我今天遇到了一个奇怪的问题。我在发送电子邮件时使用的是Codeigniter Framework。有时,如果电子邮件主题很长,则单词会中断。例如,我的主题是:
This is a notification form test
但在发送的邮件中显示如下:
This is a notification form t est
正如您所见,test
现在是t est
。我搜索并发现了这个功能:
private function _prep_q_encoding($str, $from = FALSE)
{
$str = str_replace(array("\r", "\n"), array('', ''), $str);
// Line length must not exceed 76 characters, so we adjust for
// a space, 7 extra characters =??Q??=, and the charset that we will add to each line
$limit = 75 - 7 - strlen($this->charset);
// these special characters must be converted too
$convert = array('_', '=', '?');
if ($from === TRUE)
{
$convert[] = ',';
$convert[] = ';';
}
$output = '';
$temp = '';
for ($i = 0, $length = strlen($str); $i < $length; $i++)
{
// Grab the next character
$char = substr($str, $i, 1);
$ascii = ord($char);
// convert ALL non-printable ASCII characters and our specials
if ($ascii < 32 OR $ascii > 126 OR in_array($char, $convert))
{
$char = '='.dechex($ascii);
}
// handle regular spaces a bit more compactly than =20
if ($ascii == 32)
{
$char = '_';
}
// If we're at the character limit, add the line to the output,
// reset our temp variable, and keep on chuggin'
if ((strlen($temp) + strlen($char)) >= $limit)
{
$output .= $temp.$this->crlf;
$temp = '';
}
// Add the character to our temporary line
$temp .= $char;
}
$str = $output.$temp;
// wrap each line with the shebang, charset, and transfer encoding
// the preceding space on successive lines is required for header "folding"
$str = trim(preg_replace('/^(.*)$/m', ' =?'.$this->charset.'?Q?$1?=', $str));
return $str;
}
来自
public function subject($subject)
{
$subject = $this->_prep_q_encoding($subject);
$this->_set_header('Subject', $subject);
return $this;
}
在第一个函数中它说:
// Line length must not exceed 76 characters
这就是问题所在。如何在不编辑基本功能的情况下为电子邮件添加更长的主题?什么是支持更长篇幅的主题而不打破单词的最佳方法?请提前帮助,谢谢。

在您的电子邮件撰写配置中: $config['wrapchars'] = 100;
以增加限制,同时写下: $config['wordwrap'] = TRUE;
来换行。希望它有所帮助。
