mailparse_determine_best_xfer_encoding()
(PECL mailparse >= 0.9.0)
Gets the best way of encoding
说明
mailparse_determine_best_xfer_encoding(resource $fp): string
Figures out the best way of encoding the content read from the given file pointer.
参数
- $fp
A valid file pointer, which must be seek-able.
返回值
Returns one of the character encodings supported by the mbstring module.
范例
Example #1 mailparse_determine_best_xfer_encoding() example
<?php $fp = fopen('somemail.eml', 'r'); echo 'Best encoding: ' . mailparse_determine_best_xfer_encoding($fp); ?>
以上例程的输出类似于:
Best encoding: 7bit
As far as I can tell, this only returns one of two strings: 'Quoted-Printable' or '7bit'
As of mailparse-2.1.5, it can return 7bit, 8bit, base64 and qprint. False on mbstring failure.
