If you do not have access to imap_* and do not want to use
»$message = chunk_split( base64_encode($message) );«
because you want to be able to read the »source« of your mails, you might want to try this:
(any suggestions very welcome!)
function qp_enc($input = "quoted-printable encoding test string", $line_max = 76) {
$hex =
array('0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F');
$lines = preg_split("/(?:\r\n|\r|\n)/", $input);
$eol = "\r\n";
$escape = "=";
$output = "";
while( list(, $line) = each($lines) ) {
//$line = rtrim($line); // remove trailing white space -> no =20\r\n necessary
$linlen = strlen($line);
$newline = "";
for($i = 0; $i < $linlen; $i++) {
$c = substr($line, $i, 1);
$dec = ord($c);
if ( ($dec == 32) && ($i == ($linlen - 1)) ) { // convert space at eol only
$c = "=20";
} elseif ( ($dec == 61) || ($dec < 32 ) || ($dec > 126) ) { // always encode
"\t", which is *not* required
$h2 = floor($dec/16); $h1 = floor($dec%16);
$c = $escape.$hex["$h2"].$hex["$h1"];
}
if ( (strlen($newline) + strlen($c)) >= $line_max ) { // CRLF is not counted
$output .= $newline.$escape.$eol; // soft line break; " =\r\n" is okay
$newline = "";
}
$newline .= $c;
} // end of for
$output .= $newline.$eol;
}
return trim($output);
}
$eight_bit = "\xA7 \xC4 \xD6 \xDC \xE4 \xF6 \xFC \xDF = xxx yyy
zzz \r\n"

print $eight_bit."\r\n---------------\r\n";
