php - 如何使用安全的 POP3 服务器覆盖 imap_timeout 功能的 php.ini 超时

Question

PHP IMAP 库没有内置方法来更改安全 pop3 连接的 imap_timeout 函数。我正在寻求构建此功能，以便我可以将安全 pop3 服务器的连接超时设置为 1 秒，但我只是不确定从哪里开始学习如何在 PHP 函数中覆盖 php.ini 命令。有任何想法吗？

imap_timeout(1, ) works fine for pop3 connections, but apparently not for pop3s (ssl, port 995) connections, where the default socket timeout still applies. This applies to php 4.3.10, not tested on other versions.

We looked into the source to find out what this function actually does and how to use it. The function overrides the default_socket_timeout setting from your php.ini file

You can retrieve the current timeout length for each timeout type by calling the function as:

imap_timeout(timeout_type); or imap_timeout(timeout_type,-1);

You can set the timeout length for any of the timeout types by setting the timeout value to a number of seconds.

imap_timeout(timeout_type,);

The timeout types are as follows:

1: Open 2: Read 3: Write 4: Close

It does not appear that the close type has been implemented.

使用default_socket_timeout

这里是覆盖默认配置的小演示。

ini_set('default_socket_timeout', 2);
// your socket based code here

// restore to the default socket timeout
ini_restore('default_socket_timeout');
