quoted_printable_decode – PHP String Functions
The quoted_printable_decode() function decodes a quoted-printable string to an 8-bit string.
This function returns an 8-bit binary string corresponding to the decoded quoted printable string (according to » RFC2045, section 6.7, not » RFC2821, section 4.5.2, so additional periods are not stripped from the beginning of line).
It is same as imap_qprint(), except this one does not require the IMAP module to work.
