HomeBackend DevelopmentPHP TutorialPHP date and time application 10: Convert seconds into the format 'day, hour, minute and second'

In the previous article "PHP date and time application nine: Get the start and end dates of a certain week in a certain year", I introduced you how to get the start and end dates of a certain week in a certain year. This article continues Let me introduce to you how to convert a number of seconds into a specific format of days, hours, minutes and seconds.

For example, how to convert 200000 seconds into a specific format of days, hours, minutes and seconds?

Do you have any ideas for implementation?

The following is an implementation method I gave for your reference:

The PHP code is as follows:

<?php

function convert_seconds($seconds)
{
    $dt1 = new DateTime("@0");
    $dt2 = new DateTime("@$seconds");
    return $dt1->diff($dt2)->format(&#39;%a 天, %h 时, %i 分 %s 秒&#39;);
}
echo convert_seconds(200000)."<br>";

The output result is:

PHP date and time application 10: Convert seconds into the format day, hour, minute and second

There is a class that everyone needs to understand here, which is the DateTime class. (Recommended article: "How to use the datetime class in php? Introduction to the usage of datetime in php")

DateTime update log is as follows:

PHP7.2.0版本:DateTime 的类常量现在定义在 DateTimeInterface 上。
PHP7.0.0版本:新增常量:DATE_RFC3339_EXTENDED 和 DateTime::RFC3339_EXTENDED。
PHP5.5.0版本:实现 DateTimeInterface 接口。
PHP5.4.24版本:COOKIE 格式从 2 位数字表示年份(RFC 850) 修改为 4 位数字表示年份(RFC 1036)。
PHP5.2.2版本:DateTime 对象进行比较操作(comparison operators)的时候 可以正常工作了。 在之前的版本中,当使用 == 进行相等比较的时候, 所有的 DateTime 对象都会被视为是相等的。

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
