导读：想知道什么是php mail()优先级类型.我读了这篇 question,我读了php手册, ?php $headers = "MIME-Version: 1.0n" ; $headers .= "Content-Type: text/html; charset="iso-8859-1"n"; $headers .= "X-Priority: 1 (Higuest)n"; $headers .= "X-MSMail-Pri

想知道什么是php mail()优先级类型.我读了这篇 question,我读了php手册,

<?php
    $headers = "MIME-Version: 1.0n" ;
    $headers .= "Content-Type: text/html; charset="iso-8859-1"n";
    $headers .= "X-Priority: 1 (Higuest)n";
    $headers .= "X-MSMail-Priority: Highn";
    $headers .= "Importance: Highn";
    $status   = mail($to,$subject,$message,$headers);
?>

但它没有解释我们可以使用的类型. X-Priority：1(Higuest)和X-MSMail-Priority：用于此的高两个不同的单词.我找到的优先级很少.例如：低,中,高,紧急,关键我们如何使用这种类型.

解决方法

值：1 =高,3 =正常,5 =低

您无需输入两行,请使用X-MSMail-Priority或X-Priority

Alternative to X-Priority,although X-Priority is preferred. “High”
corresponds to X-Priority: 1,“Normal” is the same as X-Priority: 3,
and “Low” is the same as “X-Priority: 5”. Including both X-Priority
and X-MSMailPriority in the same email header is OK,although it
probably best they agree.

Example:

either

X-MSMail-Priority: High

or

X-Priority: 1
