Question

我正在尝试使用php阅读电子邮件，我正在使用下面的代码，但它的错误Fatal error: Call to undefined function imap_open() in /testpage2/testmail.php on line 18任何人都可以指导我。谢谢

<?php
$codes = array("7bit","8bit","binary","base64","quoted-printable","other");
$stt = array("Text","Multipart","Message","Application","Audio","Image","Video","Other");

$pictures = 0;
$html = "";

# Connect to the mail server and grab headers from the mailbox

$mail = imap_open('{mail.xxxxxxxx.com:110/pop3}', 'xxxxxx@xxxxxxxx.com', 'xxxxxxxxx');
$headers = imap_headers($mail);

# loop through each email

for ($n=1; $n<=count($headers); $n++) {
        $html .=  "<h3>".$headers[$n-1]."</h3><br />";

# Read the email structure and decide if it's multipart or not

        $st = imap_fetchstructure($mail, $n);
        $multi = $st->parts;
        $nparts = count($multi);
        if ($nparts == 0) {
                $html .=  "* SINGLE part email<br>";
        } else{
                $html .=  "* MULTI part email<br>";
        }

# look at the main part of the email, and subparts if they're present

        for ($p=0; $p<=$nparts; $p++) {

Answer 1

您需要enable IMAP in PHP才能使用它。如果您执行phpinfo()，则可以确认是否已安装。

Answer 2

正如其他人所说启用或安装imap扩展名（例如ubuntu / debian中的php5-imap）。顺便说一句。看看Fetch，这是一个很好的面向OOP的库，用于处理IMAP。

Answer 3

如果您使用XAMPP启用php_imap.dll extension 转到XAMPP/php 更改php.ini file

;extension=php_imap.dll

要

 extension=php_imap.dll

Answer 4

您的服务器上没有安装PHP的IMAP模块。安装 php5-imap 。

参考：http://www.php.net/manual/en/imap.setup.php

Answer 5

检查服务器中是否已启用天气imap，如果未启用则表示启用它。如果未安装imap扩展名意味着安装并启用它，请检查此链接http://www.php.net/manual/en/imap.setup.php

Answer 6

如果您有 php 7+，请更新您的 php.ini 文件

取消注释

;extension=imap

到

extension=imap

如果您找不到 extension=imap，请手动将其添加到您的 php.ini 部分，只需搜索 ;extension

最后重启Apache

致命错误：调用未定义的函数imap_open（）
