quoted_printable_decode()

(PHP 4, PHP 5, PHP 7)

将 quoted-printable 字符串转换为 8-bit 字符串

说明

该函数返回 quoted-printable 解码之后的 8-bit 字符串(参考» RFC2045 的6.7章节，而不是» RFC2821 的4.5.2章节，so additional periods are not stripped from the beginning of line)

该函数与 imap_qprint()函数十分相似，但是该函数不需要依赖 IMAP 模块。

参数

输入的字符串。

返回值

返回的 8-bit 二进制字符串。

I use a hack for this bug:
$str = str_replace("=\r\n", '', quoted_printable_encode($str));
if (strlen($str) > 73) {$str = substr($str,0,74)."=\n".substr($str,74);}

As soletan at toxa dot de reported, that function is very bad and does not provide valid enquoted printable strings. While using it I saw spam agents marking the emails as QP_EXCESS and sometimes the email client did not recognize the header at all; I really lost time :(. This is the new version (we use it in the Drake CMS core) that works seamlessly:
