我正在尝试使用quoted_printable_encode()和[quoted_priatble_decode(),但问题是我的服务器正在运行PHP4,根据PHP 文档,quoted_printable_encode() 仅适用于PHP 5 >= 5.3.0。有谁知道黑客或解决方法,所以我可以利用编码功能

根据文档,您可以使用imap_8bit,但是您应该真正考虑升级到 php5。它已经存在了6年多!

我不能感谢大家的支持和帮助。我完全同意我们应该升级到 PHP5 - 但这是针对我工作的大公司,而且正如你们中的许多人所知,有些事情应该发生,但不应该或不能。反正我只是个实习生,所以我会照他们说的做=)
我想到了 -
function quoted_printable_encode($input, $line_max = 75) { // Quoted_printable_encode that works with php 4.x
$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);
$linebreak = "=0D=0A=\r\n";
/* the linebreak also counts as characters in the mime_qp_long_line
* rule of spam-assassin */
$line_max = $line_max - strlen($linebreak);
$escape = "=";
$output = "";
$cur_conv_line = "";
$length = 0;
$whitespace_pos = 0;
$addtl_chars = 0;
// iterate lines
for ($j=0; $j<count($lines); $j++) {
$line = $lines[$j];
$linlen = strlen($line);
// iterate chars
for ($i = 0; $i < $linlen; $i++) {
$c = substr($line, $i, 1);
$dec = ord($c);
$length++;
if ($dec == 32) {
// space occurring at end of line, need to encode
if (($i == ($linlen - 1))) {
$c = "=20";
$length += 2;
}
$addtl_chars = 0;
$whitespace_pos = $i;
} elseif ( ($dec == 61) || ($dec < 32 ) || ($dec > 126) ) {
$h2 = floor($dec/16); $h1 = floor($dec%16);
$c = $escape . $hex["$h2"] . $hex["$h1"];
$length += 2;
$addtl_chars += 2;
}
// length for wordwrap exceeded, get a newline into the text
if ($length >= $line_max) {
$cur_conv_line .= $c;
// read only up to the whitespace for the current line
$whitesp_diff = $i - $whitespace_pos + $addtl_chars;
/* the text after the whitespace will have to be read
* again ( + any additional characters that came into
* existence as a result of the encoding process after the whitespace)
*
* Also, do not start at 0, if there was *no* whitespace in
* the whole line */
if (($i + $addtl_chars) > $whitesp_diff) {
$output .= substr($cur_conv_line, 0, (strlen($cur_conv_line) -
$whitesp_diff)) . $linebreak;
$i = $i - $whitesp_diff + $addtl_chars;
} else {
$output .= $cur_conv_line . $linebreak;
}
$cur_conv_line = "";
$length = 0;
$whitespace_pos = 0;
} else {
// length for wordwrap not reached, continue reading
$cur_conv_line .= $c;
}
} // end of for
$length = 0;
$whitespace_pos = 0;
$output .= $cur_conv_line;
$cur_conv_line = "";
if ($j<=count($lines)-1) {
$output .= $linebreak;
}
} // end for
return trim($output);
} // end quoted_printable_encode
使它工作。在你们发布之后我碰巧回到这里,所以很遗憾我没有测试你们的解决方案,但上面的功能非常完美!
再次感谢大家!

public function quoted_printable($mesg){
$orders = unpack("C*", $mesg);
unset($mesg);
array_filter($orders, array($this, 'cb_qp'));
return implode($orders);
}
// Quoted-Printable Callback
private function cb_qp(&$byte){
$byte = ($byte > 126 || $byte == 61 || $byte == 37) ? sprintf('=%X', $byte) : pack("C", $byte);
}

您是否安装了 IMAP 模块?用什么imap_8bit()
代替呢?

最好的办法是升级到 PHP 5。4 已经 死了。
如果这真的,真的不是一个选项,您链接到的手册页有一些替代方案(imap_8bit()
以及用户贡献的注释中的一些替代实现)。
