W takich dniach, jak ten, nie żałuję, że wykupiłem abonament. Korzystam z porad na tych stronach nawet kilkanaście razy w tygodniu i dzięki nim prace nad stronami dla klientów idą mi o wiele szybciej, a strony wyglądają bardziej profesjonalnie. Nie wiem, jak mogłem wcześniej pracować bez dostępu do porad w tym serwisie!

quoted_printable_decode (PHP 3 >= 3.0.6, PHP 4, PHP 5) quoted_printable_decode --
Convert a quoted-printable string to an 8 bit string
Descriptionstring quoted_printable_decode ( string str )
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).
This function is similar to
imap_qprint(), except this one does not
require the IMAP module to work.

As the two digit hexadecimal representation SHOULD be in uppercase you want to use "=%02X" (uppercase X) instead of "=%02x" as the first argument to sprintf().

This function appeared twice already and in both versions it's got error in rule replacing chunk_split, because it misses the last line in encoded text if it's shorter than 73 characters.
My solution (got rid of replace_callback)
<?
function quoted_printable_encode( $sString ) {
$sString = preg_replace( '/[^\x21-\x3C\x3E-\x7E\x09\x20]/e', 'sprintf( "=%02x", ord ( "$0" ) ) ;', $sString );
preg_match_all( '/.{1,73}([^=]{0,3})?/', $sString, $aMatch );
return implode( '=' . CR, $aMatch[0] );
}
?>

Previous comment has a bug: encoding of short test does not work because of incorrect usage of preg_match_all(). Have somebody read it at all? :-)
Correct version (seems), with additional imap_8bit() function emulation:
if (!function_exists('imap_8bit')) {
function imap_8bit($text) {
return quoted_printable_encode($text);
}
}
function quoted_printable_encode_character ( $matches ) {
$character = $matches[0];
return sprintf ( '=%02x', ord ( $character ) );
}
// based on http://www.freesoft.org/CIE/RFC/1521/6.htm
function quoted_printable_encode ( $string ) {
// rule #2, #3 (leaves space and tab characters in tact)
$string = preg_replace_callback (
'/[^\x21-\x3C\x3E-\x7E\x09\x20]/',
'quoted_printable_encode_character',
$string
);
$newline = "=\r\n"; // '=' + CRLF (rule #4)
// make sure the splitting of lines does not interfere with escaped characters
// (chunk_split fails here)
$string = preg_replace ( '/(.{73}[^=]{0,3})/', '$1'.$newline, $string);
return $string;
}

A easier, improved way of encoding for quoted-printable transfer:
------
function quoted_printable_encode_character ( $matches ) {
$character = end ( $matches );
return sprintf ( '=%02x', ord ( $character ) );
}
// based on http://www.freesoft.org/CIE/RFC/1521/6.htm
function quoted_printable_encode ( $string ) {
// rule #2, #3 (leaves space and tab characters in tact)
$string = preg_replace_callback (
'/[^\x21-\x3C\x3E-\x7E\x09\x20]/',
'quoted_printable_encode_character',
$string
);
$newline = "=\r\n"; // '=' + CRLF (rule #4)
// make sure the splitting of lines does not interfere with escaped characters
// (chunk_split fails here)
preg_match_all ( '/.{73}([^=]{0,3})/', $string, $match ); // Rule #1
return implode ( $newline, $match[0] );
}

i have found a bug in pob at medienrecht dot NOSPAM dot org
's qp_enc function. in quoted printable messages need to convert the first pont in the lines too...
here is the fixed code:
function qp_enc( $input = "", $line_max = 76, $space_conv = false ) {
$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 ( ( $i == 0 ) && ( $dec == 46 ) ) { //
convert first point in the line into =2E
$c = "=2E";
}
if ( $dec == 32 ) {
if ( $i == ( $linlen - 1 ) ) { // convert
space at eol only
$c = "=20";
} else if ( $space_conv ) {
$c = "=20";
}
} elseif ( ($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 = "";
// check if newline first character will
be point or not
if ( $dec == 46 ) {
$c = "=2E";
}
}
$newline .= $c;
} // end of for
$output .= $newline.$eol;
} // end of while
return trim($output);
}

Sorry, above I mixed up QP-Decode and UrlDecode, the example I gave above is in fact UrlDecode:
function UrlDecode($string) {
return preg_replace("/%([0-9A-Fa-f]{2})/e", "chr(hexdec('\\1'))", $string);
}
f.e. replaces '%3F' with '?'
Quoted-printable would be:
function qp_decode($string) {
return preg_replace("/=([0-9A-F]{2})/e", "chr(hexdec('\\1'))", $string);
}
f.e. replaces '=20' with ' '
