the best way of encoding the content read from the given file pointer.
A valid file pointer, which must be seek-able.
Returns one of the character encodings supported by the mbstring module.
Beispiel #1 mailparse_determine_best_xfer_encoding() example
<?php
$fp = fopen('somemail.eml', 'r');
echo 'Best encoding: ' . mailparse_determine_best_xfer_encoding($fp);
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Best encoding: 7bit
As far as I can tell, this only returns one of two strings: 'Quoted-Printable' or '7bit'
