How to convert timestamp to time format in php and jQuery

A timestamp is a counter used to represent date and time. It represents the number of seconds since 00:00:00 on January 1, 1970. It is also called a Unix timestamp. In web development, both PHP and jQuery provide functions for converting timestamps into readable datetimes.

PHP timestamp to time

In PHP, use the date() function to convert the timestamp to date format. This function takes two parameters, the first is the date format and the second is the timestamp. Here are some common date formats:

• Y: Four-digit year
• m: Month (01-12)
• d: Number of months Days (01-31)
• H: Hours in 24-hour format (00-23)
• i: Minutes (00-59)
• s: Seconds Number (00-59)

Sample code:

$timestamp = time(); //获取当前时间戳
$date = date("Y-m-d H:i:s", $timestamp); //将时间戳转换为日期时间格式
echo $date;

Output result:

2022-01-01 00:00:00

jQuery timestamp to time

In jQuery, We can convert timestamp to datetime format using $.format.date function. This function takes two parameters, the first is the timestamp and the second is the date format string. Here are some common date formats:

• yyyy: four-digit year
• MM: month (01-12)
• dd: number of months Days (01-31)
• HH: Number of hours in 24-hour format (00-23)
• mm: Number of minutes (00-59)
• ss: Seconds Number (00-59)

Sample code:

var timestamp = Math.floor(Date.now() / 1000); //获取当前时间戳
var date = $.format.date(new Date(timestamp * 1000), "yyyy-MM-dd HH:mm:ss"); //将时间戳转换为日期时间格式
console.log(date);

Output result:

2022-01-01 00:00:00

Note that in jQuery, Date.now()The function returns the number of milliseconds of the current time, while the time() function in PHP returns the number of seconds, so you need to multiply the timestamp in jQuery by 1000 to get the corresponding PHP timestamp. .

Summary

In web development, timestamps are used very frequently, and converting timestamps into readable date and time formats is a very common requirement. Both PHP and jQuery provide functions for implementing this function, and developers can choose to use them according to their needs.
